When I talk to farmers and agricultural machinery buyers about a large combine harvester, I usually do not start with horsepower. I start with the field.

What crop are you harvesting? How many hectares do you need to cover? Is the field flat or uneven? Do you need to move the machine between farms? Are you mainly harvesting wheat, rice, corn, soybean, sunflower, or several crops during the same year?

These questions sound simple, but they can completely change the right machine configuration.

The Wheel Harvester GK120 is a machine I would normally discuss with customers who need a higher-capacity harvesting solution for medium and large fields. LOVOL describes the GK120 as a wheel combine harvester using a single longitudinal axial-flow threshing and separation system. Its published specifications include a 220 PS engine configuration, 5,340 mm cutting width, 12 kg/s feeding capacity, 7,000 L grain tank, and 1.0–2.0 hm²/h working efficiency. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

That combination tells me something important right away: the GK120 is not designed simply to be a bigger version of a small farm combine. It is built around higher harvesting capacity and longer working periods in medium and large fields.

At Ganglong Heavy Industry Technology (Hefei) Co., Ltd., I work with customers who need agricultural machinery for real farming projects, including international buyers looking for complete machines, attachments, inspection, shipping, and delivery arrangements.

Together with Hefei Ganglong International Trade Co., Ltd., we supply agricultural machinery as well as construction machinery, mining machinery, and matching equipment. For LOVOL products, our role is to supply and arrange the equipment according to the customer's requirements. We do not describe third-party LOVOL equipment as our own manufactured product.

1. What Is the LOVOL GK120 Wheel Harvester?

The LOVOL GK120 Wheel Harvester is a large wheeled combine harvester developed for grain harvesting operations. LOVOL's official product information says the GK series is designed for medium and large plots and can be used for wheat, rice, soybean, corn, sunflower, foxtail millet, buckwheat, sorghum, and other crops. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

In practical terms, the machine brings several harvesting jobs into one working process.

The header cuts and gathers the crop. The feeding system moves the crop into the threshing section. The longitudinal axial-flow drum then handles threshing and separation. After that, the cleaning system removes unwanted material from the grain. Clean grain is stored in the grain tank until it is ready to unload.

That sounds straightforward, but a large combine has to keep all of these systems working together while moving through the field.

The published GK120 configuration uses a single longitudinal axial-flow drum. LOVOL also publishes a 12 kg/s feed capacity and a 5,340 mm cutting width for the English-language GK120 specification. The same page lists a 12,500 kg total weight and overall dimensions of 9,520 × 5,700 × 4,100 mm. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

Another official LOVOL regional page publishes a GK120 configuration with a 220 PS engine, 5,340 mm cutting width, 12,190 kg vehicle weight, 7,000 L grain tank, and 1.0–2.0 hm²/h working efficiency. It also describes a dual-power 185/220 PS Yuchai engine setup. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

This is why I always confirm the exact market configuration before an international order. The model name may be the same, but the specification shown on one regional page may not be identical to another version.

Source: LOVOL official GK120 product information and regional LOVOL product pages. Specifications vary by configuration and market and should be confirmed before ordering. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

For me, the important point is not to take one number and assume it tells the whole story. A combine harvester is a complete working system. Engine power, header width, feed capacity, threshing structure, cleaning area, grain tank capacity, unloading speed, field conditions, and operator settings all affect the final result.

2. How the GK120 Wheel Combine Harvester Works

If you have never operated a combine before, the inside of the machine can look complicated. But the basic process is actually quite easy to follow.

The first stage is cutting.

The header moves through the standing crop and cuts it. The published GK120 configuration has a 5,340 mm cutting width, which gives the machine a broad harvesting path. A wide header can help cover more land per pass, especially when the field is large and crop conditions allow the machine to keep moving at a useful speed.

The crop then enters the feeding system.

From there, it moves into the threshing and separation section. The GK120 uses a single longitudinal axial-flow drum. Instead of separating grain through a short, traditional threshing route, the crop moves through the long axial-flow system while threshing and separation continue along the drum.

LOVOL's official information also describes a large-diameter axial-flow separation technology. One regional LOVOL page gives a drum size of approximately 660 mm × 3,015 mm and states that drum speed can be adjusted within a range of about 300–900 rpm. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

Why does drum adjustment matter?

Because crops are never exactly the same.

Wheat harvested on a dry afternoon can behave differently from wheat harvested after a humid night. Corn, soybean, rice, and sorghum also have different crop structures. The operator needs room to adjust the machine rather than forcing every crop through one fixed setting.

After threshing and separation, the grain moves toward the cleaning system. The GK120 uses an air-and-screen cleaning system. Screens help separate the grain from material of different sizes, while airflow helps remove lighter chaff and unwanted material.

The cleaned grain then goes into the grain tank.

Once the tank reaches the required level, the unloading system transfers the grain into a trailer, truck, or other receiving vehicle.

This is where a large grain tank becomes useful. LOVOL's published GK120 regional specification lists a 7,000 L grain tank. Another English product page shows a 500 L tank-volume value that appears inconsistent with the regional GK120 specification, so I would not use that isolated figure for an international quotation without confirming the current machine version. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

In other words, the grain tank figure is something I would confirm before the customer places an order, rather than simply copying an online specification.

3. Main Features I Look at on the GK120

Large 5.34-Meter Cutting Width

One of the first things I notice about the GK120 is the 5,340 mm cutting width.

For a large field, this matters. If the crop is uniform and field conditions are suitable, a wider header allows the machine to cover more crop with each pass. That can reduce unnecessary turns and help make better use of the machine's available power.

But I always add one warning here: bigger is not automatically better.

If the field is very small, narrow, irregular, or difficult to access, a large header may not be the easiest choice. That is why I ask customers about actual field size before recommending the configuration.

High Feed Capacity

The published GK120 feed capacity is 12 kg/s. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

Feed capacity gives us a useful idea of how much harvested material the machine is designed to process through the harvesting system. It is not the same as guaranteed field output because crop yield, moisture, crop density, operator settings, and field conditions all matter.

Still, the 12 kg/s specification places the GK120 in a higher-capacity class than smaller LOVOL wheel combines.

Single Longitudinal Axial-Flow System

The GK120's single longitudinal axial-flow system is one of its defining features.

The crop continues moving along the axial-flow drum while threshing and separation take place. LOVOL has designed the GK series around this technical route for medium and large plots. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

From my point of view, the benefit is mainly about maintaining a continuous crop flow through a high-capacity harvesting system.

Adjustable Drum Speed

One LOVOL regional product page states that the GK120's threshing drum speed can be adjusted continuously from approximately 300 to 900 rpm. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

This gives the operator more control when crop conditions change.

For example, if the crop is difficult to thresh, the machine may need a different setting than when the crop is dry and easy to separate. The exact setting should be determined according to the crop and operating conditions.

Hydrostatic Drive

LOVOL's regional GK120 information describes a hydrostatic walking system with stepless speed adjustment. It also identifies a Danfoss hydrostatic drive unit in the published configuration. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

In simple language, the operator can adjust travel speed smoothly instead of being restricted to a small number of fixed mechanical speeds.

This is useful during harvesting because field conditions are not always uniform. The operator may want to slow down in a heavy crop and increase speed when crop flow becomes lighter.

Four-Wheel Drive and High Ground Clearance

LOVOL also describes reinforced four-wheel drive, increased ground clearance, and wider tires for the GK120 regional configuration. These features are intended to improve the machine's ability to move between fields and work under different road and field conditions. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

For an overseas buyer, I consider this especially relevant because road conditions can be very different from one country to another.

4. GK120 Compared with Other LOVOL Wheel Combine Harvesters

When a customer asks me about the GK120, I usually put it next to smaller LOVOL wheel combine models. That gives us a much clearer picture of what the machine is actually designed to do.

Source: LOVOL official and regional product information for GM80, GM100 and GK120. Published specifications may differ between configurations and markets. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

The difference is easy to see.

The GM80 and GM100 are smaller machines with narrower headers and lower feed capacities. The GK120 moves into a larger harvesting class with a 5.34 m header and 12 kg/s published feed capacity.

This is why I normally discuss the GK120 with customers who have medium or large fields, higher annual harvesting volumes, or agricultural machinery service businesses.

LOVOL's regional product description specifically says the GK series is developed for medium and large plots. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

Again, though, I would not select the machine just because the specifications look larger. A machine should match the job. A smaller farm with small, irregular fields may not benefit from a large combine in the same way as a large agricultural contractor.

5. What Crops and Applications Suit the GK120?

Wheat Harvesting

Wheat is one of the most common applications I would discuss for the GK120.

Large wheat fields are exactly where a wide header and high-capacity harvesting system can make practical sense. The 5.34 m cutting width allows a broad working path, while the 12 kg/s published feeding capacity provides a useful reference for the machine's processing capability.

However, actual harvesting performance depends on wheat yield, moisture, crop height, straw condition, field layout, and operator settings.

Rice Harvesting

LOVOL also lists rice among the crops that the GK120 can harvest. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

Rice harvesting can be more demanding because fields may have wet or soft soil. For a rice project, I would check the local field conditions carefully before confirming the machine configuration.

Ground conditions affect not only traction but also field access, tire performance, turning, and transportation between plots.

Corn Harvesting

Corn is another crop listed in LOVOL's GK120 product information.

For corn grain harvesting, the correct header and threshing components are important. LOVOL's regional description explains that the GK series can harvest corn and other grain crops by replacing the header and relevant threshing components. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

This is an important point for buyers: the base harvester and the crop-specific attachment should be considered together.

Soybean Harvesting

Soybean fields can vary a lot from one region to another. Plant height, moisture, soil conditions, yield, and harvest timing all affect machine settings.

LOVOL lists soybean as one of the target crops for the GK120. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

For an international order, I would confirm the customer's soybean variety and local harvesting conditions before discussing the final attachment and operating setup.

Sunflower, Sorghum and Other Grain Crops

The official LOVOL English page also lists sunflower, foxtail millet, buckwheat, and sorghum among the crops for the GK120. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm))

This broad crop range is useful for agricultural contractors who may need to work across several crop seasons.

But multi-crop capability does not mean that one fixed setting works for everything. The header, threshing components, drum speed, concave adjustment, cleaning settings, and operating speed may need to change with the crop.

6. Technology and Design Details I Think Buyers Should Understand

There is a lot of technical language around modern combine harvesters. I prefer to translate it into something useful.

Axial-Flow Threshing

The GK120 uses a single longitudinal axial-flow system. The crop moves along the drum, and threshing and separation continue through the longer working path.

For a high-capacity machine, this design helps maintain a continuous material flow. LOVOL's published regional data gives a 660 mm × 3,015 mm drum and an adjustable speed range of around 300–900 rpm. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

Cleaning System

After threshing, the machine still has to clean the grain.

The GK120 uses an air-and-screen cleaning system. The screen handles grain and material separation while the air stream helps remove lighter particles.

Good cleaning is not only about the hardware. It also depends on correct adjustment. If the fan setting or screen setup is not suitable for the crop, grain loss or excessive impurities can become a problem.

Hydrostatic Speed Control

The hydrostatic drive gives the operator more flexible speed control. This is useful because the ideal travel speed is not always the same.

In a heavy crop, slowing down can help keep the harvesting system from becoming overloaded. In a lighter crop, the operator may be able to work faster.

Large Grain Tank

The regional GK120 specification lists a 7,000 L grain tank. ([sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

For large-field operations, this can reduce the frequency of unloading stops. Less interruption can make the harvesting process easier to organize, especially when the receiving truck or trailer is already working alongside the harvester.

I always remind customers, however, that the grain tank is only useful if the unloading system and receiving vehicle are planned properly. The combine and grain transport equipment need to work as a team.

7. How I Handle an International GK120 Order

When a customer asks me about a GK120 Wheel Harvester for sale, I do not immediately send a standard quotation.

I first collect the information needed to understand the project.

The first question is crop type.

The second is field size.

The third is working environment.

Then I ask about the expected annual working hours, local road conditions, required attachments, destination country, preferred shipping port, and any special inspection or documentation requirements.

Once those details are clear, I can check the suitable LOVOL configuration.

This is particularly important with the GK120 because LOVOL publishes different specifications across regional product pages. For example, the current English page lists a WP7G260E302 engine and 12,500 kg total weight, while another official regional page describes a 220 PS configuration with 12,190 kg vehicle weight and 7,000 L grain capacity. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm); [sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

I would rather spend a little more time confirming the exact version than give a customer a specification that belongs to another market.

Pre-Shipment Inspection

Before delivery, we can arrange checks according to the order requirements.

These checks can cover the engine, hydraulic system, electrical system, tires, harvesting functions, grain unloading system, attachments, working controls, and required documents.

If the customer has a specific inspection checklist, we can discuss it before shipment.

Packing and Loading

A complete combine harvester is normally transported internationally by sea. Before loading, the machine is prepared and secured for transportation.

Loose parts and accessories can be packed separately in cartons or wooden cases according to the product and shipping requirements.

For smaller spare parts and accessories, air freight or express delivery may be suitable when the customer needs faster transportation.

Source: Ganglong Heavy Industry Technology (Hefei) Co., Ltd. international agricultural machinery supply and delivery process information provided for this product page.

Payment is commonly arranged by T/T, with a deposit before order processing and the balance before shipment. The exact payment terms are agreed between both parties.

The production and preparation period is also confirmed according to the selected LOVOL model, configuration, order quantity, machine availability, inspection requirements, and shipping schedule.

8. Why I Work with Customers Through Ganglong

Ganglong Heavy Industry Technology (Hefei) Co., Ltd. was founded in 2013. Together with Hefei Ganglong International Trade Co., Ltd., we operate as a comprehensive industrial enterprise covering equipment R&D, manufacturing, testing, customization, sales, leasing, and international trade.

Our product range includes construction machinery, mining machinery, agricultural machinery, and matching attachments.

We also have our own HKLOONG brand covering Excavators, loaders, Backhoe loaders, and swamp excavators. At the same time, we provide complete machine sales and leasing services for brands including Hitachi, SANY, Lonking, Hyundai, XCMG, SHANMON, and LOVOL.

When we supply LOVOL equipment, we are careful about the distinction between manufacturer and supplier. The GK120 is a LOVOL product, while Ganglong acts as the machinery supplier and international trade partner handling the customer's order requirements.

I believe this matters because international machinery buyers need clear information. They need to know who manufactures the machine, who handles the export order, what configuration is being supplied, what documents are included, and how the machine will reach the destination country.

Our international trade team has experience with construction machinery, mining machinery, and agricultural machinery. We have served customers in Asia, Africa, America, and other international markets.

For me, the most useful part of this work is helping customers turn a general request into a clear machinery plan.

A customer might begin with a message saying, “I need a 220 HP combine harvester.”

That is only the beginning.

I then need to know whether the machine will harvest wheat or corn. How large are the fields? How wet is the soil? What kind of transport truck will receive the grain? Does the customer need one header or several? What is the destination port? What documents are required?

Once we answer those questions, the equipment choice becomes much clearer.

13. How long does it take to prepare a GK120?

The preparation period is not identical for every order. It depends on the selected configuration, machine availability, order quantity, inspection requirements, attachments, and shipping schedule. I recommend confirming the actual delivery schedule before the order is finalized.

Final Thoughts: Is the GK120 the Right Size for Your Farm?

When I look at the Wheel Harvester GK120, the first thing I notice is that it is designed around capacity.

A 5,340 mm cutting width, 12 kg/s published feed capacity, single longitudinal axial-flow threshing system, hydrostatic drive, air-and-screen cleaning, and large grain storage configuration all point toward medium and large-scale harvesting work. ([en.lovol.com](https://en.lovol.com/agricultural/pro-detail-812.htm); [sp.lovol.com](https://sp.lovol.com/agricultural/pro-detail-1323.htm))

For farmers and agricultural contractors, that can be useful when the goal is to cover a lot of land during a short harvesting window.

But I would still start with the field rather than the machine.

If the farm has large, open fields and high annual harvesting demand, a high-capacity combine can make practical sense. If the fields are small and irregular, a smaller machine may be easier to operate. If several crops need to be harvested, the correct headers and harvesting components become especially important.

The same rule applies to international buyers.

I do not want to sell a customer a machine simply because the specification looks impressive on paper. I want to know what the machine will actually do after it arrives.

That means checking the crop, field conditions, annual working volume, attachments, transport requirements, destination, inspection, and local operating environment before confirming the order.

For customers searching for a LOVOL GK120 Wheel Harvester, GK120 Wheel Combine Harvester, or a high-capacity GK120 Grain Harvester, Ganglong can help with the complete international supply process, from configuration confirmation and inspection to packing and shipping.

For me, the right agricultural machine is not simply the one with the biggest numbers.

It is the one that fits the field, the crop, the workload, and the way the customer actually plans to use it.
