Rotary cutter gearboxes are an essential part of rotary cutters used for a variety of agricultural tasks such as mowing grass or chopping crops. It is an essential gearbox responsible for transmitting the power generated by the tractor’s power take-off to the blades of the rotary cutter. A gearbox is a mechanism formed by the meshing of one or more pairs of gears. With the efficient gearbox, the blade can rotate at high speed to cut dense vegetation quickly and efficiently. Rotary cutter gearboxes are typically constructed of heavy duty cast iron or aluminum to withstand the harsh operating conditions and loads encountered during cutting. The gearbox is composed of input shaft, output shaft, gears, bearings, seals and other components.

The Rotary Cutter Gearbox for the agricultural industry is a power transmission unit designed specifically for agricultural machinery, mainly used to drive rotary knives for efficient cutting operations (e.g. grass cutting, straw crushing, brush clearing, etc.). Its core function is to convert the power from the tractor or other power sources into high torque, stable speed mechanical energy suitable for agricultural cutting, while adapting to the complex field environment.
Functions of GTM Rotary Cutter Gearbox
1. Power transmission and speed regulation
Through the gear set to convert the high speed (usually 540/ RPM) of the tractor power output shaft (PTO) into low speed and high torque suitable for cutting, to ensure that the tool maintains stable power when the load is changing (e.g. cutting thick straw, weeds).
It supports multi-speed regulation to suit different crop densities or terrains (e.g. steep slopes, wetlands).
2. Durability and protection
Made of high-strength cast iron or alloy steel with anti-rust surface treatment, resistant to corrosion by mud, water, gravel and plant sap in the field.
Sealed design prevents dust and debris from intruding into the gearbox (e.g. IP67 level protection), prolonging the life of bearings and gears.
3. Safety protection mechanism
Integrated overload clutch or shear bolt cuts off power in case of tool jamming to prevent gearbox damage.
GTM are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Some models are equipped with shock absorbers to reduce the impact on the mechanical structure during operation.
Application of GTM Rotary Cutter Gearbox in Agricultural Scenarios
1. Grass cutting and straw crushing
Drive the rotary blade to cut grass, straw or cover crops (e.g. cornstalks), the blade speed can be adjusted to control the size of crushing (coarse crushing to return to the field or fine crushing to feed).
2. Shrub and bramble clearing
For cutting brush at the edge of orchards and woodlands, the gearbox provides high torque to cope with hard woody stalks.
3. Farmland preparation and stubble treatment
Combined with the disc knife or dumping knife, it can quickly clean up field stubble (such as rice stubble, wheat stubble) in preparation for planting or plowing.
4. Orchard and vineyard management
The low profile gear box design is suitable for orchard machinery, and it can complete the cutting of weeds between rows in a narrow space.
Design of GTM Rotary Cutter Gearbox
1. PTO Drive Adaptation
Directly connects to tractor power output shaft, supports standard speed (540/ RPM) and quick-change couplings for quick installation and removal.
2. Modular blade set
Gearbox output shaft can be adapted to different knives (such as Y-type knives, hammer blade knives), through the replacement of blades to achieve multi-functional operations (cutting, crushing, spreading).
3. Terrain adaptability
The floating gearbox design allows the cutter to adjust its height automatically with the undulation of the ground, avoiding knives colliding with hard objects (e.g. stones).
4. Maintenance Convenience
The oil filling hole and oil drain valve are external, which is convenient for lubrication and maintenance in the field; some models support maintenance-free bearings.
Commonly used equipment
Forage cutting and sunning machine: Gear box drives multiple knives, cutting and spreading forage grass synchronously.
Straw Returner: High-torque gear box drives heavy-duty hammer blades, crushing corn stalks and returning them directly to the field.
