Mower Gearbox for Rotary Mowers

Mower Gearbox


A mower gearbox is an essential component in rotary mowers, which is responsible for transferring power from the engine to the blades. It consists of several gears and shafts that work together to control the speed and torque of the blades. In this article, we will discuss the key features, benefits, and applications of mower gearbox for rotary mowers.

Types of Gearboxes

There are two types of gearboxes used in rotary mowers: single-speed gearbox and two-speed gearbox. A single-speed gearbox has a fixed gear ratio, which means that the blade speed remains the same regardless of the engine speed. On the other hand, a two-speed gearbox has two gear ratios, which can be switched by the operator. This allows for greater versatility in cutting different types of grass and weeds.

Gearbox Components

A typical mower gearbox consists of several key components, including the input shaft, output shaft, gears, bearings, seals, and housing. The input shaft is connected to the engine, while the output shaft is connected to the blade. The gears and shafts inside the gearbox are responsible for transmitting power and controlling the speed and torque of the blade. The bearings and seals ensure that the gearbox operates smoothly and efficiently, while the housing protects the internal components from dust and debris.

Benefits of Mower Gearbox

The mower gearbox provides several benefits to the user, including:

  • Efficient power transmission
  • Control of blade speed and torque
  • Improved cutting performance
  • Reduced wear and tear on the engine and blade
  • Longer lifespan of the mower


Mower gearboxes are used in a variety of applications, including:

  • Lawn mowers
  • Golf course mowers
  • Park maintenance equipment
  • Roadside vegetation management
