Mower Gearbox for Airport Mowers

Mower Gearbox


A mower gearbox is a mechanical device that transfers torque and rotation to the cutting blades of a mower. Mower gearboxes are essential components of airport mowers that help maintain the safety and appearance of airport runways by keeping grass and other vegetation in check. This article aims to discuss the various aspects of mower gearboxes for airport mowers.

Types of Mower Gearboxes

There are mainly two types of mower gearboxes: spindle gearbox and out-front gearbox.

Spindle Gearbox

A spindle gearbox is a type of gearbox that attaches to the mower deck and uses a pulley to transfer power to the blades. It is suitable for mowing small areas and has a lower maintenance cost than an out-front gearbox.

Out-front Gearbox

An out-front gearbox is a type of gearbox that is located beneath the mower seat and uses a drive shaft to transfer power to the blades. It is ideal for mowing large areas and has a higher maintenance cost than a spindle gearbox.

Components of Mower Gearboxes

Mower gearboxes consist of several components that work together to deliver power to the cutting blades.


The gears in a mower gearbox are responsible for transferring torque from the power source to the cutting blades. They come in various shapes and sizes, depending on the type of gearbox and the intended use of the mower.


Shafts are long, cylindrical components that transmit power from the gears to the cutting blades. They are usually made of steel or aluminum and are designed to withstand the high torque and rotational forces generated by the gearbox.


Bearings are components that support the shafts and gears in a mower gearbox. They reduce friction and wear between moving parts and help to extend the life of the gearbox.

Maintenance of Mower Gearboxes

Mower gearboxes require regular maintenance to ensure optimal performance and longevity. The following are some tips for maintaining a mower gearbox:

Check the Oil Level

Check the oil level in the gearbox regularly and change it as needed. Old or contaminated oil can cause the gearbox to overheat and wear out prematurely.

Inspect the Gears

Inspect the gears for wear and damage. Replace any worn or damaged gears to prevent further damage to the gearbox.

Clean the Gearbox

Clean the gearbox regularly to remove dirt, debris, and other contaminants that can cause damage to the gearbox components.
