Lawn mower gearbox

A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It consists of an engine, a walking wheel, a traveling mechanism, blades, handrails, and control components.

There are two power transmission belts on the power output wheel, which transmit the belt to the power transmission of the cutting system, called the cutting power belt, and the other is the traveling power belt.

A cutting power belt is coupled to the cutting system by the rotating wheel. When the pull switch is loose, the power supply is turned off. The side of the walking power belt is also equipped with a pressure roller. The pressure roller is connected with the cable switch. When the pressure roller is in this position, the belt remains in a relaxed state, and the engine power cannot be transmitted back. The wheel is connected to the gear box. The mower gearbox is a combination of several sets of gears that are adjusted by different gear combinations to achieve engine speed and direction of rotation. For the gearbox, the runner is its input power, and the gearbox combination is completed by the shift lever. This is the power output shaft of the gearbox, and the power is output to the walking system to complete the mower operation.

How to Properly Lubricate a Lawn Mower Gearbox


Keeping your lawn mower running smoothly means lubricating its gearbox regularly. If you've recently rebuilt your mower gearbox, you should change the oil every few thousand miles to avoid damaging the machine. However, lubrication isn't always enough to prevent mower gearbox wear. You also need to make sure that the oil level in the transmission is proper and that it is the correct color.


Mower transmissions combine multiple gears to provide power to the cutting system. The gearbox is then connected to a runner or shifter. The engine and gearbox are connected by a runner, allowing you to adjust the engine speed. After selecting the correct gears, could you check the alignment of the runner and the clearance of the blades? If the blades are too high, they may hit the shaft.


For lawnmowers, the Sunfield gearbox is a good choice. Sunfield, specializing in agricultural equipment parts, makes the gearbox. They are made from 20CrMnTi gear shafts and HT250 housings.


The transaxle is a single mechanical component that combines transmission, differential, and axle functions. This is genius because it combines all three functions into a single mechanical unit. The transmission is mounted at the rear end of the mower for the basic mower. The gearbox is connected to the drive axle by lever.


The gearbox is critical to the performance of the mower. The transmission helps the mower transfer power from the engine to the wheels. Gearboxes can range from simple to complex, but most mowers use hydrostatic or gear-driven transmissions. The basic transmission may have five forward gears and one reverse gear depending on the model. In contrast, a basic push mower transmission will have one gear speed. Higher-end models may have variable speed transmissions with variable slip or constantly variable transmission.


Locking differentials in ride-on mowers help prevent wheel slip. A locking differential prevents one wheel from slipping and the other from getting stuck. This allows the mower regain traction. Some garden tractors and lawnmowers are equipped with this type of transmission. In addition to zero-turn mowers, many brands also make larger commercial models with high-end features. Whether looking for a small zero-turn mower or a heavy-duty commercial unit, you'll want to pay attention to the model number.
