Deck Belt

On every riding lawn mower you will have a deck belt; this is a compulsory part that forms a connection between the blades and the crankshaft of your riding lawn mower. This also helps to ensure that this part turns.

Over time, and as you use your Toro Timecutter, this part will wear and you will be able to tell this by looking at the condition of the rubber. When it begins to show signs of cracking, this tells you that it’s time to replace it. While it can be tempting to leave it, a cracked deck belt will result in interruptions to its movement and therefore, affect the performance of the mower.

Idler Pulley

The idler pulley, or deck idler pulley, is there to ensure correct tension for the drive belt as well as guiding it. In order for it to function correctly, the idler pulley must wrap around quite a few parts of the engine including the water pump, the steering pump, the alternator and several others.

What Is The Working Mechanism Of The Drive Belt?

The drive belt is a very important part of your Toro Timecutter and any other petrol powered lawn mower. It’s main job is to make sure that power is transferred to the various parts of the lawn mower.

Within the engine shaft, radial torque builds up and the drive belt makes sure that this torque is moved towards the input shaft.

When this happens, the torque causes the lawn mower to run smoothly and reliably. As well as this, the drive belt makes sure that the mower moves forward and that the blade is spinning.

How Does The Drive Belt Transfer Power?

So, we now understand that the drive belt is responsible for transferring power but a lot of lawn mower owners don’t understand how this happens.

It works because of how the drive belt runs on your lawn mower. There are pulleys that attach at the input shaft and at the engine shaft. When you start the lawn mower engine up, the belt turns the engine shaft followed by the input shaft as it transmits energy.

It is the first pulley that is responsible for making the drive belt move, when this happens, it causes the second pulley to start moving too. You might see it as something of a pattern, as follows:

  • The engine fires up
  • The engine shaft turns
  • The first pulley turns
  • The drive belt starts moving
  • The second pulley turns
  • The transmission shaft turns

There are several reasons that the drive belt on your Toro Timecutter might keep coming off. However, the most common reasons are because certain parts are worn out. These might include the bearings, spindle housing, brackets, belt keepers or other parts. In some other cases, the drive belt may be clogged with debris which will reduce the tension.

Final Thoughts
