How Lawn Tractors Work

What is a lawn tractor?

A lawn tractor is what you think of when you hear “riding mower”. It is a mid-size tractor with a steering wheel. Often times, different attachments can be put onto a lawn tractor, including a mowing deck that is located under or in front of the tractor. The tractor usually has a speed lever or a pedal.


  • Four wheels
  • Steering wheel
  • Engine under the hood
  • Removable deck located under the the tractor

 How it Works:

  • Put the key in the ignition and turn it to the start button to start the engine
  • The mower can be driven once the engine is on
  • Lawn tractors have many potential attachments such as baggers, mowers, plows, blowers, sweepers, and carts. If properly attached, the PTO (power take-off) takes power from the engine and uses it to run any attached items.
  • The mower’s speed is controlled either with levers or pedals
  • The blades rotate under the deck and cut the grass
  • The deck can typically be lifted to traverse areas that can potentially harm the mower

    My husqvarna driving mower will not start. I thought it was a dead battery so I replaced it. It took a while to get it started but it did kick over and run for a few minutes. As soon as I pulled the steering to the left, it died. It would not start at all as if it suddenly had a dead battery again. My neighbor and I found a burned out fuse and replaced it. It fired right up but blew the fuse as soon as I turned the wheel the slightest bit to the left again. I cannot find a short or a loose wire anywhere. Any ideas of what could be blowing the fuse?

    Hi – I was wondering if you could point me in the right direction. I have a John Deere L110 tractor with a 42″ Deck. When I push up on the lever (PTO arm) to get the blades cranking, I get nothing.

    The main pulley on the underneath of the engine spins away just fine. You can see the PTO cable and spring from the Lever arm moving and trying to engage the idler pulley on the idler arm bracket but that pulley doesnt seem to move enough to engage the belt to the rest of the pulleys.

    Any suggestions to fix this would be greatly appreciated!!!! Thanks!
