When should you make steering adjustments on your mower?

  • Reduced Speed

This could be caused by multiple reasons but steering is one of the main issues that can affect the speed of your mower especially if you’re the type who loves hitting the maximum speed of your mower.

  • Veering towards on side

Your mower’s ideal path is moving on a straight line. When your cutting path is moving askew even when your steering controls are leveled, you know that you need to calibrate your steering.

Before you adjust your steering make sure that your mower is off and there are no moving parts. Park your steering in a hard level surface rather than out on the lawn where the ground may be uneven.

  • Tire Repair

Your tire may be one of the reasons why your mower is turning to one side, your tires need to have the same amount of pressure. To correct this issue:

  1. Inspect your front and rear tires:
    • Check if all of your tires have the same amount of pressure. 
    • See if the tires have any holes or any signs of advanced wear or tear.
  2. Since your mower have two sets of wheels, each pair need to have the same amount of pressure, if not, then use a tire inflator and pump air into the slightly deflated tire

TIP: Make sure you never hit the maximum pressure in your zero-turn's tires, don’t try to add air to all of the wheels especially of others have proper air pressure. Simply pump air into the problematic tire and you’re good to go.

  • Adjust Wheel Tracking

Another reason why you’re mower isn’t going straight is due to one drive wheel turning slower than the other.

This can be caused by a jam on the wheels or that you need to adjust the sluggish wheel by speeding it up or slowing the other wheel down.

  1. Inspect the tire where your mower is veering towards and see if there are any obstructions on the tire. Remove any of the obstructions and check your steering levers or lap bars.
  2. Push the lap bars outwards and look for a bolt and nut fastened at the foot of your lever. If the nut is loose, retighten it.
  3. If retightening doesn’t do anything, try adjusting the nut:
    • Decrease the steering lever travel by turning the bolt clockwise
    • Increase the steering lever travel by turning the bolt counter-clockwise
  • Steering Lever Adjustments
