Why Zero-turn?

WHY CHOOSE A ZERO TURN?


ZERO TURN TIME SAVINGS

You can cut your mowing time in half using a zero turn mower instead of a traditional riding lawn tractor. Here are some of the time-saving features of zero turn technology:

Maneuver Around Obstacles

The maneuverability of zero turn mowers allows you to easily mow around trees, flower beds and other obstacles in your yard more easily than with a steering wheel vehicle such as a riding lawn tractor.

Drive at a Faster Speed

Zero turn mowers are designed to cut grass nearly twice as fast as traditional lawn tractors so your straight line mowing speed is improved. A typical lawn tractor cuts at a speed of 3-4 mph while a typical zero turn mower cuts at a speed of 5-8 mph.

Mow in a Single Pass

When you get to the end of your yard and have to turn around and come back, you literally can spin 180 degrees and come straight back without having to back up and cut the strips of grass you would miss when making the turn with a lawn tractor.

Eliminate Follow-Up Trimming

With an unobstructed view of the cutting deck, zero turn mowers make it easy to cut very close to your trim edges – you can nearly eliminate the need to trim hard-to-reach areas with a push mower or a string trimmer after you've finished mowing.​​


EASY AND ENJOYABLE TO DRIVE

Without a steering wheel, a zero turn machine may look intimidating to drive but most people become comfortable with the way it handles after just a few times mowing their lawn.

Steering a zero turn mower is easy. In fact, it is not that different from steering a shopping cart.

  • How to make left turn with Zero Turn
  • How to make right turn with Zero Turn

  • Forward: Push the handles forward.
  • Reverse: Pull the handles back.
  • Right Turn: Push the left handle forward.
  • Left Turn: Push the right handle forward.
  • Stop: Bring the handles back to neutral.

The key to driving in a straight line is to assure that the same amount of pressure is applied to each lever.​​
