What to Consider Before Buying a Lawn Mower Tractor?

Typically, if you have a lawn larger than half an acre, the best investment to make when choosing a mowing tool is buying a riding mower. On the market, there are many types of riding mowers available, but a versatile and popular machine is the lawn mower tractor.

If you decide to buy a lawn mower tractor, you should consider two important factors, the grade of the tractor and its size.

There are two grades of lawn tractors, entry-level and mid-grade. The entry-level typically have single-cylinder engines with lower powers. These machines are not exactly suited for mowing lawns larger than 1.5 acres and most of the times they have manual transmissions, which tend to be more durable but limit the speed control.

Mid-grade lawn mower tractors are generally equipped with twin-cylinder engines that are suitable for lawns larger than 1.5 acres. These lawn tractors can usually be used with lightweight attachments, such as mulching or bagging kits, and have hydrostatic transmissions offering more control over the speed adjustments.

Even if the mid-grade lawn tractors are more expensive compared to the entry-level ones, I recommend investing in a mid-grade lawn tractor because they are more versatile and cut the grass faster and better.

Besides choosing the right grade, you should also consider a few other things before deciding what lawn mower tractor to buy.

  • Cutting deck width;
  • Lever or pedal-operated transmission;
  • Compatible attachments;
  • Adjustable seat;
  • Adjustable cutting height.

For a faster start, the engine is equipped with an electronic ignition and it features cast-iron sleeves for a longer lifespan. For a better fuel and power management, the engine also boasts the convenient overhead valves.

The mower’s smooth underside and dual-stage E-coat powdered coating prevent the grass buildup and protect the deck from rust.

If you want to keep mowing while driving the lawn tractor in reverse, the D125 allows you to do so. This lawn mower tractor is equipped with a Reverse Implement Option system that will let you continue mowing while driving in reverse.

To activate this option, you have to stop the tractor, push the RIO button and operate the shift lever into the reverse mode, then release the button to keep mowing while driving backward.
