An uneven cut by a lawn mower, commonly referred to as step-cutting, is a common occurrence and may be as a result of a malfunction in or wrong use of machinery. You can easily troubleshoot an uneven cut, if you are aware what you need to look for. Diagnosing a lawn mower should be done on a horizontal, level surface, similar to your driveway. Furthermore, both the engine and the blades should be inactive during the process of troubleshooting the lawn mower. This article addresses two key areas an ordinary homeowner can diagnose as far as an uneven mowing cut is concerned.
Because the wheels of the majority of walk-behind lawn mowers serve to fine-tune the height of the mowing cut, it’s a no-brainer that it should be the starting point when looking for problems. This involves checking the height of both the front and back wheels using a tape measure. Firstly, roll the lawn mower onto a flat surface, for example a concrete slab. In case the wheels don’t touch the ground, the problem could be that one of the wheels isn’t correctly adjusted or set at the same height as the rest. Find the wheel adjustors and properly adjust to the necessary wheel height. Additionally, inspect to see whether the front and back wheels are of a similar height. Using a measuring tape, take the perpendicular distance measurement from the ground to the mower deck at every wheel. Note that all these distances ought to be similar at every wheel.
Furthermore, the issue of inflatable tires may also be attributed to an uneven mowing cut. Inspect the pressure in every wheel. Add the recommended air pressure to those tires with low pressure because they often cause the lawn mower to slope and thus cut unevenly.
- Dirty blades
Generally, blades gather dirt, grass clippings and other types of items while cutting. Over time, the buildup tends to stick and cover the blades, thus affecting the quality of the grass cut. Using a blade cleaning kit, get rid of the buildup present in the blades in order to achieve a more level cut.
- Loose blades
Loose blades account for many of patchy or uneven mowing cuts. Inspect the blade’s position on a level ground by rotating the blades manually until they point vertically to the equipment and then measure the space between the blades and the surface on both the top left and top right sections of the lawn mower. The distance ought to be similar on both sides or else the blades are misaligned. Repairing it calls for a visit to a professional lawn mower repair contractor.
