Step 1 – Are both sides of the mowing deck attached well to the frame and none of the mowing deck sides sag down due to a lost pin and its lock washer?
If Yes – Reinstall and secure a mowing deck holding pin and its locking washer.
If No – Proceed to Step 2.
Step 2 – Is it the first cut of the season or the grass is very high?
If Yes – Raise mowing height level and let the mower complete a full cycle (2-3 days).
If No – Proceed to Step 3.
Step 3 – Are there wheel digging-in signs on the lawn?
If Yes – Proceed to Step 4.
If No – Proceed to Step 5.
Step 4 – Does the front wheel rotate freely on its axle, rolling-wise (green arrow on picture below) and against mower’s chassis, pivoting (red circle on picture below)?
If Yes – Proceed to Step 5.
If No – Try to release the wheel. There may be debris, long weeds or mulch collected there that prevent the wheel’s free rotation or pivoting. Proceed to Step 5.
If front wheel movement cannot be freed, remove the front wheel for thorough cleaning. If it doesn’t help, Replace the Front Wheel.
Step 5 – Is one of the blades (or both) worn or dull?
If Yes – Replace Worn Blade(s).
If No – Or if this does not resolve the problem, proceed to Step 6.
Step 6 – Are the mowing motors shafts bent?
If Yes – Replace Bent Shaft Mower Motor(s).
