How To Repair Lawn Tractor With Excess Vibration

Blade
If your lawn tractor is vibrating excessively, first stop the engine immediately. It could be a sign that the mower blade is damaged or simply out of balance. Possibly causes for a blade being out of balance are a damaged blade, or a blade that has been improperly sharpened. Perform a simple wall test to find out if the blade is balanced: remove it and hang it on a wall with a nail through the centre hole. If the blade is off-balance, the heavier side of the blade will drop lower than the lighter side. If the test shows that the blade is damaged or out of balance it should be replaced. Continuing to use your lawn tractor with an out of balance or damaged blade could cause irreparable damage to the engine, and in some causes could cause injury to the operator.

Blade Spindle
Another cause for excessive vibration during the operation of a mower is that the blade spindle is bent. Much like damage to the blade, this can be caused by the mower suddenly striking something solid that it is not able to move past (rocks or a tree stump, for example). This sudden stop can cause damage both to the blade as well as the spindle that it attaches to. A bent spindle (even one that is just slightly bent) can cause excessive vibration when the mower is running, as the spinning blade will be unbalanced. This can be dangerous if not addressed immediately. If you believe your blade or spindle has been damaged and it is causing excessive vibration while operating the mower, discontinue use immediately and inspect the blade and spindle for damage. The machine should not be used until this issue is fixed.
