How to Repair the Height of a Lawn Mower

Allow your lawn mower to come to a complete stop and put it in park. Disengage its blades and then cut the engine. Remove the keys from the ignition.

Sit in the mower's seat and grip the deck lift lever on the side of your machine. Move the deck lift lever to its middle position.

Open the lawn mower's front engine hood and take out the thin, black ignition wire from the rear of the spark plug before proceeding.

Put on a pair of gloves and rotate the blade nearest to the discharge shoot on your lawn mower. This shoot is on the bottom of the mower, parallel with the rest of the deck. Measure the front of the blade from its tip to the ground level.

Measure the blade from its rearmost part to the ground in the same manner.

Find the hex nut near the mower's suspension arm on the machine's bottom. Use a socket wrench to tighten or loosen this hex nut in order to level the front-to-rear orientation of the mower's blades, depending upon what your measurements indicated. Loosening the hex nut will lower the front of the deck in relation to the rear, while tightening the nut will raise the front of the deck.

Rotate the perpendicular blades on the mower to access the tips for measurement. This adjusts the deck from side to side.

Locate the lawn mower's hangar bracket. Find it on the left side of the machine's bottom, closely nestled against the perpendicular blades. There is a hex bolt on the hangar bracket. Loosen it with your socket wrench.

Measure the perpendicular blades from blade tip to ground level as you did with the mower's other blades. If they appear out of alignment, alter the adjustment gear on the hangar bracket with your socket wrench. Tighten its bolt to raise the side of the deck or loosen it to lower the deck.

Retighten the mower's hex bolt when you have completed adjustments.

Connect the ignition wire back into the mower's spark plug and close the hood.
