SERVICE AND ADJUSTMENTS TO LEVEL MOWER Ensure tires are properly inflated to the PSI shown on tires. If tires are over or under inflated, it may affect the appearance of your lawn and lead you to think the mower is not adjusted properly.

A FRONT-TO-BACK ADJUSTMENT (See Figs. 31 & 32) IMPORTANT: Deck must be level side-to-side.

CAUTION: Blades are sharp. Protect your hands with gloves and/or wrap blade with heavy cloth. • Raise mower to highest position. • Position blade so the tip is pointing straight forward. Measure distance (B) to the ground at front and rear tip of the blade. • If front tip of blade is not 1/8" to 1/2" (3,1 to 12,7 mm) lower than the rear tip, go to the front of tractor.
