How to Level a Mower Deck for a Toro


The first indication of an uneven lawn cut is an immediate call for action. A couple of things will cause a deck to cut unevenly. Bumping against an obstacle while operating the mower is common, while hanging the edge of the deck on a slope or incline is another possibility. In either case, a readjustment of the deck is necessary.

Step 1

Position the mower on hard, level ground. Attempting an adjustment of the deck on uneven ground will result in less than optimum results.

Step 2

Arrange the mower blades in a perpendicular position to the lawnmower. Measure from the tip of the outermost edge of both the left and right blade to the ground. A difference of 3/16 inch or less between the two measurements is acceptable.

Step 3

Locate the leveling brackets on the right- and left-hand side of the mower deck. On the low side, adjust the deck up by removing the hairpin and washer from the adjustment pin with needle-nose pliers. Rotate the leveling bracket to the next hole and re-insert the pin. Adjusting to a leveling hole nearer to the rear of the mower raises the deck. Holes nearer to the front of the mower lower the deck.

Step 4

Recheck the deck by measuring the distance between the blade tips and the ground as before. If the difference between the two is less than 3/16 inch, the mower deck will cut level.

Tips and Warnings

  • Wear gloves to help prevent pinching or cutting hands.
