Exmark Comprehensive Maintenance Schedule and Parts for Lawn Mowers

Cutting Leaves:

•After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than one pass over the leaves.

•For light leaf coverage, set all the wheels at the same cutting height setting.

•If there are more than 5 inches (127 mm) of leaves on the lawn, set the front cutting height 1 or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the lawn mower deck.

•Slow down your mowing speed if the lawn mower does not cut the leave finely enough.

•If you mow over oak leaves, you can add lime to the grass in the spring to reduce the acidity of the oak leaves.
