Deck Leveling & Cutting Height
There are 4 primary adjustments that should be made
prior to actual field operation:
prior to actual field operation:
•

•
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance, and
longer blade life. The following tools will be needed:

Place a level on the cutter deck as shown. Manually
adjust one or both lower 3-point lift arms until deck is

IMPORTANT: The front blade tip should be lower
than rear blade tip by approximately 1". The cutter is
subject to continuous material flow under the deck if
the rear blade is at the same height or lower than the
front blade causing horsepower loss, grass clumps,
blade wear, and frequent blade sharpening.
