Blade Adjustment of Reel to Bed Knife

Always set the parking brake, shut off the power
unit engine, remove the ignition key, and ensure
all moving parts have stopped before checking
mower deck or blade condition, or attempting
any repair or adjustment.
Never make an adjustment with the engine running.
Contact with the reel, bed knife, or other sharp
objects may result in personal injury.
The reel is adjusted properly when, upon inserting 2
pieces of newspaper between the blade and the bed
knife, both pieces of newspaper are cut. If both
pieces are not cut, or if contact is present, the reel
must be adjusted by following these procedures.

Discharge Deflector Shield Adjustment

The reel discharge deflector shields on the reel
mower can be opened or closed to discharge clip-

To discharge to the front: Fully close the deflector
shields. This will achieve a better appearance when
cutting short amounts of grass.
To discharge to the rear: Open the deflector shields
to best enable clippings to exit the cutting unit.
Opening the shields too far (particularly in dry condi-
tions) may result in excessive build up of clippings in
the radiator screen or power unit frame. Only open
the deflectors to the extent that the conditions require.

Cutting Unit Offset

The reel mower is equipped with an offset capability
of 6 inches. The standard position is with the cutting
units centered on the power unit. To offset the cut-
ting units to the left, remove the 8 bolts that fasten
the hitch frame to the reel mower main frame. Move
the frame the desired amount and reinstall the bolts.
NOTE: Offsetting may require the hydraulic fittings
on the main frame and hydraulic pump be loosened,
rotated, and retightened to ensure the hydraulic hoses
have adequate clearance to moving components.
