ADJUSTING CUTTING UNIT
Specifications
Height-of-Cut: The cutting height is adjusted on rear
roller by two vertical screws and held by two locking
capscrews. Bench height-of-cut range is 2.4mm to
l9mm. Effective height of cut will vary depending on
turf conditions and bedknife.
Reel Construction: Reels are 13cm in diameter,
53.3 cm in length. High-carbon steel blades are welded
to 5 stamped-steel spiders. and heat treated to RC 42-
48 hardness. The reel is ground for diameter, concen-
tricity. and back grind.
Reel Bearings: Two double-row ball bearings, 30
mm I.D., press fit onto the reel shaft. The inverted seal
is pressed onto the reel shaft. Bearing side load is
maintained by a 3 1/2 turn wave washer, with no
adjusting nut.
Reel Drive: The reel shaft is a 1.375 inch diameter
tube with drive inserts permanently pressed in both
ends. A replaceable floating coupler with an internal
eight-tooth spline is factory installed on the right end,
and held in place by a snap ring. The floating coupler
may be moved to the other end when the cutting unit
is used on the tractor's front right position.
Frame Construction: A single top tube is welded to
two side plates. A bolt-in cross rod acts to set the front
frame width and stiffen the assembly. The lift straps
have a replaceable roller that may be moved to change
transport height.
Bedknife: Replaceable, 13-screw, single-edged, high
carbon steel bedknife austempered to RC 48-55, fas-
tened to a machined cast iron bedbar. Tournament bed-
knife is standard.
Bedknife Adjustment: A single control screw has
detents corresponding to .018 mm bedknife movement

for each indexed position. A linear adjustment on the
bedbar left end allows leveling of the bedknife to the
reel blades. A centered lever arm regulates the knife-
to-reel contact with two rubber bushings acting as piv-
ots.
Front Roller: The standard front roller is a 6.4 cm
diameter Weihle. The right bracket has an eccentric
shoulder bolt to provide leveling. A second eccentric
may be added to the left bracket for increased leveling
range. The roller has a through shaft with greaseable
ball bearings.
Rear Roller: The standard rear roller is a 5.2 cm
diameter smooth roller. It has a through shaft with
greaseable ball bearings.
Front Shield: A snap-in shield covers the lower front
of the reel. The shield helps improve grass throwing
into the basket and prevents the basket sealing flap
from being damaged by the reel.
Counterbalance Weight: The left end of the cutting
unit has a weight with a spin flange like the reel
motors for easy installation. The weight seals the bear-
ing area and balances the reel motor's weight during
cutting.
