Height−of−Cut (HOC): Cutting height is adjusted on
the rear roller by two vertical screws and held by two
locking capscrews. Bench HOC range is 3/32 inch
placeable 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.
(2.4mm)
to 1−1/32 inches (26mm). Cutting units will de-
liver differing effective height−of−cuts depending on
their configuration. In fact, effective cutting height may
be influenced by the following factors; turf conditions,
roller profiles, cutting unit attitude, cutting unit accesso-
ries, weight of cutting units and bedknife profile. There-
fore bench setting a cutting unit does not equal the
effective (actual) height of cut you achieve. You need to
determine how to adjust your cutter on the bench to
achieve a comparable height of cut to a cutting unit of a
different configuration, model or brand.
Bedknife Adjustment (Single Point Adjust): A single
control screw has detents corresponding to 0.0007 inch
(0.018
mm) bedknife movement for each indexed posi-
tion. A linear adjustment on the bedbar left end allows
leveling of bedknife to reel blades. A centered lever arm
regulates knife to reel contact with two rubber bushings
acting as pivots.
Reel Construction: Reels are 5 inches (13cm) in diam-
eter, 21 inches (53.3 cm) in length. High carbon steel
blades are welded to 5 stamped steel spiders and heat
treated to RC 48−54 hardness. The reel is ground for di-
ameter, concentricity, and back grind.
Bedknife Adjustment (4−Bolt Adjust): Two opposing
screws on each end of the bed bar are used to level and
regulate bedknife to reel contact.
Front Roller: Standard front roller is a 2.5 inch (6.4 cm)
diameter full radius Wiehle. The right bracket has an ec-
centric shoulder bolt to provide leveling. A second ec-
centric may be added to the left bracket for increased
leveling range. Roller has a through shaft with grease-
able ball bearings.
Reel Bearings: Two double row ball bearings,
(30
mm I.D.) are press fitted onto the reel shaft. An in-
verted seal pressed onto reel shaft. Bearing side load
maintained by a wave washer, no adjusting nut.
Reel Drive: The reel weldment shaft is a 1.375−inch di-
ameter tube with drive inserts permanently pressed in
both ends. A replaceable floating coupler with an inter-
nal 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 front right position.
Rear Roller: Standard rear roller is a 2 inch (5.2 cm) di-
ameter smooth steel roller. Roller has a through shaft
with greaseable ball bearings.
Counterbalance Weight: The end of cutting unit oppo-
site the reel motor has a weight with a spin flange like the
reel motors for easy installation. The weight seals the
bearing area and balances the reel motor’s weight dur-
ing cutting.
Frame Construction: Single top tube is welded to two
sideplates. A bolt−in cross rod acts to set the front frame
width and stiffen the assembly. The lift straps have a re-
