OPERATION 6
6.6 REEL MOTOR MOUNTING________________________________________________
1. The cutting head motor mounting adapter, coupling and
hardware are shipped in the step located above the left
front wheel. Install a 1.49" i.d. x 07" (38mm x 1.7mm) O-
ring on the male side of motor adapter plate and a 1.99"
i.d. x.07” (50mm x 1.7mm) O-ring on the reel motor
mount face.
2. Remove and discard screws holding the shipping cover
to cutting head (retain the shipping cover to protect the
bearings whenever the motor is removed from the
cutting head).
3. Install coupler (A) on cutting head shaft.
4. Install motor adapter plate (B) positioning the male face
and O-ring (C) toward the cutting head.
5. Install two (2) 5/16-18 x 1 1/2” screws (with washer and
lock washer) loosely into the mounting holes.
6. Align the splines on the motor shaft with the coupler (A)
and slide the motor into place rotating approximately
45° away from the mounting screws. With motor face
against adapter plate (B), rotate the motor mounting
flange into place engaging the screws into the motor
mounting flange slots. Tighten screws to 18ft/lbs
(24 Nm).
7. Add lithium based lubricant to the bearing housings at BOTH ends of the reels bearings at both ends are par-
tially packed with lubricant at the factory, but additional lubricant is required once assembled. Use a grease
gun to add lubricant until it starts to escape from the fittings. Wipe off any excess lubricant.
NOTICE
Check to MAKE SURE when the cutting heads are lowered to the turf, they must contact the turf evenly
across the entire length of the cutting head. If the front cutting heads contact the level surface unevenly,
refer to the adjustment section in the parts and maintenance manual.
