Adjustment Summary and Check List
DETAILED ADJUSTMENT INSTRUCTIONS FOLLOW
THIS SUMMARY AND CHECK LIST. Study this infor-
mation and refer to it often to get maximum life and
performance from the cutting units.
Daily Performance Checks
NOTE: It is not necessary to remove cutting units from
traction unit to perform these daily checks. It is recom-
mended that mowers be washed after each use. Always
remove key from ignition switch when working on the
machine.
1. Purge water and debris from al
l bearings by greasing
them. Use No. 2 multi-purpose lithium base grease.
2. Visually check for sharp reel and bedknife.
• Remove burrs, nicks, and rounded edges.
3. Lower cutting units to the ground (setting on both
roll
ers). Remove reel motor and rotate the reel back-
wards by hand. Light contact between the bedknife and
reel should be felt and heard.
• It should be possible to pinch newspaper when
i
nserted from the front, and cut paper when
inserted at a right angle (along entire length
of bedknife).
• It should be possible to cut paper with minimum
bedkni
fe to reel contact. Should excessive reel
drag be evident you must backlap or grind
the cutting unit.
• No contact will dull the cutting edges.
• Excessive contact accel
erates wear, and quality
of cut may be adversely affected.
4. Check reel speed controls. If necessary, adjust reel
speed to settings shown on REEL SPEED SETTINGS
graph for number of reel blades (5 or 8) and desired
ground speed (see Operator’s Manual and decal on
machine under seat plate).
NOTE: Reel speed settings may require “
fine tuning”
from initial adjustment for optimum cutting performance.
Weekly Checks
1. Check reel bearing adjustment a
nd bearing condition.
2. Make sure bed bar pivot bolts are securely seated
(
maximum 40 ft-lb.).
3. Using a gauge bar, verify correct height of cut setting
and adjust as necessary.
4. Check lift arm down pressure springs. Make sure all
springs have same down pressure setting.
Monthly Adjustments
NOTE: Remove cutting unit from traction unit before
doing these checks and adjustments (See Cutting Unit
Removal and Installation in the Repairs section of this
chapter.)
1. Visually check f
or sharp reel and bedknife. Backlap
or grind reel and bedknife if necessary.
2. Adjust front roller.
3. Adjust bedknife to reel contact.
4. Using a gauge bar, set the height of cut adjustment.
5. Adjust rear roller
scraper (if equipped) to be 1/32 in.
from roller.
6. Check grass shield adjustment.
7. Set top bar adjustment.
• 0.060 in. from reel - normal.
Special Notes
1. A “rifled” reel and/or bedknife must b
e corrected by
grinding.
2. If reel bearings will not hold adjustment during opera-
tion, loosen adjustment nut, tap on head of bolt at end
of reel shaft with a small hammer until end play of reel
shaft can be felt, tighten reel shaft
spline nut
to a torque
of 40 to 60 ft-lb, then adjust reel bearings.
