Bedknife attitude Set attitude (angle) as recommended.
See Leveling Front Roller to Reel and Attitude
Adjustments.
Rear roller adjustment Check and adjust as necessary. The rear roller must
be leveled so it is parallel with the reel for proper
height−of−cut setting.
See Height−of−Cut Adjustment.
Height−of−cut “Effective” or actual height−of−cut depends on the
cutting unit weight and turf conditions. Effective
height−of−cut will be different from the bench set
height−of−cut.
See Height−of−Cut Adjustment.
Proper bedknife selection for height−of−cut desired If the bedknife is too thick for effective height−of−cut,
poor quality of cut will result.
Stability of bedbar Make sure bedbar pivot bolts are seated securely.
Check condition of the bushings in the side plates.
See Bedbar Removal and Installation.
Number of reel blades Use correct number of blades for clip frequency and
optimum height−of−cut range.
Cutting unit alignment and pull frame ground following Check pull frames and lift arms for damage, binding, or
bushing wear. Repair if necessary.
Roller condition Make sure rollers rotate freely. Grease roller as
recommended and repair bearings as necessary.
See Roller Bearing Replacement in Service and
Repairs section.
Reel speed All reels must rotate at the same speed (within 100
rpm). All cutting units must have equal bedknife to reel,
front roller to reel, attitude, and height−of−cut
adjustments. Check reel speed setting if a
backlap/variable reel speed kit is installed.
