3. Make final height–of–cut adjustment with gauge
bar.
A. Raise cutting units and lock in the transport posi-
tion. Shut off the engine and remove the key from
the ignition switch.
B. Use gauge bar (Toro Part No. 59–7900) to set fi-
nal height–of–cut by adjusting the front roller only.
C. Loosen gauge bar jam nut and adjust screw to
set dimension between underside of screw head
and gauge bar for desired height–of–cut (Fig. 9).
Tighten jam nut to secure the adjustment. Hook
screw head over cutting edge of the bedknife and
position bar against bottom of front roller (Fig. 10).
D. Loosen front roller nuts, and adjust both ends of
the front roller until it contacts the gauge bar at both
ends. With the gauge bar held firmly against the bot-
tom of the rollers, adjust front roller so the screw
head slips just over the lip of the bedknife (Fig. 10).
Tighten front roller nuts.
IMPORTANT:When set properly, the front and rear
rollers will contact the gauge bar and the screw
head will be snug over bedknife cutting edge when
checked at both ends of the reel.
E. Loosen lockout pin so cutting unit can float freely
(Fig. 6).

Quick Method For Changing Height–of–Cut After Initial Set Up of a Floating Cutting Unit
If the reel to bedknife adjustment has been set in STEP
1 of Height–of–Cut Adjustment (Floating Cutting Unit)
and the rear roller leveled to the reel in STEP 2 of
Height–of–Cut Adjustment (Floating Cutting Unit), the
cutting unit may be quickly changed from one height–
of–cut to another by using the gauge bar (Part
#59–7900) and adjusting the front roller only. In many
cases, an entire machine can be done quickly by using
the gauge bar to set the front roller of one cutting unit.
The remaining cutting units can then be set by loosening
their front roller jam nuts and turning each front roller ad-
justment knob the same number of turns and in the
same direction as the first unit.
