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 (STEPÿ1)
and the rear roller leveled to the reel (STEP 2), the cut-
ting 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 en-
tire 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 roll-
er jam nuts and turning each front roller adjustment knob
the same number of turns and in the same direction as
the first unit.
Height–of–Cut Adjustment (Fixed Cutting Unit)
1. Adjust reel to bedknife contact.
2. Loosen nuts securing skids or front roller and raise to
highest position.
3. Loosen jam nuts securing rear roller. Lower roller be-
yond desired height–of–cut (assures proper bedknife
attitude).
4. Lower cutting unit onto a flat surface, such as a 1” x
20” x 30” piece of plywood. Shut off engine and remove
the key.
5. Insert piece of bar stock (Fig. 11) 25”–28” (70 cm) long
with thickness equal to desired height–of–cut, under en-
tire length of the reel, next to bedknife.
6. Adjust rear roller adjustment knobs and jam nuts until
full length of the rear roller contacts the flat surface and
the full length of the reel (not bedknife) contacts the bar
stock. Tighten rear roller knobs and jam nuts.

Adjusting Skids and Front Roller (Fixed Head Cutting Unit)
After skid kit or front rollers are installed (installation
instructions are included with each option) make the fol-
lowing adjustments to prevent them from pushing down
uncut grass or scalping on undulating terrain:
1. Lock each cutting unit in the fixed position (Refer to
Cutting Unit Orientation, Fig. 15. Set the reel to bedknife
adjustment and height–of–cut adjustment.
2. Position the cutting units on a flat, level surface (a 1”
inch (25 mm) thick piece of plywood is ideal).
3. Skids and front rollers used to prevent scalping should
not ride on the ground. Adjust each skid or front roller so
it is 1/8 – 1/4 in. (3 – 6 mm) or higher above the level sur-
face. Allow greater clearance at the higher height–of–
cut settings.
4. Proper adjustment is achieved when the cutting unit
does not scalp the grass in normal mowing conditions
and yet is set high enough not to mar the turf and create
undue wear on the skids or rollers.
NOTE: Skids are used only with the cutting unit in the
fixed position. Front rollers may be used with the cutting
unit in either the fixed or floating position.
