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 (STEP 1)
and the rear roller leveled to the reel (STEP 2), the
335-D 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 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
hig
hest position.
3. Loosen jam nuts securing rear roller. Lower roller
beyond 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
wi
th thickness equal to desired height-of-cut, under
entire length of the reel, next to bedknife.
6. Adjust rear roller adjustment knobs and jam nuts until
fu
ll 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
following 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
Cut
ting Unit Orientation, Fig. 15. Set the reelto 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
le
vel surface. Allow greater clearance at the higher
height-of-cut settings.
4. Proper adjustment is achieved when the cutting unit
do
es 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.
