g) Adjust anti-scalp rollers for Normal Operating Conditions. Stop engine, wait
for all moving parts to stop, and remove key. Place rollers in one of the
positions shown in Figure 11. Rollers will maintain 3/4 in. (19 mm)
clearance to the ground to minimize gouging and roller wear or damage.
For Maximum Deck Flotation, place rollers one hole position lower.
Rollers should maintain 1/4 in. (6.4 mm) minimum clearance to ground. Do
Not adjust rollers to support the deck. Be sure bolt is tightened properly or
loss of anti-scalp roller may result.
