b) Adjust anti-scalp rollers for Normal Operating Conditions. Stop engine.
Place rollers in one of the positions shown in Fig 14.
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
roller bolts and nuts are installed with the spring disc washer between
head of bolt and mounting bracket.
Torque to 40-45 ft-lbs., or loss of
roller may result
.
c)
When operating in extremely rough conditions it may be necessary to
position the anti-scalp rollers one or two holes higher than described in
"b" to prevent damage to the rollers and/or bolt failure(See Figure 14).
NOTE:
When anti-scalp rollers are placed in these positions, reduced
deck flotation will result.

the left handle and the left rear corner of the engine deck.

b)
With blade drive engaged, adjust the linkage length by loosening the
locknut on the turnbuckle and adjusting the turnbuckle so that the bolt on
the bellcrank and the indicator arm align with each other within 1/16”.
