Rear Roller Height Adjustment
The rear roller of the Flex 21 has two height positions.
Rear roller height should be matched to the height–of–
cut setting. The upper roller position (shown in Fig. 16)
should be used for height–of–cut range .062 to .156 inch
(1.6 to 4 mm). The lower position should be used for
height–of–cut range .125 to .296 inch (3.2 to 7.5 mm).
1. Remove rear roller (see Roller Removal).
2. Loosen locknuts that secure roller brackets to mower
side plates.
3. Move eccentric bolt (mower right side) and shoulder
bolt (mower left side) to allow desired position of roller.
4. Re–install rear roller to brackets (see Roller Installa-
tion).
5. Level rear roller (see Leveling Rear Roller). Tighten
locknuts.
