Greensmaster Flex 21 Traction and Reel Drive System (Rev. C)Page 4 – 15
Traction Drive Belt Replacement
The traction drive system on the Flex 21 uses a positive
drive belt on both sides of the traction drum. Belt re-
placement on either side requires the same procedure.
Removal
1. Park mower on a level surface. Make sure engine is
OFF. Remove high tension lead from the spark plug.
2. Remove transport wheels if attached (see Wheels in
the Service and Repairs section of Chapter 6 – Chassis
and Controls).
3. Remove cap screw, flat washer, belt cover, spacer
(under cover), and flange nut (backside of side plate:
Fig. 23) to expose the traction drive belt.
4. Loosen idler bracket cap screw on back of side plate
(Fig. 23). Pivot the idler pulley away from the drive belt
to loosen belt tension (Fig. 22).
5. Remove traction drive belt from both pulleys.
