Toro Groundsmaster 328-D, Service Manual

Page: 354 / 402

Center Section:
NOTE: Spring tension is only 10 to 15 lbs. on the wing
section, but is 80 to 90 lbs. on the center section,
requiring the use of a threaded rod for adjustments.
1. Loosen nuts securing the spring bracket to the deck.
Loosen the jam nut on the threaded rod.
2. Adjust the spring bracket so that the lip on the spring
bracket just contacts the rubber stop on the idler arm.
Use the threaded rod to make belt adjustments. Tighten
the capscrews and nuts securing the spring bracket in
position and tighten the jam nut on the threaded rod.
3. Be sure all belt guides are in the correct position and
secured to the deck before operating the cutting unit.
IMPORTANT: If there is a gap of more than 3/16 inch
between the rubber stop and the idler arm a belt
adjustment is necessary.
IMPORTANT: Too much tension on the belt will
cause early belt failure.
