SCAG SELF-ADJUSTING IDLER SYSTEMS
All
of the belt systems on the Tiger family of mowers are self-adjusting. They
constantly provide the correct amount of belt tension, eliminating this maintenance
step entirely. The spring-loaded idler arms use sealed bearings that do not
require greasing. These systems are engineered for long, reliable life while
saving you maintenance time. All the belts used on all Scag mowers are constructed with Kevlar cords for extra strength, minimal stretch and increased life. Cheaper belts use polyester cording that is not as strong, and continually stretches throughout the life of the belt.
