17.5BELT REPLACEMENT
When replacing one belt the other should be inspected for wear and replaced if worn. It is good practice to change both belts when either is worn beyond use. Use only original equipment belts for replacement. Billy Goat uses only premium quality, kevlar corded and coated belts in your unit.
Substitute belts do not meet the design and performance requirements for your unit , and will greatly reduce machine performance and belt life.
