Genuine or Replacement

Because the Woods RM306 mower is no longer manufactured, the belt may be a replacement part rather than a genuine Woods part. Although the belt isn't manufactured by Woods, it works similar to the original part. An authorized Woods equipment dealer can suggest the best replacement belt for your mower.



The belt on a RM306 mower drives the mechanisms to operate the rotary cutting blades. The long belt wraps around at least seven mechanisms and requires a half twist and a full twist at two locations in the belt routing. Woods suggests adjusting the new belt every half hour during the first two hours of use then adjusting the belt every eight hours thereafter.
