Question:
Just purchased a new DRT900H tiller. Immediately upon engaging it into forward motion (or any), noticed it was making kind of a grinding noise and sounded like it came from the drive unit, then I noticed the cover over the drive belt was vibrating. I ignored it at first then today it happened again, so I took the cover off and discovered that the main belt pulley for the drive unit was rubbing against the belt cover and has almost worn through the exterior of the cover.
Who would I contact to get this replaced? It looks like that the cover should've been made with a little more clearance inside of it.
