Mich, Those are for the Ranger Auto drive. David has the Rancher Auto drive, Very different machine. the parts manual is in the manuals section of the ride on forum, you will need a subscription though. To my knowledge there is only 1 idler, which is the clutch idler on the engine belt. the belt that goes around the clutch pulleys only has the big idler at the top, which has a replaceable bearing, and a double pulley assembly that runs on normal bearings in between.
