How many do you wantIJI see 6 or 7 for sale in the Ontario Farmer, from $1000 to $ 5000 CAN. look for worn shafts and couplers. If you can turn the main drive shafts more than a 1_4 turn before the snapping rolls move, inspect further. It could just be worn chain couplers, but likley is worn splines and shaft couplers--easy to see if you crawl under and watch as you turn the main shaft--but expensive to replace. Also make sure the double bevel gear that drives the rolls has less than 1_8 inch lateral movement on its shaft--if more,then it and_or the shaft is wore also big$$$ Ben.
