At what bale count roller bearings starts to go? Should i worry about the rollers if it's done 15000? is there a automatic greasing on these ? I can see a oil tank on it for the chains.37000 is nothing for these. I run a 220 profi with around 80000 on. She mostly does around 3000 - 40000 a year with very few issues. Also got a 220 farmer with 35000 ish on doing around 1500 a year again good simple machine.
