Lots of new parts the last few years. Most of the bearings are new. New twine pump. Half the belts are new the other half are good used ones I put on. Tires, wheel bearings new, Gate cylinders rebuilt last fall. I believe it has every option you could get on a 535. Has the variable core valve for easier bale starting. Automatic chain oiler that Ive never used, has hydraulic raise for the pick up but the cylinder is broken still can raise and lower manually with the crank. Have some extra bearings and pickup teeth to go with also. Definitely not the latest and greatest but works well, makes decent consistent bales. I mainly used net wrap. Has monitor that works as it should, everything is mechanical on these balers and dont need the monitor to make a bale.
