I used to run an 8560 was a good machine, but a little underpowered. Check out flighting on front of rotor and all structure around rotor, these were weak points and will bend and stretch for hard thresh crops. Rear axle spindles were also weak so check to see if they are updated. Simple maintinance and less belts,chains and gearboxes than the TR also cpapacity is comparable to a TR95. email if you would like more info. I also have a corn chaffer and air foil chaffer for 8560 will sell for low price.
