We've had no trouble in 4 harvests. Bought the machine and it needed the posi rebuilt so with a new belt it works fine. 2nd goes from 1.7 to 4.0. 3rd goes up to 6mph.Good range for our needs.

In the parts manual it showed 6-7 parts at apx. $450 each. Did you need to replace many of them, or just bearings and bushings. We will be running mainly in dry Texas wheat.

bearings and bushings. it had a leak and the belt was soaked. we also did the variable speed on the cylinder, same thing. i think it's a good system. we're mainly spring wheat with a 24' swath. easily 4 - 4.5 mph(ours is Titan II)
