I have a 1995 2188. It has tracker, chopper, 4wd, and hopper extension. I have replaced several parts in the last 4,000 acres such as alternator, feederhouse chain and floor, all unloading augers, unloading auger tube, unloading auger elbow (extended wear), clean grain elevator housing and chain, lower clean grain auger, upper sieve, auger bed bearings, shoe drive shaft and bearings, and concaves. I also installed a shoe slow down kit. Tires are good, rears were replaced last season. Condition is good for the age of the machine. What is this machine worth?
