Alternater after alternater,broken spindles on rear,feeder chains constantly jumping cog, shearing bolts on cylinder gearbox,cage sweep plugging on sidehills, feeder housing plugging(no reverser),cables in concave breaking, trap door blowing open on minor slugs,chain wearing down on accelerator rolls every third day, seperater clutches,oddball belts that can't be bought at local wholesaler, running hot all the time even though clean,poor air condioning,oil leaks since day 1, and on and on.
