Hydrostatic. Less than 500 acres on rebuilt clean grain auger gearbox and new tailings return chain and conveyor housing tin and both cylinder drive belts. Have a new set of rasp bars to go with. Hour meter no longer works but it did when I bought the machine so I know it has about 5,200 hours. Used it to combine 35 acres on July 22, 2023 and it ran great. Add is for combine only, pickup head not included.
