What the 839 Grain Cart is used for
The 839 is used to receive combine grain without stopping the harvesting pass, then transport the load to a semi or truck. Its unloading auger is used at the headland to top off trailers with controlled grain flow. Scale equipment, if fitted, can record cart loads and support truck loading.
Why the Parker 839 Grain Cart stands out
The side-fold corner auger can provide good unloading reach while keeping the cart compact in transport. A swivel hitch, observation ladder, viewing windows, and lighting support everyday hookup and field operation. The single-axle design uses a 120-inch rigid axle.
Buying a used Parker 839 Grain Cart
Inspect auger flighting, the folding pivot and cylinder, gearbox, PTO shaft, shields, and the hydraulic flow-control system. Check the 30.5 x 32 tires, hubs, axle, tank floor, seams, and hitch for damage or excessive wear. Test the scale system under a known load if the cart has one.
