What the 851 Grain Cart is used for
The 851 receives grain from the combine while harvesting is underway and hauls the load to a waiting truck or semi. Its capacity suits operations that need a smaller cart than a 1,000-bushel class machine. An optional scale can help operators document loads and manage truck filling.
Why the Kinze 851 Grain Cart stands out
The 851 uses a single 20 in corner auger and a remotely adjustable discharge spout. A 1,000 rpm PTO driveline with overrunning and torque-limiting clutch protection powers the unloading system. The compact overall length of about 28 ft 4 in can be useful in smaller fields and tighter farmyards.
Buying a used Kinze 851 Grain Cart
Check auger flighting, the auger tube, cleanout system, gearbox oil, PTO clutch, and all driveline shielding. Inspect tire condition, wheel hardware, hitch, tank floor, and frame for wear or corrosion. Operate the hydraulic functions before purchase and verify any scale system with known weights.
