Used Gleaner Combine Parts vs OEM and Aftermarket Parts
Used gleaner combine parts are previously installed parts taken from another machine, sometimes called salvage parts. OEM parts are genuine AGCO components sold for your combine, and aftermarket parts are made by independent manufacturers to do the same job. Your choice depends on the part's role in the machine, what you can verify about its condition and coverage, and how a delay would affect your harvest. In every case, confirm the part number against your combine's model and serial number before you order.
The three categories differ in who made the part and what you can verify about it. As an authorized Gleaner dealer, Bison Machinery supplies genuine AGCO Gleaner combine parts, such as bearings, belts, chains, hydraulic pumps and cleaning system components. That page is a useful reference point when you want to see what a factory part covers before comparing other options.
Key Takeaways
Bison Machinery supplies genuine AGCO parts for Gleaner combines and headers. Call Jamestown at (701) 252-7030 to confirm your model.
Before you buy a non-genuine or used part, ask the seller about coverage, return policy and part-number matching.
Always match the part number to your model, serial number and parts diagram.
Weigh part price, installation labor and possible idle hours together, not price alone.
For a used part, confirm its part number, serial-range fitment, and any inspection information or coverage the seller provides.
What Is the Difference Between OEM, Aftermarket and Used Gleaner Parts?
OEM Gleaner Parts
OEM Gleaner parts are genuine AGCO parts. Bison Machinery supplies them for Gleaner combines and headers, and its technicians use the same parts. Confirm the part number against your parts diagram before ordering, and ask the parts counter about any applicable coverage.
Aftermarket Gleaner Parts
Aftermarket Gleaner parts are built by independent suppliers rather than AGCO. Before buying, verify that the supplier identifies a match for your model and serial number, and ask what documentation and coverage come with the part.
Used and Rebuilt Gleaner Parts
A used or salvage part comes from another machine, so its prior use and remaining service life may be less certain than those of a new part. Ask the seller for inspection details to help assess its condition. A rebuilt part has been repaired or reconditioned by a rebuilder. If you are considering either, ask what was inspected, repaired or replaced, and confirm the maker and part number before buying.

How to Choose the Right Part
Start with what the part does. If a failure would stop the combine, compare the available parts carefully, including fitment confirmation, coverage, installation labor and the effect of a delay on your harvest schedule. For any replacement part, confirm the supplier's part-number match to your machine before ordering.
When Do Used or Salvage Parts Make Sense?
For a used part, first match its part number to your model, serial number and parts diagram, then confirm that number with a parts counter before ordering. Ask the seller about price, condition details and any coverage while you still have time to consider other options.
Also think about the part's role in the machine and what an unexpected repair would cost mid-season. If you are already weighing total cost on an aging machine, our guide to buying used heavy equipment smartly covers the same tradeoff at the whole-machine level.
Genuine AGCO Part Categories Bison Machinery Lists
Bison Machinery lists genuine AGCO parts across the groups below.
Bearings, Belts and Chains
Bison Machinery offers bearings, V-belts, poly-rib belts and roller chains for Gleaner combines and headers. Belts, chains and bearings are worth checking before harvest, and having their part numbers written down can speed up a lookup.
Drives and Hydraulics
Hydraulic pumps, motors, cylinders, hoses and variable-speed drive components are listed for Gleaner models.
Engine and Electrical
Bison Machinery lists filters, belts, starters, alternators, DEF sensors and harnesses for Gleaner S9 and T Series engines. The serial number matters when a listing identifies a serial range or when the model alone is not enough, so start from the serial plate rather than a photo of the old part.
How Do You Check a Used Combine Part?
Start with the numbers, not the hardware. Bison's parts lookup process begins at the model and serial plate on the combine. You use those numbers to open the correct parts diagram, read the part number off the diagram, then confirm that number with a parts counter before ordering.
Apply the same step to a used part. Find the number on the part, match it to the callout on your diagram, and confirm the serial range before you commit. A parts diagram is an exploded drawing of one assembly, such as the rotor or feeder house, with a callout number for each piece and a matching list of part numbers, descriptions and quantities.
Photograph the part and the serial plate so you have both on hand. If a repair turns out bigger than planned, the Jamestown service department lists technical support and parts lookup among its services.
Which Option Costs Less Over a Full Harvest?
Purchase price is only one line in the math. The fuller comparison is the part price, the labor to install it, and the value of any hours the combine sits still. Those numbers are specific to your acres, crop and schedule, so run the comparison for your own operation rather than relying on a general rule.
Plan ahead where you can. Write your model, serial number and year on a card in the cab and keep the same photo on your phone. Then check belts, chains, concaves, sieves, knives and bearings, and look up their part numbers while you still have time to compare options and place an order.
FAQs
