Used Combine Harvester Access Hatch

Exterior Access Hatch: the Most Exposed

On a combine harvester, you distinguish between interior hatches, accessible after removing a panel, and the exterior access hatch, opened from the ground or platform several times a day during the season. This hatch bears the brunt of site impact, road vibrations, and hinge wear. The most frequently used is located at the base of the grain elevator, where unblocking takes place after a jam. Others close the cleaning tank or the shakers at the rear of the machine. On older combine harvesters, the original hatch is often no longer manufactured new.

Custom or Original Access Hatch?

On a combine harvester, a custom-cut hatch made in a workshop can be a temporary fix, but it rarely meets the manufacturer's technical specifications: folding, reinforcements, seal, and locking mechanism. On a grain elevator, a poorly closing hatch leaks grain at every chain rotation. A used original hatch fits the factory mounts without drilling or modification and restores the designed seal. On John Deere as well as New Holland, original access hatches are often the simplest solution to properly seal a combine harvester's tank.

Access Hatch: Dimensions and Exact Reference

• No standard size: each manufacturer sets dimensions depending on the hatch location.
• Grain elevator: the hatch matches the width of the chute, which varies between generations.
• Exact reference: the only reliable criterion for ordering.
• Photo: interior and exterior views, showing fasteners.
• Machine: brand, model, year, and serial number of the combine harvester.

Hopper Hatch and Elevator Base: Identifying a Leak

A grain leak is rarely visible from the cab. When the combine is stopped, look for a small pile of grain on the ground near the base of the grain elevator or a regular trail behind the machine in operation. Near the hopper, a poorly fitting access hatch allows grain to escape during transport to the cart. In both cases, the seal, hinge, or latch is usually to blame; rarely just the sheet metal. On the grain elevator, a dented hatch can also contact the chain pallets and accelerate their wear.

Checking an Access Hatch Before Harvest

• Sheet metal: no bends or dents, especially around fasteners.
• Seal: flexible, continuous, without gaps in corners.
• Hinge: no play, with a freely rotating pin.
• Latch: remains closed despite vibrations during transport on the road.
• Grain elevator base: after unblocking, close, run for a few minutes and check for any falling grain.

Combine Harvester Dismantling Since 1945

TMC Bejenne has been dismantling agricultural machinery since 1945 on a 11-hectare site in Naintré. Each combine harvester is dismantled by our specialized technicians, from the grain elevator to the rear of the machine. Each access hatch, whether for the grain elevator or tank, is cleaned and inspected: sheet metal, hinge, seal, and locking mechanism. Deformed parts are discarded. Our advisors confirm compatibility at 05 86 24 00 26 and ship throughout France.
