The Quick Change Hitch from Tebben is a retrofit, universal attachment that mounts directly to the hydraulic loader of any skid-steer. Hydraulic lock-in pins slip easily into place to secure various universal attachments. "The operator doesn't have to climb in and out of the loader to change attachments," Mike Tebben explains. "It's all done right from the cab. And the Quick Change Hitch takes up only 2 1/2 in. between the loader and the attachment." Contact Tebben Enterprises, Dept.

(according to requirements for identity preserved grain) 1 Give the machine a rough cleaning in the field. Unload the grain tank; drop the trap doors; clean off the feederhouse and reel; and clean the ledges in the grain tank. Run the separator and unloading auger a second time. Drop the unloading auger trap door where you can catch the seed in a pail from the grain tank.

2 In the shop, remove and open all remaining traps on return legs and remove housings around the cylinder. Take out the sieves and straw chopper assembly; make sure to open everything around the cylinder and on the bottom of the machine to dislodge seed.

3 Roughly clean the machine with an air hose. Start with major cleaning in the cylinder area; blow out the cylinder cage while running the separator; blow out the straw chopper area with the machine off.

4 Clean the cylinder, concave cages and adjacent areas with high-pressure air with the machine off. Pry out wedged seed in these areas; reattach concaves and run the separator while using high-pressure air; clean the feederhouse by blowing backwards down the feederhouse toward the header; clean the entire header, including platform and sickle guards.

5 Clean the top of the machine in the grain tank and unloading auger; blow seed out of unloading auger while reversing the auger by hand.

6 Reexamine the cylinder and blow out any seed drop from the grain tank; vacuum the auger below the cylinder, then vacuum the augers on the return end grain leg below the sieves.

7 Run the machine to remove the dust and loose seed.

8 Reassemble the parts removed while vacuuming out any additional dislodged seed, while the machine is running. - South Dakota State University
