Duals on Oliver 7300

oliverkid · Oct 25, 2023

We have had 5.25 inches of rain since October 5th with little to
no sunshine in between to dry things out. Now a lot of fields are
to the point where just walking across them can be a chore.
Yesterday was the first time since October 4th that beans have
been dry enough to cut and haul in. Took me 7 hours of slogging
through knee deep mud to manage about 8 out of 14 acres in
one field and I have more that are gonna be about the same.
Was thinking of looking for some clamp on duals for the 73 just
wanted to know if anybody had done it before and if the final
drives would be ok. Would follow the obvious rules of half hopper
loads and avoid using the turning brakes.

tom sears in your neck of the woods had a oliver 7300 with duals for sale a while back. thought that was strange

Back in the day we had a 7300 that had duals on it. We didn't use them, but the previous owner had. No issues.

We run duals on our 7300 one fall....no problems except for the climb to get in it without a ladder

I'm no help, but I know what you're going through. I've picked ear corn a total of five days now. Two days last week and three this week. I've been picking with the 1850. After this morning's rain, I'm pretty sure I'll be picking the rest with the 2-105 with the duals on. It's not ideal. I have to set the tongue over a fair distance. I had to do it one other wet year so I know it can be done.

Based on my experience with my first 7300 I would not recommend it if you are running in hilly ground. Mine was purchased used with no axle extensions but with the drive wheels reversed (dished out) for more stability. I popped at least 2 axles on the downhill side. Remember going to Omaha to pick up a new one once. Not fun to jack up the combine in the field to remove the final drive to put the new axle in! If your ground is level you will probably be OK. Made me a believer in axle extensions which my 2nd 7300 had. It also had the Perkins diesel.

Thanks for the replies.

Dont do it. If you do, go ahead and look for axles and couplers before starting. You will replace them.

Might consider finding a set of rice and cane tires for your combine. I have a set on a Ford 642 and another with rear wheel assist and the one with rice and cane tires can get around in the mud almost as well as the one with rear wheel assist.

We had a really nice 7300 at one time, and bought a head from a man that had maybe half a dozen of them. I don't think he ran duals on any of them, but he told me that they didn't have very strong final drives, and that he had broken a good amount. I think he had said a 4 row corn head and mud would break them pretty easily. I don't think I would put duals on, but I'd be ready to go when the weather broke just a little. One year we were struggling to finish up and it would freeze just enough to hold up the 7300 around midnight. I filled the truck every night around midnight for a bit, and finally finished up. We are almost done combining here, just a few acres left and I was actually thinking today that it sure would be neat to have that old 7300 back to finish up.
