We just purchased a 9610 combine and are needing to match this up to a corn head and we are debating between 8RN and 12RN. Normal yields are in 150b/ac range and I like the idea of driving slower and keep the combine full. Will a 9610 handle it? It has PRWD with 520/60*26 tires on the rear 20.8*38 duals on the drive. Thanks for help. Paul

I have seen several on 9600's-so you should be fine. 12 row will cost a fair amount more than 8-row if you are getting a newer head.

She'll handle er no prob

Thanks for replies; I see Dano,you are 9600 operator;do you have a 12R on your combine? If so do you have any modifications on it to help with the 12row?

 

[dano]

No we have an 8R but I understand you pretty much need duals and rear weights for 12R 4wd diffenatly helps too. We have an 8R cause for the expense and awkwardness a 12R just doesn't make sense for us.

I like the idea of a 12rn on a 9610, especially for 150 or bushel corn. With an 8rn on it with that corn you could practically put the hydro lever all the way ahead in 2nd gear if you wanted to. (At lesat I've done that with ours before!)
However, as far as I know there were extras for the 9600/10's equipped for a 12rn. I think the final drives were planatery and the feederhouse lift cylinders we considerably larger, I do not know if the hyd. pump was any different. If yours is not equipped for a 12 row, it probably will not lift it. Perhaps you could check a salvage yard for the things you need.

Yes jd,I have been researching this a bit and you are right on about the extras for the combine. I have not found anything about a larger hyd. pump,but defenitely need the 60mm lift cyl,they are available from Lankota. I don't think we will change final drives unless I can find someplace to swap them.

IME, I would avoid a 12 row corn head. Especially don't put chopping knives on it. I have a 9650 with an 8 row with JD knife rolls. It pulls harder than the feeder house drive can comfortably handle. I added the oil pump and cooler to the feeder house reverser gear box and that helped a lot. But the box gets hot and then when you shut it down, the belt may melt just enough to stick to the sheaves. When you start again, it tears a few small pieces of belt off.

If you take the feeder house moving sheave off, you will discover it is driven by only 1 small key. This key will hammer out the keyway on the moving sheave. This prevents the moving sheave from rotating on the cams that provide the extra torque transmission for hard pulling.

Stick with the 8.

Combines with factory planetary drives came with a lager hydro drive system, bigger hyd pump and larger lift cylinders. When you look at the hydraulic pumps on jdparts for a 9610, the screen says "With planetary drive" on one of the pages.

That sounds like a lot of stuff to swithch out; I guess the planetary drive must take more power to drive if they put a bigger hydro on it. Would the planetary setup be a lot stronger to standup to the weight of the 12row cornhead, or is there some other reasons for using that?

 

[jd9600guru]

I don't know if it would be cost effective for you to do all that swapping, if you are dead set on running a 12 row, I would see if what you have can handle it before you upgrade any parts. The hydraulic pump/bigger lift cyl's may be all you want to change if it has trouble lifting it. The hydro system and finals would cost alot and may not even be needed, to add to that I think the tranny is different for planetary combines since they have to turn more to get the same output speed.

Guru;I think we probably will try it as it is. I think it shoud be alright, the head we looking at is a 1243 converted to poly snouts, I am pretty sure that head would have been used on a 8820 so it shoul work on a 9610.
