95 JD straw chopper

Nathaniel Watts · Dec 9, 2013

I have been giving thought to my worn out chopper now that we are in the off season. It never has done much of a job of spreading the residue. I am planning a new bottom sheet, bearings, knifes, and hammers. I need it to spread more evenly so I can get a better stand of wheat notilling behind beans. I would like info on how to replace the chain drive with a belt as I have heard before a few times here. Maybe a few thoughts on increasing the speed as well. Any other thoughts are welcome.

I found with some tinkering that it all depends on the angle of the bottom adjustable pan and angle of the fins as well as how far you have the fins adjusted. I would like to make a longer and taller set of fins to put on mine to make them more aggressive like the newer combines have. I cant complain much about it but I would like it to spread the hole 16 feet, If it had a 13ft head it would be about right I guess. It just takes a lot of tinkering to get it like you want it.

I have herd of changing the chopper drive to a belt but I have never seen one changed over. A belt drive I think would be hard to keep it tight enough not to slip, And how would you keep it tight enough without putting to much pressure on that main shaft and bearing? That's why mother Deere made it chain drive even if its a pain in the butt to deal with and maintain. I think if you rebuild chopper and tinker with the fins a bit I think you will be happy with it. This picture is last years 70 bu bean crop that were 4+feet tall in 20 inch rows. Bandit

Belt driven straw choppers aren't a problem. JI Case combines and many others have belt driven choppers.

We have the same issue with the 45. It has new stationary knives and the flails are not bad at all. I, like you, have pondered speeding it up a bit by putting a slightly smaller sprocket on the countershaft. I need to do some speed calculating first. If if you figure out the magic fix please share.

I had a 95 late model corn special and the chopper was belt driven, it spread as well as 4400 and 6600 did picking soybeans. I tried what the operators manual said not to and that was left it on picking corn, the cobs beat the bottom out soon. But on soybean it did great. I had an intermediate feeder house and ran a 454 row crop head for soybeans and grain sorghum. Just my experience. Look at the parts book on John Deere website for the belt and pulleys.

I'm not even getting 13' in the heavy stems we had this year. It was bad enough in one field I had to get the tedder out.

On these JD combines like the 55 95 and 105 they have a chain off the main shaft that goes down and back to drive the chopper belt. The big problem with making it a belt and not a chain is ware to mount an idler tension pulley and the 3 belts you would have to take off to put that belt on. And the 2nd would be the constant pressure put on a shaft ware the pulley is about a foot from the bearing. With the chain drive you can drop the chopper off and be back running in about 10 mins, 4 bolts and 1 master link and its done. I really think that Deere got it right on this one for the way it is made. Even if its a pain to maintain. Bandit

There was an aftermarket company that made a straw chopper drive for those old girls, they were quite popular and I have seen several, the pulley system was usually painted yellow and a long two sided V-belt ran it. Helped quiet the machine down and was quite reliable. We ran one with this belt and a Norwich Belt Drive that eliminated the double 60 cylinder drive chain and that thing was quieter than the 7720 we replaced it with. My problem is I need the belt for the straw chopper drive and I can't recall the company who made that setup. Probably long gone I know but a name would give me a place to start.
