Looking at 7230 with no chopper. Stopped in at my local case dealer to find out if there is a kit a person can install, couldn't find anything. One of their 30 year veteran mechanics happened by, asked him if he has ever installed one, nope and didn't think anyone at the dealership had ever installed one. Maybe this is a deal breaker? Any after market ones? How much labor to install? Then need processor behind it ( think that's what it's called) to spread straw. Maybe just find a machine with the equipment I need? Found a thread that was talking that choppers actually slow productivity of the machine, to close to rotor and can't feed it through fast enough. Producer was talking about bolting a New Holland chopper on back and that Case is working on a external one?

Does it have a dual-speed pulley with clutch that drives the beater? Or is it just a large, single pulley on it? I assume also there are no stationary teeth installed. If you were to install a chopper (see below), you'd need the dual speed stuff and also to install the stationary teeth.

The chopper has always been a weak spot on these machines and a bad design. Mainly the shaft within a shaft design. The inner shaft turns slowly on the big pulley, and the chopper itself spins around that usually coupled to the small fast pulley. The big bearings have been known to run hot and fail when in high speed mode. Also there's a lot of side force on these bearings the way things are mounted which doesn't help (especially the inner shaft). But I've never felt the chopper slowed productivity. It sure takes a lot of power when the straw is tough, but a MAV would also consume a lot of power.

For various reasons (including sheered the clutch teeth), I've been into the big chopper bearings several times. Takes a couple of hours to remove everything and get to where you could replace the bearings. Once you're at that stage, it's not much more work to unbolt the side plate that holds the bearings and allow replacing (or installing) the chopper. So it is doable.

Case offers the MAV as a factory-installed option on the 50 series now.

Thanks torriem have not had a chance to look at machine yet, it's a 2013. So your saying if it has the dual speed pulley I can install the rest with Case parts? Looked at the price of the MAV holy sh** that's almost a quarter of the price of the combine.

I heard just the other day that MAV for CIH is pretty costly.
But here is the kicker when those case chopper hammers go through the oil pan MAV will be a cheap deal.

Yes it is possible but looking over the parts list, it will be complicated. Unfortunately my reading of the parts manual shows that the beater only has the one pulley drive on it (large pulley), and no shaft within a shaft. So you'll have to replace the entire drive system. It's not impossible but would take a few days and require a bunch of expensive parts.

Here's the parts diagrams of the things you'd have to replace/install:

https://partstore.caseih.com/us/parts-search.html#epc::mr49710ar1138601 (I recommend this manual shifter over the "remote shift")

Oddly enough the parts list shows the beater as standard and the chopper is optional. I guess corn and bean guys don't need the chopper?

Neighbor had that happen twice. Stuck into the bottom of the oilpan.

They switched the chopper out.

torriem, found the kit it's 47846379 for $12,455.00 through Case but no one has one or knows anything about it. Having my parts guy in Havre call Case and find out. Also Larry from Worthington Tractor Parts Sioux Falls contacted me, they sell the Redekop MAV ( 220-212 ) model for $22,710, bit pricey. He says I can drive it off the existing beater drive. Sure wished I could find somebody who has done this. Looks like it should be simple add on. Been at this farming game for 38 years so know how simple things can turn into a cluster F. Let me know what you find out. Your probably close enough and need a winter project. I'm only 60 miles from Milk River.

I've lost chopper blades and damaged the tin but I've never had one hit the oil pan. I don't know of anyone who has either. And there are a lot of these machines in my area. Statistically it's unlikely to happen to you. It's a pretty rare thing, but sucks when it does happens.

If it were me I'd keep looking for a machine that has the chopper. There are no machines up here that are sold without a chopper and there are a quite a few sitting on dealer lots around here. Might want to look north? Or are you trying to trade?

There’s prob no conversion kits in the US because all the OZZIES are taking them. In the last 4-5 yrs there’s been a massive fad of converting beater machines to choppers via the kit or bundle. The excessive price of the MAV is also making people go for the OEM chopper instead of the MAV.

I have an internal chopper I want to give away for a beater.............shame your more than a day’s drive away.

I don't think the neighbor I talked to went thru the oil pan think his was the fuel tank.
Another fellow a little way away 30 miles or so his went into the engine oil pan.
Anyways its a cluster F#%@ poor design period.
First neighbor bought different CIH machines and put MAV on both.
He is extremely happy with his MAV.
I have MAV on my MF combine and it does a good job no complaints.

torriem - been looking north not a big selection of class 7's mostly 8's and 9's. Everything also comes with pickup for extra 5-10 grand which I have no need for and not much resale value down here. But yea your right, should just find one with chopper. Didn't know chopper would be deal breaker. Combine has been on the lot down here for over a year. They've lowered the price three times now it's down to around 100 grand. Adding a MAV for almost 1/4 the price of the machine just doesn't make sense. My parts guy did get ahold of Case, the kits are on back order 42 weeks out and there's a couple parts for the kit that out farther than that.

Yeah you can find class 7s sometimes (that's what we run). Honestly I don't know why the dealers push 8s and 9s up here so much. They aren't of much benefit in our irrigated crops except to lose grain faster.

The last machine we bought from RME a couple of years ago was a 7240 without any pickups, so sometimes they do sell them without.

Keep an eye on the auctions too.

have you tried any salvage yards? Or put an add out for the chopper and spreaders. I know a few guys that have switched the choppers for beaters then put a MAV on the back because they wanted a better chop and more spread with 45ft headers

Look into burned ones too. Sometimes you can find online auctions for salvage stuff. The one that burned of ours went that way through insurance. Was bought by a private guy that had 3 or 4 other flagships.

Newer class 7s have as much or more power than the first 8010s. I'm really happy with my 7230.

After what I've learned through these threads, I think its best to see if I can get the machine cheap enough to make it economical to put a MAV on. If not move onto something with chopper. Wonder why a MAV for JD is $13,000 and one for Case is $23,000? Anyone added a MAV to a 7230 with beater? Larry from Worthington Tractor Parts assured me no problem. It drives off existing beater drive. Would have to change pulleys to accommodate another belt? Well sure would like a second opinion on the project. Have gotten myself in a corner before on simple projects.

A MAV is very easy to fit. You could do it yourself. There’s more expense for a red MAV due to the rear ladder setup but certainly not that much. I have fitted two MAVS to 8010’s.

I would avoid the internal chopper and just finance the MAV in on the deal. You won’t notice the excessive cost as much that way.

You still have spreading issues with the internal chopper and i feel it does seem to muck with the sieves abit when in high speed chop.
