We took the 200 out today and mowed some weeds in the pasture at a place we farm 7miles from home. It has been awhile since I did anything with that tractor,and I noticed how much longer it took to get there with the 200. I guess I'm used to my son's 6430 on the mower, and it goes 27 miles per hour down the road. That got me to thinking, and sometimes that isn't a good thing. How hard would it be to put a 3 speed power shift transmission from a 7000 in a 200?

Cannot be done. But, you could take a whole (pretty much) 7000 tractor and cover it with a 200 platform, fuel tank and hoods. It has been done once before (seen pictures) but wasn't done exactly the way I would have done it. Be glad to help you with the project.

I dunno. I'll have to chew on that awhile. That would have to be a winter time project for me, and I need to take some time off sometime for knee replacement surgery. I was thinking about pushing that back until December. I havn't asked the Doc yet how long the recovery time will be, but at least a couple months probably. Probably cheaper than spending the winter months in Arizona and more fun too. Thanks for the reply.

Get a second tractor and equipment to store at the remote farm and take a pickup back and forth.

More tractors is more better, as they say.

Well, we have 10 tractors on the place now. I'm to the point where if I buy another one I would have to first truck it from the purchase address to a neighbors house. Then have the neighbor drive it over and tell my wife he is bringing the tractor back that he borrowed from me. It might just work!

You can (I know. It's been done before) take a 190XT 4-pinion differential ring gear and install it in the 200 and do some strategic shimming and mate the XT ring gear to a 200 pinion gear and speed things up 10%. So, a 200 with 18.4 x 34's does 15.5 MPH at 2400 RPM, this ring gear swap would change that to 17. 1 MPH. If you already have 18.4 x 38's it should now be doing 17.0 MPH, so the XT ring gear would step that up to 18.7 MPH.

The 200 does have 38 " rubber on it, so that does speed it up on the road a little, but the truth is that I just love that 3 speed power shift on the 7000. That extra range at the top of every gear is exactly where it needs to be, and it makes the tractor more useful in many situations. We always thought we couldn't do without the neutral position in the power director, but I guess that wasn't as important as we used to think it was. Our 200 has 11,000 hours on it, and the original power director. I believe that AC's power shifts are pretty durable too. It would have sold more tractors if they had put it in the 200.

If you could put the 7000 3 speed Power Shift in a 200, you wouldn't have live PTO. The 7000 has independent PTO.

If you could install the center section of the 7000 (called the torque tube) into a 200, you would indeed have a true live/independent PTO and the 3-speed Power Shift feature. The problem is the torque tube from a 7000 will not even come close to bolting up to a 200 rear end. Can't be done.

The 7000 drivetrain should have been what the 190/190XT originated as.
