    Posted: 17 Sep 2024 at 9:23pm
I am contemplating removing the rock shaft housing from my 7040 to lose some weight. I saw pictures of somebody who did it before on this site. I plan on replacing the housing with a half-inch piece of aluminum plate. I will be the first to admit that I do not know much about what is going on inside of that housing. What can I expect when I take it off? What kind of linkages will I have to separate?

This is not my tractor in the picture. This is what I plan on doing though. Interesting fact that they did not have a three-point. I plan on attacking it Saturday morning. I am just curious as to what I am going to find when I take those bolts out and try to pick up the lid.

So, that's not your tractor with the 92 lb suitcase weights hanging from the rear axle?? Good. That isn't the best set-up and I'd never do it like that. Keeping the rear tires as NARROW as possible makes for the best pulling distances. Get the tires in to where they almost rub the cab is the best.

Appreciate it Doc. Ever pull a rock shaft housing before? I'm hoping to not have to remove the cab.

3 or 4 over the years. Comes out from under the cab with a homemade lifting tool.
