I got the MF85 home and also bought a reprint of the factory manual. The tires are set pretty wide and I want to make it narrower. The manual states that a tool is required to loosen the rear rim clamps. What does the tool look like?

Looks like these rims haven"t been adjusted in years, so may be opening a can of worms.

Don't know about your 85, on my 150 the clamp lock bolts have a 3/8" square head. I had to weld a 3/8" drive socket to a 1/2" drive socket to turn them out. Also heated them with torch.

Yes, that is how mine are. I was thinking an 8 point socket?? A couple are already headless.....looks like some one had twisted them off long ago.

Also found out today, the hitch is CAT-2, everything else I have is CAT-1.

Anyone know how many bottom plow the MF85 will pull? When I was looking for a Ferguson or Dearborn 2 bottom plow, found a lot of 3 and 4 bottom plows cheap.

A twelve sided socket and lots of heat. That 85 should handle 4 bottoms or even 5 depending on what your plowing. They make bushings to change catagories.

I was wondering if all MF wheel locks are the same? I need a couple as 2 are damaged. What other models share the same locks as the MF85?

Good news, bad news. The only ones that I know of that work well are used by tulip farmers... wide rows, narrow rows, like the e brake on a car, if it isn't used constantly, those cams want to stay wherever they are.
Easiest way to avoid bad news? Do nothing. 2nd choice? Loosen the 2 bolts on each clamp and slide the center in or out of the rim to the point you like, then take out the arc welder! Otherwise, once you mess with those cams... you may live with a clunk clunk clunk for ages -or worse. I belive a couple years ago it was David P? who posted a little incident he had by his mailbox with these things. I suffered with these PITA PA rims thru 2 milleniums... with my old AC's, and now, the set that came with that F40, now replaced with 6 loop 'normal' rims and centers...

I used a good flat ended punch and a hammer. The punch was about 3/8 diameter on the end and ground flat. Set the punch at an angle and drive the cam lock in the unlock direction. The first one can be tough but as tension is released from the rim they
get easier. Also pick up a can of power lube and soak them the day before you start.

The original tool will look much like a bud wheel wrench. It is 2 pieces, has the lug nut size, on the big end, and the clamp nut size on the smaller end. Both pieces were of the same length, usually as long as the tractor's tool box. With respect to the clamps, themselves, I wouldn't even try to move them, on an old rusty situation, too easy to snap off the head of the cam. Notice I said cam. It's not threaded, it is an eccentric cam, that bolts to the wheel center, and clamps outward, against the rim. Proper way to get them moving is to roll one to the top of the wheel, and remove the 2 5/8" bolts that hold it to the center. Slide it along the rail, and make sure you catch the rail slide, that goes between the cam, and rail. Next, soak it in your favorite penetrating oil, or heat with a propane torch, and melt some beeswax into the cam bearing area.(there are no bearings). next stick in a vice, and put an air impact on the head and alternate back and forth, till it moves. I Have also had luck hammering with a brass drift, in and out, on the cam itself. Once you get it moving, pop the snap ring out of the back, and pull the cam out, forward, and lube all up with neversieze compound.

I haven't looked yet.....will the centers off my TO20 fit the 85? I would have to get wheels and tires as the 85 is 30 inch I believe.

Tony, thought the wheels on the Brimfield F40 were junk? Or at least one was, seen them laying outside the back door of that shed.

The more I look at this MF85, thinking it is more tractor than I need..... I should of went with a MF35 or 65, but couldn't pass up this deal.

Thank you for the great info. Two of the cam heads are already gone, so that may be in indication of some one else had failed adjustment in the past.

Oh yeah 85's are impressive! Ya got to have one around that's bigger than the fleet, that's why I keep my 3165, even tho it hardly moved all last year. Like insurance, when you don't have it, you'll need it.
So what size are the rears? I thought they'd be 38's or something. The rubber good? There was a pair of 30's on CL in Ludlow for over a year, I don't know what happened to them.
Those power adjust are such pigs, yeah, the F40 had a set, they actually looked worst than they were, I took off the rubber, welded a couple patches, and put an extra nice used set of 13.6x28's on with new tubes... like yours, had to toe in the clamps on one wheel.... didn't go more than an hour without the 'clunk clunk clunk'. I about popped a cork after all that work. So right now the 40 has another nice set of rubber on 6 loops, but I will just weld the clamps one of these days, and put em back on the 40.... the rustoleum paint job came out so good... the idea sickened me.

You can take them off, drive the cam out, and weld new heads on them. I have done it, not pretty,but pretty cheap!
