Thanks again for your reply. I'm a real rookie regarding tractors but have a vested interest in this mid '60's MF 203 (Perkins AD3 152 diesel, 3 spd., H/L and shuttle) that has seen better days a long time ago. It's got the 200 loader and the 222 hoe (I'm impressed you knew those models!) and while they do what they were designed to do, they need attention. That's another story. The shuttle aspect is a mystery to me. Currently, I can not engage forward or reverse (because of heavy grindage) unless I shut off engine, place shuttle in forward or reverse, restart engine, shift into H or L, and pick a trans gear. Then it will operate in either direction. Is that normal? Soooo, besides a heavy metallic, clanking noise while shuttle is in f or r, it seems to go. Another problem was that sometimes I have to stand on the clutch pedal and the tractor would still move for about 5 long seconds. Well, I got real brave and split this old digger to find out why these conditions were happening. So far I've found: an oiled down clutch (looks and smells like 90wt) a flywheel that has a depression where the disc contacts it that is about a 32nd" deep, and a reverse idler assembly that needs total replacement. Everything else seems/looks to be ok. Although input shaft end play is out of specs and shims are needed. I'm making up a parts wish list and now have to seek out all of them. I hope I haven't bought and created a big boat anchor. Thanks again for listening! Bob

Not at all Bob, most shuttle shift tractors work the same. The shuttle shift is a wet clutch reverser on these older tractors.

Should have a forward /neutral /reverse position, no need to use the clutch once you're in a gear, just stop before reversing

direction, but I can't help if you have a problem with those models. By the way which model do you have?

It would be a good idea to get an operator's manual for your tractor, loader and backhoe. They can be bought at, and have valuable information, like oil levels adjustments, etc. I know the 202 tractors came with a model 100 or 200 loader and a model 220 or 222 backhoe. There may be other models, but those are the ones I know. Should be a serial number tag on each piece, if it hasn't been removed over the years.

Thanks for the reply Dave. I think the questions might only have to do with the MF workbull series and in particular I'm after info on the use of the Shuttle Shift usage. Did I lose you right at that point?

Thanks! Bob

Sorry Bob, no I don't. I've got an old Ford about the same vintage.

Though I may be able to help if you have some general questions.
