I read through about 75 responses to T/a questions and haven't found my answer yet. Help? Found a '46(?) 300U with a homemade front hydr. blade, a fast locking hitch system in the rear but it has a spot to hook a top link in(??), p/s, it starts immediately after a tug with a small puff of smoke, rear tires about 75%, fronts are auto tires. The guy wants $500 for it. The T/A doesn't change at all. He thought it was stuck in low but it'll outrun the 9N in 5th so gotta be high, right? What would the diagnosis be with it not changing anything when I pull the lever? I'm thinking maybe just a clutch adjustment? Don't know. Thanks for any help, as always. Loren

Oh, and there's a 2-16 plow and 8' sickle bar to buy with it for next to nothing it sounds like.

Ok Loren let me brefely explain how the TA works. When the TA lever is forward you are in direct drive. When the lever is back your in the low range side. There are two clutches, the main clutch and the TA clutch. When in direct (TA lever forward) the TA clutch is engaged and the whole planatery TA unit rotates turning the input shaft into the transmission. When you pull the lever back you disengage the TA clutch and the rotating power goes through the planatery reduction gear set giving you the lower gearing to the transmission input shaft. So If the TA overrun clutch system was shot your tractor would just plain stop when you pulled the ta lever back. The fact that nothing happens when you pull the lever back tells me that the TA clutch is not releasing for one reason or another. It could be the linkage is out of adjustment. My 400 diesel did that once and it turned out to be one of the bolts that attach the TA pressure plate to the TA flywheel. There is an inspection plate over the TA that you can take off and make sure all the pressure plate bolts are tight. Get you a manuel and adjust the TA exactly as instructed. Let me know what you find.

I've had my 300U for almost 20 years and you would have to pry it from my cold dead fingers! $500 is a great price if the only thing not working is the t/a. It may be the adjustment, may be the t/a but I think you can get a full rebuilt t/a for $500 or so and have it all fixed and still have a great tractor for a lot less than you would pay for something else that can do the same work as it can.

You can't go wrong at that price, if T/A never works. I'd buy it & worry about T/A later,you don't have to have it any way. The 300U was built in '55-'56. Good dependable tractors. Is mower and plow 2-point or 3-point? Where are you located, here in the southeast, $500 would be a good buy for what you described. If you decide to buy it, get a manual and post back here, plenty of people on here to help you with the adjustment.

You know, I didn't look at the hook up on the mower. The plow fits the tractor, my guess is the mower does too since they have been on the same farm forever with the 300 being THE tractor. I'm in the NW, around here anything that's good useable is worth 2-3 times that. There's a line leak that'll be easy to fix, general seeps to fix. Definitely figured on the manual and already told the guy we'll be over tomorrow morn to haul it home. Yeehaw! We're stylin' now! LOL

The TA is probably stuck in high range; it may just need a clutch adjustment (EXACTLY according to the book), but don't count on it. If that doesn't work, you still have a useful tractor even if you don't fix the TA - probably for quite some time.

The 300U is set up to accept the toplink for a standard 3-point hitch, all you need are the adapters for the bottom portion of the hitch, which hopefully come with the tractor.

For $500, it's pretty hard to see how you can go wrong, especially if you get the plow and mower cheap. Do spend a few bucks for an Operator's Manual (Binder Books). Good Luck.

I was hoping someone would say that about the T/A and hitch. It was kinda sticking in the brain that I could use adapters of some sort. I'll do a good exterior cleaning on the thing since it's so oily everywhere and then get a manual and see what I find. Thanks again.

Loren,

I bought a tractor with the same symptoms. Mine ended up being that the gizzmo was stuck in high range.

The local shop here says that there are many things could cause this result. That T/A system is kinda complicated and must be adjusted exactly as the book says.

A 300U would probably be a '56, wouldn't it?
