1980 Long 360
1980 Long 360 - Replaced the PTO shaft in this machine a couple weeks ago, put it all back together and refilled with new hydraulic oil. Everything seemed to work fine for a few minutes, but then the 3 point wouldn't lift at all. Read the manual and got an idea to remove the pilot valve and clean. once I put it back together and started the tractor, the 3 point went all the way to the top and now won't go back down. Any Ideas? While the tractor is running, I can slightly loosen the Cylinder safety valve (I think that's what it is. The section that displays this in the manual is very blurry and hard to read), and the 3 point will drop back down. when i tighten it back into place, it raises back up, almost as if something is stuck not allowing fluid to drain back out but loosening the safety valve seems to temporarily accomplish this. One of the sections in the manual references check the possibility of a stuck drain valve and suggests to disassemble and inspect it, but I'm not sure where to begin on that one.

Please bare in mind, this machine was bought new by my grandpa almost 40 years ago, and has been parked for nearly 10 years. I've only recently started trying to repair it, but I really don't know anything about the history of this machine as my grandpa passed away along with any known issues with this machine.

For anyone interested, I found my problem. It worked for a bit after getting it all back together then quit. Come to find out, I lost a cotter pin holding a joint in place on the draft control handle (i think that's what its called) that you use to raise and lower it, and losing that cotter pin allowed a joint to slip loose just enough to not allow the draft control to make contact with the assembly that triggers the unit to raise and lower. Long story short, it was an external linkage type problem and luckily nothing inside the unit requiring me to tear into it internally.

Guess you got lucky, those Longs are a bit strange in a few ways; hopefully you have at least the operator manual that came with the tractor. If the 360 is like my 460 (good chance) there's a wierd thing on the 3 point hitch - I don't recall the details, other than if you move the draft control when the hitch is in the wrong position, IIRC you have to take it apart to make it work again.

I'm not sure exactly where my operator manual is right now, but if you don't have one post back here and I'll find it for you.

When I read about that, I made sure everything was done correctly - in my case, I don't USE draft control at all, so I just remember NEVER to move that lever. I can get away with that, because I have another tractor AND a backhoe so the Long only gets used for NON-ground engaging implements.

BTW, the factory those tractors were made in got demolished sometime around the '90's and is now a shopping mall or something, so any parts you find are gonna be a roll of the dice. If you haven't already found it, there's a little info here

HTH... Steve

Sorry, just re-read your first post - sounds like you may already HAVE the original operator manual. If so, and you haven't already found that warning about the draft control, you should RE-READ the manual again...

Sir, I have the service manual, but have searched high and low for an operators manual for this thing and would greatly appreciate it if you have one available. I inherited this from my Grandpa who bought it new 40 years ago, and so far these longs, while a bit strange, have proven to be pretty basic, simple, and straight forward. I considered selling it and rebuying something newer, but I'm really liking the serviceability on it so far. This thing had loads of minor issues when I got it and I have corrected most all of them with less than $300 invested so far. Because it is 40 years old though, the service manual obviously wasn't originally created in a digital way and all copies i've found appear to be poorly scanned copies and they are very difficult to read and understand the pictures, so most things I've had to figure out on my own. I get some basic very general info from the service manual, but have learned tons about this machine by simply turning the wrench myself.

Thanks for the link to tractordata. that was a very valuable resource as this machine has little identifying information on it, and thanks to that website is how I finally identified it was a model 360 (though i'm not sure the difference between it and a 360c). The oil filter i bought at Napa which matched the one I pulled from it, indicates it might be a 360c as the filter for a 360 is much longer and I don't think would have the clearance for installation on my unit.

Anyway, thanks for the response and I appreciate the info. BTW if you are having trouble finding parts, I've been getting everything I need from tractorjoe.com

It'll probably take me a few days, but I'll try a couple different ways of copying my 460 operator manual - I'm thinking that high res jpg's might be easiest, could just send them email.

It's interesting that both tractors share quite a few common parts, they use the same engine but the 460 is rated higher horsepower at least partly because they're rated at different rpms.

Also, if you look at the tractordata link again one version of the 360 used the same tranny as the 460 (6 fwd, 2 reverse in 2 separate ranges) while another version mentioned (barely) an 8/2 tranny.

Thanks for the tractorjoe link, I'll check it out... Steve
