Lift arms

[2tractors]

I came out this morning to find the arms down, thought it had fixed itself but after cranking it rises and stays, pulled the cover and didn't find any loose parts in bottom, i could reach in and move the lever and get them down, seemed to work somewhat but the draft control movement makes it go all the way up and stays until i reach in and move the lever. I think the fluid which was thicker than molasses is the problem. Should i give it a good rinse with deisal or just drain and swab?

Does control valve move with control lever? May need oil change if sticking, could need lighter weight oil.

Not at first, both draft and position control were inoperative until I reached in and moved levers, if i pull the top i understand there's something that needs disconnecting from the inside, probably won't go to that extreme to clean.

Are you sure you have the control levers in the correct place?. If this is a 35 then the lever next to the seat should not be pushed all the way to the bottom, but just to the 'lower' position. the outer lever should be about 3/4 way down or between the sector marks on the quadrant.

Sorry, I should have posted this photo. the outer lever is in the correct working position and you will see on the inner lever the section marked response. do not push the lever very far into this section, or not into it at all.

I have always pulled the top cover and removed the pump in all the tractors I have bought to get it really clean in there. They all needed it. If you don't want to get in that deep, draining the molasses out and cleaning as much as you can through the side covers will certainly be a big improvement. I have been using the 15W40 oil recommended by John UK and it works much better in the cold.

Now I am confused. I thought they ALL fell after a few minutes? weight or not, like a safety feature? My poor Allis CA held up a 7 foot mower for two weeks, but the -anything- I hook to a fergie drops soon after.

Yeah, tell me about the position control. My new toy, a 4 foot post hole auger, dug an 8 foot hole last week. zigged when I should have zagged I suppose....

Sam you may be onto something as i had both levers all the way down. While working with it and after releasing each time it rose, once the position control was half way and the arms likewise, but when i moved the draft all the way down is when it again rose to top.One of the upper gears and shaft is really rusty like water seeped in. What needs to be disconnected to pull the top cover?

NEVER use diesel or kerosene to wash out the Hydraulics as you cant drain it all out and it will dilute your new oil. The correct way is to get the oil as hot as possible by working the tractor which will be difficult this time of year I know. The only way if you can get it hot is to drain it and leave it draining at lest overnight and then top up with correct Oil and when th weather is warmer, change the oil properly. It is most likely the Control Valve sticking due to the thick oil but it could also be adjustment too. From what you say the Valve isn't moving or not moving as much as it should do. Make sure that you don't put the Draft Lever to the top of the Quadrant as that could make the valve stick if the settings are wrong. Just use the Position Control Lever to lift and lower for now. The Pump Control Lever that comes up out of the oil, should be JUST touching the levers that hang down from the top and it should also move freely as it is attached directly to the Control valve, if it doesn't move freely then the Control valve can't move either and this will cause you a whole heap of trouble. Unless you know what you are doing don't play around with it or you will only make it worse, get the information first....John(UK)

The Position Control should always return the 3 point to the same height each time you lift and then lower, if it doesn't and the height varies each time then there is wear in the lever linkage and possibly the cam roller for the position Control has a flat worn on it due to being seized. The system itself when set-up correctly is very accurate, any problems with it is incorrect adjustment or wear....John(UK)

 

[John(UK)]

That information is not correct....John(UK)

No.2 do you have the shop manual? There is trouble shooting with hydraulic system in my I&T service manual i'm sure it can answer some needed answers.

Wow. Well, the way I read this, you shut the tractor off? and came out to look at it the next morning? Like I said, all my MF anythings when off would have fell within minutes. I thought they were designed to do that. Not the AC. As far as a running MF tractor, yes, raises up if the lever is in the right position to do so, and stay up while runnning, in that same position... this is getting to be alot of typing.....

Tony, thanks for the clarification, let me make sure i got this right, up raises it and down lowers it, better get pen and paper!!Just kidding, I thought of you yesterday as i was removing the rusty bolts from the front end. I remember you saying how un rusty florida stuff is, well maybe compared to Mass.Someone must have parked this one in the ocean!

I wish I had a better pic of this girl holding up the mower, but the mower is about 800 pounds. It stayed like that for 2 weeks. A fergie to hold that up 2 hours would be unusual. So's I figure anyway.

Ok, since this is a Florida tractor, we will give it some slack. So if you turn it off, and the hitch falls, that will be OK with us. If you start the tractor, and the lever is set to raise the hitch, and it goes up, like it is suppose to, we're good- hey worst things have happened to better people! Us HF-ers have to go to battle with the technology we got... or something like that....I remember when C-span was following Rumsfled around his New Mexico ranch... he sticks his hand in a bin of plow bolts, and sez 'this is farm stuff' and he points to an old farmall and sez 'and that is a..ah... a tractor! yeah.. a farm tractor'. So we are doing good with what we a re-doing...
