 Topic: Another Rookie question
Posted: 13 May 2010 at 11:20am |

D15 Series 1 with hydraulic loader. I have completely rebuilt the rear ram which drives the lift arms but until today have not used it. I have used the loader a few times and all works well with it. Today I decided to back into a snap coupler blade and then intended to use it to smooth my driveway. Coupler snapped into place and I moved the knob on the big valve which is supposed to allow me to use the rear lift instead of the loader. I engaged the hydraulic pump and the arms came to the top and stayed and would not budge. I turned the Hyd. pump off and also the tractor and went around and stood on the lift arms (215 lbs.) and they very slowly came down. I repeated the procedure, started the tractor and engaged the hyd. pump and the arms came up all by themselves again and the controls don't seem to have any effect so I shut all of and again stood on the lift arms to bring them down. I just left it and walked away. Ideas??? It is probably some silly thing which anyone who had ever used a tractor would know but I haven't and I don't. Dave PS - I forgot to say that I have the loader off of the tractor right now. I installed quick disconnects so I could remove it when I didn't need it. Would that effect the operation of the lift?

What about the traction booster lever, is it at the bottom of its travel? if its not put it down all the way and see if that helps. JCinPA

JC, the traction booster hasn't moved since I got the tractor. Loader hydraulics work. I saw it work, such as it was, before I bought it. Dave

Jimmy, I had that happen to a D12, turned out the traction control valve was stuck. That is the valve the snap coupler bell and spring are attached to. Sorry, didn't mean to end that sentence with a preposition.
That is the valve the snap coupler bell and spring are attached to, dammit.

Well I should say thats a much better way to end your sentence Dave. Um---whats a preposition?
Yea sounds like a stuck valve. Maybe check the linkage to the Traction booster lever and from the snap coupler bell to the pump. JCinPA

A D15 series I should have a rate of lower adjustment under the gas tank on the left sied. Give it a turn or two to increase the lower speed of the arms. I know the series II doesnt, but I think the series I does and I know the D14 does. Good Luck.

Well, Im off to camp again to check the traction booster and see if there is an adjustment where skipwelte says it might be. I'll report in later. Dave

Well, I could not find an adjustment but I did look over the traction booster lever and gauge and lines and found a leak in the small line that runs to the rear of the traction booster gauge (gauge doesn't work!). When the hydraulics were running there was a steady stream of Hydraulic fluid running from that fitting. So, I have that ready to go back on with a new compression fitting. Would that have caused this difficulty? Why did A/C ever have a traction boost anyway. All I ever hear is problems. Dave

The AC Traction Booster system worked very well, when adjusted and monitored correctly. The whole system was is based on the premise that as the implemented pulled harder, the tractor would automatically raise the rear arms to transfer implement weight to the rear wheels and improve traction. I had a D19 with a working guage that I restored a few years ago and it would pull 4 14's very well, even in tough soils. The guage was always moving and you could hear the pump bumping the arms up quite a bit, but the tires hardly ever spun plowing in 3rd low range...lol.

Ok, sounds like the traction booster may be out of ajustment. Youll need an operators manual to set the feedback link and sensing spring. Properly adjusted it still takes some wieght to bring the arms down, but they shouldnt come up all the way by themselves and it could be like Dave Richards says, the traction booster valve is stuck-thats why you need to go thru the adjustment procedure.

Thanks guys. I will get my operators manual back from a friend and go through the procedure. Hopefully that's the problem. I will report back. Dave

Well, I had a decision to make....do I just let this post die or do I "fess up"? I took my neighbour over to look at it. He's a D14 owner and a mechanic by trade. He said "show me" and I did then he reached up and hauled the hydraulic lever down below the bottom position and the rear arms came down. He looked at me and grinned and said "pilot error"!!! So, I learned not to just follow what was shown me by the previous owner. Red faced again. Thanks for all of the support here. Apologies.

Dantforth, BTDT, in spades!
I bought a 1948 WD a few years ago. When I went to look at it the owner told me that the hand clutch slipped, now that would be a deal killer. I fired the old girl up, put her in gear and away we went, stepped on the brakes and we stopped, pulled back on the hand clutch lever and away we went. I did everything I could do to get that hand clutch to slip but it worked perfectly. As I returned to the puzzled owner he asked me what I did and I told him that I just pulled the lever back the way it was supposed to be. He then confessed that a John Deere guy told him forward to go and backward to stop. Live and learn.
Glad you had a good outcome.

one thing I remember from English class (and possibly the only thing..)
A preposition is not to be used to end a sentence with.
