Subject: pulling tractor pulls to the left
Date Posted: 14 Apr 2012 at 7:54pm
Could use some suggestions here.

WD45 pulls very well, but when I finally get the front end light enough to be light or lift just a bit, the tractor pulls to the left.

Today, I had to put on the right brake rather hard, therefore slowing down alot.

I aired up both rear tires equally, and measured around each tire, and got pretty close to the exact measurement. So its not like one tire is larger around than the other.

I am going to check to make sure my drawbar is coming straight back. There might be 1/4" play left to right that I don't think would make too much difference. Iif the drawbar is shifted off to one side more than the other, pulling with the drawbar shifted towards the left, could make the tractor pull its front end that way, right?

Any thoughts/comments?

Thanks.

You could put a little extra weight onthe right i have to do that on my wc just opposite

the seat is on the right tire and could be caising less slip on the right tire, then it would drive and go to left,

I've got the tractor balanced pretty well from left to right.
Last year I ran the Right Rear out a bit further, but this year, I've got weight distributed to be pretty equal while I am on the tractor.

your right tire is griping more than the left, put more weight on the left rim, or change a tire too grip different, take weight off the right,etc., it will be trial and error.

EricSWPA, it seems that putting weight on the right would make that tire grip more, causing it to pull to the left even more, right??

I don't understand how putting weight on the right would prevent the tractor from pulling to the left.

Could you explain more?
Thanks.

Well in my case the wc seat is off set so my weight is favoringthe right whell so i put usually a extra 100 lbs on the left to ballance the weight out so both tires have roughly the same weight on them for traction

Im backwards sorry i get confused easily lol but yea more weight over the left tire like i have to do on my wc

My WC pulls the right because the back tires aren't matched....I add weight to the left and it goes straight. You can always drop the pressure in your more dominant side and try it....trial and error works lol

Next time you go to a pull weigh each rear tire seperatly we had a gentelman had same prob turned out he still had some fluid in one tire 400 lds diff left to right

    Since WD45's never run out of power, then both tires are spinning at the flag? or just one spinning? If your brakes aren't dragging , the culprit  may be in  the differential  .

We always have to put more weight on the left hand side of our WCs. Kip

hi Gary. It appears that both are still pulling at the end. It all happens so quick, I am not 100% sure about the left. If I ride the right brake, the tractor will try to turn back to the right, which makes me think the left is pulling ok, but as soon as I let off the brake, the tractor pulls back to the left.

I have jacked the tractor up and spun the tires by hand, and it doesn't seem like the brakes are dragging.

What could be going on in the differential to cause this? (I guess a bearing somewhere could cause drag).

It might change from track to track.
I could have to do with how hard the track is packed. Maybe tighter on one side then the other. How were the other guys pulling or were you on a track alone?

The universal answer to all questions is yes, how much do you want to spend?

I had this happen on 3 different tracks. This past weekend, the track was very tight, and other tractors stopped in this one particular spot on the track. I was able to pull through it, but that's when it pulled to the left.

Last year, twice when I attempted to get the front end a little lighter, she pulled to the left then also. If I keep the front end heavy, it pulls straight.

Worn bearings , galled gears, worn out shims and spacers.    I think farmall   H's and M's are more suseptable to pulling to one side or another and spinning only one wheel at the end but Allis aren't immune to that.  I've had it happen on certain  very hard tracks with a lot of crown. Soft tracks don't seem to be a problem.   It might help to shift weights from one side to another, or adjust air pressure  but I don't think thats a cure.   For now I would keep equal weights and air pressure and find someone , two is more better , people to take photos, or even better videos ,from each side, so you can see whats going on each side of the tractor.      Every friggin track is differant, watch how the guys before you are doing and stroll  down the side of the track, watch how the other guys finish and their route down the track, others might be fighting the same thing.   Gary
 
 I need to add that if I throw on an odd number of weights  to make a class, on a WD , it would go on the left.    There are rules... and exceptions.....

I think it was that darned St. Marys County clay!!!...If you wanted to see something hook hard to the left, you should have seen my 45 in Callao Sunday.  Foot as hard as I've ever had it on my right brake and me leaning to the left to keep it straight.  I was near horizontal in the seat.  Keep doing what you're doing, that 45 of yours is a beast!

Don't over-think it.  Carry some extra weight on the left side (I would start with 200 lbs) and see what happens.

By the way, I got to thinking---------what might be going on is just the normal reaction to engine torque.  That could be putting some extra load on the RH tire, causing the tractor to go left.

Also might want to check the brakes make sure it isn't " riding the brake" same thing happened on mine I took the brakes apart and it fixed it right up

I had the same problem. I figered it out to be one 11 inch rim and one 12 inch rim. Bought 2 new 13 inch rims and it goes straight now.

pull ing to the left is quite normal with modified tractors it is due to the torque direction of the engine, for the same reason a pilot must apply right rudder on take off.

Move the seat to the center or hang 200 lbs on the left side where the seat would be if it had the seat mounted on the left side instead of the right. If you weigh 300 lbs then hang 300 lbs to the left.

It sounds like the drawbar alignment may be the main issue if it's shifted slightly to the left, that can definitely cause the tractor to pull that way when the front end lifts. Double-check that it's centered and secure. Also consider weight distribution, brake drag, or subtle differences in tire traction under load, even if pressure and size seem equal. Fixing the drawbar is a good first step.
