I am very anxious to look at this again. I think you are onto something. I think I’ll try it in 4wd and then 2wd. Curious to see how much difference there is. probably won’t get to it for a day or two.
If my tires hopped 14″ every revolution I think I would notice that. I think I’ll have to rethink/remeasure again, Something is definitely wrong. If I subtract the front wheel, 82″ from the rear wheel, 127″ I get a differance of 45″. If I add the 45″ to 82″ I get 127″. I think instead of leaving the tractor off the groung and measuring the travel I should leave it on the ground and push it along the ground for one revolution of the rear wheel and measure the marks. on the ground.
I tried everything suggested. I believe that the tires probably are the problem. There definately is a fair amount of wear on the fronts. I jacked up the left side of the tractor and in 4wd rotated the tires. The front and back did move together with no binding. I measured the circumference of the front tire and rear tire. The front tire measured 82″, the back was 127″. I marked the bottom of each tire and the concrete at the bottom center of the tires. I rotated the back tire one complete revolution (127″), the front tire rotated a total of 113″. That is one revolution (82″) plus an additional 31″ . This in itself doesn’t tell me anything since I don’t know gear ratio. I ran the tractor in 4wd on grass and blacktop and tried to look for the front tire to slide. Can’t tell like this. I have no sand or fresh dirt to check the tread pattern so I am going to wait until there is snow on the ground and try it again. I really think this is the problem, It makes the most sense to me.
Thanks for all your help
I’ll let you all know what happens.
I bought a stethoscope today. Will try that while I have someone sit on the tractor while moving.
The ideas about the tires is something I am anxious to try. Since there are no mechanical issues that I could find this makes a lot of sense.
I have a full set of turf and a set of ag tires. Have the Turf tires on no., I know I had this same binding problem with the ag tires since last winter while I was plowing snow.
I appreciate all of your help!!!
David, I have not tries a stethoscope. I do not have one, I’ll get one this week.
Bert, I had all shafts out of front drive, all gears, bearings and splines look including drive shaft. I saw nothing unusual. There is something I am missing.

When the tractor rolled down hill I did feel the binding . The tractor did eventually stop hard as the ground started to level out.
I jacked up the entire tractor and turned the drive shaft using a pipe wrench I didn’t feel anything unusual.
I then laid under the tractor and turned the front wheels together in the forward direction, then in reverse. This caused all wheels to turn while in 4wd. Although hard to turn wheels like this there were no parts of the rotation which increased in resistance.
But as I said in an earlier post without weight on wheels everything works fine.
David, what you are saying is correct. Thanks for looking into this for me.
RonJ, your statement #1 and 2 is correct. #3 is correct except while rolling down hill I do feel the binding at each revolution of the wheels and the tractor does stop sooner than it would if this problem did not exist. I also explained that I did the same tests with a heavy load in the bucket. The extra weight helped to carry the tractor further down hill but the problem was still there.
I appreciate all your attention to my problem.
Agpro4x4, There are no brakes in front axle.
Ronj, Nothing has changed, still binds up as before.
