Tractor Shaking

[Puffie40]

Not much can be done for out-of-round tires. Bumping up the air pressure a little and leaving the rear end up on jack stands over the hot season MAY help.

Thank you everyone for your suggestions. It's appreciated.

Everything is bolted up tight/secure. Nothing is loose. I therefore am going to look at the tires. I'll switch them out with tires from one of my other cub tractors (I have 5 other cubs) and see what happens. Thanks again for the advise. John

John, if your tires are the old originals, that have the continous tread pattern, they're the culprit. When they were new and soft, they might not have been too bad, but old & hard, those are the most miserable riding tire there is.

This is the type of rear tire that Gary is referring to...

Right on the money Gary and Don--I have the originals on one of my cubs and its like riding on square wheels regardless how warm the weather is!!

I have seen this pic many times, but just noticed something that I have missed before. The rockshaft rod and hand lever is painted implement blue. Most rods and rear rockshafts are painted red. Makes sense to be blue as it probably was part of the add-on for a cultvator.

Everything from the master lift unit forward through the universal mounting frames was intended to be red. The earliest ones were painted blue due to the post WWII pigment shortages. They switched to red as soon as pigment was available in large enough quantity.

My cub would shake violently when my driveshaft had one crack around it.
I guess it was wobbling. It finally finished cracking. It had the first crack being a dark gray, older. The final crack is a light gray it's newer.

Perhaps some here are not old enough to remember when tires started using nylon cords in the fabric body. Nylon was a good choice for many reasons. Earlier tires used rayon (made from wood) which had a much shorter service life than did the nylon. But the nylon would "flat spot" even overnight and the ride would be rough until the tires got warm. That was the major drawback to nylon for tires. This time of year, Cub tires will not get warm as the speeds are quite low. Nylon fell out of frequent use with the development of newer synthetic fibers.

I sure remember those bumpy rides on the old Dodge.

My first set of 32" 1100-15" on my 4x4 truck would have flat spots in the mornings. She would thump, thump, thump for a while.

I painted my rockshaft lever blue. It's just not quite the right shade We guessed wrong. Maybe after I get a complete cultivator set assembled and if I paint the cultivator, I can fix it.

My cub has a flat spot in at least one of the tires after it sits. I can feel it every time I take off over the concrete after starting it.

Reviving this old thread. Does anybody know why this tread pattern went out of favor (if for any reason besides the fact that they wear funny and eventually ride rough)? I have these on my 1946 B and they ride terribly on pavement.
