Front wheel wobble

If they both do it, then more than likely slop in steering gear, if one then loose bearing or bent rim.
 
The AN should be a single front wheel in a yoke. But could be bad bearing or bent wheel or bearing or gear in pedistal. He says wheels so sounds like he is not sure of model.

You might consider adjusting the front wheel bearings.

Take a look at the [b:654c4848f0]ROLL-O-MATIC FRONT END ASSEMBLY (A ONLY)[/b:654c4848f0] diagram below.

Hope this helps.
 
The standard A is a tricycle model with 2 wheels close together. The AW is the model with the wide front end and the AN is the one with the single front wheel and likely 42" rear wheels for a higher clearance as that tractor was designed for use in vegetable areas as with that single front wheel you could cultivate narrower rows and a lot of times that also required more clearance for cultivating. The AR is a standard tread or wheatland style of tractor and when the 60 series came out in 53 the AR was simply a 60 standard, the rest 60 row crop as all the row crop models had the split pedistal that you could interchange the front ends on as did some of the later A series have and with that they just carried the A and the AW and the AN were droped as all could be fitted with either front end. I am not sure when the split pedistal came out but think in either 51 or 52 but think in those years tractor could have beem bought with either the non interchangeable front end or the newer interchangeable front end. Somewhere in all the papers I have I have that information but could take me a year to find it.
 
My 50 wobbled bad on hard surfaced roads due to a bent arm (item #8 in James' parts drawing). It gave me fits until I figured it out. It's hard to tell a bent one from a non bent one. The wheels lean out at the top, so that bend in the arm is necessary, but if you look straight down on the arm, the plane of the wheel spindle and the pin that bushings #6 slide over should be parallel.

I just replaced the bushings #6 in one side - it was getting close to wearing through on the inside bushing, but it had no wobble. Found it while cleaning/painting.
