wheel configuration for A Farmall

Terry Hales · May 26, 2009

I am looking for any information on the various wheel combinations (including weights) that are possible for the rear wheels.( I am talking about the spacing) Any pictures or sites that you can give me would be helpful.
Thanks for your help!

I've seen the diagram to show the available rear wheel spacings in two different places -- the Operator's Manual and in the IH Blue Ribbon Service Manual for A/AV/B/BN.

Your range on the rears is from 40" to 68" in increments of 2". Narrowest is with the wheels dished in, and the rims bolted up to the inside of the wheels, with the lug on the rim on the outside. Widest is with the wheels dished to the outside and the rims mounted to the outside of the wheel with the rim lugs to the inside. Tread measurement is to center of rim

Scotty pretty well covered it. A couple small points I can add:

Depending on your tire size, you may not be able to set it to the narrowest setting. You could have a clearance problem at the fenders.

When swapping around to get certain widths while keeping the tires running forward, you will have to swap rims and tires from side to side. While doing this, keep the heavy cast wheel disk on the right and the stamped steel one on the left.

Rudi's Farmall Cub Manual site has a few manuals for the A/B and Super A. Go there and scroll down to find pointers to the sections for those models. I think there is an Owner's Manual for a Super A but not an A. The wheel setting information would be the same.

All good additional points, Jim.

The last one I'd add is to make sure you tighten up your lugs and check them periodically, wherever you set them. Otherwise they can get loose and wobble and egg out the holes and then your great-grandfather might happen to weld them to the rims so that you don't have as many options for tread if you want to keep your tire treads running the right direction, unless you're willin' to have the tires dismounted twice a year which your great-grandfather won't be willin' to do, so that you wind up cultivatin' with your tires ack basswards like they are in this picture of me with my brother on my lap on the old guy's BN that now sits in my garage.

Hi Terry,

The owner's manual has a diagram with all the possible combinations of wheel widths. You can get reprints from many sources so you can have one in hand while you're out in the shop.

Just FYI, but the wheel centers are supposed to be different from left to right on a Super A. The right wheel should be a heavy cast steel, and the left should be a lighter stamped plate steel. This is to balance the tractor out and keep it from tipping over to the left due to the offset engine.

You can add up to two 140lb cast iron wheel weights to each rear wheel of the tractor for additional ballast.

Thanks for all of your replies. I appreciate the information. My "A" has the heavier rim on the right side too, is that only on the Super "A" or the "A's" as well? (my serial number indicates it is an "A".) One last question:With the rims dish turned in towards the tractor, are the weights bolted on with the dish inwards also?

ScottyHOMeY · May 27, 2009

You're welcome and, yes, the weights and wheels are shaped to nest with the weight on either side of the wheels.

Jim Becker · May 27, 2009

All of the Super As came with the heavy right wheel disk. MOST of the old As did as well, but not the earliest ones.

Terry: Mkirsch is exactly right - his answer covers it all.
You really should have an Operator's Manual. With it you would learn all kinds of wonderful things about your tractor which would, in turn, make both you and your tractor happy.

Where is the best place to find a manual for the Farmall A?

(quoted from post at 16:25:01 05/27/09) Where is the best place to find a manual for the Farmall A?

Either right here (upper lefthand corner) or Binder Books.
