I was looking in a brochure and the front tread width on a 5040 & 6040 is 52.4 to 56.3 inches center to center. The rear is as stated above. Now, the standard front tire for a 5040,6040 & 7040 is listed as 9.5-24(R1). I measured mine to be about 10 inches wide. The rear tires on mine (7040) are 16 inches wide (16.9-30 (R1). This probably just enough information to be confusing.Blksim said:In the operator's manual it shows the tread width as front being 55.9 inch minimum and 59.8 inch maximum. Depending on how you set it up.
Rear is shown as 52.0 inch for 5040 and 55.9 inch 7040 minimum and 67.7 inch maximum. Note this is center to center on your width. You'd have to allow for half of tire width from there. When I feed today I'll measure width of tires.

I wonder if your cast iron discs space the same as the standard version I'm running? How much weight do they add and do you use the same rim?
Thanks, fitz

I am going to have to rethink some of my plans to get an 80" box blade and tiller. Will have to step them up to 84" or so to cover the rear tracks. Good thing to know ahead of time.

IMHO, unless your place is very hilly and you are always working on side slopes, it is not likely your tractor will need to be more than 6-1/2 ft overall tire width at the back. If there is a row crop to straddle the rears may need to go wider. But if more width is needed just for stability, a different machine is in order.
