wide ft for wd45

I have a chance to buy a wd 45 with a narrow ft. In our hills I would like to change it to a wide ft end. Does any one know if a d 15 ft will fit the wd 45 as I have a friend that is parting out a d 15.  If it will not fit does anyone know of one for sell. This will be my first allis tractor, I do have several combines and rebuild them as a hobbie. Have done 5 this winter for myself and other farmers.

Around here in central mo the wide front still commands a high price, there was a big salvage yard that is gone now but was in business since the 50s they had a list for wide fronts and you had to sign up and the price was 750 and there were about 12 names on the list at any given time,  they can still be had around here for around 600 but where you are in the world determines price.  1 out of every 250 tractors (guess) were wide front around here years ago as this was cultivation country, if MO isnt too far away give me a holler as I know where there are several parts tractors with wide fronts, Dustin

Changing to a wide front end may give you a feeling of more stability, but it is a misconception by all too many. The front axle pivots and doesn't help at all with stability until the stop is met. At this point, you are well past a safe position with the tractor. Use the widest setting for your rear wheels to help the most and stay off the sidehill if you think it might tip.

Rollover Protection

The best rollover protection advice I can give is to buy a tractor with a low center of gravity, and then operate it safely (avoid driving up or across steep slopes, slow down when turning, never turn sharply with a raised front end loader, and never hitch anything to the tractor other than at the drawbar).

In terms of the tractor's basic geometry and configuration, the biggest factors in determining its resistance to rolling over are the center of gravity and the rear wheel spacing.  The lower the center of gravity, and the wider the rear wheel spacing, the less likely it is to roll over.

The configuration of the front end matters, but not nearly as much as the center of gravity and the rear wheel spacing.  A "wide front end" is not rigid like the tractor's rear axle--it's designed to rotate about the long axis of the tractor, up to a point, so that the tractor can drive over uneven terrain and still keep both front wheels on the ground.  Until a tractor tips far enough that the wide front end rotates all the way to its stopping point, the wide front end doesn't provide any more resistance to overturning than does a narrow tricycle configuration.  My point isn't that narrow front ends are safe--rather, it's that wide front ends don't make a high-center-of-gravity tractor safe either.  If you're buying a tractor to use on hilly terrain, choose a utility tractor for its lower center of gravity.

If rollover is a real concern for you, consider buying a tractor with a professionally-installed rollover protection system (ROPS).  That pretty much rules out any tractor built before the early 60s or so, when ROPS first became available and when tractors began to be designed for them.
