Yes you can, as long as you have a Super D with a hydro.

The Fox RWA unit is a bolt on/plumb in affair. Any model newer than a Super D and up, excluding the 6460,6660, and 6860 models will fit.

Or, you can add almost any RWA system, as long as you can get the correct flow volumes and controls, and don't mind doing some fab work for the mounting of it. My Super D has a RWA unit off of a John Deere 6600-7700 combine. Works great. PO had done some extensive fab - did a great job on it.

If you do purchase a RWA unit, be sure to get all of the solenoid control valves.

Best of luck!
 
Nope - no deal.

If you are having some trouble thu wet spots, and on hills, check the operation of your brakes. If they do not work, those machines are real hard to work with while pulling a load. I have a 2 wheel drive gasser SPF, and once I fixed the brakes, I have very little trouble - with out the brakes working, it was a maddening experience trying to chop aload of corn up a wet, clay hill...it would slide/spin everywhere. Also helps while turning.

Even with the RWA, you need operational brakes, as a hydrostatic assist applies flow to the area of least resistance; if it is tied to the main supply line of the hydro. In the diesel SPF with the RWA that I have, when I start getting stuck in deep mud, and the fronts start spinning, I feather the front drive brakes to divert flow/power to the RWA. I rarely get stuck.

All the brake parts on your Super D are Wagner, and they are all serviceable/still available. You just need the numbers off of the wheel cylinder or master cylinders or pads. Usually the wheel cylinders leak - the rest of the system is usually OK.

Good luck man.
