Hey fellas...thanks so much for all the input!
Tx Jim, you got any hills down there?
Great fuel economy...I'll be hard pressed not to run the M108 for running the discbine...we'll see.
3R, thanks for the heads up on foreman ET. you know if he's running R1s or 4s? The 8540 looks to be quite a bit more tractor than the 7040...i'm sure you love it. Cant you add the cast centers now? I did get a look at rjkobbeman's posts. Really thinking R4 is the way for me.
wmonroe, thanks for the heads-up on the width & tire size...I'll double check what setting that machine was on.
Rusty, as 3R states, it does look like the M7060 will offer the 12/12 as an option...or check this out .....maybe I'll convince the lil lady to move to nz so we can get one in an M40 version?? haha

case245, thanks for that info. i'm actually not TOO worried about rolling it...it just felt like it was going going to. (not the best feeling in the world).
one more point on the R4s. With un-loaded tires and no weight, i've tackled some VERY steep hills, bushhogging with the L4330, 6' rotary without traction issues. I only run on those hills when the ground is firm and the dew is off.
