Mark, sorry to hear of your illness /w3tcompact/icons/frown.gif, very good to have you back. While you were gone, if Del doesn't talk me out of it, I have decided to get a real Backhoe (or small excavator).
Paccorti (fellow NH owner, Yeh!), just FWIW per the manual:
My NH SupahBoomah has hydrostatically operated disk rear brakes with coaxial pistons and independent hydraulic circuits for each side in the rear. Everything runs in the hydraulic fluid. Fronts are similarly described except one circuit and only engaged when the brake pedals are hooked together (ie, definitely for road driving, but I keep mine together most all the time).

My parking brake is also disk, completely independent of the rear brakes, connected to the pinion shaft /w3tcompact/icons/cool.gif.
Not sure how this compares to Kubota and JD, but thought I would post the info. I usually do not have to "push" real hard, but my machine weights over 8K with the loader and bucket (MT tires at present) so momentum is a factor /w3tcompact/icons/smile.gif.
