I know I sure wish my rubi had disks all the way around, just because when im pulling heavy loads of gravel (1,000lbs) with dual trailers up steep hills for trail maintence with 2 bags of concrete on the front rack for traction those drums sure suck, i stand on the rear's and squeese both levers and it barly holds it from rolling backwards!

 

H ave you tried dragging your feet??

 

Now, there's a situation the lawyers will have to add to the owner's manual in the "Don't do this" section.

Even with the 4 wheel disks I find the 35 degree downhills exciting to say the least when I have a full trailer full of wet firewood. Keeps you on your toes.
