I just found a review that stated: Going Downhill – engine braking. The Ryobi RM480 will pick up speed going down any slope. (freewheel) It can be quite a surprise the first time you go into a ditch with it! It does not have natural engine/transmission braking like your gas-powered riding mower...

I finally used my high school physics training.... A 550 pound Mower + 200 pound driver going down a driveway with a decline of 60 feet dissipates a total energy of 61 kJ (=58 BTU). Let's assume that the disk brake and surrounding metal weighs 1 pound. That metal would heat up from ambient 60...

Rivets, Thanks for the manual! It implies that there are two brakes, which is exactly twice as much as the Craftsman! That might be a good sign. Still no real picture of the actual brake(s).

Hi Bert, Re: going up 38 degree slope. Going up is not the issue. It is going down a 300 ft long driveway - roughly 15 degree slope and 60 ft drop. I used engine braking -- engine in lowest gear_ to no avail. The machine picks up speed and I have no choice but to engage the brakes. The...

Bertsmobile1: thanks for your reply. A few notes: the Craftsman gas mower 2" brakes were simply life-threatening. There was no stopping going down hill, even after maintenance (greased all the links and bearings and a installing new brake path). The maximum hill specification for the Craftsman...
