i picked one an old Waldon 5000 loader and have a few questions. what type of drive is used in it (to power the wheels)? i know it is some type of hydraulic drive, but i'm not familiar with anything like this, having owned vehicles with "normal" transmissions previously. also, if anyone is familiar with these, how are they when running up inclines? i'm talking maybe 10 or 15 grade, not 45 degrees. it seems to run great on the level, but especially in high range it isn't too happy going up a small hill behind my garage. also, anyone know of a source for an operator's manual?
