yes your absolutely correct, sometimes we expect a hydro to run like a gear driven trans. Running the engine at normal rpms helps. I expect some decline in speed. Like any hydro a little more pedal or in this case lever going up hills.
Im hearing a bit of hydro chatter. After talking to some hyraulic hydro-tranny experts(really) they have assured me that my hydro will last another 40 years with normal maintenance. However there is some hydro "chatter as he calls it and that has to do with slipper wear and as they called it slip stick. Im fortunate enough to have a brother who has a degree in hydraulics and has worked with hydraulics in the automotive field( convertible actuating systems Lift mechanisms and now military hydro static applications which is way beyond my comprehension).
He has expressed the fact that when "tweaking" a hydro for the perfect balance it is not an easy task, when you change one variable it affects another.
Hes been working on neutral issues with hydros with a certain government vehicle for six months. Imagine having a hydro that has to maintain speed measure torque and adjust accordingly to inclines, declins weight and speed. all this with apparent seemlessness. I have a spare hydro and the thought of just seeing what if any difference there is. I think that can wait. I need to work onthe steering first.
question on steering effort? will a spindle upgrade help with this. Im not a small man and am strong like bull. but the wife isnt(whew) and she would like to mow the lawn for me occasionally, however she does note it takes a bit more to steer than our other lawn tractors. Weight alone explains most of it and it steers way better than my brother and fathers green and yellow 212.
