Just played around with my new mower yesterday and notice something strang about the speed of the mower.. The last ferris i owned had the joystick type speed control where you just pushed it all the way forward and you reached your top speed. But with my new mower i push the forward control lever forward all the way and it doesnt reach its top speed. I then have to push down both speed override controls to get it up to top speed and hold those two levers with my thumb to keep it at that speed. Am i missing something here or is this just the way the new ferris mowers are???
