Re: Does an electric hydraulic G series tractor deck have a "Float" position?
Yes, the sound of the pump goes to a higher pitch whine at ether end of the travel. This is normal. Remember I bought my tractor new, so I have considerable experience with the electric hydraulic lift.
The bypass is built into the unit, the high pitch sound IS the bypass working as designed.
With age some seepage is normal, I never worry about it, it takes a LONG time for the fluid to go even a little low.
Again, going back to before the electric hydraulic system, GRAVELY intended the decks and snow dozers to float on the lift rod. The float position on the transmission driven hydraulics was intended more for ground engaging attachments like the rear tiller, which had no other way to float.
Even the snow blowers have the two piece push rod which allows them to float without the hydraulic cylinder or the rock shaft moving. With the electric hydraulic tractors it is important to always run the lift all the way down.
Given a choice, I prefer the electric system, it allow raising and lowering while the engine is off, and the science says it uses less engine hp.
