Did not know about the float on the lift. If the electric does not have a float it would be hard to use on about anything. Not really wanting the tiller on the rear due to cost. I have a horse tiller that does fine in the garden. I may just abandon the lift project and just use the original manual lift anyway. I have an extra cradle to make a lift assist with and a set of springs.
The Electric system does not need "float".
Float is mechanically built into every GRAVELY attachment except the rear tiller and the center mount blade - don't know that you want float on the center mount blade.
The slide rod that lifts the mower or snow doser allows float.
The two piece push rod that lifts front attachments provides float.
The whole point of the GRAVELY system is that with hydraulic or manual lift, the attachments float by design, the lift does just that - it lifts them. They are all designed for the lift to be ALL the way down during operation.
With the center mount blade down force is desired - it has a sheer pin design on the lift bar.
So the rear tiller remains the only attachment that potentially benefits from float. The rear tiller was discontinued before the electric/hydraulic system was introduced on the G series.
I have never used a rear tiller, so I will not comment on how necessary float is to its operation, but I know there are several members of this forum with rear tillers on electric lift G tractors and they have said it works fine with no float.
After 1994 GRAVELY recommended front mounted plowing or tilling for the riders.
Big advantage to the electric lift - it works without the engine running.
Biggest drawback - the cost of the unit if it fails.
I will take a few pictures when I can.
