Ran out to the barn and tried it. Had to push hard, but it does indeed go up another notch.Thanks for the tips on engaging it off the ground until getting the hang of it.
When you get skilled with float you can use it to scoop up material for example a dile of dirt, stone or gravel that you need to move from on area to another.
1) As you drop the bucket down engage float just prior to the bucket hitting the ground [MAKE SURE THE BUCKET IS EITHER LEVEL OR CURLED UP A BIT. IF you engage float with the bucket curled down you will dig in and things can get nasty]
2) once the bucket is on the ground and level now you can pop the joystick back [disengaging float] and you have now quickily and accurately set your bucket level to the ground.
3) As the bucket enters into the pile of material you can now gradually raise the bucket.
If you do not use float in this process you risk pushing the bucket too far down and potentially taking presure off your front wheels
I have used six tractors over the years from 22 to 80 hp as well as a backhoe and never felt I needed to use "float", but will give it a try, thanks.
