</font><font color="blue" class="small">( My mistake. It is Float and not draft. What is float or is this way to obvious? )</font>
To try to make it really clear. The joystick has a four-way operation. If one pushes the stick all the way forward, the stick will lock into float, the loader bucket will go to the ground and will follow the contour of the ground as you back drag the loader. For example, you just dug a little dirt up while removing a small tree and now you want to cover the hole up. You curl the bucket cutting edge down to where when you drop the bucket, it will "scrape" the dirt as you back up. If you don't put it in float, and the tractor goes over a hump, the bucket will rise and fall with the tractor. In float, it will just stay on the ground and follow the contour, pulling the dirt into the hole. It's useful for other things, but that's what I use it for the most. Same story on the 3PT hitch with position control as Beenthere mentioned. Drop the implement all the way to the ground, the lever at it's most forward position, the implement will follow the contours of the terrain. Don't worry about obvious, if you're new to tractors, there's very little that is obvious. John
