784 draft and down pressure

Gotta politely disagree with my friends here just a little bit.

The draft control is a mechanism that is designed to maintain a steady "pull" on the tractor when used with below ground implements, most commonly the plow, as Cowman says.

It is built in such a way that it is continually sensing the tug of the implement, then changing the depth of the hitch thru differing soil types by varying/cycling it's own operating height in and out of the ground to keep a steady load on the tractor.

It's effect "seems to be" better traction, but actually, it is more of a "lighter load" that the tractor is subjected to because the implement is being lifted out of the suck.

The hitch is continually going up and down with it’s lift or drop depending on how tough the pull is at any one given time. Maintaining a uniform depth is not one of it's strong features; exactly the opposite is true, as the hitch is always being lifted, or it is being dropped.

The hitch height never stays constant or "static", but the load against the hitch is continually held steady.

The 784 does not have down pressure on 3pt. Only the older 2pt or 3 pt conversion hitch tractors had down pressure.

Re post hole auger, usually the reason for it not digging in the ground is the auger tips are worn out. On most models there are replaceable steel tips/points that start the screw action into the ground, if these tips become worn or broken then the auger will not screw into the ground. Works on the same principle as the old wood augers that were used before the twist drill was invented. Another tip, if you have heavy clay soil don't let the auger down more than 6" inches at a time without lifting it up to clean out the clay or it will drill down to the depth that the auger will be stuck in the hole and the only way out is to disconnect the PTO shaft and put a large pipe wrench on the auger shaft and turn it backwards so it screws itself out of the hole.

Hope this helps
