I've been reading through the manuals to learn as much as I can about my 444. I also looked through skad's of videos featuring Case/Ingersoll tractors. There's one question I haven't really found an answer for though. When you reduce the ground speed with the hydrive, does it reduce the amount of power to the rear wheels?  For example; If I'm pulling a heavy load, would the tractor pull better by advancing the hydrive lever further forward, or let it creep?

Can't explain this real good on my phone right now , but you always have the same amount of power to the rear end, think of it like a hyd,cylinder on a lift. You can go slow or fast with the lift but always have the same lifting power. Hydraulic fluid doesn't compress all you all changing is the velocity that is comming through after the pump

When you back off on the hydro (slow down) you should be able to pull more. Think of it as shifting down. 

This is the way it has worked for me anyhow. 

Another advantage to the hydro is that you should very seldom need to use your brakes. The braking action of the hydro is very effective.

  Speed shouldn't affect power until speed and load reach the point of engine overload and engine RPM starts dropping.
