I'm not an Allis guy, and maybe an AC 8030 isn't a classic, but I could use your experience. I'm helping a neighbour with harvest, and he is an Allis guy. I'm running loads with an AC 8030 with the 20 speed Power Director transmission. Good outfit, gross wight of nearly 40 tons when loaded. But I cannot get the hang of shifting on the roll. I can get rolling on the road but going from 4th to 5th gear in high range low power shift requires the tractor to slow to almost a dead stop before it will go into 5th, then more clutch slipping that I like to do before its fully engaged and then power shift into high. It says on a placard tractor must be stopped before shifting gear levers. Is this just the nature of the beast? Handy unit great puller otherwise. Thanks, Ben

The 7000 series was much better (especially the floor shift models) because they had a foot throttle on them. I would get the load rolling in 3RD gear and have the hand throttle set at 1700 RPM. Put the foot throttle to the floor and govern the engine out. Release the foot throttle and pop it into neutral and when the tach said 1700 it will drop right into 5TH gear !! Then, govern it out and hit your high button. Got to be level running obviously, but it works well. A well lubed T-handle shifter is a must. Anyway, I've made a foot throttle for my brothers 8050 and he can do the same thing. DON"T clash gears !!

It works!I tried it and I can consistently get a clash free rolling shift. Me and the 8030 are now friends. Thanks for the tip!

I have an 8030 2WD power director. I never attempt to shift the 5-speed transmission on the go. It was not designed for that. Yes, starting a load in high range 4th or 5th gear is a challenge with a load. I do run a 300 bu grain cart on my 8030 (it's my biggest tractor) but I run it in low range 3rd gear in my fields and bringing the cart across creeks and up hills to the grain truck to dump.

As mentioned, the 8030 has a multi-disc wet clutch. Where the traditional dry clutch would go on the flywheel is a torque limiter instead. The wet clutch will take abuse as mentioned but if you repeatedly started the heavy load in road gear as mentioned, I'd have to think you are really shortening the clutch disc life. The 6-speed powershift version is better suited for road work like pulling wagons.

The power director transmission on those tractors is a collar shift type. It doesn't take well to shifting while rolling. There's nothing wrong in there, that's just the way it's made. The power director is a wet clutch, designed to take a fair amount of abuse, particularly the low range.
