Titus.....I may end up learning something right along side you here but I don't believe our machines ('71 444s) have the "retard position" on our travel levers that is being referenced here. I've read of guys installing mechanisms that allow for it. If we do have the ability to "retard" the system going down hills that would be great. Here's some chatter about ways to install something on our tractors:
Yesterday's Tractor Co. thread.....
Q--"I have a Case 444 that is a great tractor until you come to the slightest grade. It then runs away with itself until you put it in neutral by stepping on the brake or using the speed control lever--- then the wheels lock up. It has gotten to the point of being too dangerous to use on the hills since I moved here. Is this common for these----like non exsitent braking or hydro control going down a grade? Is there a solution for this other than finding another tractor?"
A--This is normal if you leave the travel lever in the full travel position. If you want it to stay a constant speed then you can either get the flow control valve kit or motor brake valve kit from an Ingersoll dealer and pay some pretty hefty bucks but with minimal mods or go to a hydraulic shop and get a hydraulic motor brake valve and plumb into the drive circuit. I just place the lever on my later model 446 in the retard position prior to cresting the hill.
Another comment from the same thread stated...."You are supposed to just use the speed control taking it into reverse slowly to slow down going down hill." I'd be curious to hear from our guys whether this is correct. Not been something I'm accustomed to doing.
