Ted:
That was exactly my initial approach. Basically steering with the drive wheels. However, to do that, the front wheels must "caster". When I decided to add a small front end loader to the tractor's design, it meant that I couldn't use the simple castering front wheels. And that has...
Yeah, no doubt, steering has to remain the priority control. I was going to put a small front-end loader on this thing and I don't think that castering front wheels would work with a bucket. Still, complexity caused by front steering is making it look like a 'bridge too far'. Proportional flow...
Well, yes, but then I lose two things. One, the benefit of having two driven wheels. If either one spins, your stuck. Also, I had intended to use them as brakes by having a blocked center on my spool valve. Something just occurred to me. If I use a double ended cylinder for the steering...
Hello all:
I'm tinkering with how to allow slip between two hydraulic wheel motors used to propel a small tractor. Originally, I was going to control each motor with a dedicated double acting spool valve to provide both motive power and steering. However, the design evolved to use dual wheel...
