Sssssshhh! He says he knows what he's doing, DL.
Lol, never said that. No way, no how, Rich
New guy here,
Looks like a fun build, can't weight to see it finished.
And I also am wondering about the lost of steering angle, maybe on a tractor it won't matter but.....
It's not that the axles are parallel to the ground when pointed straight, it's that as they are turned, the axis they are turned about is tilted the wrong direction. When stock, that axis is tilted in at the top, causing the axle to lift as it is turned, which (I believe) helps keep the tire geometry correct with the ground, and provides a centering force, ie, the axles/wheels will naturally go to a centered position.
With the axle rotation axis tilted out, this natural centering force/action will not happen, and in fact it will want to go to full turn, and what the tire geometry will be I don't know. But it can't be good/right.
Appreciate the input, Dan. And as far as this backyard engineer can figure, you're right. I'm figuring if the issue is too pronounced I can make the spindles neutral, either through heating and bending on the Diacro or just cutting and re-welding. What I'm thinking will be the case is due to the reduced rear tire size, top speed will be reduced, and since this is pretty much rolling art, I think the real world affect will be minimal. Either way, I should have some definitive feedback within 3 or 4 years. Stay tuned
