Toe In-Out, Caster Camber

65 3000. Installed after market PS.

Set up front end per serv. manual specs. for regular OEM tractor. Even with the rear brake applied, when I make a turn, the outer front (3 rib 550-16) tire digs a groove in the ground/grass. Anybody have this type of a problem and have a cure? Otherwise steering is super, no shaking, vibrations, shimmy or any of that. Front end is tight.

My MIL's 3000 will cut a little grove when turning sharp, my 4000SU and 801 both do it, seams like the outside tire turns a little sharper than the inside tire.
Now if that aftermarket kit has it plowing a furrow that's a different story.

Did the aftermarket PS kit include a different PS box? If so, I doubt there's anything you can do about it, as the turning angles of the two tires will be dictated by the gear profiles inside the box.

the geometry is determined by the tie rods, if you did not change those and have the toe in set, nothing is different. The tie rods should point to the center of the rear axle when wheels are straight ahead. This should have come from the manufacturer, and can only change if you have a spindle twisted or tie rod bent.

Is it one of the after market p/s kits that only has a cylinder on one side and comes with new linkage to go across under the nose of the tractor between the two spindles? If so I would follow the instructions that come with the p/s kit to adjust the toe rather then the original service manual for the tractor.

That's what it does.

No hooks to one side only. The other steering arm from the box to the right front tire is removed. A tie rod from the left side is used to control the right tire.

The unit came with it's own steering arms which allow you to use the tie rod. On the drive side, I kept the woodruff key in the spindle to arm interface. On the right side controlled by the tie rod, for some reason I couldn't get things to line up and did not put the key back in that side. Been a couple years now and I forget but I may have had to turn the steering arm to keep it from hitting the side of the wheel on the right side. Regardless, whatever radial error I created in doing that was picked up in the threaded end of the tie rod.

The steering arms that connect to the spindles aren't straight and parallel to the curved front axle like with OEM installations. The left one has 2 arms, one to the side like on OEM for the cylinder to connect from the steering box and the other comes off the rear of it and drops down so that it can connect to the same type arm on the right side via the tie rod.

ON setting to OEM, I set toe in per the manual, measured by comparing the front of the tire (half way up) from the ground to the rear. Difference between the two measurements, tire to tire was something like a quarter inch less on the front side. The threaded end of the tie rod on the right side is where you set up the toe out-in.

Seems to me that once you set it up to get the wheels aligned when straight forward, they should track through the turns.

I think tomorrow or so, busy schedule next few days, but first chance I get I'll check toe in at the full turned positions (fully cw and fully ccw) and see what happens to tracking. Going to bet it changes big time and the next step it to figure out what caused it.

Course it may just be that with the PS, it's so easy to turn that I power through turns whereas on my 2000 which doesn't have PS, I have to work through the turn so it's a slower turn.

Thanks guys for kicking in on this. Will post a follow up when I get some new info.

Update: Gotta make this politically correct so you guys will accept it: My wrenches "misapplied themselves"......you mean YOU messed up?????????

Seriously, Checks proved that the toe in wasn't half an inch it was 2 ? inches. I checked for anything that may have moved out of position and found nothing, meaning "I didn't set it up right" in the first place.

Guess I was overwhelmed by the whole process, mainly getting the steering balanced so that the degree of turn was equal on both sides, and didn't set it right.

Works fine now and steering is smoother and easier......Darn those wrenches. Maybe time for a new set.....yeah right!
