Toe-In

[Ranch_Hand_Supp]

Camber not adjustable? What about motor graders, they can adjust their steering wheels from vertical to almost parallel with the ground (to offset the torque/side loading of the blade). But I guess it's "technically" not a tractor.

I don't have any mechanical experience
with motor graders but I have noticed they are built to adjust from the seat so they can stay on the side of a hill/bank and yes I was refering to tractors.

Caster is one of the settings that makes the front wheels straighten back up after turning.

Dirt does not wear tires as quick as a hard service will but, when alignment specs get out it will put extra un-needed stress on the steering etc and speeds up wear as well as how it handles.

Here is why you need to tilt the tires on a motor grader.
When you are pulling a windrow, the end of the blade that is closest to the rear tires is called the heel of the blade. The end that is closest to the front wheel is called the toe of the blade. If you have a large windrow, the force of the soil on the blade wants to push the grader away from the windrow. If you tilt the top of the front tires toward the heel of the blade, it will pull the grader into the windrow so you can maintain a straight line.
On a blade like the Cat 14G or 14H, you can shift the blade all the way out to the side and rotate the blade so it is 90 degrees to the ground. This lets you grade a vertical slope if you like. When grading slopes this way, you can articulate the front of the grader and put your front wheels up on the slope and tilt them towrds the slope. This lets the edge of the tires dig in to keep traction.
If you are traveling in a straight line and tilt the top of the front tires to the right, the grader will go right. Tilt left and you go left. Because it takes 40 acres to turn around a grader, we use the tilt of the tires to help turn around in a shorter radius.

The main reason vehicles have negitive camber is because when the top of the spindle is tilted in, it puts more of the load of the front axle on the larger inner wheel bearing. It works the same way as if you would put reversed wheels on a vehicle it puts more stress on the wheel bearings.
This is the reason you are not supposed to reverse the rims on the front axle of most tractors.

I meant to say POSITIVE camber instead of NEGITIVE camber.
Please excuse the error.

One thing I didn't see mentioned about toe in is if you have to much or to little it scuffs the grass a lot more. Mine was about 1/2" toed in and when turning sharp with the RFM one front wheel would scuff the grass. I reset the toe close to zero and now it doesn't make a mark.

Is that in 2WD or 4WD?

That is in 2wd . I don't use 4WD unless I need it

...On a tractor, it takes a HECK of a whack to get out of adjustment. Just look at the size of the bars and compare to your car. The tractor is larger, but hits holes at a much lower speed.

Last year I was carrying a full bucket of rocks when I decided to take a short cut over a "rotten log". Turns out the log was far from rotten and I bent my steering linkage in a big way. I was able to remove it and hammer it out without too much trouble. They will bend under load!

Sounds like you inadvertently gave it a HECK of a whack !
