So the picture on the left is one I found on a website and the one on the right is a modified version of what I plan to do, can you see any problems with it?
Thanks

Ackerman is right. Direct steer won't work. Need another connecting spot on your king pin for drag link. Should be a good diagram on here somewhere.

Oh, I'm fine. I just completely fail to understand what's supposed to be wrong there. Y'all gotta remember- I do go karts. Go karts= direct steer. I factor in Ackermann, KPI and caster when I do them. But unless I wasn't paying full attention, I didn't see anything wrong there.

They are commenting on the black lines (linkages). All linkages should when possible be 90 degrees on another. That way you get equal throw left and right, right? tongue

The diagram works fine in the original configuration. Basic go kart stuff. I'm stumped here. I see nothing wrong.

What, the first diagram OP drew? There's a lot wrong with that one. Steering backwards, don't get full motion range.

I guess that's a matter of perspective. If you're silly enough to take it as a scale technical drawing... Maybe. Maybe not.

Okay, finally got some time to post what I think needs to happen.


On left, is a simplified version of what Doc posted, what I would call go-kart/ATV steering.  Two tie rods connected to one or two pitman arms in the middle.  Works great, but usually we have an engine in the way.

On the right is what works for front engine mowers.  Steering column is not shown, because it is straight up and down for this simple drawing.  It uses an extra connection to the spindles to get the steering hooked up.
