It is having the exact same behaviour. Back wheels are losing contact with the ground, and the caster wheels just move it around when they are the only thing that can reach the ground.

Did some messing around, this seems to have worked for the area I am testing.

Main section wheels:

<physics restLoad="4.6" repr="0>0|2|3|1" radius="0.41" forcePointRatio="0.3" frictionScale="2.0" initialCompression="60" suspTravel="0.5" spring="60" damper="50" yOffset="0.095" supportsWheelSink="false"/>

Section wheels:

<physics restLoad="2.6" repr="1>0|1|1|1" radius="0.41" forcePointRatio="0.3" frictionScale="1.0" initialCompression="60" suspTravel="0.5" spring="60" damper="50" yOffset="0.095" supportsWheelSink="false"/>

Caster wheels:

<physics restLoad="2.6" repr="1>0|2"  driveNode="1>0|2|1"  forcePointRatio="0.5" yOffset="0.045" frictionScale="0" radius="0.16" width="1.25" mass="0.25" initialCompression="40" suspTravel="0.6" spring="55" damper="50" rotationDamping="0.4" brakeFactor="0" versatileYRot="true" supportsWheelSink="false"/>

I appreciate you testing that and reporting back so thoroughly .  I had scaled the gauge wheels down, reduced their diameter, then softened the main and wing wheel’s suspension and tried to level the entire cultivator.  I really struggled to get the tail down due to the set height of the gauge wheels.  I honestly might throw those parts in blender and “adjust” the caster arms up so we can fix this properly.  IRL it would be an easy adjustment.  Heck maybe I’ll put them all on mouse control and you can adjust them for the tractor you are using.

Okay.  I discovered that what was happening is the cultivator depending on the terrain would fall into a scenario where it was riding on the collisions for the harrow on the back and none of the actual wheels were truly touching.  Those don’t have any friction with the ground which is why it would slide away as if it was on ice.  SO first of all, I worked in a self leveling hitch functionality that it should have had all along.  This is limited to the fold/unfold raise/lower animations.  Additionally, I added the ability for the harrows to overcome  the “spring” downforce and flex over a much broader range of terrain.  I kept my wheel suspension settings and further refined the diameter of the gauge wheels to allow for a smooth ride on level ground.  This should solve all your problems.   The download link in the previous post has been updated if you’d like to test it again and regardless, I’ll update the main page and link in a few days if you don’t report back any issues.  Thanks!

Everything perfect so far. No sliding around on the dips or the edges of the field, work area is 100% perfect.
