This is a Case IH Turbo Till. These are becoming more and more popular in the US because of the amazing cultivating ability with just a single pass.
The disk is from ModHoster, and Surci (the original uploader) gave me permission to release this edit.
I have added the crumblers, as well as the script to make them turn, and have re-textured this to more modern Case IH colors.
This is just a plain cultivator, no safemode, very simple to use.
V- to raise and lower
X- to fold/unfold
