The Wil-Rich 1500 is an older model. It is intended to be used as a seedbed finisher and to cut down crop debris and stalks. It is programmed as a mulcher in-game. As always, please report any problems to me, and I'll do my best to get them resolved as quickly as possible.
NOTE: I am already aware that when it is disconnected, it sets in the ground. I'm trying to address that and will have an update shortly.

Thanks to OutLawCreek
