I have a 44 in. model labeled with Farm King decals with slip clutch on a Kubota B7100HST.
It's been badly beeten around on 50 year old very rocky sod. Broken many tines and have worn out three chains as well as breaking the chain a few times.
For the conditions it was used in I have no complaints.
In Canada it may be painted orange and listed as a Kubota rotatiller.
