Chipper Help Super Apache Chipper

[DLMaine01]

I am going to look at a Super Apache Chipper. Owner says 3" capacity and is running it with a "43" hp Kubota. I will assume a 4330 or 4310. I would run on a Kubota M4900. I am hopeing its Cat I.
My main use is grinding sweet corn culls and stalks for cows. Plus a small amount of 3" or less brush chipping.
Anyone have one of these? How do they hold up?
Thanks for any info!!!
Dave
