Amerind Mckissim 810a chipper re-powering

[Whenu]

Hi all, I have acquired a chipper/mulcher as above.
It is fitted with a 3 point linkage and I am looking at putting on a frame with a motor.
What size motor (HP) would I be looking for?
I may have access to a 12 horse Kohler.
Cheers

Ps, the title should read McKissic.

pto unit - 12hp is not going to cut it need about double to be worth while. I have 20hp and have to wait for it once in awhile.

Thanks Blades, got in contact with the factory and after sending the s/no. and some photos, they reckon it should need about 10 horses, cheers.
