pto hp

what the max hp used on pto  with 13/4 shaft at 1000 rpm.

is their larger shafts on big tractors.

Not an expert but I think above 200hp they get into the bigger pto shafts    http://www.tractordata.com/articles/technical/tractor-pto-types.html

Wit three different tractors, I've never gotten over 960 PRM, even at full throttle on the tractors and I have both the big and small  shafts.
