What would be the usage?
If for a snow blower I have seen many guys use the rear PTO+2 gear boxes and a long shaft that runs full lenght to the front to drive a standard snow blower.
(in fact I have a factory made one that I don't use as I prefer rear blower)
If for a hydraulic pump, then you could consider taking the drive off of your crankshaft pulley.
On my tractor I have 2 pumps, the factory origional for the PTO lift and I added a larger capacity pump to power my FEL.
Have been operating that way for at least 5 yrs now and makes loader operations quite rapid with the higher capacity pump.
But note that my owner and shop manual did show this as an option except that factory installation had an electric clutch. While the manual did not specify actual usages I can only presume a front blower might have been the plan. I did order the actual pully part from my dealer and worked from there.
