same as my 976 versatile , she is set at 400hp also , yes you could build kit yourself no problem , pulley for front of crank may be the biggest issue

Hydraulics....
Remember that 1 gpm at 1500 psi requires 1 hp.
So, your shafts, couplers, belt drives, need to be able to transmit that.
855 aux drive engineered for 14? hp
AJ closed system on an old Vers has frame space for belly mount with Gates cog belt off harmonic balancer. Cog belts efficient but require less than 1-2 ° offset.
40+ hp would need 3 B V belts.
Steiger has no room for that.
PTO drive build what you want.
Old Steigers you can rob off charge system or mount off back of tranny.
Just ask

Neighbour rigged an auxiliary diesel powered hydraulic system mounted on the air cart to run the fan and down pressure I believe. Looks slick and allows him to use an older tractor.

Thought of that.
Early air carts had an engine to run the fan but they dusted quickly. Curious to see what he did.

Honestly, I wish I'd traded when had the chance.
Main component renewal more money than payments
