Does anybody know if a 1989 9180 case ih has enough hyd to run a seed hawk
I did a similar piston pump upgrade to a Case 9280. It increased my flow 31-32 gpm on a dedicated system for running fans and works just great. It upgrades an older tractor that may be in perfect condition, other than the hydraulics are not large enough flow for new drills. I used the tractor on FC SC380 VR tank and Bourgault 6450 with dual fans and it handles everything very easy - capacity to spare even at 15-1600 engine rpm. The fans do not vary more than 10-20 rpm under any condition all season. It also runs much cooler than the original 27 gpm system because we sized all the fan plumbing to 1" and is very low restriction. I would just go to a major hydraulic supplier and get some quotes. There are several that I could recommend in the Edmonton area. PS Drive your new pump off the pto outlet on the back of the PS transmission and you can run whatever you want.I put a 32 gpm on a 9380 with a 60' seed master, very similar, it was maxed out, when I put it in the ground I had to be careful or I would plug hoses
