Compressor run-time probably depends on your row length. We talked about the JD engine compressor also. But, I thought it was more like a $5K option. If you trade the tractor, no one really wants your compressor setup....around here. Tractor would still be filling tank on planter just like the electric compressor, I'd guess.

Again, I "think" the TC clutch & JD air bags (fairly popular around here) could both be powered by the same $200 extra-HD compressor carried ON the planter.
