Boosting The Hydraulic Power Of Older Tractors

Boosting the hydraulic power of older tractors TRACTORS Made-It-Myself 17-3-34 Several years ago you published an idea for boosting the hydraulic power of older tractors. Could you repeat that information? (Red Escamilla, Normangee, Texas) Our 1985 report (Vol. 9, No. 1) featured A.G. McConnell, Danville, Kent., who owned a 560 Farmall gastracor with about 1,800 psi hydraulic pressure. He wanted to run a Hesston baler that required at least 2,000 psi to operate. He used the large area of one piston to push against smaller pistons, increasing the per unit area pressure on the small pistons. He hooked the auxiliary cylinder up between the pressure side of the tractor hydraulics and the two smaller cylinders on the baler. The volume of the piston rod end on the larger cylinder must be slightly larger than the volume of the two smaller baler cylinders. He hooked the feed hose on the baler to the piston rod end of the new cylinder and the return hose on the baler to the return on the tractor. The opposite end of the new cylinder hooks directly to the pressure side on the tractor. The piston rod end of the new cylinder had to be purged of air and somefluid added. McConnell reported that when he hooked up all the hoses and went to the field, everything worked fine.
