JD R hydraulic cylinder/holder

Anyone have any pictures of how they are supposed to fit on the tractor?

Also, would a hyd lift plow come with a cylinder? Or are they specific to the tractor?

Thanks

The cylinder holder on the R Dad had for a short time bolted to the step on the right side. Pull type plow probably won't come with a hyd cylinder but it might. He got a cylinder, with the tractor and the 4-14 plow, but I think it was extra, bet it weighed close to 100#, 4x8 2-way with the heaviest clumbsiest stroke control mechanism ever, two BIG steel bars probably a foot long, Huge heavy casting that stopped the clevis on the rod, and you pinned the rods about every inch. A 4020 cylinder is just as strong, lighter, easier to find, and infinite stroke settings.

Yes but the cylinder from an R may be for a low pressure system where the 4020 has a higher hydraulic pressure. It will work, just won't lift as much. By the way, don't use an older cylinder on a newer tractor....it may split with repeated use like mine did....

Yes, R was lower psi than the new generation tractors, but in the case of Our R, didn't take much psi to lift an IH #8 3-14 plow out of the ground. The H's, M's, and Super M-TA all had 800-850 psi hydraulics. SM-TA was probably higher like 1200+, not sure what R hyd psi was but should lift anything it could pull with the New Generation cylinder, I think the cylinder we had for the 4010 was a 3-1/2" bore.

Yes, somebody should buy a short line 2500-3000 psi cylinder for his new generation tractor before using those old fashioned and HEAVY dated cylinders.

IH broke ASAE standards by using small bore, like 1-1/4" or 1-3/4" bore by 16 inch stroke cylinders on lots of mounted implements. All of Dad's mounted IH cultivators used that size cylinders, had one that size on our Oliver sickle mower we ran with the '39 H, also raised the 2M-E mounted corn picker with one. Last couple years Dad farmed him and the neighbor picked and hauled loads of ear corn to the cribs and raised the wagons with the picker tractors, those old small bore cylinders withstood much higher psi than they were rated for. Pick all day into the same wagon, get 10-12 loads in half mile rows. With two pickers the 80 acres was done in two days.
