D19 Allis hyd ? on using jd 7000 planter

I can't answer for a D19 but I thought I would pull my IH grain drill with my D17 one year. The grain drill has hyd lift and markers. A sequence valve operates the markers. Two rounds of that was enough. Slower than death. A 7000 planter has cylinders in the tube that have a cable latch system(make sure you pull it out once in a while and oil it). If the D19 is similar to the D17 it will be slow. Not enough volume.

D-19 is low pressure (2000-2200 psi) and will work, but poorly. GPM flow is pretty low and when you push the foot clutch in, the hydraulics are dead. A front crankshaft driven pump of 10 to 12 GPM using your existing valves would work pretty good.

The D-19 and 100 series were the same 2,000 to 2,200 psi.

Front pumps on a D-19 have been added to actually make a decent "live" hydraulic system. Everything newer and larger than a D-17 series 4 has "live" hydraulics.

High pressure/low volume systems used less fuel. Low pressure/high volume systems use more fuel and require more expensive/larger diameter cylinders to get the work done. How many days of the tractor use year did the hydraulic system even get used ??  On some Deere 2-bangers they even had a hydraulic disconnect to help on fuel use when no hydraulics were needed. By the early 1960's everyone was attempting to "standardize " hydraulic system pressures so a customer could buy with confidence any brand of tractor and it would work with any brand of implement. So, 2,000 PSI was somewhere in-between the AC 3400 psi system and an M Farmall at 800 psi.  AC not having standard equipment 2-way hydraulics was a negative, as was the fact that the hydraulic pump required using the hand clutch.

Thanks for the reply Doc 

We pulled a 4 row wide not a narrow but I did pull a 4 row narrow Allis 330 with the 190XT.

D-19 wheelbase is 103 inches long while a 180/185 is 99 inches. D-19 overall length is 144 inches while a 180/185 is 158 inches. This is a little confusing, but the 3-point hitch draft arms sticking out causes this number to be more while the D-19 was a snap-coupler chassis.

I had two neighbors that pulled 8-38" 7000 Deere planters with gas D-17 SIV's. Both tractors had dual wheels and one of the planters had dry fertilizer on it. Both operators said high second gear and 3/4 to full throttle.

FREED, It's a Series III Landhandler. It belongs to one of my brothers. I now pull a 6 row White 5100 with that XT. Keeps the tractor limber vs sitting in his shed for years on end. It is a great tractor.
