[AT] 70 John Deere

[Brian Lesh]

Most old tractors around here had separate system for loader using a pto 
pump.  Then you can use the JD 70 Hyd system for the aftermarket 3 pt.

Sounds like you would need three, one for raise, one for bucket, and one for 3 point. The one for raise would tee to two separate cylinders. If the current valves that you have aren’t too old you may be able to get a third valve of the same brand added to the existing valves.  Then you would only have to run lines to the 3 point and not touch the existing system. Otherwise you would have to buy a new set of valves and reconnect all the existing lines and add lines for the 3 point.

When you want to use the 3 point, close the shut off valve to the bucket cylinder and open the shut off valve to the 3 point cylinder. When you want to use bucket, close the shut off valve to the 3 point cylinder and open the shut off valve to the bucket cylinder. Kind of Rube Goldberg, but it would work and wouldn’t be too combersome as long as you don’t have to switch between the two every hour.
