double-action 3-point hydraulic

[valere161]

Hello,
Which tractors are featured with double-action 3-point hydraulic?
The few tractors I worked with were only raising the implement. When the hydraulic is lowered, the force that push the implement toward the ground is limited to its own weight.
What if I need to transfer tractor weight to the implement for some work?
Thanks,
JD

Very few have 3PH downforce.

What are you wanting it for? Whats the application?

For example, I have a 5' offset disc harrow adjusted and modified to use as a hiller. I want to get a more agressive effect.

can you add weight to the harrow framework?

It can be done, requires a modification of the top mounting bracket and suitable attachment points on the implement to be pushed down. I have a working unit on my L4350 and it is very handy for what I use it for. Currently I am working on another adaptation of the same principal on my B7800. I have the brackets but just don't have the time right now.

Downforce was one of the benefits of the Farmall fast hitch that we had on my Dad's 200 back when I was a boy. The 3 pt has become almost universal but there were things that the fast hitch did better. I remember Dad disking with that tractor and pushing the disk down hard enough to raise the rear tires off the ground! He'd back off a bit on the drawbar downforce and proceed to chew up some ground!
