In a nutshell . . . both, and a whole bunch of extra tubes and hoses.

As you power down, the fluid in the opposite end of the cylinder needs to return back to the system through the valve.

Doable . . . yes, practical . . . probably not. But then again, where there's a will, there's a way.

Steve,
You will want to check out the linkage on the 3-point hitch before you go changing around the hydraulics. If I remember correctly, the 3-point arms are setup to float, so forcing the hydraulics down may still not put down pressure on the arms. Most of the tractors are set up this way, so that you cannot tear the back of the tractor up.

On my new tractor, I add 40-pound suitcase weights to the back blade, whenever I want to really cut with it. The extra 80 pounds out on the blade frame really makes a difference, but the tractor can still lift it fine.

Wow, drag bikes. There's some fun. I'll never forget when I used to race my 89 Mustang, there was a guy on a stretched Ninja that would carry the front wheel all the way down the 1/4 mile. You would see the puff of smoke off the front tire when he finally crossed the line and let off the throttle. That's some SERIOUS racing!!!

If you're ever headed up here, give me a shout. I'm literally about a mile from FBG, over on Long Rd.

There's a reason why the 3pt hitches don't have down pressure, when you put down pressure on the attachment your taking away traction from the rear tires. Your actually lifting the rear tires with the attachment, all it takes is a little lift. On uneven ground it only gets worse. I was going to try this too until i thought about it. If you had a perfectly flat field and a larger 4x4 tractor then having down pressure may work when plowing dirt. But they also have trailer wheels adjusting the height / depth of the attachment too.
