candyman,

What are you doing that requires down pressure? Can you just add weight to the implement or re-angle the top link?

You could install a TOP-N-TILT...

If you are doing this so you can exert down pressure it is not a good idea to do this. Most 3-point systems are not designed for the added down pressure force and will prematurely fail and cause unsafe situations with the added down force.

i am doing nothing that requires down pressure, but just seems like when you pay that much for a tractor it should have it.

paul, thanks for the link i`ll check it out. i wonder is this something that can be done without going to a dealer.

down pressure, why not.

hard to believe that no one has said here is how i did it. am i the only one that has ever thought about doing this. ??

I can't understand why it would be needed. Adding down pressure would take the weight from the rear wheels. Adjusting the top link can do the job most of time. All my farm tractors had draft control that when useing ground engaging equipment like a plow had some down effect but otherwise it was not needed.

No, your not. I built a 3PH for my MF12H GT many moons ago and used a 2-way cylinder for control, but no float position. It was great for changing tires, but don't even think of trying to control depth of cut. You run out of traction real quick.

With FELs on my 2 larger tractors, I have no problem getting the rear tires off the ground. Lift the front end with bucket down force and put axle stands just in front of the rear tires and relax the down force. Front tires go down, back tires go up. Simple.

The problem with only using the top link to create down pressure is the angle of the implement will change once you extend the top link beyond the lower arms. Yes.. I, too, had thought about rigging up down pressure, but then I realized I can't think of any time I'd use it.

Adjusting your top link longer on most implements will help them dig in better. I have a ripper (like a mini sub-soiler at around 16" deep) that has no trouble digging and often stops me in 4WD Low w/ diff-lock!

Plows and even rear blades (in many cases) respond well to lengthening the top link. I admit I have hung weight off an implement a couple times, but it's certainly not the norm.

Far from the first to consider this option. My Dad built a back blade for a John Deere "G" that had down pressure using a PTO mounted pump and a three point system that hooked to the rear axle. This was around 1950. Worked well but was used only for grading the road and in the barn lots.

I agree with the other posters, set the draft on the implement and don't tear up the three point hitch.

Never had or even seen a tractor with down force on the three point, not even the Ford 8210. it was originally designed so that the implement would pull down all four wheels of the tractor and improve traction compared to trailed implements. Down pressure would completely defeat the object. If a plough or other ground engaging equipment is not penetrating the soil then it isn't set up correctly.

thanks for the replys. i`m still gonna check it out down pressure with free float . seems like there would be a lot of times it would come in handy.

this tractor stuff is all new to me not sure if i`m using the right terminology.

As other sage tractor users have said, totally unnecessary, get the implement adjusted properly and you dont need it. Forcing most implements down only takes weight off the main drive tires and obviously causes loss of traction, I dont see the point as most manufactured implements are designed to use the "natural" draft principle anyways.

Good luck on your endeavor to build a "better" mouse trap though.

Personally, I think either you will end up with zero traction or something will break! I wouldn't even consider such a mod. You are trying to undo all Harry Fergusons hard work.

My old Farmall 460 has downforce, but have only used it with the PHD, but since it came with the 2 point and equipment bar standard, so I had to get a three point conversion kit for the PHD
