4052R down pressure

/ 4052R down pressure #41  
Piston,
Personally, I think the feature may hold merit in certain situations. Like trying to penetrate hard clay soil and the implement just rides on the surface without making sufficient penetration. In such a scenario, it wouldn't affect traction, because the implement would just skim along the surface of the soil.When I first mentioned this feature in a post, I got a few responses that questioned the merit and feasibility. Interested in what you find out in terms of the details.

John, that is exactly when it affects traction, you have removed 450lbs of weight from the rear tires because the implement will not go into the ground.

Most people consider primary function of the Three Point Hitch is to connect implements to the tractor.

Connection could be done, and was done, more simply with a pin hitch before the Three Point Hitch was invented during the period 1920 - 1935.

The key design feature of the Three Point Hitch is its WEIGHT TRANSFER to tractor tires, improving tire traction. {Other Three Point Hitch design constituents: adjustability, hydraulic lift, draft control.}

(No such thing as Industrial Tires before the Three Point Hitch. Industrial Tires did not become a big factor until 4-WD was combined with Three Point Hitch.)

Prior to Harry Ferguson's invention of the Three Point Hitch "light" tractors were six tons and implements were connected by some variation of a pin hitch. "Light", six ton tractors could not pull very effective plows because "light" pin hitch tractors lost traction.

Three Point Hitch down pressure can only work when a tractor is STATIONARY, i.e.: post hole auger.

I guess having down pressure on the loader bucket isn't useful unless the tractor is stationary? Hardly.

All modern construction tractors (skip loaders) are equipped with hydraulic down pressure. I'm pretty sure the feature isn't just for changing tires. You'd be hard pressed to find one augering holes since a stand alone hydraulic PTO is a rarely ordered option on all of them.

Just because you don't know don't make it so.

This is getting interesting, to be sure....I wish we had some way of testing and measuring results to find out. I wonder if "Everything Attachments" could render an opinion, or someone who we recognize as knowing a bit more than the rest of us. Not that posters on here aren't knowledgeable; they are.

I think we need a 3rd party to give an independent opinion. What say yee ?

So far, this thread has only been about down pressure on the tractor Three Point Hitch.

Front end loaders, which are NOT mounted on a Three Point Hitch, work under entirely different parameters.

I've watched Ted and Peanut operate enough to know that they should stick to their day job. :laughing: I'll stick to my day job too.

Jeff, I would agree. I think we're talking a little difference in physics. Admittedly when the bucket is full and lifted, weight and pressure is applied to the front end, simultaneously, traction and pressure on the backend (wheels) is reduced. Having said that, I still don't know what the correct answer is to our discussion riddle.

There is no riddle. But...all you backyard operators keep having one anyway.

MtnViewRanch, aka Brian @ Fit Rite Hydraulics, is one of T-B-N's most knowledgeable posters. As this "down force" thread is about hydraulic pressure potentially applied to the Three Point Hitch, and Brian is a hydraulic pro, I think Brian is the expert.

In the past, Brian has differed with me on several posts. On reflection I had to acknowledge that he was correct EVERY TIME. Now, having rubbed up thicker seat calluses, I have become a modest tractor genius too.

You 'n Agnes should visit us in Florida, when you thaw out.

I could use some Florida right now.

That was funny John:laughing:

Merry Christmas everyone, thought I would check up on all of you.

Does anyone have a good photo of the rear 3 point area with the downforce option? I would think the tractor could hydraulically operate both top-n-tilt and downforce but maybe there isn't enough real estate back there.

The case 570 Lxt-Nxt have down pressure for boxblades they do not come standard with pto. Admiitly it will drop traction to rear tires that is where experience comes in you don't have to fully engage the full down pressure just enough to get the job done. John deere brochures say for post hole digger and boxblades. I'm not a hydraulic genus and really don't need to be one to operate a boxblade. I just want to know why I can't get it with top and tilt. Don't over think the over thinkers.
