Pull from the front or the rear?

[CalG]

If you look at from the perspective of a two wheeled tractor, it's fairly evident what mechanisms are at work.

Hook up below the rear wheel axle, Use as long a hitch bar as will support the load.

Think of it, if you wanted to "lever" the front of a tractor down from behind the rear end, What arrangement would you use?

Me? I would use a stout rigid bar sticking out the back, pulling UP.

A couple posts above suggest using a drawbar that is as long as possible. I'm wondering what the logic is behind "as long as possible". An extremely long drawbar could actually move the line of pull above the rear axle centerline.

The drawbar hole is supposed to be 14" from the PTO shaft on 540 rpm PTOs. I think that's the standard.

How could it do that? It's fixed below the axle.

There are a fair number of dead tractor drivers that would dispute your theoretical wandering if they could.

They can dispute it all they want, but there's probably a reason they died. This was purely theoretical, in case they're complaining; I've yet to see a tire that won't spin, chain that won't break, a permanently stuck object (talk to Archimedes about moving the world), or a tranny or engine that won't break...

Let me clarify. People have been killed, lots of them, in rear rollovers that happened without any parts failures in exactly the manner your theoretical analysis says can稚 happen. Others have been luckier and escaped death. You are entitled to your opinion, you just can稚 force your opinion to erase fact.

I agree that the rear drawbar is best. The 3 point is a poor choice. The front is OK in some situations. If you are moving a wagon, You will be able to control it much easier if hooked to the front. Weight and situation come into play. I would not be very concerned pulling an 500lb log with a 4000lb tractor on level ground. Pulling a loaded trailer or wagon on a wet hillside no matter how you hook it can get scary in a hurry.

Well duh, the "theoretical analysis" relied on nothing at all breaking, which is why it remains purely theoretical.
Nobody takes such things seriously, except fools and philosophers.

Good reason not to take your keyboard diarrhea seriously.

The way I was shown was there's the draw bar under the tractor's rear axle, sometimes also called a swinging drawbar. Then there's the drawbar with the multiple holes in it that goes between the 3pt lift arms called the 3pt drawbar, or spreader drawbar. I was told to not pull from that 3pt drawbar, only the drawbar under the axle.

Anywho, let's be careful out there....

What is the 3 point drawbar used for if not pulling "something"?

Good question. Towed implements get towed from the drawbar, and 3pt implements get attached to the two lift arms and top-link. I never found a use for the 3 point drawbar when I had a machine with a 3pt hitch.

They are NOT DRAW BARS, They are spreader bars. Made for spacing the lift arms when no attachment is fitted.

That people call them draw bars, or use them for "pulling", is testimony to human ignorance.

Modern tractors with loader don’t flip over backwards. Pulling from the rear of the tractor is what they were made to do. They pull harder that way and it’s easier in the machine.

Why would one need to use a spreader bar if no attachments are fitted and why does it have holes in it if it were not for attaching something.....

Say what now? -Why do you need to space the lift arms when there is no attachment? People do call them drawbars, cross drawbars, etc... People have been pulling with them for decades. Human ignorance comes into play when they're used for pulling when raised above the rear axle.

Modern tractors with loader don稚 flip over backwards. Pulling from the rear of the tractor is what they were made to do. They pull harder that way and it痴 easier in the machine.

Modern tractors, old tractors, tractors with loaders, tractors without, are all subject to the laws of physics. Both will flip backwards if pulling from a connection point above the rear axle.

Yeah, lets all take a break and watch what happens when pulling from above the rear axle:

Without doing something drastic like hooking on the roll bar a modern tractor with a loader isn’t going to flip backwards. The tires are too small and the front is too heavy.
