Pulling a trailer with your tractor

[Max Power]

a load connected to the three point hitch always has the possibility of "walking over" the top if the load is suddenly increased.

when the load is connected to the drawbar and the load increases it does NOT create the "walking over" since an increase in load pulls the front wheels down .. the opposite of the 3 pt hitch.

Yep, what you are doing is exactly what I was looking into. Wich I had a that nice dump trailer you have there.

You could go this route if you don't have a dump trailer, make your own dumper. This is how I did it before I got the EZ Dumper
see pic.

Only problem is for me the draw bar is to low to use with the over the road trailers I have.

It is simple physics that the higher the hitch results in more weight on the rear tires, thus increasing traction. Hooking to a drawbar in a near horizontal pull adds next to no weight. Raising the hitch not only tries to lift the object being pulled (less friction with the ground) but it ads that weight to the rear tires.

That is not a simple truth. There are lots of variables to consider. I won't discuss them all, but will just give an example to prove I'm right.

Imagine a single axle trailer with the load balanced over the axle while the tongue is level. The tongue weight lessens as you raise the tongue because the load starts tipping back.

Just one example. Making a statement saying that physics always demands a certain thing is folly unless you carefully think through all the possibilities and define a limited scope.

Possibly??

I was really refering to pulling something like with a chain or cable or something that has a high resistance to move, unlike a trailer with a fixed tongue.

But even the trailer example can go either way. It will all depend on the trailers resistance to move. In a static situation, sure it will take a tiny bit of weight off the hitch. But factor in trying to pull the load, perhaps with a little resistance like soft ground, and the higher hitch is going to increase the weight on the tongue more so than a lower hitch.

I guess I will choose my words more carefully so they cannot be taken out of context.:thumbsup:

It's amazing how much stuff I learn here! I use a 3 pt hitch lift all the time, never thought about it lifting with gravity! From now on I will use a safety chain around tow bar to limit it ability to raise at the wrong time. Thanks all!

I use a 3pt receiver to move empty trailers all the time. The most weight I've moved was my dump trailer loaded with eight yards of mulch.

Just remember not to try to raise it with it chained:confused2:

Set the chain to stop the 3pt rise just beyond the lift limit if you are worried about feeling the resistance the chain will cause, it could bend the draw bar for sure but you can feel it before that happens.

I would probabally word it....

The drawbar is designed to "lessen" traction enough that there is an unlikely chance of rear tip-over.

Sorry LD - you're missing my point...!

With a 2wd tractor, I will not argue with your logic that a higher towing point will increase traction - although from everything I have read, been taught at ag college, and seen in practice this is not advisable...

However with a 4wd tractor it will not improve overall traction. It may increase rear wheel traction, but will also reduce the additional traction available by the front wheels.

I had assumed (maybe incorrectly) that the thread was refering to a 4wd tractor... That is why I say the draw bar offers the optimum traction...

I do enjoy a good debate :laughing:

I think you are missing the point.

Because the same principal applies on what we are "refering" to as 4wd.

Because they have MUCH larger rear tires than fronts. SO unless we are taling about a machine with the SAME sized tires front and rear (large articulating ag, JCB backhoe, Skid Steer, to name a few) the same principals apply as a 2wd.

Because if you have a tractor like mine, with little 7x16 fronts and 11.2x24 rears, taking 100lbs off the front and adding it to the rears is going to SIGNIFICANTALY increase traction.

While the traction increase may not be quite as much as a 2wd, I'll give you that. There is still a traction increase though.
