Pulling with the Drawbar

[bcp]

Simple to put on a 3pt implement, like a box blade, lift it high, and pull from the draw bar with more safety.

I think you have hit on a significant cause of many rear rollover...people are expecting the load to come with them instead of remaining stationary therefore they are taken by surprise when the rollover starts and precious reaction time is eaten up. Unless you know for a fact that the tractor will spin out or the load will come with you, expect it to roll over backwards.

That may very well be the case, but if your pulling in tough conditions, I don't know of anyone who would be pulling in a higher gear. Generally, there is some knowledge about the task at hand and some thought about the size of the equipment vs the size of the task. Also, if you have more than hobby experience on a machine your reaction to what the machine is doing can be very quick. That picture earlier in the thread was pretty misleading about taking 5 seconds to react. If your front end starts coming up its quite motivating to hit the clutch!

Drawbar pin hole is behind the axle centerline. As the front end rises, the drawbar pin hole drops so the lever arm creating the moment around the tire/ground contact point is reduced so there is a reduced moment trying to flip the tractor, and it's the front rises the moment is further reduced. Elementary statics. Anybody familiar with tractor pulls in the old days when things moved slow, there was a person at the front end of the tractor checking the front wheel height. If it exceeded a certain level the pull was stopped because of the danger of flipping over. Given enough traction, it will be possible to flip a tractor over backward anytime the line of pull is above the tire/ground contact point.

Sometimes gearing up will result in more actual "pull" and less wheel slippage.

That's the problem, most people here on TBN are just that, hobbyists, and as such often have less than adequate knowledge for the task at hand. That isn't a criticism of anyone, it is to be expected of anyone who hasn't had a mentor to learn from. Sometimes a learning curve is very steep.

Exactly! A person should always anticipate that things might not go as planned and be prepared for when they don't.

If you use a cross draw bar, and say your skidding a big log. Can you run the chain over the cross drawbar and then hook to the pulling drawbar. Then raise the hitch enough for the log butt to clear the ground. Is this effective or a waste of time.

I'd say you probably shouldn't, sure would like other opinions on this.

I'd say this would have he same effect as connecting the chain directly to the cross draw bar.

We had a guy here in Marlette roll a Farmall H over on himself. He hadn't been here long - moved from China with his sister and her husband. Anyway, he was trying to pull a heavy (too heavy) gravity box with a chain (?) and for whatever reason he took the chain off the draw bar and hooked it around the seat bracket. Well it rolled right over onto him in almost an instant. He was messed up pretty bad (head injuries) for awhile but is OK now. Best advice I've seen here other than hooking up low is to GO SLOW.

Like that cage on your tractor Glade. Some close ups would be real interesting. A great way to mitigate a roll over along with a tree slap now and again.

Have never had a problem pulling logs with a cut size tractor with the 3 pt. Would never consider pulling the same logs with the 3 pt on a tractor that had a tire as tall as or approaching the size of a man. That is the kind of fulcrum leverage that gets people in trouble. Witnessed a guy who got killed pulling too large a hitch with an Allis WD 45. Popped the clutch and was over in a literal instant.

If you're suggesting that the geometry of having the draw bar connection below the rear axle - all by itself - precludes a rear rollover, you are wrong. There are other geometric possibilities that come into play, but what you state isn't automatically true.

xtn is right.

Any connection above the contact point of the rear wheels with the ground can be dangerous.

This fools a lot of people. The wheels run around the rear axle, and if one does not look very, very carefully at a video of a backwards rollover it is easy to be convinced that the tractor rotates around the rear axle, when in fact it rotates around the bottom of the rear wheels.

If a guy had a cable say 95' long and wanted to pull over a 12" oak tree that is about 65 feet tall. How far up the tree would be a safe pull. At what angle would be safe hooked to the drawbar without picking up the rear wheels.

Is it dead or alive?

From my experience pushing them over with the V417, they will break if you get up too high.

The dead ones will break, pushing lower than one that is alive. Another unseen factor is that the tree dead or alive, may be hollow.

This one was not hollow.

 

[Walkin Horse]

It is alive and in good shape. I know what your talking about. Last week at the hunt club they were cutting some dead standing trees. They wanted me to push it with the bucket. No way. Way too much stuff to fall on my new tractor.

No matter where you hook it, if it's above the height of the drawbar, you will be pulling up on the back of the tractor.

I'd hook it as high into the tree as I could get it for the best leverage, and pull on it SLOOOOOWLY to see if it will come over...

You could run the rope from drawbar to a pulley block mounted low on a tree (at drawbar level or lower) then run up to the pulling point on the tree of interest. I usually have to do that just so that the pulling direction of the tractor is away from the fall direction of the tree. But it also serves to keep the pulling force on the tractor down low.

If there is any danger of the tree falling in some other direction and pulling your tractor along for a ride, make sure you have lots of extra rope between the tractor and any pulleys or trees!!!!!!

 

[Walkin Horse]

I'm kinda thinking no more than a 30* angle and that's probably close to 40'. If my sighting is right looking up a 45* sq the tree is 65' to 70' tall.

 

[Xfaxman]

What is the drawbar pull rating on the tractor that you will use?

 

[All In A Days Work]

I like s219 idea if you have another tree to pull from.

Anyway here is a video of how not to do it with an F250.

I don't know but I will look. What should it be. I don't have any idea.
