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.
