Amount of weight on 3 pt lift arms?

randallinMo · Aug 1, 2008

I recently built a 10 ft. dump trailer out of an old Ford F350 ton truck. Due to the frame configuration the tongue of the trailer is lower than I would like. The trailer slopes to the front. When I raise the hoist the bed does not have enough slope to it in my opinion to effectively unload properly. The hoist was mounted as far to the rear of the trailer as the frame would allow. If I use a 3 pt hitch drawbar on my 4020 to raise the tongue of the trailer, this allows the bed angle to increase enough so as to unload properly. I am concerned that when the trailer is loaded, it will make the front end of the tractor too light. How much weight can you safely put on a 3 pt hitch drawbar?

on a 4020, are you kidding????

we have a 3pt drawbar on a 55horse oliver tractor model 1365. we use it to haul round bales and there are roughly 8 out of 11 bales that are supported by the 3pt drawbar. these 8 bales are in front of the trailers axle so it is in fact tongue weight. thats 900-1000 lbs a piece for the rolls. another option is make a 2-wheel dolly to support the weight of the front, much like the old style dirt pans with the dolly on it

You're not going to hurt that 4020 any...nothing to worry about.

Supergrumpy, I guess I don't know what you're trying to say. ?

That 3pt. drawbar is going to be the weak spot. I bent one into a U with our 4020.

Any idea how much weight was on it when it bent?

Listen to Mike and other folks who have a clue what they're talking about.........is it a cat. one or cat. two drawbar? Either one can and will bend on a 4020 with enough weight on it. Given that you're only talking about a 10 ft. bed, you're probably alright....with a GOOD drawbar and also with the weight of the front end. I'd be more concerned with what happens when the load in the trailer slides to the back and the front of the trailer comes up; the roller on the cam follower (not sure of the terminology, but anyone who's had much experience with 3020/4020 knows what I'm talking about)is probably coming off (inside the rockshaft control vavle housing). Not a big deal, but you may (or may not) have to remove the housing to put it back on.........until you do it again.

Not sure of weight. My front end loader couldn't lift it and it will lift about 4000 lbs. so I was trying to drag it. With the weight of the loader and the tires full of fluid it will pull alot ! It was all I could do to move this oil tank cut in half on skids in the mud. After I got it moved and all of the gook emptied out of it I could lift the end of it up to back a trailer under it. I think I was finally able to push it sideways and roll it over and finish dumping it out.

Thurlow has a good point about that hitch being able to freely pop up if the weight transfers. I would look into making the hitch lower on the trailer to match up to the factory drawbar in the high position. This will be way safer.

if I was to ever buy a green tractor, it would be a 4020, terrific machines

your trailer should work just fine

There is only one way to do this right and that is with the floor of the trailor level make an adjustable hitch on the trailor frame so that it can be hooked to the swinging drawbar only!! Also I hope you are planing on using a heavy duty jack on that trailor for when you want to unhook. Also take a look at how farmers put extra bracing from the drawbar to the quick-hitch on the 3-pt and run with 3pt. all the way up when pulling a grain cart. There will be a lot of rocking motion on the front of that trailor and that has been known to snap unsuported drawbars on tractors a lot bigger than a 4020. Armand

I have hauled 1600 lb round bales on my Kubota L-285 30 HP with no trouble.
