Drawbar limits

Steve_Miller · Apr 9, 2004

I was wondering what the drawbar weight restrictions would be on any given tractor as I have never seen this listed for any tractor. I mean the fixed drawbar that slides in and out of the pocket that you can put a trailer ball on. I have broken mine off twice now, I know your probably wondering how but its just from towing my trailer overloaded on the hitch and then driving over rough terrain besides, also I have a drag I use for leveling my driveway that I put on roughly 500 to 800lbs of weigh to dig in and level potholes. I only do this when the driveway is wet as it is much easier to grade.

Just Curious

Just what actually did you break? The drawbar, the "pocket" as you call it, the bolts, or the tractor casing. On my Ford 2120, adn NH TN, they are so massive I'd hate to see the load it took to break them. The attaching bolts I think would be the weakest point.

SEEMS to me the tractor should refuse to pull a load big enough to BREAK a drawbar. not sure i understad just what broke.

I don't have picture posting capabilities so I'll try to explain. The pocket is bolted underneath to the rear end housing and it is also attached to the rod that the holds the three point hitch on. It keeps breaking just between where it bolts on and where the rod goes through. The one piece remains attached to the rear end housing and the drawbar then dangles while still attached to the rod. The last time it broke I took it into our machine shop at work and fixed it while it was still on the tractor. I got it lined up so that when the bolt holes were lined up and there was no tension on the rod holes. Hope you can picture this.

We'd all probably get a better prospective if you told us what kind of tractor it is. Every manufacturer mounts their drawbars differently. /forums/images/graemlins/blush.gif

Its a Kubota B7200DT, its in my profile along with evrything I own or have made.

Thanks Steve

If I were breaking drawbars alot by pulling an overloaded wagon.. I think i would devise a 3pt receiver hitch setup... Either that.. or make sure I have a spare rear end laying around for when it finally tears the bottom of the case out... /forums/images/graemlins/shocked.gif

I couldn't agree with you more. If I ever ripped the drawbar off either the 2120 or the TN, I expect about the last 2 sections of the rear end and case would go with it. I think the load being pulled "over rough terrain" is just way too much. A bigger tractor is in order. Be careful that when the wagon separates, the tongue doesn't take you out from the rear.

Oh. Kubota. Well then, you need to make some changes. Andy and Soundguy are right. Eventually, you will break the rear case. Drawbar capacities are based on what they call the "Iowa Standard". That is what the manufacturers base the breaking strength on. Kubota lists the drawbar capacities in the Owners manual, but you can get a more accurate figure from a dealer or by calling one of the Kubota regional offices like the one in Columbus, Ohio.

By the rod, I presume you mean the sway control links.
