3510 drawbar capacity

[grunewald]

Anybody know what the tongue weight capacity on the drawbar of my 3510 would be? Sure dont want to crack my rear casing.

I've never seen it published anywhere either by Mahindra or TYM, but I sure wouldn't push it. It's designed to pull its load horizontally rather than made to support a lot of vertical load. Its long/adjustable length is also problematic in regard to tongue weight. Tongue weight numbers I've seen for other similar machines are not reassuring. As a practical matter, I'd probably want to keep it at or below 500 pounds +/-. Yes, that's probably way too conservative but better safe than sorry.

I use a 3-point mounted trailer hitch receiver for towing my trailer just so I don't have to worry about tongue weight.

The drawbar that came with my tractor is close to an inch thick, and the rear casing is steel ( I'm pretty sure) so I would think it could take a lot of weight.

It should be stated in your owner manual but this may help. According to my Ford manual, it's about 48% of tractor weight on the short hole and about 35% on the long hole. But you need to know what your tractor weighs to use that guideline. The actual weight will depend on your tractor's mounting bracket. I've posted mine simply as a guide.

My Ford weighs about 4800lbs.
Short (9.25")- 2300lbs.
Long (14") - 1745lbs.
The measurement is from the end of the PTO shaft to the draw bar hitch point.

In round numbers, the 3510 is about 3,500 pounds. 35% of 3,500 pounds would be about 1,200 pounds tongue weight in the rearward position?

I wouldn't do it, but I'm more than happy to sit back and let someone else do that test and report the result.

Drawbar/ tongue weight on a [2800 pound]Kub L2850 is listed as 1400#. The [larger+heavier] Mahindra should do a bit more.

That is amazing. The only tractor manufacturer that I know of that currently publishes max drawbar tongue weight in its specifications is Deere. Most of the current Deere CUTs and UTs are either 400 kg (882 pounds) generally below 45 HP or 500 kg (1,102 pounds) generally above 45 HP.

IMHO, the drawbar on the L2850 is not very impressive compared to my 3510, but I can't say that I have examined how the L2850's drawbar attaches to the tractor vs the 3510. I wouldn't load my own drawbar with 1,400 pounds of vertical load, but maybe that is just me.

It seems high to me too. I think that amt of dead weight there would be abusive in bump loading conditions. A trailer tongue tho is flexible and the flex would limit peak load. The Kub picture shows a trailer attached via tongue. They dont make any distinction from this to dead weight situated inflexibly on the drawbar.

In my 3215 owner's manual it states the maximum vertical load on the drawbar as being 969 lbs. I would suspect the 3510 to be about 1300 lbs if you keep the same weight to load ratios. If that helps.

Now you know two. I just gave you what the Ford manual stated to use as a guide. When you look for the specification, look for "Maximum Static Downward Load" under/in drawbar section. But you are probably wise to derate the Ford spec for your tractor.

For the sake of comparison, the John Deere 3520 weighing 1316 kg (2 900 lbs) without cab has a Maximum Static Vertical Load of only 255 kg (562 lbs) on the drawbar.

Sorry. Don't have 3510 info.
My Mahindra 5525 manual has very little info on the drawbar. No load info. Just a warning about excessive loading when towing a loaded single axle trailer and a reminder to lock the swinging drawbar in the center position when towing on the road or in the fields.

The drawbar on the 5525 is mounted on a bracket which in turn attaches to the tractor structure.

The downward component of the tongue load is carried by the rear part of the support bracket below the drawbar. The upward component of tongue load is resisted by the front part of the bracket above the drawbar. The tongue load is transferred to the tractor structure via the two pins that attach the front part of the bracket to the tractor structure. There are two bolts that attach the rear of the bracket to the tractor structure.

The pulling load on the drawbar is transferred to the tractor via those two pins and the pin that attaches the front end of the drawbar to the bracket.

I would be happier if Mahindra would include tongue load limit and drawbar pull info in the ops manual. Wonder if they have that data (how about it Mahindra dealers?)

I checked the Nebraska tractor test website and found nothing on Mahindra. Apparently Kubota and Zetor tractors have been tested there but not Mahindra. Bummer.

Didn't mean to slight you or ignore the data you posted from your tractor's manual. Perhaps I should have said "currently publishes max drawbar tongue weight in its advertised specifications..."

I do agree that drawing any conclusions about the Mahindra 3510 from specs for your Ford 3910 could be quite risky as the drawbars are of different length and use very different tractor support schemes.

Your drawbar attachment scheme looks much safer than the one on my 3510.

How about it Mahindra dealers - Any of you have this data?

Sounds like alot of people asking the same question, cause no specs. from Mahindra. My 3510 has the drawbar bolted on the bottom of the differential, a solid plate covering the whole bottom of differential, so has a lot of strength. But not about to push my luck without any data. Have a 20 ft. trailer, empty weight of 3000#. A lot of weight on the drawbar. Will be safe and get a 3 pt. receiver hitch. Would like to pick up a used , cheap, wagon someday, use for light towing around the farm.

I could only find a limit on towed weight of 1.5 times the tractor's weight in my Kukje (Branson/Century/Zetor) manual for 28 through 47 HP series.
I "ASSUME" this is about stability and therefore refers to the total weight of the tractor WITH loader and loaded tires ...if so equipped.

It would be 1.5 x something between ~3850 (naked tractor) and ~6400 (loader, bucket & Rimguard R4s) lbs.
What percentage of that would/should/could be "on" the drawbar isn't spec'd, though I suspect that it could be more than the 10 to 15% guideline for towing trailers on highways (smirk).
