D-ring for the chassis front

[The Evil Twin]

The typical weight distribution for MFWD tractors is 65:35 towards the rear. The wheelbase of these tractors is about 65", and they weigh about 2200 lbs. The D_ring looks like it's 8" or so above the front axle centerline, and the tires are 24" OD. If we imagine the front tires to be (magically) superglued to the ground and the drive shafts frozen, we can compute the amount of pull needed to lift the rear wheels of the tractor by summing the torques (moments) about the tire contact point:

2200 * (.65 * 65") = (24/2 + 8 ) x PULL on chain

2200 * .65 * 65/20 = 4648 lbs.

Since the pull needed on the line is more than 2x the weight of the tractor, the tires will slip long before the tractor lifts the rear wheels, and the D-ring is completely safe. If you're paranoid, carry some heavy implement on the 3pt; it will definitely help the pull, since the rear wheels will do most of the work, anyway.

And 4600 lbs is going to be far less than the resistance of a car sliding across a slick surface.

in regards to using it as a tie down
Anything 10k or more has to have 4 points of contact. IE , a chain & binder on each corner but if under 10k two is fine. 4 is better but 2 is acceptable. Disclaimer don't take this as legal advice please review laws that apply for you
look up CFR title 49 Chapter 3 Part 393.128 (b)

Get a "Recovery Stap" from HF instead of chain for pulling cars and other items out of jams. About $27 for a 9000 lb. strap. They have stretch to absorb the shock. Much less stress on car parts and the tractor. Make sure the D-ring is sized to accept the hook (ask me how I know, Duh). I've used mine a couple of times with great success. I don't use it for anything else though - every "tool" has its purpose - the right tool for the right job is part of being safe.

Be really,REALLY careful about pulling 'cars out of ditches' with a chain to the front of your tractor !!!
When (not if..) the chain breaks you might not even get to say 'Oh Sh.. '

I was thinking the same thing. I had that happen once (with the tow hook on the front of my truck). Now I'm a big fan of kinetic recovery ropes.

Edit: I see Bee-Positive beat me to it. <lol>

Even with straps, a damper should be used.

When your truck or ATV becomes stuck and the recovery requires a tow or winch, remember to always use a strap/cable damper.

By damper, I assume you mean throwing an old moving blanket over the chain?

Yeah. Almost anything, really. Jacket, floor mats, or even a couple shackles. Of course there are the weighted pads made specifically for the task.

I was looking at pulling a car out of the ditch on my road last week, and realized there's no good place on my LX to hook a chain. I could use the draw bar in the rear, but with the 3pt snow blower attached that's not very accessible. So I thought a D-ring on the nose was in order.

I bought the D-ring and loop at the farm store. Didn't have a scrap of steel plate big enough to cover all 4 holes in the chassis, so I welded up some scraps of 2-1/2 x 1/4" bar stock, then welded the D-ring loop to that.

A quick shot of clearcoat to limit rust and voila. Attached with 4x 3/8" grade 8 bolts (I could have gone bigger but neglected to measure the chassis holes before I was at the store buying hardware).

For some reason I'm not a fan of dangling loops that rattle...I'd rather have a fixed hook or ring.

"The wheelbase of these tractors is about 65", and they (MFWD tractors?) weigh about 2200 lbs."
Really?
MFWD tractors typically "weigh about 2200lbs"?

 

[Downeaster]

I was really considering the D hook, but I have no welding equip. i thought about drilling
through the plate, so I checked the thickness, and it is way to thick and not worth the
effort. So I will just buy a couple of tie down instead.

Used to run chain through an old tire to absorb some of the energy

An old blanket will do the same thing. Drape it over the chain about mid point.
