Mounting a snow plow on a LMTV 1078 First Post

[TNriverjet]

I found this today in Evansville, IN. This was all the closer I could get.



It looks like the ANG units have figured out a way to mount a commercial plow!

We have commercial plow mounts for FMTV - they make AWESOME plow trucks! Click here for information/pricing.

We also have studded tires and chains...

Let me know how we can be of service!

I just watched Diesel Bros. episode on FMTV plow truck...WARNING!: Do NOT build a mount like they did!! It is not structurally sound!!

Their design [presumably] assumes that the two brackets that drop down vertically inside the frame rails that hold the plates under the bumper (photo attached - see #4 and #13 on exploded view) provide structure...they do not. Each is only attached with an upper and lower bolt.

Further, the upper mounts at the shackle points mearly "suspend" the plow mount in place but provide absolutely no structural integrity as all of the force from the plow transfers to the very bottom of the mount and acts to push the bottom back, pivoting on the upper mounts.

By way of pivoting on the upper mounts (at the shackle mounting points), their design transfers almost 100% of the force of the plow/resistance to a single bolt on each side that holds these vertical brackets to the frame rail.

A plow mount for the FMTV MUST transfer this rotational force all the way back to the frame rail.

Is that drawing correct...that there is no crossmember on the front except the bumper?

Yeah, I wondered about that when I saw that show. I always saw that angled plate under the bumper as a “skid” plate more than something structural. Basically to keep brush, etc from getting hung up in the radiator & fan. Granted it is a very heavy gauge skid plate... but needed on a vehicle of this size.

There is a forward crossmember - it is shown in a different view (attached), but is does not provide any structure to the DB plow mount.

Oh yea, now I see it in the photo also. I don't have skin in the LMTV game. But I design by the fact that 3 points determine a plane. Mounts better be darn solid for a plow.

Thanks for the edited in details compared to first post. Offers much more to the knowledge bank in here. Kudo's

Might check the show Diesel Brothers as they put a plow one for an owner.

OMG...thank you TNriverjet...

Admittedly it was a good episode.


I took this snapshot of my hotel TV screen the night it aired.

That plate on the newer trucks is fiberglass. It weighs about 1/3 the weight of the steel piece, and costs 10 times as much.

Looks like it is from a diesel brothers episode (some of you will get the inside joke)

Nice looking plow setup. Where did you get it installed? I'm looking to get a plow mounted on or 1078A1 for our county in Central NY. We are looking for a experienced vendor that has mounted them on these trucks.

Wilco fabrication in Littleton, NH built the mount, and the Boss dealer wired it. The mount is awesome, I would wire it myself next time...
