Bent cracked loader arms

[SweBota]

I'm with the Finn. Commercial snow clearing here in Scandinavia is done at much higher speeds than when you just clear some driveways, and the side forces can be huge when you hit a curb or a frozen ice berm. All smaller machines use subframes or steel beams from the hitch all the way under the tractor. It also puts the force low where it should be. On bigger tractors it's still rare (except wheel loaders) but it does exist. The biggest manufacturer of FELs, Aaloe-Trima says you absolutely must use the special side supports in that case.

Here are some pictures of these supports, both commercial and home made:

Cool thanks i can see how this would help

It does look like it would provide lateral support, but it seems that it would only accomplish that if the FEL was all the way down. If one operates by riding the stick and constantly changing elevations, as soon as you leave the "pocket" the support is gone. Here are some more photos:

As an aside, I really like the the apparent strength of their straight snow plow attachment system.

That is a strong setup. I see that the plow is free to float about five inches in those slotted push pin holes and can trip the whole blade against that center top shock absorber and that angle of attack comes from the dump on the loader hitch. I wonder if there is any relief in the angle piston?

Whenever I read about this I am reminded of a VERY hard lesson I learned.

I was brush hogging with my L39. I had the GST trans in 6 or 7. PTO Rpm. I was moving along pretty well in 4wd. I had the bucket still on the front because i would use it to knock down the tall grass to get a view.

Well...I cut it a bit close working around a tree. Caught the corner of the bucket on the tree at full clip. Swung the 7k lb machine right around and just about threw me through over the steering wheel.

I thought for SURE i destroyed the loader. I ran it through its full motions and it didn't seem to bind at all. I went back up to the shop and took about 3 dozen measurements to prove to myself it was at least as square as the day Kubota welded it up. Amazingly it was perfectly fine.

Lesson learned. The TLBs are tough SOBs.

What would the advantages of that be compared to floating the plow? Unless I'm going very slow or doing something special, like carefully pushing snow out over a grass surface, my experience is that it's impossible to adjust in time anyway.

Also note how close to the machine these plows are mounted with the use of "side-mounted" angling pistons.

I rarely operate faster than 3mph, and the areas I work are unchanging; I know the roads sufficiently well enough to anticipate every (and there are many) obstruction. Like I said, these roads are like goat paths in terms of their smoothness. Floating would have the blade tripping every 5 feet.

That is a very nice looking piece of equipment.

Yup that is a nice looking set up for a plow. As to the road that changes to much for a floating plow to follow I would think you might want to run a grader over it during the summer.
