Bucket/implement ups or down?

F=Ma
Force=Mass x acceleration
If somehow the implement was above the saw horses and gained a good ammount of momemtum, c-r-u-n-c-h.

Something's not right here.... if the 3ph is properly set up, an implement should take at least 2 seconds to lower, and the load on whatever it hits shouldn't be significantly greater than the weight of the implement. Does your mower drop like a rock? Otherwise I think your sawhorses were not nearly up to their rated capacity.

I would have thought your method was totally safe. I guess your next bet would be to use jackstands to hold it up - I wanna hear about the mower that shatters some cast iron jackstands!

Actually, it depends what you are using the 3pt for. Different tasks and times.

I use jack stands under heavy equipment. 4 - each rated at 3 or 5 tons. But a side shifting load can induce a bend and cause them to fold over or dig into the ground and still fall. That's why I use 2' long 6x12" blocks too. I don't want to be crushed or just smooshed enough so I can't inhale and have 2 minutes to berate myself for not taking the time to block it up right....

In retrospect, I think there are few factors that caused the saw-horse
failure in my case. The first is that the contact point between the mower
and the saw horses was small, maybe a square inch. I suspect
it would have been easier on them if the load was distributed over
a wider area. Second, if the mower came into contact with one
of the horses first, it might have failed b/c the mower is a lot heavier
than its rated capacity (maybe the first one failed, then the second
one failed as the mower continued down). And thirdly, the mower
did not fall "like a rock", it went down in a smooth controlled motion,
but there was still an impulse of energy suddenly transmited to the
saw horses as this heavy implement in motion hit them.

Like everyone has said, both safety and minimizing strain on hydraulics (release pressure = no pressure on seals = longer seal life).

I'm always amused when I see stuff on dealer lots with FEL buckets way up in the air. One leak (just as likely on brand new as on used) and bucket will come crashing down on whatever happens to be below it.

At least it causes you to look. That's the same reason some car lots raise the hood on all of their cars.

Most of those tractors with the fel raised way up have a safety sleeve around one or both cylinder rods to keep the fel from crashing down. If they don't, they should.

The ones I've seen don't, but I agree that they should. For me it is something of a sign of which dealers are cheesy outfits that I want to avoid. The dealers that I've found best don't do this.

Actually.. she feels as solid as any 2-poster loader I've ever used. The bucket is mounted offset to one side a, dthe arm attachment point is offset tto the toher side. the connection under the tractor goes has 3 points and is angled to spread the load out pretty evenly.

I DID add rear concrete ballast weights to counter ballance her.. otherwise she's darn near impossible to steer with a 1000# bale on the front end.... and even then.. only when rolling..

Chris,

My neighbor has one of them loaders that sits off to the side of the tractor. Except his tractor is an actual offset tractor so a bit different. Does that thing get a little tipsy with large loads in the bucket?

Hmm.. I don't know where this 2-second rule came from but I know my 3pt hitches on my fords from my 46 2n all the way up thru my NH 7610s will drop like a rock under load if I dump the 3pt hitch lever.. Probably a half second I'd guess. As for the stands only supporting the 3pt load.. well? A 3pt load can be pretty hefty.. Even my 40's & 50's oldies can lift 800+ # on their 3pt.. and the 60's oldies can lift up to 1200#.. and the bigger guys can lift over a ton.. So.. you have to have a support that will hold the weight of the load.. plus and shock loading if you plan on dropping the load.

That's why I use 2' long 6x12" blocks too.

Evenin John,
Big wooden blocks are in my inventory and get used on a regular basis !

I like the look of your shop -- has that "lived in look". Good look'n restoration underway too.


You can tell a lot about a man's shop by the size of his wood (blocks that is, you guys need to get it out of the gutter....). Big projects just seem to need big hunks of wood. There was a radio talk show, Garage Logic, that was just talking about "garage wood". The precious blocks of wood that have been used for years in about every project and have the marks to show it. I know my hunks of wood are used as much as any other tool.

I hear ya. When i got my loader on my 55' ford 850.. the bucket wouldn't even make a good spagetti strainer it was so 'holy'. i had to cut a hug section out and reskin.

pic 1 is the cut, pic 2 is the new floor welded in, pic 3 is it in primer, and pic 4 in paint.

Hello Soundguy, I have never seen a FEL like you have in your pictures, could you post a side view of it. I have a Farmall A I might like to put a loader on like that one. Also on my MF35 FEL the cylinders ore relieved when the bucket is lifted high as it will go, I really don't like to leave it up in the air like that either, So I am thinking of building a hanger for it.

The manuals for my Deere LX6 and 5105 both indicate that it must take at least two seconds to drop, for safety. I think that is sensible. They have adjustment valves for rate of drop. I think most brands of tractors today do, though stuff made in the 50's and 60's may not.

 

[Soundguy]

I think you are reading the manual backwards. It sounds like they are say.. that for safety.. you want the bucket to take 2 seconds to drop.. not that it cannot drop any faster than that.

Most spool valves can be feathered to allow slow dropping.. including spool valves from the 50's. if i just barely crack the fel spool.. it slowly lowers.

However.. none of that comes into play if a hose pops or fitting breaks.

That IS how I'm reading it... you adjust the rate of drop control so that it takes at least 2 seconds to drop (rear implement on 3ph, not the FEL bucket - I don't think there is a specified setting for FEL). I notice a major difference in rate of drop between my LX6 (760 lbs?) and my scarifier bar (200lbs or so). My current setting is right around 2 seconds for the LX6, but if I get a heavy box blade or something I'll have to start monkeying with the adjustment knob.
