    Loader boom

    Had a need to build an extension to my tractor loader in order to extend the reach out from the loader and to gain height over the bucket height. Used drill pipe and scrap plate.

    Used primarily to set shop walls and trusses. Extended too height from 12' to 17'.

    Re: Loader boom

    How much harder is this on the front axle/spindles? I’d hate to be lifting something heavy and have that weight be multiplied by the length it sticks out equate to a broken piece of equipment or even worse injury. Looks good.

    You do have to watch the load limits. I am only lifting 100lbs. to 200lbs for walls and trusses. The tractor in the pic is a Farmall M. I now have a Massey 1100. Tractor will lift 1600lbs at the loader. Axles are the weak point using an extended lift point.

    I do that with this tractor, I have two pieces of 3X6X3/16" rectangular tube,, I slide them over the forks.



    The tube came 24 feet long, I cut it in half, so the pieces are each 12 feet.
    I can reach 22 feet high at the tip of the tubes, I set a 30 foot long beam with the machine at 22 feet high.

    In my opinion, the extension does not put extra load on the front axle, at all.
    The loader is capable of lifting 2200 pounds, at the bucket pivot pins.
    If the load is moved twice as far out, the load that it can lift is only half, or 1100 pounds.
    There is still the same 2200 pounds of force at the area of the bucket pins.
    Double the distance again, you can only lift 550 pounds,, etc,,

    You can not lift 2200 pounds twice as far out, the hydraulic control valve stops oil flow at the max pressure,,

    The building behind the tractor is all welded steel,,
    The peak of the corner of the roof that is seen at the highest point is 22 feet off the ground.
    That is where I was setting the steel that high.

    Re: Loader boom

    Here is one of the reasons I have two tubes,, I built this chicken coop in the shed, then moved it with the extensions.

    That coop is 12X16 feet,,IIRC,,
    That was a "while" ago,, behind the coop was our functional "C" Band satellite dish,,

    AND, the frame that the coop sets on was welded using my then owned Miller Bobcat.

    Re: Loader boom

    Ah there’s the pictures of your tractor boom, I have something like that made when I took the grain bins down except the base was 6 inch channel iron about 3’ long and 2.875” pipe is 10’ long with half inch plate of iron welded to it like a flag on the end with a hole big enough to hook a chain hoist on it and a link of half inch chain on backside for support chain or strap to hook on to. I need to unload it but I have 3 of them made.Name:  7E9C0B0C-3B9D-45B9-980B-A5C468FB7AE5.jpg

    Make sure you keep them,, I would bet that they could lift a milling machine (when you get one!! )

    That is my 72" cut, 24HP, Onan powered Gravely 24G,,
    MANY guys on a Gravely forum have stated to me that I have the LAST 24G in captivity that still has a roll bar on it,,

    I guess most people remove the roll bar, because, back in the era of this tractor, a roll bar was unheard of,, yet,,




    AND, that mower deck alone weighs almost 1,000 pounds,
    with the deck under the tractor, it would be almost impossible to turn the tractor over.

    Re: Loader boom

    Those things are behemoths. Those rear fenders look about like the ones that came on the wheelhorse D250. Nice GT btw. With no engine in the front I can see having and using a front end loader on that with ease. Does it have power steering?

    I have an F935 JD that has the roll bar and hard canopy which I have considered puting on a garden tractor. Not sure I want to butcher the f935 just yet. If I ever move out of the city to the country and get a decent size lot the 72” mower on the f935 will come in handy.

    Yea, it has power steering, and hydraulic lift for the mower.
    The "2 clutch" transmission means no shifting, just rock the foot pedal for forward and reverse.

    almost sounds like a hydrostatic transmission. Most of the JD GT tractors from 140 up to the 430 455 and 7xx tractors use some variant of a hydrostatic transmission. The older ones ‘92 through early ‘70’s used a sun strand and are bullet proof. Gravely is a tough tractor.

    Gravely used a total gear drive transmission,, 4 gears, plus high and low, for 8 speeds total.
    Then, the "clutch" operated one of the two clutches, one clutch for forward, the other for reverse.

    Very cool, no shifting, just engage the clutch that was for the direction you wanted to go.

    Reverse was geared slightly slower than forward. The clutch would "lock" into forward, but not into reverse.

    If you look at the pic, the big black pedal rocked forward, or reverse, whichever you selected.
    Some Gravely tractors had a hand lever that extended as high as the hood, the clutch was then hand operated, forward, reverse,,

    The big difference between this, and a hydro was that Gravely did not have variable speed.
    BUT, the hydro is known for sucking up 10% to 25% of the horsepower in friction losses,,

    That is one of the reasons modern hydro tractors have such high horsepower engines,,
    the transmission wastes so much horsepower,, compared to gear drive.

    I have a "larger" hydrostatic drive tractor,, I now mow with, two pedals, forward, and reverse, variable speed,,
    BUT, this tractor has a 41HP diesel, and the transmission wastes a LOT of power,,

    I have an M field tractor, no loader. Mine is narrow front. The wide front, I'd be careful about loader weight. They weren't (I believe) really intended for loader duty. I'm not familiar with the Massey. Likely the lift will be restricted by your pressure relief, but be quite careful with uneven terrain & sudden maneuvers with all that leverage.

    Spindles can snap or axles crack when traveling with a heavy load. I always go very slow even without using the loader boom. Seen way too many tractors with broken axles. Going to fast on uneven ground and bouncing a load can easily double the load on a axle. My Massey has a much more stout axle than my old M. The Massey has power steering and live PTO, which is why I upgraded.

    I broke a 4020 spindle ( a lot heftier than what you are working with) pushing out rocks with a blade. The good news is that it made a great rounded pounding post on my upright anvil.

    Re: Loader boom

    Imagine trying to do all this without power steering on a backhoe with a loader, it’s what I have been fighting each rock and dirt load. Makes it hard to accurately line up on anything, especially with a boom on it. Hopefully after my pole barn is done I can get power steering on mine, I got a spare just need time and place to do it.

    I've had an old 1961 International B275. IH had a long series of great utility tractors beginning about then with the B275. It isn't a bulldozer by any means. In the 1990s A neighbor wanted to borrow it. I had misgivings, but let him take it.

    Soon I could hear crashing, I went to investigate. His lawn was full of boulders sticking up a few inches. What showed three inches was typically three feet. He was getting a good running start & crashing the loader into them. I went home with the tractor. The subject of borrowing it didn't come up again.

    I've got about 55 years experience digging out big rocks without the proper equipment. First two thirds of my life, the most expensive thing I ever broke was a hand shovel. I'm more productive now, but fails are more expensive.
