hi lift jack tips and tricks?

[Looking4new]

I just bought a farm jack (Motormaster 3-ton) and lifted one axel of my tractor and I can't get it to lower. Does anyone have tips on lowering a stuck farm jack? I can get the handle to move the full range of motion, it just seems like the pin is not entering the lower hole like it is supposed to.

Raise the handle ALL the way up to where it will come in contact with the main I-beam. Keeping ALL your body parts that you want to keep away from the jack and the vehicle, grab the handle loosely and fling it down. The jack should do the rest. It will bang, bang all the way to the bottom, if the pins are not seized.

^^^^^
That’s one way of doing it. I prefer to let it down one notch at a time so that I have some control.
Another caution though; make sure that the handle is firmly attached to the jack. I didn’t once, and it lobbed the handle in a steep arc completely over the pickup, landing on the ground 50 feet away.

Ah! A blast from the past! Good thread in 2005.

Lube the reversing lever. Then what I do (which may not be correct) is when I want to let it down lift the handle so it touches the upright then pull the reversing lever down. Sometimes it requires a slight wack with a tire iron. Then crank it down slowly.

Thanks for all of the tips! I first sprayed some oil on the pin that was failing to engage and let it sit for a while. This didn't have an effect. Then I sprayed a bunch of oil on the whole ratcheting mechanism and let it sit and it worked!
I recognize the limitations in using a farm jack over a floor jack, but I think it's the only option for me. My axle is about 30'' off the ground, so I need a jack that gets up pretty high. Is there a better option out there (without spending thousands of dollars)?

This won't be helpful but I'm going with "use a bigger tractor to lift that one up" :laughing:
You could also use blocks between a lower-reach jack and what you're jacking, but that carries its own risks of the blocks popping out...

Now there's an idea... it shouldn't be hard to convince my wife that we need another big tractor.
I thought about using blocks, but the rear end of my tractor is about 5,000 lbs and I'm worried about doing something like that for the reason you specified.

No doubt you are referring to blocks of wood, not cinder blocks which will disintegrate without warning. I’ve even been know to cut a tree down to make them, if I’m stuck on some woods road.

Definitely wood.
I've been known to use a 12 foot 4x4 as a jack block when replacing a pillar under a deck...

TIP:... Use care, stay focused... We had a timber framework for a gold rush era stamp mill lifted to replace a beam and I was getting a little sloppy in my attention to jack, it got away from me and handle came up and kissed me lightly on side of head, did not get hurt, but reminded me it will hurt you every chance it gets....

Only thing I don't like about them is you need a box of "magic parts" to get jack connected to some tractors, implements or vehicles and the standard lip of jack just does not seem to get really secure grip on what ever surface you are lifting at... Does not like the off road bumpers on my Jeep at all....

I’ve got to reiterate to hang on to that handle whenever it is being moved.
Go ALL the way UP with the handle until you hear a Click the down to you hear the Click. That’s the pins locking in place.

If it does get stuck, I’ve had to raise it high enough to get the load off the ground and then let it fall over sideways. The pre shot of oil helps prevent that.

It can...
Fall over
Miss a click if only handle raised or lowered only partly and not work.
With no load and the handle raised all the way up, drop the jack part toward your feet. If the handle doesn’t have its pin fastening it to the jackyou are left holding the handle while the mechanism races toward your feet.
Fall over
Turning the handle loose during the down stroke while lowering can put the jack into automatic pilot and it will click it self down swinging the handle in an attempt to beat you in the jaw.
Fall over

For those that a good cleaning and oiling doesn’t fix, there are repair kits for the pins and springs that make it good as new. Mine was used when I got it 25 years ago and i used it this week.

I kept an old piece of inner tube slid over the mechanism on mine during my jeeping days to keep crud out of the oily pins and gumming it up.

By the way. It will fall over.
