Snow Plow Repair

[Diamondpilot]

I bought this old Meyer Plow last weekend for $100. I stripped it of the snow deflector, cutting edge,and all the other items like the chain, angle cylinders, trip springs, and every nut and bolt. The problem I am having is it has sat out for years and is seized up on the tilt axis. I have sprayed it 2 or 3 times a day since Saturday with penetrating oil and given it a few whacks with a sledge hammer with no luck. I have put pressure on it with a 6 ton jack with no luck as you can see.

My question is how to get it un-stuck? I do not have a torch but a buddy does and that may be my next step. I have also just though about cutting the pins that are in there with a Sawz-All in the gap as seen in picture 4. Also, I removed the cotter pins and from the way it looks to me there is just maybe 5/8" pins in there that can be drive out with a punch and hammer, am I right????

Here are some pics. Any insight will be helpful. By the way its a Meyer model ST-78. Its 6.5' wide and I plan on putting it on my tractors FEL as many others have done.

Thanks in advance.

I'd try a 3# hammer applied (not slammin, but decent taps) about 20 times to the sleeves the pins go into. That might loosen the scale. After that, heat wrench, even propane/mapp torch, plus PB Blaster or =, plus hammer. Don't cut the pins just yet! Jack as positioned might break weld at the brace - maybe a 4x4 between the jack base and the brace would spread out the load?

I have looked and do not see any but will take another look at it.

Thanks for the idea.

No, my plow had the cutting edge bolted on with 8 1/2" carriage bolts. Actually the cutting edge is brand new as of about 10 years ago when the thing got parked. Anyway, it trips at the pivots at the end of the A Frame.

Has a Meyer stick on the back side. Mostly worn off. It is under the bottle jack in picture 1. It says its a Meyer ST-78


Would it make a difference if its a Fisher?

I am sure its a Meyer ST-78 after doing a google search. I found this link where a shop rebuilt one and its identical to mine.
