I broke the power lift mechanism on X540 today.

OK, It is the hydraulic lift connecting rod that is the weak link of the power lift mechanism. It has proven no match for the today's heavy snow.

For clearing today's snow, I had to resort to a kind of multi pass, zig zag approach. Basically, I had to lift the blower, go forward a few feet, and then back up and drop the blower, and push forward again. So the power lift gets used a lot!

Half an hour into the task, as I pulled up the lift tab, I heard a very loud bang, and after that, the snow blower will not pull up again. I finished the rest of the work by keeping the blower in the drop down position, and following a zigzag pattern. That has been proven slow, and tedious 3 and half hours.

Afterwards, I brought the X540 back into the garage, and checked everything out. Guess this is what happened, the weight of the snow has proven to be too much for the lift mechanism, and it bent the fork on the power lift connecting rod. There are two connecting rod, one of them is normal visible, the other one is under the tractor. It is the second one that failed. See the picture.

Will give the Dealer a call tomorrow, see if they can help out soon. We have more snow coming!

Re: I broke the power lift mechanism on X540 today.

Looks like the cotter pin fell out of the small hole in the pin. Then the pin was able to work it's way out of the clevis. I would straighten the clevis and put it back together with a new cotter pin.

Re: I broke the power lift mechanism on X540 today.

This has happened to me before. The ring loop that is supposed to keep the pin in place (through the clevis) came off. Once that happens, the pin will work itself out and once it gets past one side of the clevis, you get the result you have there. Replace the ring loops with actual cotter pins, then bend them over so that they CAN'T fall out. Just be sure to use as thick a cotter pin as will fit. Also, you can use a vice to straighten out the clevis. I repaired one like this 3 years ago and it's still going strong.

BTW, do yourself a favor and do this to both ends of that lift rod as a preventative measure.

Correct. No need for dealer intervention.

Looks like the pin is still there. Put in a new cotter pin and you are good to go.

Re: I broke the power lift mechanism on X540 today.

Good information. I guess there is no real need for dealer to work on this. My gripe is I don't have proper tools for this, and we are expecting another 6 inches of snow this weekend.

Did you have suitcase weights on? Chains? Wheel weights? You should have been able to handle that snow in a straight line. My 47 inch blower eats snow like its a job

The only tool needed is a vice to straighten out the clevis (or yoke, PN 54M4422). If you don't have a vice, then you can buy a new yoke from the dealer. They are around $30, and are usually kept in stock by dealers: John Deere Yoke 54M4422

As for cotter pins, get a box of misc sizes from an auto parts store, home depot, etc. Something like this: K Tool International Cotter Pin Assortment (555-Piece)-KTI00075 - The Home Depot

It happens because this ring that keeps the pin engaged with the yoke can actually back off of the pin, and vibration then backs the pin out of the yoke.

Re: I broke the power lift mechanism on X540 today.

Is your tractor still under warranty, if so they should replace it free. If you bought the blower at the same time.

Great excuse to 'tool up"! A 24 oz. ball peen hammer and a pair of pliers at a minimum.

A vise and 3 lb. engineer hammer would be a good investment also

Re: I broke the power lift mechanism on X540 today.

You guys are absolutely correct. It is a good excuse to buy a vise table!

Just need to convince the wife so I can convert the utility room into a workshop/man cave.

Thanks for looking up the part number for me! and I agree the ring cutter pin does not look all that secure. It could wiggle out of position.

In fact, while I was looking at the problem area, I did find three other places the cutter pins looking very questionable. Basically, all 4 clevis have the same kind of pin, and 1 walked out, 3 others kind look like they could go the same way.

Well, I have chains, 4 suitcase weights, mounted on Doug's custom weight bracket. It has great traction. No problem at all. Even when I got in trouble, (one rear wheel digging into soft ground) I can always press down the diff lock, and it works wonders, it backs right out. No complaints there.

With this storm, we got maybe 14 inches of super wet sticky stuff, then followed by light rain, by the time I got out starting clearing at 4pm, the snow is kind of hard packed, and it already has a crust of ice on top. I tried to manually shove out a corner by the garage, the snow felt like solid concrete, super super heavy. I guess we call it heart attack snow for good reason.

If I taking it straight on, filling up the entire snow blower, full throttle, I can hear the engine speed slowing down dramatically like it is about to quit, but it never actually does through. It is much happier if I give it multiple passes. I feel it is probably easier on the machine doing it that way.

How is upstate NY? I figure where you are, with temperature a few degrees lower, the snow maybe a little less wet. Or maybe the constant speed governor on your X590 helps? I don't know.

Re: I broke the power lift mechanism on X540 today.

All snow here in Albany. ( all 24 inches of it) As for the Constant Speed governor, with grass and mower deck I have tried several times to bog the engine down and couldn’t do it. With the blower I can bog it down, but it takes a lot of snow, I have to go slow with packed in snow at end of driveway – even the 16 to 18 inches I did , I had to go rather slow ( 1 to 2 MPH) , to give blower time to eat and process snow.
I’ve done the wet slushy snow, but only about 6 inches and the 47inch blower had no problem with that
