149 Lift Problem?
 

Hi guys, I have a 149 with a 42" plow, and it won't lift the plow more than about an inch. I can clearly see the piston has full movement range. Any ideas?

Did you check for broken spirol pins in the rockshaft?

Is your lift rod the correct length?

Jeff, the lift rod is the correct length, i don't know about the pins

There may be welds instead of spirol pins ( I have narrow frames myself ) but you should get more lift.

jeff, the pins and shaft are fine. any other ideas?

They can appear intact when in fact they are sheared.

A picture or video of the moving parts involved would be helpful.

How would i do a video? same as a picture?

Take a video then put it on youtube and copy and paste the url here.

kostendorf, I hope this helps https://www.youtube.com/watch?v=h_BwagaPO_w

Your rockshaft is moving but the lift is not . the pin is broke.

Ok. Thank you. any suggestions of where to get one?

It's a spirol pin. Not to be confused with a spring pin. They are different. You can get them from CCC, IH, a parts store or "farm store" may have them. Order them online.... from Cub Cadet, McMaster Carr.... lots of places. :beerchug:

Hardware store, auto parts store, local Cub/Deere/etc. dealer, lawnmower repair shop, another garden tractor (but I would just buy new ones rather than used)..

One of the sponsors at the top of the page or google it. Spirol Coil pin . they come in 1/4x 1 1/8" - 1/4x 1 1/4" - 1/4x 1 1/2" - 1/4x 2"

There has been a lot of post recently about how to get them out and replacing them.

I didn't watch your vid but if it's the pin on the outside of the frame that holds the triangle plate on it is a 5/16" spiral pin, you most likely won't find it at your local hardware store.

Check with out sponsors at the top of the page, or you can order a package of 5 or 10 from McMaster Carr.

Guys, I appreciate all the help. It is 11 here in Mi, and we are having the annual snowpocalapse. Seeing as to the fact that it needed an immediate fix, I stuck a 3/8x1" bolt in it and a couple of lock washers. should get one plowing in before I make it into town.

You'll shear it before you get anything done.... Sorry, but a bolt is just not strong enough....

Well then, its just gonna shear. I am Not getting back into that greasy tractor again until I have the part. Oh well. It was worth the try.

I think you all need to watch the video again. It appears to be missing one of the two bolts that hold the lift extension on( or whatever its called) you can see it pivoting on the one bolt but there should be 2 and you can clearly see its missing.

Use a clevis pin in the second hole. There is no down pressure. Looks like the rock shaft is not moving much. If you look it's pivoting in the middle.

You nailed it Tim. Good eye. I did not see it until you stated it. I know my lift will not work without something in both holes.

Tim the upper bolt is to lock out the float, unnecessary for lifting. If you watch the video his deck arm is stuck almost all the way up, yet the blade is still on the ground. You can see small movement of the deck lift arm at the upper end of cylinder travel, but the outer lift arm bracket is not moving as much. There is a disconnect on the rock shaft somewhere, one of the pins is broke.

Bob, if yours will only go up and down with 2 pins, I suspect the rock shaft is half rusted and not moving freely. It should go up and down with just the bottom pin in place.

Here is a pic of my lift arm extension, only the bottom bolt is needed like in the op's machine. Pay no attention to the bar in the background.

OK that makes sense, I've never seen one that didn't have both pins.

More than likely the outer rockshaft pin is sheared. Yes, the second hole is for down pressure. It is not needed. The reason that it is rocking of the second pin is because the blade is already on the ground. It is also possible that the lift rod to the blade is too long. Fix the broken pin to know for sure. You can test with the bolt that you put in. As long as no other pins are sheared.....

Berwil,
My tractor will lift with just one pin in the bottom but there is a lot of play due to pin holes being worn after 40 some years. Also the floating piece that the pin goes through has a lot of wear at the angle part as it fits to the other bar. I get about 3 more inches of lift up front by using 2 bolts as this took all the play out of it. I then use a chain to front implements to keep from damaging the hyd. system. My rock shaft and pins are in reasonably good shape. Thanks for your input though and I believe that you are correct in your assessment of the op's lifting problem. Have a great day all.
