Cub 1200 implement lift handle
 

Hello all-

Just purchased a Cub 1200 for my son to mow with. Had to replace the three-pin driven disc for the clutch, but it otherwise runs out well and has a very quiet (though perforated) cutting deck.

Problem--The implement lift arm does not seem to be working right. The arm, unlike other Cub models I've seen, has a second "locking button" located on the front-side of the grip. It is apparently used in conjunction with the adjustable deck height cam on this model.

Anyway, the locking button appears to be stuck "in" somehow, and I can't get the main rod to release so that the top push button pops up all the way. The result of this is that the rod on the bottom of the lift handle is not contacting the ratchet.

Two questions--1. Is this a common problem? 2. Is this locking button (#14 in diagram) removeable/serviceable?

Thanks!

That button lets the deck "float".
It is removable/serviceable. The top button is screwed in so just unscrew it and remove spring and button.

no-go
 

The top button unscrews but it won't come out once the rod releases from it. I am thinking the small locking button has it jammed up inside.

Is the small locking button (item #14 on diagram) removeable without pulling the large/top button out first?

:Welcome2:

Have you soaked it in some PB Blaster yet?

Yes, it all works freely, but I'm thinking the small locking button is not popped out all the way, or is broken inside.

I have not seen one of these previously so it's hard to guess. I don't want to drill it out if I don't have to--

You may ,and I say may, be able to push # 9 down beyond the float button and try to disengage it. That small button is a press fit.So if it is broken you will have to remove it.Vice grips did it for me.

And it (#14) is one expensive puppy so take care .....
Happy wrenching .

No-go on pushing the top button (#9) down any further. It's hitting the mechanical stop inside, and then catching on the locking button on the way up.

We've started carefully pulling on the locking button with pliers (thanks for tip). It seems like the outer collar is deformed, but we've gotten it to pop out several mm further than it had originally. I think I'd feel more comfortable if I knew what the mechanism looked like, but almost no detail on the CC print.

Will keep you posted--

I would thought that would work but it looks like you have to replace the button.Here is a picture of one that I have.These are only $17.00

Appreciate the pictures, thank you.

My son and I were able to remove the insides from what is apparently the outer shell portion of the button earlier today (as below). This released the main/top button, and all is working now as it should (except the float feature!).

It looks like the shell had worn out at some point, and someone staked it to keep the button and all intact.


Please PM with more info on the MTD replacements--

Thanks very much to everyone for your help! :biggrin2:
