Cub Cadet, hydro power down pressure ?

jr1712 · #1 11-01-2013, 07:54 PM

The lift cylinder for the deck also powers the front blade. The blade does not have and power down. I took the cover off and found the lift arm just hits the bracket when going up, then rotates free when going down. It looks like their is a spot to put a bolt through with a nut welded to the lift arm to lock it.

Just wondering if that,s what it,s for.

YUP, I guess you can say, the hydro system, by default, is "free float". IF....you want down pressure, you will have to install the "locking pin".

That's what I thought, is it just a single bolt with a collar on it? Do you have any pictures of it? Thanks for the info

You need to be careful when putting the lock pin in I have seen this bend what is # 2 in the diagram. It is not very easy to get out and straighten. I have also seen the roll pins snap and this is also not a quick fix.

I had the same idea you have on my dual stick 1650 when I got the push blade. I think I asked the same question you're asking, I also got the same advise about being careful or I may break or bend something.
But being the thick headed person I am I went ahead and locked it in for down pressure. Worked great for a little while till I snapped the spirol pin. It is a bugger to change.
Lesson learned

So coming from someone who's been there, done that, be carful while applying down pressure.

I just finally found the manual. I think the lift bar for the rear 3 pt attaches hear, but you also have the option to have power down on front attachments when the bolt is in . I went out and put a bolt in to lock it and the lift bar for the front blade bows out when powering down. I think that's the part that will fail/flex before a roll pin brakes.

Think again. Spirol pin is a pita to change, your tractor, your fix.

Yep one of the most fun jobs on a Cub is changing the spirol pins in the rock shaft. you get to use lot's of cool tools like a cutting torch, BIG hammers and you also get you use a lot of great 4 letter words. Let us know how that works out for you.

I used a bolt to "Power down" when using my Johnny bucket but I realized that the little pin on the rock shaft was where all the stress is and not the grade "8" bolt I used. All I can say is that if you really want to have a reliable power down system you would need to weld the arm to the shaft.

Thanks for the info on the roll pin and past experience.
