OK :beerchug:

X2 he is talking about the subframe. That way when you whack something hard under the snow that ya don't see you'll feel it throughout the whole tractor centering under your feet where the rockshaft is. Another thing to remember is to keep the blade unlocked so it can trip if and when that happens.

Maybe I'm misunderstanding; I'm a visual learner. Can you show me a pic of what you're referring to? Circle the item so I can't miss it.

Concur on the unlocked position of the blade.

I have ended up on the hood of my (modified, many times) 72.
It is truly true, don't forget to unlock the blade release. ;) :beerchug:

Update
 

Well, we finally had enough snow to push on Wednesday of this week. The 782 did great on downhill and level areas, no so much on uphill areas when a big snow was being pushed. All that without chains. Was hoping the super aggressive tire tread would be good enough to not install the chains.

Had a neighbor call last night wanting her driveway pushed. So went out early this morning (10 deg F) and installed chains. Opened the gas valve, pulled the choke and it fired up on the 3rd try. I erroneously pushed in the choke too early and it died. After that, all I could get was a clicking sound from the solenoid. Sounded like battery was too low, but it wasn't. Put a jump on it and still clicking. Think the solenoid is stuck or bad. Had to call my neighbor and apologize for not being able to get it done.

The hydraulically actuated blade worked great though. Will get this thing running again and just put chains on in early winter to stay on all winter.

I would suggestion that you check both Battery Cables, on each end, that they are clean, brite, and tight.

Ditto on the connections, same thing happened with my 1872. I put a charger on the battery and it wouldn't pull any amps, the battery was full charged, the terminals were loose, it was starting good until I really needed it. I had just purchased mine also. Easy fix.

Good suggestion, Roland. I'll get back out there when the temps are a little warmer and check 'em out. Will let you know...

Checked all the electrical connections (including grounds) and made sure they were clean and bright. No issues there.

Each time I turned the key to the start position, I could hear the solenoid click and then a high pitched whine. I ordered a new solenoid anyway, just to eliminate that as a possibility. If that's not the culprit, then I can put the old solenoid back on and look somewhere else.

Will keep you posted. New solenoid is to be delivered on Thursday. Thanks.

I thought the same, until I saw the OP was in MO :D
