Hi guys I picked up a gravely 812 with fully functional deck and pto. She needs some TLC but I'll be using her regularly engine starts and runs well.

Anyway to tell the year it was made? I seen a serial number on the deck but not sure about the tractor?

Welcome

The serial number would be on a silver tag underneath the dash, left side.
On an early 812 it could be on the engine adapter plate. I have had them in both location.

It appears you have a mower deck newer than the tractor. If I am reading your picture right, it has top mounted zerks with the access hole in the belt covers. That's a good thing.

Welcome, and congratulations on your 812 northcoast! My guess would be that the serial number is on the engine adapter plate, since your tractor looks to be an older one like mine. You should see it looking downward just forward of the engine between the engine, and transmission. If you don't see it right away, check closely to be sure that it wasn't painted over at some point.

I'm a dope its below the dash. I was looking in all the wrong places when it was right under my nose lol.

So can the serial tell the year of the deck and tractor?

It's at least a 75' or later model tractor, judging by the rod based parking brake and the rack/pinion steering. The deck is also period correct for the tractor, Gravely had top grease spindles installed on the decks in the mid 70's range, so it's likely the original deck.

Great. The center spindle is just a tight area to grease? Or the spindle itself is tight and doesn't spin freely?

i was just tight all the spindles spin freely. i had to grab and turn the fitting so i could get my gun in there.

i it wasn't running the best and the main and idle jet were way off i set them back to stock and it seems to be running better.

i also wiped it down with some DE-greaser man this old girl cleaned up well.

I would say it looks like a 77'. I can't tell what the 2nd number in the tractor serial is, looks like an 8. That would make it a 77'. Even if it was a 0 than that would make it a 75'. The deck serial reads as a 77' so I expect the 2nd digit in the tractor serial is in fact an 8.

Man I put this thing through its paces for the first time after going over everything.


Man it's a beast I cut my lawn in high 3rd gear it's pretty darn fast and cuts well at that speed which was really eye opening.

It makes my little John deere stx38 look like a toy mower compared.
