Glad to see some other Gravely owners on here. Upstate NY winters can be a real pain in the Syracuse area, but my "snow-tank" does just fine. Here's my Gravely 816 in her winter running gear:
I picked up the cab and 4' blower this winter on Craislist, $550 for both! The cab is actually made for a 8000 series, but the only difference is that it's a little longer and a couple mounts don't line up. Not a big problem to overcome. The blower is great - I was running a 2 stage 38" before, and my wheels are 42" wide, so I would lose traction. The 48" is great!
The tractor itself is a 1975 (I think) with hydraulics that originally had a 16hp in it, but somewhere in its lifetime it was replaced with a Kohler M18 Magnum (18hp dual cylinder) which is a nice upgrade. I also have a 50" mower deck for it, and my Father in Law has several riders, walk behinds, and just about every attachment known to Gravely. This tractor was actually a housewarming present from him. It was the first rider he'd ever worked on, and since then he's bought a few more riders since he was so impressed with this one! I'm hoping he'll give me a walk behind for clearing the sidewalks and some brushhog work!
Here's the new blower without the cab on it:
And here's the driveway I have to keep clear:
(The trailer is a 8x14, for size reference)
Since I got the cab, the heat from the motor keeps me nice and warm when clearing snow. I don't mind doing it at all anymore, and usually end up clearing every square inch of snow I can!
