Like you all said, this G.A.S. happens fast. First I just wanted the tractor. Now a plow pops up and of course it’d be handy to have. Then I see a front PTO with adapter kit, and that sure would be nice to have too. Then I could get a brush cutter and really do some damage. But wait, the cost of that front PTO and brush cutter might be the same or more than just buying a walk behind with a brush cutter. Plus I wouldn’t have to mess with swapping stuff around if I also had a walk behind. But that front PTO seems too good to pass up. What to do, what to do. All I wanted was something to mow with. That was it.
Yep. G.A.S. :)

BTW you want that front adapter for other things. A walker is better for brush hogging anyway, but with that front kit, you can get a small deck into the tight places you can't reach with a belly deck. To really go hog wild, you could get a gang reel mower to mount on either the front of the walker, or the adapter on the rider. Of course, you'd need the gang mower. Better start looking. . . . .

Did we mention that we're all enablers?

kyavion, I checked the air filter baseplate on my '72 816 today. Guess what, no hole just like yours. I can't say where it should go either since the tractor (a non running $200 special) is sitting like it was when I picked it up, and there is no breather hose at all. The breather hose on the '75 816 *does* press fit into a hole on the underside of the baseplate.

Maybe someone with a 72-73 816 can take a look and let you know where their breather hose winds up.

The breather hose on my '74 is like Dave's. I suspect somebody swapped parts around.

For the short term, I wouldn't worry about it. You can run it with that hose disconnected. You could stuff a bit of fiberglass or something in the end of the hose to keep crud from getting in there.

With a serial of 15896A that would mean the tractor does have an LSD axle. LSD's were no longer installed mid-way through the 73' MY, around the 18xxx serial.

On the axle hubs, the one set screw doesn't look to be a set screw, instead it appears to have been replaced by a common bolt. You'll want to replace that bolt witha proper set screw as bolt don't have the necessary properties to function as a set screw. Verify that both set screws are tight down on their axle keys, otherwise you'll wear out the key ways in the hubs. The in/out play of the rear axles is normal, and I wouldn't be concerned the separate play of the wheel in all directions. The bearings on the axles are very robust and bathed in oil.

I don't have time to read every thing in this thread at the moment. I did read your concerns about the 30 Bush hog deck taking longer to cut what you need to cut. I think you might be surprised . The walking tractors are nible to use the 30 inch deck will get places you can't get to with bigger decks. I have about 1/2 acre of yard that it cut up with garden fire pit trees etc. I can cut it with my professional 12 and a 40 inch deck in about 2/3rds the time it takes with a 46 inch deck on a rider . My professional 12 walking tractor has steering brakes and is nearly as maneuverable as a zero turn

Thanks for the info about the walk behinds. I may have to look into getting one down the road.

I picked up that snow blade yesterday. I stopped by Richard’s in WV since I was close by, and he said it looked looked like all the blade parts were there and it looked good to go. I showed him a pic of the breather hose, and he didn’t have much to say about it. He said he had only seen a couple Onan’s before. Another person there said it was just a vent for combustion gases, and that they probably starting attaching the hose to the air filter for emission regulations. He recommended just getting a vented cap for it.

I guess I lucked out with getting the LSD. Thanks for the info for that.

As far as the set screw, how would the end be different from a bolt? Is it something I can shape with a grinder?

Now how about these wheel weights? They sure are pricey. Do 15lb weights really make that much of a difference? What about just added weight on top of the blade, or just attaching weight to a rod that goes through the front PTO hole?

It's not so much weight on the blade that you need, but weight for the front end of the tractor so the steering wheels do not lift off the ground as readily. Rather than wheel weights, you can look for a front mount weight rack and then you can be creative with what you use for the weight (still $$$, probably). I think there is clearance for the plow with the rack installed (perhaps others can confirm).

So I haven’t had a chance to use my Gravely on my property yet. Things have been really busy lately, but after Thanksgiving I’ll have a chance to do a final cut and push some dirt into some open trenches that were for septic and electric.

From reading online, I’m a little concerned about running today’s gas in the Gravely, and ethanol free gas is hard to find. I purchased some of this: https://www.amazon.com/DRIVEN-Carb-Defender-Fuel-Additive/dp/B00G3DRNZ8/ref=mp_s_a_1_1?adgrpid=61745179371&gclid=Cj0KCQiA2ITuBRDkARIsAMK9Q7PDB3QVi0QTJXtCc7BRxv-ec3M88ZjfJyYKqSY7Drm4VUdrJE92yKEaAnK-EALw_wcB&hvadid=274839110832&hvdev=m&hvlocphy=9014439&hvnetw=g&hvpos=1t1&hvqmt=e&hvrand=79229154207856587&hvtargid=kwd-400329814074&hydadcr=12164_10197800&keywords=driven+carb+defender&qid=1572959691&sr=8-1

Any other recommendations? I plan on adding a small trickle charger to the battery. What about a magnetic oil heater? Is that a good idea too?

The fuel additive sounds interesting. I should probably be using something like this myself. An oil heater might be a good idea too if it gets very cold where you are, and you're planning on having to use the tractor for plowing snow the next morning, etc.
