Just couldn't resist...3 hr trip one way yesterday... WELL worth the trip... let's just say I got everything for less than 6 new grates :-)... everything in super nice shape...came apart easily.

Did the same very recently. In my case the boiler is likely scrap yard material but everything else is in great condition.

Clean it up, store it away on the shelf. Someday you will be glad you did.

That my friend, is why I did it. :-)

Although this pot and auger is in much better condition than what I'm running now...so I can see a swap out in the spring :-)

That's a great idea of having a back up pot and auger. I think it will clean up nice. The grates look pretty good too.

The ratchet mechanism ...or should I say where the arm is attached to the gear box is different...instead of the slide that goes over the ratchet gear to adjust feed rate you move the pivot point on a small slotted arm that is attached to the gear box. Can someone date this?

That is the older design, but I don't know the date when they went to the newer method of the sliding shield on the ratchet. Also the older units had a larger gear reducer.
Mine is kind of a hybrid so to speak. It has the feed adjustment on the ratchet, but it also has the older gearbox with the slotted adjustment for the feed. So I guess I could probably go to 15 teeth on the feed? LOL. I run it at 3 in the summer and 4 in the winter.
