My neighbor has a friend with a Yazoo.... I'll get with him to get it back here so I can take a pic..... I remember those when I was in elementary school... 3 of them on the schools grounds cutting grass at all times....

We had a Yazoo Dealer and Snapper dealer in our town.....

cpuris,

I sure did, got side tracked with the non existent grains in the aluminum used.

There are two sealed bearings, in a sleeve with a concave slot, dead center.



Has an allen head screw with a pointed end, block is drilled and tapped. Screw sets and locates the bearing housing and shaft. Preventing horizontal movement of same.

Everytime I use my old Murray's, ( 13-14) yrs. old ) I'm glad I bought used, .. and rebuilt them, learned a lot, cried a lot, but the trip is always a good one, shame they don't build em like back in 50's & 60's ..... My dad had about a 50's model Jacobsen Lawn-Queen, reel-type gas mower, THAT thing was grenade-proof !! Here's a link to one restored, .. AHhhhh memories !! .. :thumbsup:

Cut my first lawn with a Briggs and Station reel-type, 50's, were touted as a good quality mower. The reel-types, always produced a clean & consistent grass hight or depth. Like the Yazoo and what I like so much about the mower. Looking over the yard, it flows out like a carpet.

And no not a yard nitpicker......

I do prefer a self-powered walk behind over a ride around. Have an acre can cut it in just under and hour. To me the walk behind is more maneuverable and therefor cuts the mowing time.

Well actually the aluminium block does have a grain, but you will need to polish it to at least 600 grit then acid etch it to see it.
If it was cold extruded then you will also need a good strong magnifier.

This is going off the thread I know, but I to prefer the good old self-powered walk behinds compared to today's gentleman's toy's....

Sorry Admin.....had to say it...!

My Dad's first mower had a horizontal shaft Clinton engine with a twisted belt drive spinning a circular steel disk with blades from a sickle bar mower attached to it.

The thing was HEAVY but I like the idea of the sickle bar blades on the disk. I don't remember how they were attached. On a sickle bar, they're riveted.

An interesting amazon story, truth be known, the last place I look for parts.The jack shaft repair, working flawlessly. Last spring hear what sounds like a bearing failing, Shaft, hub #35. Lubed them having access from under the 2 grove pulley.

As any knowns parts for the Yazoo are pretty much unavaliable, easy 90%. Stumbled onto some listings for some part, of all places amazon? Useing the Yazoo bearing number, boom to my supprise... score.

It gets better, have the mower in the air, working my way in for access to the bearings. Pull the blad and find, it was not the bearing.

It was what is called a blade adapter #32, had shattered and was destructing. Thinking this could be a real problem, about 30% of it was chunks, scraping in the housing, hence the failing bearing noise.

Cleaned out the chunks, look closely, considering the possibility and damage that might occur down the road. And what snow balls chance in hell that I could find this, a bronze casting.

Finding the bearing, gave amazon another shot .............. blow me away they had about a dozen, so got 2.
