Repair advice for MTD Yardman deck frame where 3.75hp B&S mounts

Hi everyone,
Does anyone have a good way to repair the engine mounting area on the push mower deck when cracks start on top where the engine bolts on? I have an old MTD Yardman mower with a 3.75hp B&S engine that runs/starts great and I'd like to repair it to get a few more years of service. Deck frames don't seem to made as well or as thick as they once were and in fact I damaged a Weedeater 500 push mower a couple of years ago, to where the only way I fixed that was to cut-out a mounting 'circle' from a old deck frame and weld it onto the Weedeater deck after cutting out the busted mounting holes.

I've been looking for some kind of flat-steel 'ring' with the opening diameter of the mower's deck opening, where all I would have to do is drill the engine mounting holes to match the frame and then bolting that onto the good-part of the deck - maybe sandwiching in some steel-epoxy. So far though, I've not found anything that matches the 8" opening of the deck.

Thought I'd post here to see if anyone had come up with the right components or a better solution.

Have any local Welders who could tackle that job permanently . . . . if you just brought in the clean shell?

I just weld them back up and fix the vibration. If it's cracking that much, something is probably out of balance or bent, causing a bit more vibration than it can handle.

I have an older Craftsman self propelled from my neighbor that has the same issue.

I thought about the same thing with a ring with the bolt holes to repair it.

If a machine shop were to stamp some out like that it would be good !!!

It is a common thing to happen ~!~!
