B&S engine choice delima
I'm trying to decide between these 2 B&S V-twin engines. The "Professional grade" 24hp, 724cc, model 44M777, type 0790 B1, code 100 126YC. And the "Platinum" 24hp, 724cc, XRD series, model 445677, type 2188 G1, code 101019YG. Per the sears ecatalog viewer flash brochure the main selling points of the professional engine compared to the platinum seems to be the pro has a superpolished "ride" bearing for longer life. Not sure what bearing this is, maybe the engine main bearing? It also has a chrome polated exhaust value for longer life & mechanical compression release for easier starting. I think both engines are still "consumer grade"?? Which is probably fine for the .75 acre I'm mowing but since they come on different mowers:
model 247.289800 and 917.288570 I'm trying to get the best for long term. I tried to include html links to the two mowers but it became jumbled. Their easy to find off the craftsman website its the PYT9000 w/42 inch cut and off sears.com its the 288570 w/46 inch cut.
Which engine do you prefer and why? Thanks!
