Honda makes a good mower too.
Briggs never die.
If you get a self propelled, get one with a full width lever handle, just like the deadman switch, not the little handle like the clutch lever on a motorcycle.
Look at the wheels. Cheaper mowers have plastic hubs on the wheels. Better mowers have metal hubs.
Do you want a mulcher that can discharge too?
Do you want a mulcher that can take a bag?
Honda has come out with a dual blade mower, supposed to be better for mulching.
Current lawnboys and toro's are no better than any other mower on the market, unlike the old 2-cycle versions that were the BEST.
You do not need to get the mower with the built in fuel stabilizer gas cap. Just get the standard mower and add Sta-bil to every can of gas you buy.
My mower that I bought at Home Depot starts 2nd pull every spring and then 1st pull after that till I put it away in the fall (Briggs motor).
The mower that I keep down by the stormwater pond (yardsale mower my father-in-law gave me 10+ years ago) starts 2nd or 3rd pull every spring and 1st or second pull after that. It stays outside, no cover, deck cleaned in the fall only when put away for the winter, air filter changed once since I've had it (last year), same for the engine oil. (briggs motor)
Don't get a Tecumseh motor.
