I've had a green 38", 14 horse, JD lawn mower for 22 years. Cut 3 1/2 acres every week during grass season and then a little bit of other use. Never had a problem with the "Cowey-Sockey" engine...never had the spark plug out of it....never touched the engine and it still cranks quickly, doesn't use any oil between annual changes, just great. It was a higher dollar, more sturdy, heavier built than the usual JD lawn mower when I bought it. The mower deck was twice as thick as the other cheaper models, the frame was heavier as was the front axle. The blade spindles were greaseable and I greased them regularly.
Here's what I've had to do to it. About 5 years ago, I had to put tubes in all the tires. They had gotten so old and rotten they wouldn't stay inflated between cuttings. Two years ago after 20 years of use, one blade spindle went bad, the heavy deck was still good, so I spent $200 for new pulley/spindles, belts and blades.....cut like new......quiet as could be.....then the old plastic parts started breaking up. First was the blade switch....now, I just stick my finger down in the hole that's left to engage the blade. Then the plastic throttle handle broke, so I screwed a piece of wood to it.....then the plastic brake lock that keeps the parking off broke so, I wired that up with some single strand copper wire...then while I was raising the plastic hood to fix the brake lock problem....it broke and fell off....looks bad without a hood but still works just fine without a hood....then the spring thingy, where ever it is, that locks the blade lift mechanism up broke and I haven't devised a redneck, poor white trash fix for that yet.
SO LAST WEEK I BOUGHT A NEW MOWER....an orange "husky-Vonner" zero turn with a 24 horse "Cowey-Sockey" engine and a heavy duty, greaseable, fabricated deck. I could have bought a Cub Cadet for a couple thousand less with a "Colder" engine and tin deck but I bought one that I hope will last until I need the grass cut over my grave. I am now having just a bit of buyers remorse....wish I had just went on and spent a couple more thousand for a FERRIS.
