To make things a little more clear...the flywheel on the unit im looking at was changed not the engine.
I'm "old school" and don't want to buy "box store". I might feel different if todays stuff was as good as my lt180 deere tractor. 12 yrs old 230 hours...everything original. Never tossed a belt...all belts still look great...blades get sharpened 2x's a year and look like they'll go 12 more cause they just need a "touch" on the grinder. Not a pulley or brg out anywhere...no strange vibrations. I set the tractor to carry the deck off the ground...just touching the high spots. Mows sweet.
Funny thing is my tractor was considered "junk" compared to the older deeres.
Really makes me scratch my head when I read about today's "builds". Maybe the difference was the internet didn't have so many "stories" years ago to scare buyers?
