Thanks for the input. You're pretty much confirming my suspicions. I was just curious since the D and LA series are actually specifically listed as supported models on the Johnny bucket website. I really didn't plan on doing much "ground engagement" work, but rather more moving and spreading type of work with landscape stone and mulch and such.
I'm still curious though if anyone has actually made the jump and trusted their website and bought one for these small mowers. I'd be interested to hear the experience.
