Year is up in 2 days, showing 331 hours, but haven't used it much in the last two months while I work on a remodeling project. Just fired it up today for the first time in about 3 weeks, used it as a portable scaffold while putting on Tyvek wrap and HardiPlank siding.
Before I bought it, I didn't have clue how much I'd use it, but I'm not surprised. Anticipate using it 400 - 500 hours in the next year; at least 300 hours per year after that.
Don't have any grass to mow, yet, may never use it for finish mowing (also have a couple of yard tractors). Have done some brush hogging.
