You have 256 hours on the clock in 7 years and mow 2-3 acres at a time? Either you rarely cut your grass, or you aren't cutting 2-3 acres every week. 256 is still low hours, even for a box store. Everyone's comments is based on cutting weekly, sometimes biweekly if needed, for the entire season which is 7-8 months. If you are cutting 2-3 acres, that's 8-12 hours a month during the cutting season. You would be at close to 400 hours, if not over 500 if you are cutting 3 acres weekly. You are comparing larger acreage/less frequent actual use to the smaller/more frequent recommendation. That's not a fair comparison. The D110 works for you, great, but JD recommended the D110 for 1/3 to up to an acre for a reason. There is no doubt that because JD makes it, even the box store models should last some time, but come back here when you get into the 500 hour plus area. JD didn't recommend the D110 for over an acre for a reason. If you limited it to 1 acre, it would take over 15 years to reach 500 hours. If you triple that, you get there in 5, which is why everyone is saying "you get what you pay for" and the model shouldn't be expected to last more than 5 years at that usage. A box store model will not likely see higher hours as better models in the line up will.I have a 2012 D110. It now has 256 hours on it, and mows 2-3 flat acres, between my place and the neighbors'. Other than lube, oil, filters, and blades, it has had --0-- issues. The hood is scratched some from the low branches. I picked up a replacement upper hood for $26 on Ebay. When I get to cutting the offending vegetation, I'll swap that out. That's it. Belts are all original. I did replace the front wheel bushings with bearings as preventive maintenance.
Box store machines do last if they are not abused.
This one fits my "needs" - notice I didn't say "wants" - just fine.
