This is a great residential mower that I'd recommend for .25-2.5 acres. In my opinion it is a well rounded machine that will last for many years if it isn't abused and accurately maintained per the schedule.
As with any tool, if you purchase one that isnt big enough for the job or you do not follow the advised maintenance, it will fail at an advanced rate. Unfortunately that is how 95% of products get a bad rep.
All enterprise level companies spend serious money on research to make sure there product performs as listed and not a lick more, like back in the olden days.
