I think its crazy to pay for more than 2,000 for a machine to mow lawns unless you making money using it. I paid 1600 for my Husqvarna on 2006, I have 500 hours on it, and only replaced the mandrel bearings once and the mower deck belt once. I have gone through three batteries so far and it still runs great and burns no oil. Thats 1600 dollars....for a machine you use in Maine for 4 to 5 months a year.
I would be absolutely bonkers to spend 4000 or more on one of these just to mow a lawn. More expense machines are just that..more expensive.
I use my diesel tractor for everything else...should last me rest of my life or as long as I still need it. Wont even buy a deck for it cause my Husqvarna was cheaper than the mmm deck for this.
