Because my neighbors see my Ferris 1500IS they bring me their mowers for odds and ends of maintenance. My next door neighbor has had her Z4200 in the shop for lots of work. I took over some of the minor work as she's a single mom trying to get back on her feet after booting an abusive drunk husband. The 4200 has a really cheap deck and spindles, Everything, and I mean everything, is very difficult to get at for PM. The Briggs motor isn't worth beans either. The hydros have barely enough response to move the thing left, right and forward It's only 3 yrs old and the local repair shop (Not a dealer) has really ripped her off. I hate when businessmen rip off women for major repairs when they aren't needed. I tell her all the time to get rid of the junk that drunk ole man of hers bought and buy a real mower that'll last long passed this thing.
Long story shortened...I'll never go back to homeowner machines again. Heavier decks, better engineering in the motors, much better hydro pumps, thicker blades, higher blade tip speed...The list just goes on and on. Spend another grand and never buy another mower in your life. Worst case scenario...you sell the mower when you sell the property, usually for the same amount you payed for it, too.
