For riders I like Deere but love Simplicity. Being in Wi i have good access to both. I will say i havent found anyone better than Deere parts network but didnt stop me from buying a simplicity.
I agree here. I have 3+ acres of lawn which I mow twice per week and twice per cut so I can counter-stripe, 100+ hr per yr mowing... My 1972 Simplicity Power-Max 4041 with the 60 inch fairway deck is an absolute monster that no modern "lawn" or "garden tractor" can even remotely hold a candle to (you have to own one to know...)
But I do my regular mowing with a cheap JD 335 zero turn from Lowes.
It's like if I had a 1970 Chevelle LS6 454, I wouldn't commute to work in it, I'd drive a Ford Focus. Both will get you to work, but who wants to wear out their bad-*** Chevelle driving to work when a Focus gets you there just fine. Once the Focus is toast, who cares, it's a Ford Focus, get another one. The 4041 is the lawnmower equivalent of the Chevelle. It will always be fixable and rebuildable even if it gets expensive, and it will easily outlive me. All the good American brands of the era had a similar high-quality unit. The 4041 comes out before I have a bunch of people over for a party, and I want perfect basketweave stripes in the lawn like a baseball diamond.
The Focus is the lawnmower equivalent of everything made in the last 20 years costing less than $20k. I'm on my third similar cheap mower purchased brand new, and get about 5-6 well-maintained years or 400-600 hours out of them before the non-servicable transaxles are tired, the spindles are sloppy, the low-grade B&S or Kohler engine is tired, but it's still worth ~$700 on Craigslist which I put towards a ~$3000 new unit. For regular mowing I say get the cheap unit and wear it out. To show off or as a hobby get a quality 30-50 year old American unit and fix it up/keep it running, but not for regular mowing.
