I would stick with a rider mower or a tractor with a mower. Those commercial mowers with very tight turning radius are murder on your back, imho.
The advantage of a real commercial mower is the blades turn at a higher speed than your typical John Deere rider. This allows you to mow at a higher velocity. Therefore, completing the mowing in 1/2 to 2/3 the time. They also have heavy duty hydraulic pumps 8-10 gauge fabricated decks.
Again, I am not talking about a John Deere, Ariens, Toro, Cub Cadet or Gravely zero turn mower. These machines are made for homeowners to cut their 1/2 acre lawn. I am looking to buy a machine that originally sold for 11K-13K. Made for some landscaper to beat the crap out of and put 6+ machine hours per day on the engine.
The reason I am looking for a 52” deck as opposed to a 60” deck is that there are places on my property I could not get a 60” mower plus the side shoot into. Therefore, I would then have to trim with a smaller machine. Which defeats the purpose.
