I was informed that the 36 was discontinued; and, I was offered a 48SOT-BS25 for the same price/conditions.
I took that deal; and WOW! This mower was Heavily crated=metal all the way! [400 pounds of metal/5 pounds of plastic wrap] Mower is supposed to weight 650 lbs. Total shipped weight was 1,055 lbs. According to UPS.
Because of too much rain/soft yard; I have only operated the 48SOT for a few minutes. I really LIKE the easy controls.
Thanks to: Havener/Bradley/SLE I now have a pro mower that looks as if it will last for decades.
