The dealer I was talking to didn't participate in the NP pricing program but the Toro rep was there and said he could get it through to Toro corporate. He also said that the piece of equipment being purchased had to match the size of the NP account. So a 4000sq ft lot wouldn't justify a 60' mower. He also mentioned that the mower had to be used 'exclusively' for that account but quickly followed by saying that it's nearly impossible to enforce.
Regarding the equipment:
He told me Toro spindles are far superior to Exmark and the Turbo Force deck is better than the deck on the Exmark. (Grandstand vs. Vantage) A little Toro rep talk there and I'm guessing some truth too. I don't know.
