I demo'd ome last summer in the 100* heat without rain for weeks. The city let the dealer take one to a park and we messed with it until I got too hot and left them to it. The ride on Toro jobby was pulling about a 2" plug. I love my Ryan Lawnair but I don't think it would have pulled plugs on that dry field like that. It was a nice ride too and had fancy gauges and lots of bells and such. For the 8K or whatever it was I don't have the work to justify that.
