I just traded a 335/54C with 540 hours which has the same air-cooled Kaw motor. My only complaint is fuel economy, 1.5-2 gallons an hour when pulled hard. The motor is very strong, however, just thirsty. Handles the tiller, snowblower and 54C with ease. I would definitely get the bigger deck, only 6" wider and the added width makes it easier to get close to/under trees, etc and the pivot wheels make removal and installation quick and easy.
