Does anyone know for certain whether the Frontier RT1173 is gear or chain driven? I am working on the purchase of a 4066R along with the RT1173. The dealer told me it was gear driven (he looked online at the brochure - see below). BUT, the manual I read on the internet says it is chain driven. I tend to believe the manual. I would rather stay away from a chain drive as I plan to till several acres with it. See pictures for conflicting info - the "Technical Specifications" is taken from the Frontier manual for the RT-1173 - there are several references in the manual to the tiller being chain driven.
