I will definitely post a picture of my machine tonight.
The HRX217HYA has the hydrostatic transmission, but it does not say whether it is belt driven or shaft. The commercial unit says (shaft drive). Obviously the commercial is made with parts that could withstand many hours, but the residential is also up to the challenge???
Also, is there an advantage to the 190 cc motor? Everything I read says the 160 is plenty powerful and the commercial units available are only 160cc?
