How does it sound? Is it prone for hearing protection? Or have you done enough to muffle the hammering out the exhaust?I was lucky enough to find 2 Honda RT5000's and bought both, one was in great running condition and I use it to mow every week, the 2nd one did not run and had some issues. I had a donor T1600 Kubota so I started modifying the Honda to install the 2 cylinder diesel. So far I've got the engine installed and it runs and everything works on the tractor itself as far as the hydraulic lifts and PTO's. I'm working on the wiring and gauges now. some significant modifications to the drive train and new spots for the gas tank and battery will need to be made also. My thoughts were pairing the torque and HP of the diesel with the gearing of the Honda would make a great workhorse for using the push blade and box blade.
