I ran a ferris with the 3 cylinder 31 0r 33hp cat diesel is 5100. It was a useless piece of crap. Blade tip speed would drop just from from driving the machine. When cutting it would only mow at half speed if that in heavy grass. I loved the ride but the machine was way under powered. It needs a turbo in my opinion. I would like to try the Dixie Chopper or Bad boy as they use a 4 cylinder cat engine. I just dont understand why they are not putting turbos on these small diesel engines?
My z 970 with 37 hp gets 1.8gph but it cuts twice as fast as that ferris plus I paying a guy twice the labor if I buy a diesel. Dixie Chopper had a turbo Diesel that was 50hp but that mower was out dated.
