Hi Norm & hi Tyler,
Norm, do you blank it off then? If so, How and why?
Isn't it better to have the engine increase as it encounters tall grass, or is the system too temperamental and you prefer to increase revs yourself using the throttle?
I used a late model Powertorque (10 years old or so) in someone's lawn and the governor was working well as the engine kept constant revs really well as it hit thicker grass.
