I was looking at the like mower(vs Toro Estate) by Exmark the model CT. Their 48" unit has a twin cylinder Briggs Vanguard 18HP. What is the torque for that model? ( Here comes a dumb question) Is torque and displacement the same thing? If so the Briggs has a displacement of 34.8. How does this engine compare to the 19hp Kawi which has 37.0 of torque that is on the Toro Estate mower? My point in the question is. All I want is the 48" deck mower so I can get it through my back gate. The Toro estate 48" has a single cylinder Kohler which the dealer said is underpowered for that unit. So that puts me with the 52" Toro with Kawi 19hp twin. Now I see the Exmark 48" (same as Toro for the most part) has the twin Briggs. Am I spiting hairs here? Are they about the same in the end?
