Don't forget Torque...Most "heavy work" engines such as tractors have a longer stroke,run at half the speed of an equal displacement automotive engine and are designed to operate,basically within a fairly narrow"powerband"(RPMs),or working RPM where they generate the most efficient"work" and fuel efficency. Having trouble explaining what I'm try to say,but kinda...A longstroke engine delivers more torque to the crank,like a long wrench delivers more leverage to a stuck fastener.The lower RPM translates to less cylinder charges of fuel burned,lowering fuel use...then after the "flywheel" TORQUE,up to the breaking strength of driveline components is manipulated within the transmission(lower gear-more torque),higher(road gears)less torque-more speed,AND Torque also figures in at differential gearing,wheel diameter,and somewhat even at drive tire size/weight.....clears as mud?Right?
