2 strokes have their own torque characteristics- as a general statement subject to dispute- a slightly narrower peak power range and slight less torque curve. Note that peak power can be higher for weight and displacement of engine as compared to 4stroke. As for a 2 stroke in H- are you thinking of a Rotax snowmobile engine or a GMC 2-71? GMC 2 cyl 2stroke would be about like a JD 430(?) from factory. Olivers hade a big tractor with a GMC4-53 about 100hp range (1655?) with good reputation. Cousins in-laws have a White with a 3 cylinder GMC 3-71 I think that they use as large utility/medium field use -thes are linear flow designs with overhead exhaust valves, compressors, diesels. Gas engine 2stroke tractors with piston port time loop scavenged design? Garden tractors maybe- ILO, Sachs, Rotax engines had industrial/agricultural use advertised, I have seen tillers and lawntractor advertised with 2 strokes now, some about 20 year old garden tractors maybe? . Snowmobile engines used in hotrod garden tractors for drag raceing, pulling exhibitions known- actual garden plowing and cultivating ?? What engine do you have in mind? RN
