In a small tractor a diesel will give you half the fuel consumption and probably four times the engine life. The little diesels in tractors can easily go 10,000 hours if properly cared for.
Not to attack diesel engines but todays small gas engines do not have the power of a Model A engine, or the weight of that four cylinder engine's crankshaft with a heavy flywheel to give the match the Ford's Model A engine for torque.
Those not old enough to know Fords tractor engine was basically the Model A engine for many years past WWII.
