A few weeks ago. Judging by the junk in his yards his blade is in terrible
shape with all the rocks and bricks in it.

As you can see, there are many possible reasons.
Some more:
Type of grass is another, thickness of the grass, moisture content,
height, Self-propelled vs non-self propelled, how the HP is rated. I
am not sure, but some MAY measure with blade on, other may measure
with blade off. Short stroke HP vs a motor with a longer stroke,
weight of flywheel and I am sure there are other factors.

Horsepower is not torque. Your 6.75 has less torque.

Sharpness of Blade difference?...Size of blade difference? Design of blade
difference? Depth of cut setting? Design of mower deck difference? I'd check
those out first before I started... I had a very expensive Huskvarna (HAD)
and it had a larger Briggs & Statton motor than my father in-laws Sears
Briggs & Stratton...I couldn't even think of keeping up with the father in
laws machine... Both garden tractors with the same cutting width...I really
think design has a lot to do with it...That Sears tractor could not only out
cut, but could bag leaves in the spring clean up way better than that damned
Huskvarna....again the Huskvarna had a larger Briggs engine by I think 3-5
HP more...so yup...my take is design and blades...........Jim
