Rickk , what you have been experiencing is is a time space continume .....the mower is obviusly IN motion right ....?
the yard loses part of it's mass as you move . covering distance to reduce mass , so the faster you go the less time and more mass is reduced in a shorter period of time .
stick with me now .........if we subsatute beer for "speed of light" or C in the equation . e=m c squared
we find that while the distance is the same and the time is the same ,the illution of time passes quickly while riding your relative insterment , and sipping on time preception alteraqration fuel.
That the yard actualy shrinks in size in a pulsing manner . the mower gets more powerfull , and you are done sooner because of the beer ........ and the smaller yard and the more powerfull mower .
if you float your 'boat(mower)' on empy beer cans and it sinkkkkkssss . well you may find yourself
riding that mower up the greasy grass at the battle of Little Bighorn .....at exactly the time and year you would LEAST enjoy . get the point ?
there's an outside chance that you will be invisable if you had consumed enough time spinner.
or in jail nowadays .........these things are still mystries .
eta you mayhave been the one they were counting on to tow their gattling guns to ol george in time .
or CANNONS .
