That's really good.
I want to design and build in my shop a 4 wheeled, steerable pedalpower 
machine that
lightly tills/scarifies/breaks-the-crust of the surface of large wide tall
raised garden beds dragging an adjustable tillage tool underneath the chassis 
down the beds;
this could also be capable of removing emerging weed seedlings with a change 
of tillage tool teeth. This could also be a
walk-behind machine that you push and steer and can lift to keep the tillage tool level with bed surface when 
encountering discrepancies between bed height and furrows the machine's wheels ride in. I think this can be accomplished 
with the use of a hydraulic/shock absorber suspension enabling you to tilt the machine in either of four directions, 
forward or backward or side to side to keep the tiller level with bed surface. These types of shocks are used in 
openable hatchback or rear windows on cars or trucks (the window in a camper over the tailgate on a truck). The pistons 
on these shocks have full movement with resistance and stay put in position fairly well when window is raised; this 
would be perfect for a garden tiller stabilizer/adjustable suspension. Anyone know what these kind of shock absorbers 
are called?
