I own one
I had mine for 2 years.It is the best thing that ever happened to aeration.not best for small lots ,and isn't worth it for small islands in middle of parking lots.
I have mine attached to a 52" stander,I can hook it to the 48" but the 52" has wider tires.It is ZERO maintenance,no belts,oil,filters adjustments,nothing.
two of my customers saw me use it and loved it.the gap in between the two front casters isn't a problem at all,just cross pattern.
it is the manual model to raise up and down,But I removed the handle and installed a socket,now I raise and lower it with my cordless impact wrench,much faster,I always have a spare battery.
the more you raise the front tires,the bigger the plugs.
I got to a 1/2 acre property once and a guy was doing the next door neighbor.
We cut the grass,aerated and overseeded,no sweat,finished and left while the other guy is still raising and lowering his walk behind model.
Don't understand me wrong,walk behind model is still good( i got one)but the zrator out performs it.
