I just looked at a Permagreen Magnum for 2008. They made a few changes. The motor mounts have spacers so now you can rinse underneath the motor to remove fertilizer residue--and moisture. Should reduce the chance of motor corrosion. And they added cushiony thick foam pads for the feet--should help to absorb some of those bumps and vibrations--good idea. They added very soft comfortable handgrips--not so different from the ones I have been using for years.
