I'm still in the zero turn mower market and still considering the cub cadet m60 tank commercial mower with the 29hp liquid cooled engine. Although these mowers are not known for their stability on sloped ground, even with the extra aggressive tires on this particular mower it still slips & slides! /forums/images/graemlins/shocked.gif Has anyone tried filling these tires or adding more weight? If so, Does it make the front too light for going uphill? What are some suggestions?? Should I consider a different mower all together?? Thanks!! /forums/images/graemlins/grin.gif
