between a 48" Quest X and a 48" Radius E. About the same price. Same transmissions, different engines, Kohler on Quest vs Exmark on the Radius. Looks like the PTO may be better? Radius is bigger with a stronger frame but also weighs a couple hundred pounds more. Is bigger/heavier always better? Soft/wet lawn? Does the better PTO allow use of different accessories? Is the Exmark motor reliable and good or is the Kohler better? The Radius is $70 less expensive but available at a dealer 30 miles from home. Quest from my local dealer I've worked with for years and they can't get a Radius E. Thoughts/Suggestions?
