I have a Walker with a 42' GHS deck and a 42" mulching deck. My problem is changing the decks during the course of the day is a pain. I have some mulching and some collection accounts. I want to add a 48" or larger walk behind or small rider for side discharge and use the Walker GHS. I want the most for the least (don't we all) in the walk behind or rider. I need to make this addition soon. Suggestions as to brand, size or other options will be greatly appreciated.
