Walker delivers and excellent cut quality and the GHS is a good design but to all you walker users out there...... Can you tell me about the maintenance on them? I am thinking of getting one.. I've heard that they break down a lot and require a lot of repair and maintenance and that they arent very strong. Are there any machines I should consider? I would go for a Ferris Zero Turn or Toro and use the bagging system for the fall but.. I really like the out front deck of the walker that can mow more tight areas and cut down trimming time.. What do you guys think?
