Why oh why do the manufactures of walkbehinds put the blade engage lever on the left side. Everyday I have pine trees disengage my blades. 95% of the time when going around objects (much beds, posts, trees, etc...) I travel with chute facing out. Inevitably thick branches will catch my lever and disengage. Why can't they put this lever on the right side? maybe some do. Thanks just a thought.
