Having problems with stragglers with my metro. I'm mulching with 2 spacers above and below on both the casters and blades. I tightens the belt and sharpened the blades with no improvements. Also, thanks for the transmission post. My metro locked into 4th. on Monday. Thoughts of a new tranny went through my head until I took the tranny apart w/o removing it and fixed it. Lube problem.
