I have a Toro Super Recycler I use as a trim mower and for smaller yards. Lately I have been having to bag grass because the mower is not mulching well and leaving a trail of cut grass behind on the driest of days in August. I have checked and done a lot of things - spark plugs checked and looked OK, new air filter, sharp blades, clean deck. None of this seems to have helped. I have a governor spring on order which may help if the old one has lost tension. Is there anything else I can try?
