i have a 36" toro WB. am trying to give it a spring cleaning before the season starts. i emptied the oil and tossed the filter. im gonna pick them up tomorrow. i also took apart as much as possible to clean of any old dust. once thats all done, ill put the new blades on and clean the under carraige. is there anything specific that i should be maintaining besides the oil and filter? im new to mowers and not knowledgable on maintenance. help me out anyone.
