I have a 3-4 year old Sutech Stealth with a 10.5hp engine. It has 3 small blades, 12" each. I noticed the back is shaped to the blades but the front of the deck is not so the grass clumps there. Is there a baffle available for it? Is there any easy way to make a baffle or something for it to keep the grass from moving to the front. Thanks.
