Wing Nut Plastic 1/4-20 Thd. 712-3087

Needed a mulch plug to cut up fall leaves. This is a circa 1999 MTD yard machine tractor. I have long since removed the actual chute so the thrown cuttings would spread rather than pile. The mulch plug fits into the slot nicely but the bolt hole in the plug doesn\'t line up with anything on the deck to put the bold through. So I put the p ... Read more lug in and used a small C clamp to locate where I needed to drill through the deck. put the short end of the clamp over the hole and tightened down the clamp to the top of the deck. Not too tight because the clamp begins to slip on the plastic mulch plug because it doesn\'t mount perfectly flush to the bottom of the deck so just tightened it down just short of it shifting off of the hole. Then I scratched the deck on four sides of the clamp on the top of the deck. Removed the clamp and found \"about the center of the scratch marks.\" Doesn\'t need to be absolutely exact because the mulch plug has a little give. Used a center punch to create a little dimple so the drill wouldn\'t slip. Drilled the hole, it lined up pretty good and secured with bolt, washer and thumb screw nut. I added a lock washer because things like this always tend to vibrate loose. Works great but the thumb screw loosened a bit so might use a regular nut so I can tighten down more. Made my life a lot easier because it works great and no longer have to keep going back and forth cutting the leaves smaller with each pass and not ending up with a big pile of mulch in rows. If you can use a drill, simple installation.
