If you mow your lawn frequently or have had the same mower for a number of years, it might be time to replace your grass bagger, otherwise known as a grass catcher. Depending on the kind of mower you have, this could be costly, but if you don't mind taking the time, there are some simple steps you can follow to design your own at home. Ideally, these designs work best for push mowers, but consult a lawn care technician to find out if an altered version might work for your riding mower.
Assemble your materials and make sure the lawnmower is turned off before beginning the process.
Attach your bag to the discharge area by wrapping the bag around the chute at the back of the mower where the grass comes out, and duct-taping it in place. Make sure it's secure so no grass clippings escape. This also ensures easy removal at the end of your mowing session.
Take the other end of the trash bag and wrap it around the support bar at the back of the mower and duct tape it in place. If you find this awkward or you think it makes the bag too taut, poke a tiny hole through the end and use a twist tie to secure the bag to the bar. You're ready to begin mowing.
Remove the bag after mowing by releasing the end attached to the support bar first, to keep all the clippings from falling out of the bag. Lower that end to the ground, then remove the end attached to the discharge chute.
Dispose of the clippings and reattach the bag, or dispose of it and set the materials aside to make a new bagger the next time you mow the grass.
This method works best for mowers that discharge clippings out the back. For mowers that discharge clippings on the side, or for riding mowers, consult a lawn care technician before clipping to make sure it's a safe option for you.
