Replacing Dull Mowing Blades Replacing dull, dented mowing blades is an easy DIY project and it will help keep your lawn looking great and your mower running at it’s best. As you can see in the photo my 2 year old blades were in pretty rough shape. Part of this is due to our new lawn and all the rocks and debris I’ve hit . I could have sharpened these most likely and used them more but I wanted to have a spare set so I ordered a new pair. (Be sure to read my post about buying mulching blades for John Deere X300 ) Replacing mower blades is really quite simple. There are two methods of doing it. You can either completely take the mowing deck off the tractor or you can use a ramp to get enough clearance under the deck to work. I chose to use a ramp because I really didn’t want to take the time to completely remove the mowing deck. If you decide to use a ramp be sure it’s sturdy and you lock the parking brake on the tractor. Drive the tractor up onto the ramp so you have at least 6 to 8 inches of clearance under the mower deck. Now you’re ready to lay down on the ground and replace the mower blades. In order to remove the old blades and install the new blades you’ll need a wood block and a socket

wrench. Install the wood block on an angle between the old mower blade and the mower deck to keep the blade from turning when you remove the nut. Use the socket to remove the old nut and plate washer. Notice how the old blade is oriented so you can put the new ones back in the same orientation. Before you install the new blades its a really good time to remove old grass build-up from the bottom of the mower deck. A small flat putty knife works great for scraping off all the old build-up. You don’t have to get every last piece of grass out, just focus on all the large clumps of grass. Now just reverse the order and install the new blades. Each blade kit comes with new washers that you should use. Be sure to torque the nuts according to the manufacturers recommendations. Now you’re ready to get back to mowing. The new sharp blades will cut the grass clean without ripping and damaging the grass blades. This promotes healthy grass growth and helps prevent disease.
