John Deere 100 series mowers are available with engines of different horsepower and accessories that allow them to be used in a wide range of applications around the home. You can do much of the maintenance associated with the 100 series at home, including replacement of rear tires. Replacing a tire may be the result of normal use or damage from a nail or other sharp object and requires only a few basic steps.
Park the John Deere 100 series mower on a solid level surface such as a driveway or floor of a workshop. Set the parking brake to help prevent the mower from rolling.
Place a floor jack or automotive jack under the transmission. Locate the transmission in the center of the mower between the rear wheels. Raise the back of the mower off the ground and place a jack stand near both rear wheels at the point where the frame mounting bolts come through. Lower the jack and rest the mower on the jack stands.
Place wood, concrete, or brick blocks against the front wheels to keep the mower from rolling. Put on gloves to protect your hands while working.
Remove the plastic cap in the center of the wheel and tire that you wish to change. Twist and pull the cap to remove it.
Place the tip of a screwdriver under one end of the C-clip. Gently pry the end up and pull it off the axle. Use a pair of pliers if necessary. Pull the washer behind the C-clip off the axle. Keep both the snap ring and washer for re-installation.
Pull the wheel and tire off the mower. Slide a replacement wheel and tire on the axle followed by the washer and snap ring. Place the C-clip on the axle indentation and push down on the center to snap it into place. Place the plastic cap back on the axle by pushing it in place.
Raise the jack to support the mower and remove the jack stands. Slowly lower the mower to the ground and remove the blocks at the front of the mower.
