Reel mowers may be a more practical mower for homeowners with small yards or for someone trying to be more "green." Reel mowers are manual push mowers that cut the grass by using a scissors type cut instead of a ripping cut, such as gas mowers. This gives your lawn a more polished look. Just like a gas mower, you can move the blades on the reel mower up or down depending on how tall you want your grass. For the average homeowner, it is usually recommended to keep your grass slightly taller in the summer to help prevent burnout. Between 2 to 3 inches is a good length.
Remove one wheel by popping off the end cap. Use a flat-head screwdriver to remove the metal ring holding the wheel in place.
Use a socket wrench to loosen the nut holding the mower in its current setting. You may need a wrench to hold the bolt. This will keep it from spinning while you loosen the nut. Remove this bolt completely.
Adjust your mower height either up or down and replace the bolt. Use the socket wrench again to make sure it is tight.
Place the wheel back on. You may need to use a needle-nose pliers to get the metal ring back on.
Repeat these steps on the other side so your reel mower is balanced.
