The Scotts Reel Mower makes adjusting the cutting height easy. With its simple height adjustment lever, you won't normally need to disassemble the mower to adjust it. With any reel mower, you should mow more often than you would with a traditional mower. If it has been awhile since you last cut your grass, you will need to adjust the mower higher. If you are mowing shorter grass, you'll need to lower the height adjustment. Determine your height needs before adjusting.
Depress the height lever located on each side of the mower. Move the lever higher or lower to the preferred height. Factory settings place the height adjustment between 2 and 3 inches.
Let go of the lever on each side to allow it to spring into place.
Check that the height on each side matches the other.
Remove the hub cap from the wheel if you want to place the cutting height below 2 inches. Insert a screwdriver in the slot on the cap and loosen the wheel until it pops off.
Hold the axle pin steady with a screwdriver. Use a box-end wrench to remove the nut.
Pull the wheel, dust cover and axle forward until the axle's end clears the mower's side. Move the axle to one of the two open spots. Reassemble and tighten the axle nut.
