Push reel mowers are easily adjusted. New push reel mowers are adjusted before shipping to the store. Minor adjustments must be made over time as the blades become too loose or too tight. When your mower becomes too hard to push or you notice an uneven cut it is time to adjust the blades. Adjustments are made behind the mower (from an operating position, the rear is closest to the operator). The ends can be adjusted separately
Turn the rear screws counterclockwise (to the left) to loosen them. Turn the front screws clockwise (to the right) to move the cutter bar away from the blades. Turn all the screws equally (if turning 1/32 inch on one screw, all four must be turned 1/32 inch). Do not turn more than 1/16 inch. This will loosen the cutter bar so that it does not hit the blades, stopping the mower from moving.
Turn the front screws counterclockwise to loosen them. Turn the rear screws clockwise to tighten them. This will move the cutter bar closer to the blades. All screws must be turned equally.
Turn the push reel mower upside down. Place a long strip of newspaper between the reel and the cutter bar. Turn the reel manually to ensure that the blades are cutting evenly. Make further adjustments as necessary.
