Push mowers are environmentally friendly and have come a long way in the years since portable gas mowers overtook the marketplace. These mowers now boast a more lightweight assembly and improved maneuverability. Although usually requiring more than one pass over a yard to properly trim the grass, many prefer the quiet appeal of bar mowers over their nosier and smellier counterparts. You can easily adjust push mowers to accommodate a cutting height range from 1/2 to 3 inches with a quick adjustment of the roller assembly.
Things You'll Need
Locate and remove the nuts on either side of the roller assembly.
Move the bolts into the holes beneath the current setting on the plastic roller bracket if you wish to lower the cutting position. If you want to leave the grass longer, adjust the blades into a higher position on the bracket. Be sure to keep both sides equal when making the adjustment.
Re-tighten both of the nuts on the roller assembly.
Correct misalignment in the blades (either too tight or too loose) by adjusting the screws at the rear of the mower located on the bar blade beneath the reel pivots. The rear screws move the cutter blades forward towards the reel bar while the front ones move the blades away from the bar.
Tighten only in 1/16 inch increments as the screw adjustment mechanism is very sensitive. When adjusting or tightening one set of screws, be sure to loosen the opposing screws an equal amount.
Loosen both rear screws equally to allow more give in the blades by turning them in a counterclockwise motion; then tighten both of the front screws an equal amount by moving them clockwise. Tighten the blades by loosening both front screws equally in a counterclockwise motion and tightening the rear screws the same distance clockwise.
Tips & Warnings
- Check your blade adjustment by turning over the mower and inserting a piece of paper between the blades of the reel and the cutter bar, moving the blades by hand to make sure it slices evenly over the length of the cutter bar.
- Apply WD-40 regularly to all cutting surfaces, shaft and wheels to keep things working smoothly.
