If you possess an Eclipse push mower, you have part of history. The Eclipse Lawn Mower Company, founded in 1900 by Fred Adams of Prophetstown, Illinois, stopped producing them in the early 1950s, when it started producing motorized versions, and the Eclipse Business was acquired by Hahn, Inc. in 1961. Eclipse push mowers usually have rubber tires and a rubber-coated roller. They also have two adjustments — one for adjusting for the length of the grass and one for setting the height of the cutting bar, which determines the way easily and effectively the blades cut.
Placing the Cutting Height
Locate the two lock nuts on each side of the roller, that’s the wooden dowel that tracks behind the cutting bar. They are on the inside of the frame that holds the roller and about 2 inches over the roller.
Turn both nuts using a wrench. If they are stuck and will not turn, douse them with lubricating spray, then permit the spray to work for a couple of minutes, and try again. Loosen the nuts sufficient to enable the roller to slide up and down to the frame.
Push down the elbow to lift the blade and cut the grass more evenly, and pull on the roller up to shorten the amount of the grass. Ensure both ends of the roller are the exact same distance from the top of the frame, then tighten the nuts.
Adjusting the Cutting Bar
Locate the two nuts on each side of the leading bar holding it to the lawn mower frame. Contrary to the nuts holding the roller, these nuts are on the outside of this frame. Loosen them using a wrench, using lubricating spray, if they’re stuck.
Notice the curved rod attached to the middle of the bar. It goes above the reel and connects to your tie rod on the front of the mower by means of adjustable wing nuts. There is one wing nut beneath the connection point and one over it.
Reduce the edge of the outer blade related to the reel by turning the lower nut counterclockwise and then turning the top nut counterclockwise by the exact same quantity. This pulls the rear of the cutting bar up and lowers the leading edge. Turn the nuts in the opposite direction to raise the edge of the cutting bar.
Use a bit of paper to find out the right setting for the bar. Put the paper between the bar and reel, have a helper push down on the handle to raise the mower wheels off the ground. Turn one of the wheels counterclockwise by hand. The bar is adjusted correctly if the blade slices the paper cleanly.
Tighten the nuts on each side of the bar when you are delighted with the adjustment.
