A draft rod direct from the doubletrees to the cutter bar assists in lower- ing the draft, and is universally used on modern mowers. Adjustments of the Mower. The adjustments of the mower are of the greatest importance. First, the cutter bar should be in alignment, or should extend out to the side of the mower at right angles to the crank shaft. If not in per- fect alignment, the pitman will be cramped, increasing the wear, if not causing early breakage. There is sure to be more or less wear in the hinge joints of the cutter bar, and. Fig. 164. An illustration showing- the proper adjustment of the cutter bar. an adjustment must be made for this wear from time to time. The device for aligning the cutter bar differs in each type of mower, yet it is to be found in all good mowers. Secondly, the knife should be made to register, or to travel equally over the guards at the ends of the stroke. Misadjust- ment in this respect is often the cause of failure to cut proper- ly. The method of adjustment varies with different mowers. In some the length of the pitman is changed; in others, the length of the drag bar. It is also true that many mowers do not offer a ready means of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Davidson, Jay Brownlee, 1880-1957.
