Page 8 I. SAFETY/DECALS OPERATING TREAD WIDTH  Select the widest tread setting to fit between the crop rows.  Never manually adjust the tread width on the detasseler until the wheels have been properly blocked. Loosen the leg clamp bolts only enough for the leg to slide on the frame. OUTRIGGERS ...
Page 9 I. SAFETY/DECALS REPAIR/MAINTENANCE HYDRAULICS  Use caution when working with hydraulic fluid under pressure. Escaping hydraulic fluid can have sufficient force to penetrate your skin, causing serious injury. This fluid may also be hot enough to burn.  Always lower load or relieve hydraulic pressure before repairing a hydraulic oil leak. ...

Page 26: Preparing To Operate
IV. PREPARING TO OPERATE WHEEL TREAD AND ROW SPACING Knowing the row spacing of the field one intends to detassel, follow the steps below to properly obtain the desired tread 1. To adjust the tread width in or out, park the detasseler on level ground and shut off the engine.
Page 27 IV. PREPARING TO OPERATE TREAD WIDTH CONTINUED 3. Loosen the leg mounting bolts on both the front and rear legs on one side of the detasseler only (fig. 4.3). Loosen leg mounting bolts only enough to allow for free movement of leg on mainframe. DO NOT remove bolts under any condition.
Page 28 IV. PREPARING TO OPERATE TREAD WIDTH CONTINUED 8. To adjust the tread out, place a suitable prying tool under the center of the tire and pry out at the same time that you push out at the top of the leg (fig. 4.6). Carefully lower the detasseler to the ground which, in turn will allow the leg to slide outward.
