•THROTTLE/CHOKE CABLE ADJUSTMENT: Correct throttle cable adjustment allows for full range of motion on engine throttle body in conjunction with throttle control on handle dash. Correct choke cable adjustment engages choke when choke knob is pulled fully out. To adjust either cable, loosen cable clip screw on engine, then slide cable in or out. Retighten screw, recheck, readjust as needed.

•SAFETY SWITCH ROD ADJUSTMENT: Loosen set screws on safety handles, raise each handle approximately 1/4 – 1/2”, retighten one set screw, check for uniform contact between both handles with handle assembly, retighten other set screw. Note: tighten set screws to 150 in. lbs.

•STEERING ADJUSTMENT: Check tire pressure – 20psi rear, 50psi front. If correct, see Brake adjustment.

•CUTTING BLADE HEIGHT ADJUSTMENT: Each blade assembly contains six 1/4” blade spacers: three on the bottom of the spindle assembly between blade and spindle, and three above between the spindle and the blade bolt jam nut. Combined with the axle adjustment set at the factory, cutting height is set at approximately 2-1/2”. Cutting blade height can be adjusted to between 1-3/4” and 3-1/4” by removing jam nut and repositioning washers. Retighten jam nut to 60 ft. lbs.

•AXLE HEIGHT ADJUSTMENT: Your unit comes with a unique rapid-adjust axle assembly for additional cutting height adjustment. Initial factory adjustment sets the bottom rear edge of the blade deck approximately 1-1/2” above the mowing surface; however, it can be adjusted to 5” in height. To adjust, first position a jack under the rear of engine deck and raise. Loosen the two 3/8” bolts on either side of axle assembly (held in place by press-fit nuts, so only one wrench is needed). Drop or raise axle assembly to provide desired height, then retighten bolts. Remove jack and adjust the front casters by repositioning the spacers. Note: Remember that factory-set cutting blade height is 1” above bottom edge of blade deck. Note: It is recommended that the front height of the mower be adjusted to 1/4” lower than the rear, to allow for the blades to cut with the leading edge and thus assure a finer cut.
