HOW TO USE YOUR LAWN MOWER

ENGINE SPEED CONTROL

MODELS WITH REMOTE THROTTLE
Engine speed is controlled by the throttle control located on the upper handle.

  • Move lever forward to FAST engine speed for starting and better bagging.
  • Move lever backward for SLOW engine speed.
  • Some models have engines equipped with a choke feature. Move the lever all the way forward to the CHOKE position when starting a cold engine.

MODELS WITH FIXED SPEED ENGINES
Engine speed was set at the factory for optimum performance. Engine speed is not adjustable.

TO ADJUST CUTTING HEIGHT

ALL MODELS
Adjust cutting height to suit your requirements. Medium position is best for most lawns. Raise wheels for low cut and lower wheels for high cut.

"MANUAL" ADJUSTMENT

  • Remove wheel, bolt, and hardware and reassemble in desired adjustment hole.
  • Reinstall wheel components in the same order as they were before removal.
  • Tighten securely.
  • Make sure all wheels are at same height.

"QUICK" ADJUSTMENT

  • To change cutting height, squeeze adjuster lever toward wheel. Move wheel up or down to suit your requirements. Be sure all wheels are in the same setting.

"QUICK-PIN" ADJUSTMENT

  • To change cutting height, pull up on adjuster lever, move wheel up or down to suit your requirements and release adjuster lever. Be sure all wheels are in the same setting.

"DUAL POINT" ADJUSTMENT
Both front wheels are adjusted by a single lever on the left front wheel. Likewise, both rear wheels are adjusted by a single lever on the left rear wheel.

  • Pull adjuster lever toward wheel. To raise mower, move lever forward to desired position. To lower mower, move the lever toward the rear.
  • Be sure to adjust both front and rear wheels to the same height.

"SINGLE POINT" ADJUSTMENT
Pull adjuster lever toward wheel. To raise mower, move lever forward to desired position. To lower mower, move the lever toward the rear.

"THREE POINT" ADJUSTMENT (18" (45cm) HI-VAC MODELS ONLY)
Both rear wheels are adjusted by a single lever on the left rear wheel.

  • Pull adjuster lever toward wheel. To raise mower, move lever forward to desired position. To lower mower, move the lever toward the rear.

CASTER WHEEL OPERATION ("THREE POINT" ADJUSTMENT ONLY)
The front wheels can be "locked" into position or set to "freewheel" for better maneuverability.

TO CONVERT MOWER:

"REAR DISCHARGE ONLY" MOWERS
Some models have a seperate mulcher plug, other models have the mulcher plug built into the rear door. To convert to bagging or discharging, the plate or plug (if so equipped) must be removed from the discharge opening of the lawn mower.
