Engine Problems

• If your engine will not start, check the throttle lever position. Move it to the "Choke" position unless the engine is too warm. You may also be out of fuel. If your spark plug is faulty, or wet with fuel, this could cause the engine not to start. If your fuel filter is clogged, the carburetor or ignition are malfunctioning or the valves are stuck, you will need to replace these components. You may need to take it to a service center for these repairs if you do not know how to do them yourself.
  
  

Vibration Problems

• If you are experiencing excessive vibration, check the mower deck and blade for see if grass or debris are lodged in them. Your blade may also be loose, bent or damaged. If it is loose, tighten the blade bolts. If the blade is damaged, replace it. If you have mechanical damage, such as a bent crankshaft, you will need to replace it. You may want to have a professional do this.
  
  

Mowing and Bagging Problems

• If your mower is cutting poorly or not bagging correctly, check that the throttle lever is in the "Fast" position. You may also want to reduce the forward speed by shifting into the slow speed or you can push the mower slower. If the grass bag is overfilled or clogged, it could be causing your problem. In addition, check that all the cutting height adjustment levers are set correctly. Also ensure that the mower deck is not clogged.
