The interlock modules function is to prevent the engine form starting if the blade and/or ground speed lever are engaged. It also causes engine shutdown if the operator falls from, or attempts to leave the operator position while the blades or ground speed lever are engaged. After the engine starts, the operator must hold either the left or right O.P. lever down before engaging the blades or moving the ground speed lever. If neither O.P. lever is held the engine will stop. Check the function of the safety electrical system on a regular basis.

1.Engine must kill if blades are engaged without at least one O.P. lever held down.

2.Engine must kill if ground speed lever is taken out of neutral without holding down at least one O.P. lever.

3.Engine must not start unless blades are off and ground speed lever is in the neutral position.

4.Do not operate the mower if the interlock safety system allows operation or starting in any unsafe condition.
