Normal operation. Here is the function of the interlock module from the tech manual:
The interlock module performs the following functions:
Turn on the electric clutch if the operator is in the seat, the PTO/RIP switch is in the ON position, and the transmission is in forward or neutral.
Maintain power to the electric clutch if the operator is in the seat, and chooses to mow in reverse. By lifting the PTO/RIP switch to the Momentary ON position while shifting into reverse, the reverse override function is enabled, latching the power to the clutch.
Disables the reverse override when the operator shifts the transmission from reverse to forward or neutral.
Turn off and latch off the electric clutch if the PTO is on and the operator shifts into reverse without lifting the PTO/RIP switch. To reset the latch, the operator must place the PTO/RIP switch in the OFF position.
Turn off and latch off the electric clutch if the operator gets off the seat. A short time delay protects against bouncing. To reset the latch, the operator must place the PTO/RIP switch in the OFF position.
Turn off and latch off the electric clutch if the operator enables the brake switch.
