Tomato Harvester Operational Safety

MASTER SWITCH- HARVEST MODE CONTROL 

Purpose: Engages all harvesting functions 

Does NOT engage: 

• Unloading conveyor
• Rear cross conveyor
• Suction fans (if shut off independently)

 Operation: 

• Move switch RIGHT → Starts conveyors
• Move switch LEFT → Stops conveyors
• Post-Emergency Reset Required: Set the switch to OFF before re-engaging harvest functions. 

EMERGENCY ENGINE SHUTDOWN (MAXIMUM STOPPING POWER) 

• Use ONLY in true emergencies – causes wear and potential engine damage. 
• To activate: Turn the ignition key switch (operator-side console) to OFF. 
• Result: Shuts down the engine to assist in stopping. 

OPERATOR- PRESENT SWITCH (SEAT SENSOR)

Location: Embedded in seat cushion. 

Function: Operator must be seated to activate ground drive & harvest functions 

If the operator leaves the seat: 

• 3 seconds → Warning chime sounds
• 7 seconds → Harvester
• Shuts down all harvest functions
• Comes to a complete stop (engine continues to run)

To Reactivate Functions: 

1. Sit in the seat to re-engage the seat switch 
2. Shift transmission to NEUTRAL
3. Throttle engine below 1200 RPM
4. Toggle master switch OFF → ON

EMERGENCY STOP SWITCHES 

Locations: 

• Left of the steering column
• Right side of the color sort conveyor
• Left side of the color sort conveyor

Activation: Push the red top-down → Stops all harvest functions and the harvester (engine continues to run) 

Reset Procedure: 

• Operator station: Twist the emergency stop (e-stop) knob → Automatically springs out to reset 
• Conveyor sides: Pull the red top out

Restart Procedure After Emergency Stop: 

1. Sit in the seat (activate the operator-present switch)
2. Shift transmission to NEUTRAL
3. Throttle engine below 1200 RPM
4. Toggle master switch OFF → ON

Rear Gate Sensors: The gates located on the rear left and rear right of the machine have an electrical switch which will de-active all harvest functions and ground drive if opened. The gates should only be opened when maintenance/service is required in the area. Utilize the rear left ladder to access the dipstick located behind the circular panel.

Operator Note: The all-harvest function will be disabled if the gate is opened; if the gate is opened during operation, the emergency stop procedure must be followed before reengaging the all-harvest switch.

IMPORTANT REMINDERS 

• Never use the engine shutdown method unless in a critical emergency. 
• Always throttle down and shift to neutral before restarting systems. 
• Regularly test emergency stop switches and seat sensors for functionality
