Light emitting diode (LED) headlights complement modern styling

The 100 Series Lawn Tractors are equipped with LED headlights that:

• Complement the tractor’s modern styling
• Use less power and are far more durable than incandescent light bulbs
• Provide a natural light quality that increases visibility in low-light conditions
• Light the field of view evenly

Hood will not rust or dent

The hood used on 100 Series Lawn Tractors is made using the mold-in color process. The hood reduces sound, will not rust or dent, and provides resistance to UV light. Side openings let in plenty of cooling air while keeping the sound level low.

Reliable full-length welded steel frame

1. Stop forward travel.
2. Look behind the machine to be sure there are no bystanders.
3. Push and hold in the RIO switch while depressing the reverse pedal slightly for a hydrostatic transmission or moving the transmission shift lever to the rear slot (reverse) for a continuously variable transmission (CVT)/automatic transmission.

NOTE: If the engine and mower or other attachment stops while repositioning the machine, return the attachment engagement lever/switch to the off position. Start the engine and engage mower or other attachment. Begin again with step 2.

4. Release the RIO switch and reposition the machine as the machine begins to move rearward.
5. Resume forward travel. The mower or other attachment should continue operating.
6. Repeat procedure to position the machine again.
