  • Cup Holder and Storage Space: Keep beverages and tools close at hand with the storage box and cup holder located next to the seat.
  • Get Jobs Done Faster: With a top speed of 11.2 mph – the highest speed in its class – the Z700 Series ensures superior productivity.
  • Easy Maintenance: Battery and harness parts can be accessed just by raising the seat panel; fuel shutoff and fuses are also located under the seat. Equipped with dual Parker® transmissions; designed for easy maintenance, each transmission has an integrated pump and motor for increased efficiency and simplified service (*Parker® is a registered trademark of Parker Hannifin Corporation)
