Powerful 30.5 hp (22.7 kW) engine has electronic fuel injection (EFI) and electronic throttle control for quick starts and superior performanceA commercial-quality, 30.5 hp (22.7 kW) gross at 3600 rpm, air-cooled engine with EFI powers the Z955M and Z955R ZTrak™ Mowers.
Engine features include:
EFI with electronic throttle control- Electronically adjusts the supply of both fuel and air, responding instantaneously when the mower transitions from light to heavy mowing.
- Unlike mechanical governors that droop under load, torque rises while maintaining constant full-throttle engine speed.
- Productivity and cut quality are improved because the mower blades keep turning at full speed, delivering optimal cut quality and dispersion of clippings.
- Immediate starting in hot or cold ambient temperatures or after long periods of seasonal storage
- No choke linkage for the user to operate
- Higher reliability with the elimination of vapor locking, misfiring, run-on, and after-bang
- Automatic altitude compensation
- Delivers fuel precisely for added efficiency
- Reduces the potential for plug fouling
V-twin designOverhead valves- More horsepower and torque per cubic inch of displacement
Air-cooled for minimum maintenance and maximum reliability
Aluminum cylinder block- Effectively dissipates heat to extend engine life
- Lightweight and strong construction
Full-pressure lubrication with full-flow filter- Reduces engine wear by ensuring proper lubrication, even when operating on hillsides or uneven terrain
- Filtered oil reduces risk of contamination for increased engine life for increased engine life
- Oil cooler helps keep engine at optimum temperature
Standard cleanout ports for easy access to remove debris collecting in cooling fins
30-amp alternatorComplies with strict Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emission standards without loss of horsepower or torque.
