• 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

• Fast starts

• Smooth operation

• More horsepower and torque per cubic inch of displacement

• Better fuel efficiency

Air-cooled for minimum maintenance and maximum reliability

• Effectively dissipates heat to extend engine life

• Lightweight and strong construction

• 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

Standard cleanout ports for easy access to remove debris collecting in cooling fins

Oil Guard System delivers a 500-hour oil change interval

The Z965M, Z965R and Z985R ZTrak Mowers are equipped with the Oil Guard System which increases engine oil service intervals from 100 to 500 hours, which drastically reduces maintenance costs and downtime.

To further reduce maintenance hassles, engine oil-level checks, oil changes, and oil filter changes also move from the engine block to the accessible reservoir location. The reservoir has a large 5-quart capacity and aluminum construction for exceptional cooling and extended oil life.

ZTrak™ Z900 Mowers are equipped with a dual-element, canister-style air filter, easily accessible from the rear of the machine without tools.

• The filtration system pulls clean air from above the engine, in turn filtering out the dust that can damage an engine over time.

• Filters are extremely easy to change when required.

• Pre-cleaner provides more protection against contamination in dusty and dirty applications.
