FEATURES:
Powerful diesel engine for increased performance
Key features of the engine include:
Economical, cast-in block cylinder design gives good cooling and long life.
Liquid-cooled design provides more consistent operating temperatures than air-cooled.
Direct fuel injection is provided.
Aluminum alloy pistons with built-in steel struts are lightweight to reduce connection rod bearing loads and provide good heat-transfer characteristics.
Timing gears and injector drive gears utilize helical profile gears to help lower engine noise.
Fuel filter with replaceable element is provided.
Auto-bleed fuel system gives extra convenience.
Key start and shutoff eliminate fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.
See-through coolant recovery tank permits operator to check coolant level without removing radiator cap.
Sealed radiator compartment keeps trash and debris on outside of hood.
Dual-element, dry-type air cleaner with safety element and air service indicator is provided.
Full-pressure lubrication with full-flow filter lengthens engine life.
Automotive-type alternator (75 amp) provides plenty of charge to the battery.
Rear-mounted, covered radiator and fan keeps noise away from the operator and is easy to service.
Isolated engine mounting reduces engine vibration at operator’s station for more comfortable operation.
The ZTrak™ Z997R Diesel Mower is equipped with a dual-element, canister-style air filter that is easily accessible from the rear of the machine without tools.
Filtration system pulls clean air from above the engine, in turn filtering out the dust that can damage an engine over time.
Filters are easy to change when required.
Pre-cleaner provides extra protection against contamination in dusty and dirty applications.
The Z997R Diesel ZTrak™ Mower is equipped with a single fuel tank, providing the following:
45.4-L capacity allows the operator to mow for a full day without refueling.
Large filler neck makes for easier refueling.
Standard fuel gauge is provided.
Top fuel draw provides added safety by reducing the chance fuel will leak out.

Two 7-Iron™ PRO Side-Discharge Mower Deck options for the Z997R give superior performance in every application
There are two side-discharge mower-deck options available for the Z997R Diesel ZTrak Mower:
The 72-in. (183-cm) 7-Iron PRO side-discharge deck is suited to a variety of mowing jobs, including trimming and grooming on larger properties
On every commercial mower deck there are three 1-in. (25-mm) spindles that are cold-forged and heat-treated for strength. Spindles are supported by precision ball bearings that provide great performance and reliability.
Superior impact strength provided by ductile cast-iron material.
Gusseted design puts reinforcement where it is needed.
Easy access grease fittings are mounted at the top of the spindle shafts for convenience.
Grease pressure-relief valve minimizes seal damage from overfilling with grease and keeps debris from entering housing.
Chance of deck shell damage is minimized with the 8-in. (20.3-cm) diameter housing and six mounting bolts that distribute loads and impacts.
Ability to be reliably rebuilt is provided by use of cast iron.
Mower decks are shaft driven. Benefits of using this type of system include:
Live independent power take-off (PTO) powers the mower deck.
PTO can be engaged or disengaged on the go for greater productivity.
Hydraulic PTO clutch has delay relief valve for soft engagement.
Wet clutch is designed for long life.
PTO is easily accessible.
250-lb-ft (339-Nm), heavy-duty hydraulic clutch provides long life.
Splined PTO shaft transfers power to the cast-iron gearbox.
Features include:
Higher blade tip speed – 18,000 fpm (5486 m/min) gives more blade strikes per distance of forward travel.
Front baffle is designed to better manage airflow and control clippings.
Ductile cast-iron blade-spindle housings have a gusseted design for extra reinforcement.
Spindle-pocket reinforcement for even greater structural durability.
A raised discharge chute provides even clipping distribution.
7-gauge, 0.179-in. (4.5-mm) steel construction gives commercial durability.
3-spindle design provides a smooth, even cut.
Plastic discharge deflector reduces damage to foliage and resists bending.
Formed, steel-deck design is stamped from a single sheet of steel to eliminate corners where grass can collect.
Deep deck gives increased vacuum action that reduces dropped clippings.
Shaft drive from engine to mower gives excellent reliability.
Belt drive efficiently transfers power from gearbox to spindles.
Grease fittings are greased from the top for easy access.
Quick-change cutting-height adjustment is easy to use.
Tricycler mulching kits are available.
Blade overlap of 1.57 in. (40 mm), nearly 0.79 in. (20 mm) greater than previous decks, reduces the number of missed grass blades.
Minimal service requirements increase uptime:
Quick-release belt covers do not require tools or the removal of a ring clip; just lift one corner of the cover and rotate it slightly to remove.
Convenient spindle greasing with fittings at the top of spindle shafts are accessible through a hole in the top of the spindle/belt covers.
There is only one belt to service.
Standard operator comfort and convenience package for ease of use
The Z997R Diesel ZTrak™ Mower is ergonomically designed to give the operator an enjoyable and comfortable ride while increasing productivity.
