FEATURES
Powerful 24.7-hp (18.4-kW) diesel engine delivers superior performance and efficiency
The Z994R is powered by a 3-cylinder, liquid-cooled diesel engine with gross SAE J1995, PS 24.7 hp (18.4 kW) rated power at 3200 rpm that meets U.S. Environmental Protection Agency (EPA) Final Tier 4 emission standards:
High-torque, low-emission diesel engine for strong performance in the toughest conditions
Low vibration and noise levels
Isolated with rubber mounts for a smoother operator ride
Superior fuel economy
High torque reserve for plenty of power and performance
Key features of the engine include:
Economical, cast-in block cylinder design provides good cooling and long life.
Liquid-cooled design provides more consistent operating temperatures than air-cooled.
Fuel filter with replaceable element is provided.
Indirect fuel injection uses a pre-combustion chamber to give the engine smooth and quiet operation.
Full-pressure lubrication with full-flow filter lengthens engine life.
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.
Glow plugs provide quick starts in temperatures down to -18°C
Key start and shutoff eliminate fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.
Dual-element, dry-type air cleaner with safety element and air service indicator
Dual-element design for added engine protection and easy service
Completely sealed for effective cleaning
Ninety to 95 percent of dirt ejected before it reaches the paper element
Air cleaner restriction indicator to let operator know when the filter needs servicing
An automotive-type radiator, coolant reservoir, and electric cooling fan are provided to remove heat from the engine coolant:
The cooling fan is thermostatically controlled so it only runs when necessary.
See-through coolant recovery tank permits the operator to check the coolant level without removing the radiator cap.
The Z994R Diesel ZTrak™ Mower is equipped with a single 43.5-L fuel tank that provides enough capacity to allow mowing for a full day without refueling:
Large, angled filler neck makes for easier refueling
Fuel cap tether is provided to secure the filler cap while refueling
Fuel gauge is provided as standard equipment
Four 7-Iron™ PRO Side-Discharge Mower Deck options give superior performance in every application
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.
Strength of cast iron protects against damage from blade impacts.
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.
Features include:
Higher blade tip speed of 18,000 fpm (5486 m/min) gives more blade strikes per distance of forward travel.
The front baffle is designed to better manage airflow and control clippings.
Spindle-pocket reinforcement provides even greater structural durability.
A raised discharge chute allows for even clipping distribution.
Thick, 7-gauge, 0.179-in. (4.55-mm) steel construction gives commercial durability.
The three-spindle design provides a smooth, even cut.
A plastic discharge deflector reduces damage to foliage and resists bending.
The formed, steel-deck design is stamped from a single sheet of steel to eliminate corners where grass can collect.
The deep deck gives increased vacuum action that reduces dropped clippings.
Belt drive efficiently transfers power from gearbox to spindles.
Spindle grease fittings are on top for easy access.
Quick-change cutting-height adjustment is easy to use.
Blade overlap of 1.57 in. (40 mm) reduces the number of missed grass blades.
A mulching attachment is available.
The Power Flow™ rear material collection system is available.
Quick release belt covers for added convenience
Exceptional operator comfort begins with a high-quality seat and suspension
Large, open operator station and foot platform with plenty of legroom and room for multiple foot positions
Instruments, controls, and storage areas that are easy to see and use
Three-position rollover protective structure (ROPS) and retractable seat belt for operator safety and convenience
