John Deere 994R 60 Deck Ztrak

24.7 HP Diesel Commercial Zero Turn Mower

John Deere 994R 60 Deck Ztrak

The Z994R Diesel ZTrak Mower is equipped with a powerful and efficient Tier 4 compliant diesel engine that provides excellent performance, efficiency, and operator comfort without the cost and complexity of exhaust aftertreatment. Advantages over a comparable gasoline-powered machine include approximately 20 percent more torque to get work done faster, with 20 percent savings in fuel and overall cost of operation. 

 

The Z994R features a powerful diesel , liquid-cooled, horizontal-shaft diesel engine that delivers superior torque and fuel economy.

A dual element, canister-style air cleaner filters out dust and debris. A large, 11.5-U.S. gal. (43.5-L) fuel tank enables all-day mowing without refilling.
Unitized hydrostatic pump and wheel motor drives deliver performance, reliability, and easy operator use

 

 

The Z994R is powered by a three-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.
    • Engine wear reduced by ensuring proper lubrication, even when operating on hillsides or uneven terrain.
    • Oil filter helps keep oil clean for increased engine life.
  • Aluminum alloy pistons with built-in steel struts are lightweight to reduce connection rod bearing loads and provide good heat-transfer characteristics.
    • Design permits tighter tolerances and neutralizes expansion of the piston, thereby reducing blow-by fuel and noise from the piston slap.
    • Higher top rings on the piston and a thinner head gasket greatly reduce the volume of unburned waste and increase combustion efficiency.
  • Timing gears and injector drive gears utilize helical profile gears to help lower engine noise.
    • Gear teeth have a ''roll-off'' profile, giving almost no clash, no noise, and no backlash.
  • Glow plugs provide quick starts in temperatures down to -18°C (0°F)
  • Key start and shutoff eliminates fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.
