Powerful turbocharged diesel engine for superior performance
The 1600 Turbo TerrainCut WAM is powered by a liquid-cooled, turbocharged, four-cylinder, 60-hp (44.7-kW) at 3000 rpm, PS diesel engine.
Engine features include:
117.3 lb-ft (159 Nm) of torque at 3000 rpm for extra lugging power on hills and in tough mowing conditions
Large 127.6-cu in. (2.091-L) displacement, which produces the torque needed to handle hills and tough mowing conditions
Engine is a 16-valve (four valves per cylinder, two intake and two exhaust) design:
Cold-start device to increase engine timing for improved cold starting
Full-pressure lubrication for positive lubrication with continuous operation on slopes
Dual-element air filter that is completely sealed for effective cleaning
Progressive-type air-restriction indicator to let operator know when the filter needs servicing
Automotive-type alternator (75 amp) that provides plenty of charge to the battery
Glow plugs for quick starting in cold weather
Automotive sensing system, which tells the operator when the engine is ready to start
Isolated engine mounting, which reduces engine vibration in the operator's station for more comfortable operation
Direct fuel injection
Injects fuel directly on top of pistons for more efficient combustion, less emissions
Delivers more power per gallon of fuel
Quicker starting and quieter operation
Designed to meet California emission standards
Features low levels of exhaust and emissions and excellent fuel economy. It meets the necessary Environmental Protection Agency (EPA) Tier 4 standard and meets 97/68/EC EU non-road mobile machinery (NRMM) emissions regulation
Electronic engine control and cooled exhaust gas recirculation (EGR) system
High-pressure common fuel rail for lower emissions and improved engine responsiveness
Flow of exhaust during engine operation
Exhaust airflow enters into the EGR cooler from the exhaust manifold near the turbocharger
Cooler takes hot exhaust gases and cools them to where the temperature will not have excessive impact on combustion efficiency
Based on load, air temperatures, and rpm, the engine control unit (ECU) opens (or closes) the EGR valve, allowing exhaust gases into the intake manifold. The gases mix with the rest of the incoming air from the turbocharger and aftercooler.
Other engine features:
Overhead valve (OHV) for efficient combustion
Liquid-cooled for more consistent operating temperatures
Closed crankcase ventilation that burns crankcase hydro-carbon evaporation
Deluxe air-intake system
Hood that is composed of a large, black, cross-link polyethylene-composite center section with green, metal side panels
The composite center section includes air-intake screens and helps to guide the cooler air from above the machine to the radiator. The design provides a uniform distribution of clean air, as well as minimizing the amount of chaff collection on the exterior screens.
Additional sealing around the operator station reduces the amount of hot air blowing on the operator, which in turn improves operator comfort.
The rear bumper helps with hood sealing and reduces the potential for rear hood damage.
