2025 John Deere 1600 Turbo TerrainCut™ 128 in

Turbocharged diesel engine

Rear-discharge decks

FT4 engine compliant

Features may include:

• 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.
