2025 John Deere 1580 TerrainCut™ 62 in. Fastback™ rear discharge

7-Iron™ PRO Side Discharge or FASTBACK™ Rear Discharge Deck

Diesel Engine

Compatible with select front blade, snow blower and broom attachments

Features may include:

• Diesel engine has high-quality features to minimize operating cost

• The 1500 Series TerrainCut™ Front Mowers are powered by liquid-cooled, 3-cylinder diesel engines.

• These engines feature low levels of exhaust and emissions, reduced noise levels, and excellent fuel economy. They also meet the necessary Environmental Protection Agency (EPA) Tier 4 emissions requirements.

• The 1570, 1575, 1580, and 1585 models are biodiesel compatible from the factory up to B20. The 1550 model requires.

• Key features of the engine include:

• Economical cast-in block cylinder design for good cooling and long life

• Indirect fuel injection (1550)

• Direct fuel injection (1570, 1575, 1580, 1585)

• Injects fuel directly on top of pistons for more efficient combustion

• Delivers more horsepower per gallon of fuel

• Improves starting

• Develops more horsepower per gallon of fuel and improves starting

• 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 gas and noise from the piston slap

• Higher top rings on the piston and a thinner head gasket greatly reduce the volume of unburned waste gases and increase combustion efficiency

• Timing gears and injector drive gears utilize helical profile gears to help lower engine noise; gear teeth have a newly designed roll-off profile, giving almost no clash, no noise, and no backlash

• Fuel filter with replaceable element

• Full-pressure intake manifold provides quick starts in temperatures down to 0°F (-18°C)

• Auto-bleed fuel system – there is no need to prime the system if the tractor runs out of fuel; the system self-primes the injection pump, lines, and injectors, providing fast fuel recovery

• Key start and shutoff eliminates 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

• Enclosed engine compartment to keep out debris and lower sound levels

• Sealed radiator compartment to keep trash and debris on outside of hood

• Excellent torque for plenty of lugging power when operating in tough mowing conditions

• Full-pressure lubrication for positive lubrication, even when operating on slopes

• Dual-element, dry-type, replaceable air cleaner completely sealed for effective cleaning

• 90 percent to 95 percent of dirt ejected before it reaches the paper element

• Secondary safety element for additional filtering

• Progressive-type air restriction indicator to let operator know when the filter needs servicing

• Automotive-type alternator for plenty of charge to the battery and power for accessories

• 75 amp for open-station models

• 95 amp for ComfortCab models

• Automatic initiation of air heater for easier cold-weather starting

• Automotive-sensing system tells operator when engine is ready to start
