1585 TerrainCut™

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 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 an optional kit to be compatible with B20 biodiesel fuel.

	1550	1570, 1575, 1580, 1585
Fuel	Diesel (optional kit permits B20 compatibility)	Diesel (B20 compatible)
Gross power at maximum rpm	25 hp (18.4 kW), PS	37.4 hp (27.5 kW), PS
Displacement	77 cu in. (1.262 L)	100.2 cu in. (1.642 L)

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) (optional engine coolant heater attachment assists starting under more extreme conditions)
• 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

Rear-mounted radiators

Fuel tank is large capacity with convenient gauge for maximum uptime

Since 1998 the John Deere 7-Iron™ mower deck has demonstrated commercial quality, performance, and durability. The 7-Iron PRO, Fastback™, and V-Flex mower decks deliver an even higher-quality cut in even more diverse conditions.

TerrainCut Commercial Mower Compatibility

 

Rear weights (UC13263) are required based on machine configuration. Must also order TCB10303, rear weight mounting bracket.

*Mower deck offset for trimming capability. Vehicle track width is 2 in. (5.1 cm) wider on the discharge side of deck. This may cause the tire to drive over uncut grass on discharge side of deck.

NOTE: These mower decks will not retrofit to F900 Series or F1145 Front Mowers.

Rotate for Service (RFS)

RFS feature provides access for cleaning and maintenance of the mower decks:

• The rotation angle will vary depending on deck size and power unit tire size.
• No tools are required to access belts.
• The underside of the mower deck is easy to access.
• Easy on/off design simplifies installing and removing mower decks.
• Top, greaseable spindles can be accessed without removing belt covers.

The RFS position also reduces the length of the machine for trailering.

Certification

TerrainCut Front Mowers comply with ANSI B71.4 safety certification and ISO 5395.
