1580 terraincut mower

Hood open for access to engine

3-cylinder, liquid-cooled diesel engine

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.

Models 1570, 1575, 1580, and 1585 are biodiesel compatible from the factory up to B20. Model 1550 requires an optional kit to be compatible with B20 biodiesel fuel.

Key features of the engine include:

• Economical cast-in block cylinder design for good cooling and long life
• Indirect fuel injection (model 1550)
• Direct fuel injection (model 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; 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 will assist 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 will self-prime 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

Two-speed transaxle shift lever is standard on 1580 and 1585.

Safety starting system

TerrainCut™ Front Mowers have an operator-presence system.

To start the engine the following conditions must be met:

• Master brake must be depressed or the parking brake locked; the hydrostatic foot controls will then be in the neutral position.
• PTO must be disengaged
• Ignition key must be used.

In addition, once the engine is running, an interlock automatically shuts the engine and PTO off if the operator leaves the seat. To keep the engine running, the operator must disengage the PTO and set the parking brake before dismounting.

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 (R66949) 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™)

Mower deck showing RFS feature

Rotate for Service (RFS) feature provides access for cleaning and maintenance of the mower decks:

• 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 Rotate for Service position also reduces the length of the machine for trailering.

Certification

TerrainCut Front Mowers comply with ANSI B71.4 safety certification.

Heavy-duty blade spindles

Cast-iron spindle housing

Cast-iron spindle housing

The mower spindle housings are made of ductile cast iron, except for the 72-in. (183-cm) 7-Iron V-Flex Side-Discharge Mower Deck, which has an aluminum center spindle housing and cast-iron gearboxes to drive the outer blades.

Key benefits of ductile cast-iron spindle housings:

• Ductile cast-iron material provides superior impact strength.
• Gusseted design puts reinforcement where it is needed.
• Strength of cast iron protects against damage from blade impacts.
• Grease fitting is mounted at the top for easy access.
• Grease pressure-relief valve minimizes seal damage from overfilling with grease and keeps debris from entering housing.
• The 8-in. (20.3-cm) diameter housing distributes loads and impacts to minimize deck-shell damage.
• Spindle allows ability to be rebuilt.

NOTE: The 72-in. (183-cm) 7-Iron V-Flex Side-Discharge Mower Deck has an aluminum center spindle housing. The outside blades are driven by cast-iron gearboxes.

  • Provides a smooth underside, without corners, reducing material buildup
• 0.75-in. (1.9-cm) solid steel bar is welded to mower deck perimeter for added strength.
• The rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
• A deep-deck design of 5.5-in. (14-cm) delivers excellent airflow so material can be processed quickly and efficiently.
• 1-in. to 6-in. (2.5-cm to 12.7-cm) cutting heights, in 0.5-in. (1.3-cm) increments, allow the operator to match all mowing conditions.

Unique baffling system allows grass to stand up before being cut, producing a uniform length and appearance:

• Baffling system eliminates clumping, blowout, and windrowing.
• Wide discharge opening provides even clipping dispersal for an excellent, finished appearance in all conditions.

• The top-greaseable spindle grease fittings can be accessed without removing the belt covers. 

Front mowers must be properly ballasted for both good performance and safe operation. Ballast requirements differ depending on the front mower model and the implement being used.

The chart below gives the minimum ballast requirements for the various product configurations. Additional ballast is recommended for operating on slopes or other conditions that may warrant it.

NOTE: Use only implements and accessories recommended by the manufacturer.
