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 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 (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

Fuel tank features:

• 16-U.S. gal. (60.6-L) capacity provides a 10-hour run time.
• Top draw provides clean fuel.
• Fuel indicator is conveniently located.

Mower decks for TerrainCut™ Front Mowers match a wide variety of needs

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

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.

Rotate for Service (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.

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.

Features include:

• Blade tip speed of 18,000 fpm (5486 m/min) for more blade strikes per inch mowed.
• Trim-edge bumper reduces damage to the mower deck and property.
• Redesigned front baffle manages airflow and controls clippings better.
• Blade spindle housings are made of ductile cast iron
  • Gusseted design puts reinforcement where it is needed.
• Spindle pocket reinforcement gives even greater structural durability.
• Adjustable anti-scalp wheels help smooth out the mowing job.
• Standard semi-pneumatic caster tires will not go flat from punctures.

The mower is designed to provide exceptional cut quality at higher travel speeds:

• The mower deck is stamped from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup.
  • Provides precision components and long deck life
  • Single piece of steel means no welds to break
  • 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.

The 62-in. (157-cm) FastBack rear-discharge mower is ideally suited for:

• Areas where people are present
  • Schools
  • Parks
  • Playgrounds
  • Traffic areas (city boulevards, roadsides, etc.)
• Conditions and applications:
  •  Areas with long grass and weeds
  • Areas where customer is not as concerned about having a wide dispersal of grass (park areas, roadsides, etc.)
• Government bids that specify a rear discharge mower. 

Key features of the 62-in. (157-cm) Rear-Discharge Mower Deck include: 

• Mower deck is constructed of 7-gauge, 0.179-in. (4.6-mm) steel for the strength to stand up to the demanding use of commercial and municipal mowing applications.
• Blade spindle housings are made of ductile cast iron.
  • Gusseted design puts reinforcement where it is needed.
• Deck is constructed with a  unique baffling system that reduces clumping and windrowing and produces a finished appearance that competitive rear-discharge mowers cannot match.
• The belt-drive system has an easy-to-adjust tension device.
  • By using a spring system, the risk for over tensioning is eliminated, ensuring a long belt life and excellent performance during the season.
• For easy service and maintenance, the deck can be rotated into the vertical locked service position.
• Deep-deck design increases airflow so more material can be processed.
• Operator can trim with either side.
  • Dual side trimming increases operator productivity.
• 1-in. to 6-in. (2.5-cm to 15.2-cm) cutting heights, in 0.5-in. (1.3-cm) increments, allow the operator to match all mowing conditions.
• Gauge wheels, rollers, or side-mounted skid shoes lift the deck over uneven surfaces for a well-groomed appearance.
• Double-captured anti-scalp wheels provide increased durability.
• Easy lift and lock system for service purposes.
• Standard semi-pneumatic caster tires will not go flat when punctured.
• Spindles can be greased without removing belt shields.
• 1-in. (2.5-cm) cold-forged spindles are strong for long life.
• Heat-treated to provide additional strength
• Certified to European (CE) standards
