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

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.

• 10-gauge, 0.135-in. (3.42-mm) fabricated steel deck top with added 10-gauge, 0.135-in. (3.42-mm) spindle mounting plate
• 7-gauge, 0.19-in. (4.8-mm) side skirts with reinforcement bar

The fabricated, floating mower deck delivers an extremely high-quality cut in diverse conditions:

TerrainCut Front 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.

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.

Easy-to-operate controls maximize productivity

Maneuverability:

• Turn radius of 13 in. (33 cm)
• Uncut circle of 28 in. (71.1 cm) with a 72-in. (183-cm) 7-Iron™ PRO mower deck
• Deck offset and pulled rearward 
• Tail-follows-the-trail trimming capability with 72-in. (183-cm) side-discharge mower deck
• Steered wheels (tail) stay within the path (trail) cut by the mower deck, allowing maneuverability without the rear of the machine contacting mowing obstacles

Hydrostatic power steering provides the following benefits:

• Makes it easy to turn the unit for less operator fatigue
• Allows quick turns - two turns lock to lock - for excellent productivity

The steering console offers the following:

• Throttle
• Key switch
• Headlight switch
• T4 display for monitoring performance (1570, 1575, 1580, 1585)

Front mower seats have standard suspension with arm rests for added comfort and productivity

Operator comfort enhances productivity. TerrainCut™ Front Mowers include suspension seats with green accents and an embroidered John Deere logo. The comfort-adjust mechanical spring suspension seat is base equipment, and an air-suspension is an optional upgrade. The operator can adjust suspension by increasing or decreasing pressure for optimum comfort. Fore-aft adjustments accommodate both tall and short operators.

Both seats are 24-in. (61-cm) tall and include back-angle, lumbar, and arm rest adjustments. The eye-catching seats are constructed from two unique vinyl textures and sewn with decorative stitching. Retractable seat belts prevent belts from becoming tangled in the seat suspension and controls.

Other comfort features include:

• Standard cup holder
• Noise level meets North American and European standards

Welded frame structure is made of high-strength steel

The revolutionary tubular, high-strength welded steel frame provides durability and allows major components to be located lower in the machine:

• The design results in a lower center of gravity for better stability and traction on hillsides and slopes.

• Rollover protective structures (ROPS) are integral members of the frame.

Durability features of the frame include:

• Heat-treated cast-iron axles with 1.24-in. (3.15-cm) kingpins
• Internal wet-disk brakes
• Hydraulic PTO clutch, with brake
  • Provides smooth engagement and long life
• Hydrostatic oil cooler
• O-ring seal (ORS) hydraulic fittings
• Integrated, shaft-driven power take-off (PTO)
• Sealed relays and electrical connectors
• Heavy-duty, dual hydraulic cylinders
• Nodular cast-iron lift arm sockets
• Cast-iron rear bumper

Hydrostatic transmission and transaxle are heavy-duty to maximize uptime

Two-function mechanical rear-wheel drive for optimum use of the four-wheel drive feature

Mechanical rear-wheel drive is available as standard equipment (1575, 1580, 1585) or as a factory-installed option (1550, 1570):

• On-demand four-wheel drive automatically engages and disengages as needed.
  • Constantly maximizes trimming ability
  • Offers better fuel economy than full-time four-wheel drive 
  • Provides better steering tire wear than full-time four-wheel drive 
  • Increases traction and trimming ability to allow a novice operator to mow like an expert
  • Works in the forward direction only
• Full-time four-wheel drive is on at all times.
  • Can be engaged or disengaged on the go
  • Provides maximum traction and flotation in poor conditions
  • Works in reverse as well as the forward direction
