Features
Diesel engine has high-quality features to minimize operating cost
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 theEnvironmental Protection Agency (EPA) Tier4 emissions requirements.
Models 1570, 1575, 1580, and 1585 are biodiesel compatible from the factory up to B20. Model 1550 requires an optionalkit 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
- 90percentto 95percent of dirt ejected before it reaches the paper element

1550 Front Mower with 60-in. (152-cm) mower deck 
1550 Front Mower with 72-in. (183-cm) mower deck Tail-follows-the-trail trimming with 72-in. (183-cm)mower decks. Steered wheels (tail) stay within the path (trail) cut by the mower deck, allowing maneuverability without the rear of the machine contacting mowing obstacles.
Maneuverability:
- Turn radius - 13 in. (33 cm)
- Uncut circle - 28 in. (71 cm)with a 72-in. (183-cm)PRO mower deck
- Deck offset for increased trim capability

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