Serviceability is designed-in to reduce maintenance cost and increase uptime

Engine hood

Large screened area of engine hood

Hood latch

Engine hood includes large screened area:

Minimizes the amount of material that can get to the cooling radiators
Minimizes the need to clean the hood screens

Hood latch keeps the hood securely in place, providing an optimum seal:

A single hood latch is located on top of the hood behind the seat.

Engine hood opens to the rear

Designed-in service accessibility

Designed-in service accessibility helps ensure daily maintenance is completed to keep the machine operating at peak performance.

The hood opens rearward, exposing the following:

Engine
Oil and fuel filter
Hydraulic oil cooler
Radiator check/fill

The hood can be totally removed, if necessary. The seat flips forward for access to air filter, fuse bank, engine oil dipstick, and front of engine.

Condenser release knob

Condenser tilted back to permit cleaning

Easy-to-turn knobs are provided to release the air conditioning condenser (1575 and 1585 only) and fuel and hydraulic oil coolers so they can be tilted back to permit thorough cleaning between them and the engine coolant radiator.

Quick response (QR) codes link to owner information web pages

QR code label on control console

To speed access to owner information web pages, a QR code is printed onto a product identification number (PIN) label located on the control console near the seat. The owner information web pages that include links to:

Safety and how-to videos
Operator’s manuals
Parts catalogs
Maintenance reminder sheets

Warranty statements

Foot platform access panel

Removable foot platform

The panel on the foot platform can be removed for access to the transaxle, PTO shaft, and most linkages.

Easy-to-read daily service decal is located on the bottom of the foot platform panel:

Provides access to easily hook up driveshaft when changing implements
Makes it more likely service will be performed at the optimum time, thus ensuring the highest level of performance and uptime

Panel on foot platform removed

Removal of the foot platform gives convenient access to the driveshaft that powers the mower deck, snow blower and rotary broom:

Helps make changing from one front implement to another easier and more convenient

Hydraulic hoses have reusable O-ring seal (ORS) fittings:

ORS fittings seal at a lower torque to prevent leaks.
Fittings can be removed from a damaged hose and installed on another hose.
Downtime and cost for repairs are reduced considerably.

Rotate For Service™ (RFS) feature shown

RFS service lockout latch

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

The service-latch pin allows mower deck to lock into position to ensure deck is held in position for cleaning or service.
The top-greaseable spindle grease fittings can be accessed without removing the belt covers.

Trailering features are included to reduce the time and cost to move equipment

Trailering features are designed-in for convenience:

Designed-in trailer tie-downs are located at the front and rear of the machine.
26-degree deck lift will clear the steepest trailer ramps for easy loading and unloading.
Rotate For Service™ (RFS) decks take up less room when transporting on trailers, allowing more room for other important equipment.

Remote battery posts

Remote battery posts simplify jump starting. Both positive and negative posts are located in front of the right rear steer tire.

Welded frame structure is made of high-strength steel

High-strength, tubular steel frame

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.

Durable design

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

Kanzaki 30-cc transmission

A Kanzaki® 30-cc transmission is used for reliable operation.

Durability features include the following:

High-capacity hydrostatic transmission and heavy-duty transaxle maximize performance and uptime and minimize cost of maintenance.
Charge pump is used to efficiently deliver oil to the transmission.
Oil cooler helps maintain optimum transmission oil temperature for superior performance and longer transmission life in the most challenging operating conditions.
Maximum forward top speed is 12 mph (19.3 km/h) on the 1550, 1570, and 1575 and 15 mph (24.1 km/h) on the 1580 and 1585.
Self-bleeding design helps keep air out of the system.

Kanzaki is a trademark of Kanzaki Kokyukoki Manufacturing Company.

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

Mechanical rear-wheel drive axle

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
Two-wheel drive position is available on 1580 and 1585 with two-speed transaxle.
- Disengages rear axle when transporting at high ground speeds

Dual drive tires are available to optimize performance in challenging conditions (1550 and 1570 only)

Dual drive tires

Dual 23x8.5-12 drive tires are available for increased hillside stability, flotation, and reduced ground compaction.

In addition, single drive tires may be set in the narrow or wide position to match mowing conditions.

NOTE: These tires are available for the 1550 and 1570 models only.

Tail-follows-the-trail design helps avoid obstacles in turns

Tail follows the trail

1585 TerrainCut™ Front Mower

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. (71cm) with a 72-in. (183-cm) 7-Iron 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 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.
