2025 John Deere Golf & Sports Turf 1550 72 in. 7-Iron™ PRO side discharge

• 7-Iron™ PRO Side Discharge or Fastback™ Rear Discharge Deck
• Diesel Engine
• Biodiesel Conversion Kit available
• Compatible with select front blade, snow blower and broom attachments

Features May Include: 

• 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.

• 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.

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.

The mower spindle housings are made of ductile cast iron.
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.

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.

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.

• 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)

Console information/warning lights include the following:

• Hour meter
• Battery discharge light
• Engine oil pressure
• Engine coolant temperature
• Hydraulic oil over temperature
• Air preheater
• Lights
• Power take-off (PTO) operation indication

• 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
