On every commercial mower deck, there are three 1-in. (25-mm) spindles that are cold-forged and heat-treated for strength. Spindles are supported by precision ball bearings that provide great performance and reliability.

The blade spindles are designed for many hours of trouble-free operation:

  • The spindle housings are made of ductile cast iron and have a gusseted design that puts the reinforcement where it is needed.
  • Ductile cast-iron material provides increased impact strength.
  • 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 assembly can be rebuilt.

Key features of the 7-Iron PRO MOD mower deck:

  • Deck can be converted from a wide-open side discharge mode to a fully chambered mulching mode with a single move of a lever.
  • Deck is stamped from 7-gauge, 0.179-in. (4.5-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup.
  • Significantly fewer welds on the deck shell to wear or break; it is stamped from a single sheet of steel rather than multiple fabrications. Anti-skid step on the deck provides easy machine mounting.
  • Higher blade tip speed than many competitors - 18,000 fpm (5486 m/min) for more blade cuts per inch mowed.
  • 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.
  • The wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
  • 1-in. (25-mm) cold-forged spindles are heat-treated for strength and are supported by ball bearings, providing reliability and performance; ductile cast-iron blade-spindle housings have a gusseted design for extra reinforcement.
  • The front edge is raised above the blade plane to allow even cutting of tall grass and reinforced with a square bar for durability. The front baffle has been redesigned to better manage airflow and control clippings.
  • Dual-captured anti-scalp wheels provide deck flotation over even the toughest terrain.

#

The 60-in. (152-cm) rear-discharge mower is ideally suited for:

  • Areas where people are present
    • Schools
    • Parks
    • Playgrounds
    • Traffic areas (city boulevards, roadsides, etc.)
  • Conditions and application areas with long grass and weeds where wide dispersal of grass (park areas, roadsides, etc.) is not a concern

Some government bids specify that the mower is equipped with a rear discharge deck:

  • Deck is fabricated from 7-gauge, 0.179-in. (4.5-mm) steel for added deck strength and long life.
  • 0.75-in. (1.9-cm) solid steel bar is welded to the mower deck perimeter for additional strength.
  • Deep-deck design increases airflow so more material can be processed.
  • Operator can trim with either side.
  • Unique baffling system that is designed to reduce clumping and windrowing usually associated with rear-discharge mowers.
  • 1-in. to 5-in. (2.54-cm to 12.7-cm) cutting heights, in 0.5-in. (1.3-cm) increments, allow the operator to match mowing conditions.
  • Gauge wheels, rollers, or side-mounted skid shoes lift the deck over uneven surfaces for a well-groomed appearance.
  • Spindles can be greased without removing belt shields.
  • 1-in. (25-mm) cold-forged spindles are reliable.
  • Heat-treating of the spindles provides additional strength.
  • Ductile cast-iron blade-spindle housings have a gusseted design for extra reinforcement.
