Extra durability and mowing performance from 7-Iron™ PRO Side-Discharge decks pressed from a single piece of steel

Key features of the 7-Iron PRO mower deck:

• Deck is forged 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.
• Significantly fewer welds on the deck shell to wear or break - it is forged from a single sheet of steel rather than multiple fabrications. An anti-skid step on the deck provides easy machine mounting.
• Extra reliability and long life with cast-iron blade spindle housings.
• Higher blade tip speed than many competitors - approximately 18,500 fpm (5,639 m/min) for more blade cuts per inch mowed.
• 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.
• Quick-release belt covers do not require tools or the removal of a ring clip; just lift one corner of the cover and rotate it slightly to remove.
  • A hole in the deck tab is provided for use of an optional ring clip for extra security, if desired.
  • This makes it quick and easy for you to clean out trash that may collect around the spindle sheave.
