    Features include:

    • Blade tip speed of 18,000 fpm (5486 m/min) for more blade strikes per inch mowed.
    • 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.

    Safety starting system

    TerrainCut™ Front Mowers have an operator-presence system.

     

    To start the engine the following conditions must be met:

    • Master brake must be depressed or the parking brake locked; the hydrostatic foot controls will then be in the neutral position.
    • PTO must be disengaged
    • Ignition key must be used.

    In addition, once the engine is running, an interlock automatically shuts the engine and PTO off if the operator leaves the seat. To keep the engine running, the operator must disengage the PTO and set the parking brake before dismounting.
