  • Three-bar frames offer strength
    Three-bar frame of the 714 Mulch TillerThree-bar frame of the 714 Mulch Tiller

    The three-bar frame:

    • Is constructed of three ranks of standards
    • Has strength to match higher horsepower tractors
    • Handles heavier residue levels

    Three-bar frame models have these strength features:

    • One-piece welded construction
    • Solid steel in rear mainframe member
    • 102-mm x 102-mm (4-in. x 4-in.) cross members
    • 51-mm x 102-mm (2-in. x 4-in.) side members
    • 76-mm x 127-mm (3-in. x 5-in.) diagonal frame supports
  • Simple gang depth adjustment

    The three-bar disk gang model features a mechanical depth adjustment:

    • Depth adjuster bolts (1) allow adjustment of individual gangs up or down within a 140-mm (5.5-in.) range.
    Hydraulic depth adjustmentHydraulic depth adjustment
    #

    An optional hydraulic depth adjustment (2) is available:

    • Allows on-the-go hydraulic adjustments to be made from the tractor seat
    • Gangs adjust up or down within a 140-mm (5.5-in.) range
  • Crank-adjust depth control available
    Simple, one-location depth control Simple, one-location depth control
    #

    The crank-adjust single-point depth control is standard equipment on all models and offers the following benefits:

    • More precise adjustment when changing the operating depth
    • Easy access at the front of the machine
    • Accurate, repeatable depth control
  • Choice of rigid, spring-reset, or Tru-Depth™ standards

    •  Excellent clearance to handle heavy trash
      • 813 mm (32 in.) of underframe clearance 
      • 381-mm (15-in.) center-to-center spacing
  • Remaining residue cover

    Typical percents of residue cover remaining are listed in the table. The percentages do not take into account variables such as the condition of the residue, speed and soil type.

    *Non-fragile residue includes crops like corn, sorghum, wheat (more than 45 bu).
    **Fragile residue includes crops like soybeans, edible beans, peas, wheat (under 45 bu), sunflower, peanuts, cotton.

  • Coulter gangs
    Coulter gangsCoulter gangs
    #

    Coulter blades are for use where little incorporation is desired or for erosion-prone areas where it is important to disturb as little residue as possible. Blades are on 229-mm (9-in.) spacing to reduce the chance of plugging.

    • Two-position blade down-pressure adjustment ensures consistent blade down pressure in light- or heavy-residue conditions.
    • Coulter gangs have rigid scraper bars.
    • Dura-Flex™ bearings and welded steel spools provide reliable performance and durability.
    • Gangs are spring-cushioned with 140 mm (5.5 in.) of vertical travel to provide protection against rocks or other obstructions.
  • Variety of ground-engaging tools available to match conditions
    Shovels and pointsShovels and points

    A variety of shovels are available to match conditions:

    • 76-mm x 610-mm (3-in. x 24-in.) concave twisted shovels for use in a wide range of average soil conditions are base equipment.
    • 102-mm x 610-mm (4-in. x 24-in.) concave twisted shovels for use in light, sandy soils or where greater fracturing between the standards is desired, are optional equipment.
    • 51-mm x 305-mm (2-in. x 12-in.) chrome carbide point chisel provides excellent strength and wear life in tough-to-penetrate conditions.
  • Long, narrow hitch for good maneuverability in tight headlands
    714 long, narrow hitch714 long, narrow hitch

    The long narrow hitch design:

    • Allows good maneuverability in tight headlands
    • Is constructed of 51-mm x 127-mm (2-in. x 5-in.) steel tubing for strength
    • Heavy cast-steel hitch link for yoke-type drawbars is standard equipment
    • Hitch clevis is available for use with straight drawbars (not recommended for tractors over 150 engine hp)

    A Level-lift™ linkage with easy turnbuckle leveling enables the mulch tiller to remain level whether in transport or in the field position.

     

    A hitch jack is included with all models for storage and easier hookup to the tractor.
