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
Mechanical depth adjustmentMechanical 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

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.
