**Fragile residue includes crops like soybeans, edible beans, peas, wheat (under 45 bu), sunflower, peanuts, cotton.

Coulter gangs

Coulter gangs
Coulter 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.

Long, narrow hitch for good maneuverability in tight headlands

714 long, narrow hitch
714 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.

Three-bar frames offer strength

Three-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

Crank-adjust depth control available

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

Variety of ground-engaging tools available to match conditions

Shovels and points
Shovels 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.
