Simple gang depth adjustment
Mechanical 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 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
Long, narrow hitch for good maneuverability in tight headlands
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.

*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.
Variety of ground-engaging tools available to match conditions
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.
Crank-adjust depth control available
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 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.
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
