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
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.
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
Three-bar frames offer strength
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
Long, narrow hitch for good maneuverability in tight headlands
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.
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.
Choice of rigid, spring-reset, or Tru-Depth™ standards
Rigid standard (figure 1):
In base equipment on all models
32 mm x 51 mm x 813 mm (1.25 in. x 2 in. x 32 in.)
