Like roots in a too-small container, your performance would be less than its best if you had to live and work each day in such cramped spaces. Yields suffer when compaction keeps roots from growing freely into the subsoil for optimum nutrient and water uptake. The Zone-Builder subsoiler from Unverferth lets plants stretch their legs (and their roots) by opening passageways through the hardpan with minimal surface disruption. Long-term university research confirms deep-tilling with tools such as the Zone-Builder implement raise yields and income.

Three different Zone-Builder subsoiler models to best suit your soil conditions:
o Model 132 with auto-reset shank that trips rearward and upward from a single pivot point for trouble-free use in rocky, hard soils. Trip pressure of 6,000 lbs. for consistent working depth

Straight-leg shank design creates a passageway that allows plant roots, soil moisture and nutrients to move freely into the subsoil with minimal surface soil disturbance

Slices up to 20" deep to alleviate the deepest compaction

3/4" thick high-stress,forged-alloy shanks provide maximum strength and minimal disturbance

Heat-treated, austempered 1-3/4" wide replaceable points dig through the hardpan

Points feature raised-center, tapered design for less soil disturbance at higher speeds

Hourglass-shaped, heat-treated cast invertible wearbars add to shank durability and subsurface soil fracturing

Heavy-duty, double-frame all-welded construction with 6"x6" rearbar and 38" underframe clearance provides ideal residue flow

Standard tool-free adjustable stabilizer wheels with stubble-resistant tires assure a consistent working depth

Front-mounted swivel coulters with 1,500 lbs. of downpressure easily cut through the heaviest residue and features heavy-duty 6-bolt hubs with recessed endcaps and ride on a lip for increased durability

Models available with 2-16 shanks with a powder-coat finish in choice of red or green

Strip-Builder attachment for added tillage and leveling
o Width, angle and depth adjustable to create a mound of tilled soil for faster warmup
o Coulter blades ride on heavy-duty 6-bolt hub with recessed endcaps for greater longevity and are available in wavy, concave notched or concave smooth blades
o Optional 15" Rolling Harrow basket with serrated blades helps break up clods and levels for a receptive seedbed - available with straight or concave blades
o Strip Builders can also be equipped with 17" wide, four section zone-firming press wheels

Zone-Firmer press wheels feature easily adjusted downpressure from 0-360 pound to create a more level soil surface. A zone firmer with leading angled press wheels followed by four section press wheels is also available.

Full-width Rolling Harrow soil conditioner for 3-9 shank models helps to chop and distribute residue

Full-width 13" Spiked Drum leveler for models 132 are available to fit 4-8 shank models features 3" spiraled drive lugs for added leveling and residue incorporation.

Double toolbar mounted coulter attachment provides added residue sizing and incorporation in between the shanks for cutting every 10" across the front of the machine. Available for 3 through 9 shank models.

Shank Customizers
o Shatter wings can be mounted at either of two locations for increased soil and hardpan fracturing. Wing slope can be set from 0 degrees to 14 degrees
o 1/4-inch thick, bolt-on shank protectors for use in abrasive soils
o Fertilizer injectors for NH3 and liquid fertilizer easily attach to rear of shank and include shank protection
o Dry fertilizer tube attachments also feature shank protectors and are left or right hand mounted

Rear-Mounted hitch provides ability to tow fertilizer tanks and for easier fertilizer placement

Row markers feature notched blades that leave a highly visible mark to maintain accurate row spacing

Lighting package for safer road transport comes complete with lights and reflective striping to meet current standards

Shank stagger kit for increasing residue flow and reducing horsepower requirements

Coulters are positioned directly ahead of shanks for optimum residue flow
1,500 lbs. of downpressure easily cuts through the heaviest residue
Blades ride on 6-bolt hub for extra durability
Pick your choice of 20 rippled or 24 straight blades to match soil conditions
Cast coulter mounting clamps feature bi-directional clamping for keeping the blade in line with the shank for minimal soil disturbance
Two heavy-duty tapered roller bearings protected with triple-lip seals, O-rings and recessed hub caps with retaining rings for long-term, trouble-free use

3/4-wide design shatters hardpan up to 20 deep
1 raised-center point with tapered design for less soil disturbance at higher speeds
Full-length heat-treated cast invertible wearbar with hourglass design (narrower at center) for easily slicing through soil with minimal disturbance to the soil surface
Heat-treated, austempered steel points for greater life
Exclusive boot-style point design surrounds shank base for greater stability and extended life

Field-proven auto-reset shanks with up to 6,000 lbs. trip force specifically designed for use in rocky, lighter soils
Features wider, heavy-duty cast pull-arm for greater stability and strength
