FRAME

TILLAGE WITH A PURPOSE

Yields suffer when compaction prevents plant roots from growing freely throughout the soil in search of moisture and nutrients. The Unverferth Zone-Builder® subsoiler lets plants stretch their legs (and their roots) by opening passageways through the hardpan with minimal soil disturbance.

MODELS

The Zone-Builder Subsoiler is available in 2-, 3-, 4-, 5-, 6-, 7-, 8-, and 9-shanks with a rigid frame or 7-, 8-, 9-, 10-, 11-, 12-, 13- and 16-shanks with a folding frame. Depending on the number of shanks, 24”, 30”, 36”, 38”, 40” and 60” row-spacings are available.

CONSTRUCTION

The heavy-duty, double frame with 6” x 6” rear mounting bar provides years of maximum durability when traveling in and out of the field. The frame is powder-coated in your choice of tractor red or green on all sizes for a long-lasting finish.

3-POINT HITCH

Depending on model, the Zone-Builder has different hitch styles which include 3-point hitch, quick attach hitch and narrow quick attach hitch. When pulling with oscillating 4WD track tractors, choose the optional 3-point implement caddy to reduce side stress on the frame.

STABILIZER WHEELS

Stabilizer wheels with 6-bolt hubs provide added stability and tool-free adjustment for quick and convenient depth adjustment in the field. Rigid models utilize 7.60 x 15 8-ply tires, folding models up to 25’ working width utilize 9.5L x 15 8-ply and folding models with 12 to 16 row 30’-40‘ working widths utilizes 12.5L x 15 10-ply tires.

COULTER

LEAD COULTER

The lead coulter features a swivel design for 10 degrees of side-to-side movement to follow ground contours and changing terrain. The 20” blade with rippled waves cuts residue with 1,500 lbs. of downforce. On models 132 and 112, the lead coulter features 24” straight blade with 1,500 lbs. of downforce.

SHANK

SHANK FEATURES

Shanks on all models feature special-alloy, steep-sloped ¾” shanks that loosen compaction up to 20” deep for shattering hardpan. The recommended pulling requirements are 30-50 HP per shank depending on soil type.

ATTACHMENT OPTIONS

PARALLEL-LINK MOUNTING

All Strip Builder/Zone-Firmer attachments feature parallel-link mounting for consistent operating depth across the field and are width, depth and down-pressure adjustable. All pivot points feature hardened steel bushings for reduced maintenance.

ROLLING HARROW BASKET

Choose from 15” wide Rolling Harrow basket attachments with lead wavy, notched or concave coulter blades or a full width 16” diameter rolling basket or drum attachment for your Zone Builder. 15”-wide strip builders create a fully tilled and leveled strip of soil ready for planting while the full width basket or cleated drum attachments mulch and level the soil.

STRIP BUILDER

17” wide wavy blade strip builder features two adjustable coulters ideal for preparing rough-textured seedbeds.
