The Ripper-Stripper® strip-tillage tool’s wide variety of coulter options, finishing attachments and accessories allow the operator to customize the tool to fit their individual needs due to the varying soil profiles depending on geographical region.  The Ripper-Stripper is available in two models: the auto-reset model that automatically resets the shank into the soil after coming into contact with an obstacle or the cover crop roller with smooth coulter blades and rubber-cushioned mounting that crimps and deflects residue away from the row.  The Ripper Stripper strip-tillage tool from Unverferth does it all—in one pass—spring or fall—whether cutting through the prior year's crop or cover crop residue.

Create a seedbed that warms quickly, provides optimum seed-to-soil contact for enhanced early plant growth and makes it easier for the plant roots to get the moisture and nutrients that are needed.

Ripper Models


The Ripper-Stripper is available in 2/4/6/8-shank with a rigid frame or 8/12/16-shank with a folding frame.  Depending on the number of shanks, 30”, 36”, 38” and 40” row-spacings are available.

Model 312 features a shear-bolt trip design for use in soils with minimal obstacles.  The trip pressure for Model 312 is 7,500 lbs. for consistent working depth.

Model 332 features an auto-reset trip design with a heavy-duty pull arm that can trip upward and rearward to avoid obstacles and quickly resets without the need for shear-bolt replacement.  The trip pressure for Model 332 is 6,000 lbs. for consistent working depth.


The heavy-duty, double frame with a 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.

Parking stands are standard on all units.  Transport lighting and reflective markings are standard on all Ripper-Stripper models except optional on 2-row sizes for safer road travel.

3-Point Hitch

Depending on model, the Ripper-Stripper has 3 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 pull-type package or 3-point implement caddy to reduce side stress on the frame.  Adaptor kits for standard CAT 2 hitches are also available.

Stabilizer Wheels

Stabilizer wheels provide added stability and tool-free adjustment for quick and convenient depth adjustment in the field.  Rigid models up to 6-row 30” row-spacing utilize 7.60L x 15 8-ply tire, 8-row folding and 6-row 36”, 38” and 8-row 30” rigid models utilize 9.5L x 15 8-ply tires, while models that are 12-row 30” row-spacing (wings only), 12-row 36”, 38” 40” row-spacing and 16-row 30” row-spacing (base and wings) folding models utilize 12.5L x 15 10-ply tires.


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 13 waves cut residue with 1,500 lbs. of down force.

6-bolt greaseable hubs with 5 layers of seal protection help ensure long-term, trouble-free use along with patented formed cast mounting clamps ensure that the lead Coulter stays straight in the field.

Ripper Cover Crop Roller

Cover Crop Roller

The cover crop roller is available on 6/8-shank rigid and 8/12-shank folding (30”/36”/38” row spacings) features chevron-patterned blades that crimp and deflect cover crop away from the row.

Smooth blades (22” diameter) on the cover crop roller (11” diameter) create a clear path for the shank and rubber-cushioned mounting allows the individual rollers to follow ground contours and go over obstacles.


Shank Features

Shanks on all models feature special-alloy, steep-sloped ¾” shanks that loosen compaction up to 18” deep for shattering hardpan.  The recommended pulling requirements are 20-40 HP per shank depending on soil type.

1 ¼” wide patented shark-fin wear bars extend the shank life and minimizes resistance for easier pulling.  Replaceable raised-center shark-fin points break hardpan with minimal surface soil disturbance and greater durability.

Stripper Attachments


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