Chisel Point Sweeps

8" Hi Rate Sweep

-Shown with optional 3-1/2" tube and clip (2-1/2" hose fits inside).
-8" Wing width.
-Designed for higher rates (5,000 - 10,000 gallons per acre).
-Lifts the soil than 1-1/4".
-Vertical portion 1" thick at the lower rear to create a wider slot to facilitate the filling of the soil
cavity created by the wings.
-The 8" Hi Rate Sweep parts the soil more and creates a larger soil cavity than the 8" Low Rate Sweep
to contain the liquid.

12" Hi Rate Sweep

-Shown with optional 4" tube and clip (3" hose fits inside)
-12" Wing width
-Designed for higher rates (10,000 - 15,000 plus gallons per acre)
-Lifts the soil less than 1-14"
-Vertical portion is 1" thick at the lower rear to create a wider slot to facilitate the filling of the soil
cavity crated by the wings.
-The 12" Hi Rate Sweep parts the soil more and creates a larger soil cavity than the 8" Hi Rate Sweep
to contain the liquid.

Dietrich Complete Sweep/Rotary Injection System


-Easy change over in the field between Sweep & Rotary Injection
-13 Wave Swivel Conical Bladeto widen slot for nutrient placement
-Unique Swivel-mounted Conical Coulter Blade enters the soil parallel to the direction of travel and
exits moving soil laterally resulting in maximum depth penetration for maximum gallons per acre. ----Does not create excesive side load on mounting or tank.
-Individual depth adjustment
-Option to run Coulters deeper behind tank tires in muddy conditions
-Designed for speeds up to 8 MPH
-Available 8" Low Rate, 8" High Rate, or 12" Hi Rate Chisel Point Sweeps depending on your desired
gallons per acre
-Wing drop or 3", 3-1/2", or 4" OD Tube available on all Chisel Point sweeps
-4" Rotary Injection Discharge Tube & Bracket for use with 2-1/2" & 3" hoses.

The Complete Dietrich Conical Blade Rotary/Sweep Injection System Followed by th Dietrich Slurry Clozr

This complete injection system includes the Dietrich Series 70 Assembly with 800# Down Pressure Coulter Assembly, Coulter Mount, 13 Wave Swivel Conical Blade, 4" Rotary Injection Discharge Tube & Bracket, your choice of Chisel Point Sweep & Discharge Tube, and the Dietrich Clozr with choice of Notched Blades.

The vertical tillage industry does no yet know what the maximum gallons per acre will be in wet soil conditions. Wet soil tends to have a plastic characteristic. This condition creates minimal cavity size plus wet soil does not soak up excess liquid.

To get a better perspective of the liquid volume, imagine a circle of liquid 3.8" in diameter will be created in the direction of travel at a 10,000 GPA rate. At 5,000 GPA the circle of liquid is 2.7" in diameter. Now it is possible to inject up to 15,000 gallons or more per acre in any soil condition using Rotary Injection for lower gallons per acre and easily convert to Sweep Injection for wet or compacted soil conditions that limit gallons per acre.

Dietrich Conical Blade Rotary Injector

For Vertical Application:

-Spacing from 30" to 18"
-Fits 6" x 4" & 6" x 6" Tool Bar
-Conical blade enters the soil in the direction of travel ahead of the spindle and moves soil laterally
behind the spindle to widen the opening.
-Heavier down pressure spring
-Coulter swivels reducing side loading
-All service/adjustments accomplished with 1/2" impact wrench
-6" Blade rock clearance to prevent breakage
-Cup washers protect all seals
-Dual roller bearing for longer life, not single row ball bearings
-All hi tensile steel thoughout for weight reduction.
-Weight-forward design to avoid weight transfer from drawbar
-2 coat black enamel baked paint

Dietrich Series 70

-No daily greasing – Only end of season shank pivot greasing
-Snap pin adjust coulter –No set screws
-800# coulter down pressure spring assembly - Most others range from 200 - 350# down pressure
-22 - 1/2" diameter coulter -Not 20"
-Auto reset with heavy duty 1400# reset force - Not spring bundle
-1-1/4" x 2" edge bent steel shank- Not 1" x 2"
-Narrow 1/2" sweep shank - Sweeps lift the soil less than1-1/4"
-Hi carbon, special bar quality, cast steel chisel point sweep with front hi chrome casting and heavy, --Abrasion-resistant hard surfacing on the wings
-Separately replaceable sweeps & tubes
-Cup washers protect all seals

Design Features:

-Series 70 Chisel Point Sweeps are designed to penetrate frozen soil.

-1/2" thick Chisel Point Sweep Shank combined with 62 degree swept back wings results in
minimum soil disturbance and allows shallow placement of nutrients.

-The sweeps are designed with thin Vertical Portion Hi Carbon steel to minimize soil disturbance at
high speeds.

-To prevent breakage, the sweeps are attached to a 1-1/4" x 2" edge bent alloy steel shank to allow
side movements when striking rocks.

-Standard 3", Optional 3-1/2" & 4" OD tubes with clip, and Wing Drop Tube available on all sweep

The Bonus Features:

-Easy snap pin depth adjustment on coulters
-Consistent coulter depth with 800# down pressure coulter assembly
-Longer wear & better cutting action with larger coulter blades and special edge detail
-Requires only end of season greasing on shank pivot


-Since Hog Manure is worth approximately $48 & Dairy Manure $31 per 1,000 gallons at current pricing, it is a valuable resource that should be used in the most efficient way possible.

-All agronomists agree nutrients should be placed in the
GREEN ZONE 5"–6" deep for maximum yield.

-Surface soil dries. Plants don't get nutrients in dry soil.
-Weeds germinate easier in fertile surface soil.

-Injecting deeper than the GREEN ZONE creates less nutrient availability and increases fuel consumption.
