DISC CHISEL

Shatter What’s Hiding Below

Your Soil Surface.


Compaction elimination at its

finest. ..

deep tillage with minimal

residue disturbance.

4110

Compaction can rob yields. Grazing cattle, harvesting equipment and other field traffic compacts your

soil, which can inhibit deep root growth. The 4110 Coulter Ripper was developed to Crack Your

Compaction Problem while leaving maximum residue on the surface. The front mounted coulter

blades, spaced on 7-1/2” centers, size residue and create fracture lines that reduce clod size and stabilize

the overall ripper. A combination of 50 pound cast iron coulter spacing spools and extra heavy frame

members take the bounce right out of this pull-type ripper. No need to load these frames with ballast

– the weight is built in!

Each coulter separating spool weighs 50 lbs.,

providing enough weight to slice through

heavy residue and surface compaction.

Coulter gangs size-up residue

to eliminate plugging or need

for shredding or discing before

ripping.

Well braced "over the top" hitch adds

down pressure to the ripper frame,

providing adequate room for coulter

movement and resists the "roll-over"

forces common to deep till tools.

Standard hydraulic coulter

gangs can be adjusted "onthe-go"

to varying field residue

conditions.

4110 Shank

Operation:

• Operate the coulter ripper when the soil

is dry for maximum shattering between

shanks.

• Find your compaction layer and rip 1-2”

below the compacted layer.

• Ripping deeper will not provide the

maximum shattering and will waste fuel.

Optional Shatter Wing

increases horizontal

fracturing ability by lifting

soil up and forward during

operation.

Auto-Reset

Parabolic Shanks

A maximum point load of 3,500

lbs. with operating depths of

up to 16"-18". Parabolic shanks

provide a wider shattering

pattern and require less draft

than a straight shank.

would miss. With coulters spaced every 7-1/2" and shanks on 15" centers, not much gets by this

complete chisel.

UHMW technology around the

rock shafts means no greasing

needed, dependable

performance

and less parts

leave behind.

Higher plant populations and genetically modified hybrids have contributed to a growing residue

problem that you are faced with. The key to breaking down residue is properly sizing and mixing it in

4511/4530

the top few inches of soil. The New 4500 Series Disc Chisel from Sunflower is aggressive enough to

handle even the toughest residue conditions. Hydraulically adjustable front and rear disc gangs can be

changed independently of each other, enabling you to fine tune your machine from field to field. Chisel

shanks are spaced on 15” centers and will reach a depth up to 12-14”, and are strategically placed for

optimum residue flow. The individually mounted front disc blades will size and mix the residue, while

the shanks will fracture the compaction up to 12-14” deep and the rear gangs will provide the finish

you desire.

*Patent # 6,158,523

Eliminate compaction while

covering more

acres than traditional primary

tillage tools.

2433

When compaction is present, the best time for dealing with it is in the fall during your post harvest

tillage operation. Breaking up the hardpan and roughing up the surface will improve water and nutrient

infiltration over the winter. The Model 2433 Chisel from Sunflower will help you eliminate your

compaction problem while allowing you to cover a large number of acres. With shanks spaced on 12”

centers, the 2433 provides good soil mixing and residue flow* while shattering the compaction up to

10” deep.

*Note: Prior residue sizing may be needed

Straight talk on crop residue management

"Carbon management

in the

Bt era."

By Dr. Rob Zemenchik, CCA

It’s a pretty sure bet that you’re experiencing more

“trash” challenges, maybe quite a bit more, than ever

before. There are several reasons for this:

• University studies show lignin content

(the “glue-like” substance that holds plant cells

together) of Bt corn to be 33 to 97 percent

higher than in traditional, non-Bt hybrids.

That’s why Bt corn is harder to work through

your machinery than before.

• Since today’s full-season hybrids and higher

populations contribute to higher trend-line

yields, there’s more residue than ever in your

fields.

• Today’s plants frequently show stay-green

characteristics at maturity, thus tougher to

manage.

• Year-to-year yield volatility has increased, and

with it the amount of residue produced, so

annual field operations are less routine and

should be adjusted accordingly.

Over the years, fall tillage has been largely a soil

compaction management tool. Now tillage is

becoming equally important, if not more so, as a crop

reside management tool. This is especially true the

farther north you farm, as residue decomposition is of

necessity assisted by mechanical means.

A 200-bushel corn crop can leave four to six tons of

residue an acre behind your combine. Conservation

compliance goals vary from field to field. However,

to leave approximately two tons or so on the surface

at planting from such a crop you’d have the challenge

of properly sizing, mixing, and decomposing two to

four tons of trash an acre.

Helping you in this task are the millions of

microorganisms in every teaspoon of soil. These

“bugs”, along with soil moisture, warm temperature,

and residual nitrogen not utilized by the crop,

are ready to work on your crop residue. But, rest

assured, the decomposition process is much slower

if you don’t incorporate residues. That’s because

sizing and mixing assist decomposition—90 percent

a biological process.

Nutrients cycled in this manner, in high-yield

environments, build soil organic matter and offset

CO2 losses said to be given off by tillage. Another

important factor is timing. Once your combine leaves

the field and your soil testing and fertilization are

complete, do yourself a big favor by immediately

tackling the residue. Biological action ceases at 4°C

or 40°F. In high yield continuous corn, supplemental

nitrogen is often applied at 20 pounds of nitrogen per

ton of residue. Dry forms are okay if you incorporate.

Note that you can refine this nitrogen rate with stalk

tests if time and expense permit.

As for tillage depth, keep in mind that there’s

no magical number of inches to go down. This

depth should always be dictated by economics in

combination with attention to encountering or even

introducing possible soil problems related to alkali

subsoils, clay-like subsurface horizons, or inadequate

mixing that can lead to nutrient stratification. Some

tillage systems promote ultra-deep tillage or vertical

tillage without addressing how applied, immobile

nutrients are to get to the root zone. Water benefits

are achieved at the expense of nutrient placement.

According to university research in the Midwest,

soil compaction rarely, if ever, exceeds a 16-inch

depth, sprayer ruts notwithstanding. The thumbrule

is to set the points to run one-and-a-half inches or so

below the detectable hard pan. Incidentally, today

hard pan is caused most often by traffic rather than by

former ground engaging practices such as moldboard

plowing. For maximum effective corn emergence in

the spring, you want the clod sizes out the back of

your fall tillage tool to be six inches or less on dark

prairie soils and slightly less on forest soils.

This output target is sufficient along with the benefits

of overwintering on soil roughness. Larger clods

put plants at risk due to seedbed variability not

completely removed by spring passes that are seen as

small wet/dry, cold/warm, high/low spots.

While trash whippers and other tooling certainly

help, avoid forcing your planter to double

unnecessarily as a seedbed preparation tool, too. Your

payoff for achieving a level, uniform output in both

fall and spring operations will be better germination

and stand uniformity, not to mention potentially

faster planter speeds.

To convert crop residue into soil-building humus,

soil microbes must decompose the residue. The

decomposition process requires the crop residue

to be incorporated into the top layer of soil, ground

moisture must be present, the soil must be warm and

the microbes must have a supply of oxygen. When any

of these elements are missing or are in short supply, the

decomposition process will not proceed properly.

Discing crop residue into the top few inches of the soil will

facilitate the decomposition process. Ample oxygen and

warmer soil temperatures near the soil surface promote

decay just as it will cause an untreated fence post to rot at

ground level.

Sunflower has a longstanding world-wide reputation

for building solid, reliable disc-based and sweepbased

tillage solutions. Some companies have moved

decidedly in the direction of low disc concavity in

favor of vertical tillage while somehow claiming

all the benefits of mixing. However, remember that

Sunflower tools not only manage compaction, but

also remain fully capable of achieving desired mixing

and incorporation levels regardless of your yields and

residue type.

Sunflower tools are designed to operate properly with

a wide “window” of capability between four-and-ahalf

and six-and-a-half miles an hour. All Sunflower

tools you use feature a wide range of built-in

adjustability, with top-notch dealer support to satisfy

you year-in, year-out. To sum up, choose the best

solution after combining your local experience with

the latest scientific discoveries—and a willingness to

modify your management while your seed choices

and other factors continue to change.
