Question 1

Will the Devastator fit a chopping head?

Accepted Answer

Yes, the Stalk Devastator fits most corn head models, including 20-inch, 22-inch, and chopping heads.

Question 2

How should I space my Twister Closing Wheels?

Accepted Answer

As a general starting point, we recommend spacing your Twister Closing Wheels at 1.25 inches. Then evaluate your field conditions, soil type, and tillage practices to make any necessary adjustments.

Question 3

My seed jet engine will not start. What should I do?

Accepted Answer

Most likely the engine oil level is too low. Check the engine oil level and add oil as necessary. The oil level must be on the full mark to engage the oil level sensor.

Question 4

What type of oil do I put in the seed jet blower?

Accepted Answer

Use gear oil ISO 220, or an equivalent.

Question 5

How much pressure should I be using to inject liquid fertilizer?

Accepted Answer

Use less than 30 PSI to reduce the amount of splattering.

Question 6

How deep should I set the spring-loaded injection rod on my fertilizer coulter?

Accepted Answer

Set the rod to operate at 0.5 inches below the soil surface.

Question 7

My row unit will not penetrate soil for an even seeding depth. What should I do?

Accepted Answer

Increase down pressure on the row unit
Check planter frame height
Add ballast to the planter frame
Adjust no-till coulter to penetrate less than seed depth

Question 8

Why are my residue manager wheels running deep in conventional tillage conditions?

Accepted Answer

Planter is not level—raise the planter drawbar
Too much row unit down pressure
Frame height is too low—refer to planter operator’s manual
Soil is very loose

Question 9

How do I know where to set the row cleaners?

Accepted Answer

Residue is hairpinning—too shallow
Soil is being moved—too deep
You see a wheel slow down once in a while—set about right

Question 10

Do I take the seal out of the residue manager hub assembly, or do I leave it in?

Accepted Answer

Yes, you can do whichever best fits your operation. If you take the seal out, grease every 50 hours. If you leave the seal intact, fill the wheel assembly with grease before using. No need to grease again until you replace the bearing.

Question 11

Which holes on the adjustment stem do I mount the residue manager wheels in?

Accepted Answer

In most conditions, mount the wheels offset in the front hole and rear hole. In some cases, they may perform best when mounted in one front hole and one middle hole.

Question 12

How do I properly set up the fertilizer coulter with a rear knife?

Accepted Answer

Center the blade on the hub so it rotates concentrically. Align the knife tip to lightly contact the coulter blade, then ensure a gradual gap as the blade rotates. The knife should also be centered side-to-side.

Question 13

My fertilizer coulters are plugged with residue, even though I have them adjusted properly. How can I prevent this?

Accepted Answer

In some conditions, a knife scraper is needed to keep residue from dragging up on the fertilizer knife.

Question 14

What can I do to speed up my markers?

Accepted Answer

Tri-fold markers include restricted elbow fittings to prevent rapid operation. If slower than 8 seconds, drill the restriction with a 1/16-inch bit. Adjust oil flow so operation is no faster than 8 seconds.

Question 15

How much tension should I run on my spiked closing wheels?

Accepted Answer

Usually zero tension or first notch
Adverse conditions may require more tension
Full length of the spike should be in the soil

Question 16

How can I improve seed germination?

Accepted Answer

Poor seed germination may be caused by seed being too close to residue (e.g., corn-on-corn), which can cause allelopathic poisoning. Use a residue clearing device to improve germination.

Question 17

How can I improve seed-to-soil contact?

Accepted Answer

Adjust coulter height properly, ensure planter hitch is at correct height, replace worn double disc openers, and avoid planting in wet soil.

Question 18

How do I know when I have too much row unit down pressure?

Accepted Answer

Gauge wheels are picking up soil
Planter frame height is too high
Seed trench is compacted
Residue managers operating too deep
Excessive wear on gauge wheel tires and disc opener blades

Question 19

Why does the planter have to be level for the Yetter attachments to work properly?

Accepted Answer

We design our products to operate on a level planter. Unless the planter is level, the attachments will not perform successfully.

Question 20

How fast should I be planting?

Accepted Answer

You should be planting at 5–5.5 mph. Speed affects seed spacing and depth unless you have a high-speed planter.
