Mounting bolts and hardware

Before operating the 2961 CUT-N-FEED for the first time, check to be sure that all
hardware is tight. Check all hardware again after approximately 50 hours of operation
and at the beginning of each planting season.

All hardware used on the 2961 CUT-N-FEED is Grade 5 unless otherwise noted. Grade
5 cap screws are marked with three radial lines on the head. If hardware must be
replaced, be sure to replace it with hardware of equal size, strength and thread type.
Refer to the torque values chart when tightening hardware.

Important: Over tightening hardware can cause as much damage as when
under tightening. Tightening hardware beyond the recommended range can
reduce its shock load capacity.

The chart below is a guide for proper torque. Use it unless a specified torque is called out
elsewhere in the manual.
Torque is the force you apply to the wrench handle or the cheater bar, times the length of the
handle or bar.
Use a torque wrench whenever possible.

The following table shows torque in ft. lbs. for coarse thread hardware.

Lubricate all bearings and moving parts as assembled and make certain that they work freely.

WARNING: Never work around the toolbar/implement while in a raised position without using
safety lockups.

CAUTION: The
while handling and or maneuvering the opener during assembly. Failure to do so may lead to
personal injury.

2961 CUT-N-FEED is very heavy. Pay extra attention to lifting techniques

OPERATION PRECAUTIONS

STOP

Read this before using the Yetter product.

- MACHINE OPERATION

IMPORTANT: failure to properly set the planter frame height and
levelness can result in less than successful operation of the planter
and the Yetter product and may result in damaged equipment.
operators should read and thoroughly understand the instructions
given prior to using the Yetter product.

NOTE: DO NOT use this product if the planter is not adjusted properly!

Leveling the planter:
With the planter lowered to proper operating height (Usually 20”-22”).
Read the planter operator’s manual for recommended setting. Check to
be sure the toolbar and row unit parallel arms are level fore and aft. Re-
check when the planter is in the field and has been fully loaded with seed,
fertilizer, granular chemicals, etc. Also, a field check with a bubble level on
the frame should be made of the hitch height to ensure level operation front
to back.

It is important for the planter to operate level laterally. Tire pressure must be
maintained at pressures specified by the manufacturer.

Field and actual planting conditions change and will dictate planter frame
heights. You must ensure that the row unit parallel arms are approximately
parallel with the ground.

IMPORTANT: For proper operation of the planter attachments and row
units, it is imperative that the planter toolbars and row unit parallel arms be
level side-to-side and front-to-rear. The toolbar frame should operate at a
20”-22” height from the planting surface
operator’s manual for instructions on how to adjust the frame height and
levelness.

LIQUID FERTILIZER APPLICATION RATE AND PRESSURE CHART

TABLES ARE BASED ON 30” NOZZLE SPACING

Values in this chart area based on using water. To calculate nozzle size required for your fertilizer application, the weight of the
fertilizer solution must be accounted for by using a conversion factor for specific gravity. The Conversion factor for 28% liquid nitrogen
is 1.13. Example: desired rate of application is 10 GPA of 28% N multiply 10 gallons per acre of fertilizer you want to apply x the
conversion factor for 28% N (1.13) to get an equivalent rate for water. 10 x 1.13 refers to the chart for 11.13 gallons per acre at your
desired speed/MPH.

GPA = 5940 X GPM H20 = WATER SOLUTION FACTOR
(Per Nozzle) MPH X W GPA = GALLON PER ACRE 28% = H20/1.13

GPM = GALLON PER MINUTES 32% = H20/1.15

MPH = MILES PER HOUR

W = WIDTH

This table is a reference only. Please calibrate your equipment to insure proper rate of application.
The information contained in this issue is offered in good faith by Yetter Mfg. Co. to further the understanding of liquid fertilizer
application.

However, the use of the information provided is beyond the control of Yetter Mfg. Co. and in no case shall Yetter Mfg. Co. or any seller
of its products be responsible for any damages that may occur from the use of this information.

Our name

Is getting known

Just a few years ago, Yetter products were sold primarily to the
Midwest only. Then we embarked on a program of expansion and
moved into the East, the South, the West and now north into Canada.
We’re even getting orders from as far away as Australia and Africa.

So, when you buy Yetter products . . .you’re buying a name that’s
recognized. A name that’s known and respected. A name that’s
become a part of American agriculture and has become synonymous
with quality and satisfaction in the field of conservation tillage.

Thank you.
