OPERATION
YETTER model 2984 Maverick Opener is a multi-functional tool designed for use in a fertilizer
management system. The Maverick Opener fully equipped, is capable of residue management, precision
fertilizer placement, soil tilth and soil berm/mound building all in one pass. Thus creating a seedbed that
will increase your Return On Investment.
It is important to know that the Maverick Opener unit is similar to a row crop planter unit in operation, thus
it is very important to adjust the frame height and levelness for best performance. Soil conditions (i.e.;
frozen soil, rocks, heavy, tough residue) have a major influence on the performance of the Maverick
Opener . If damp soil is building up on the wheels, discs or knives then conditions are less than ideal and
the Maverick Opener will not perform at its best.
The unit when equipped with sealing wheels is ideal for controlling soil disturbance and leaving a level soil
surface with the fertilizer sealed in. The unit equipped with sealing discs may be set up to close the knife
slot with the blades pushing or with the blades turned to pull, form a mound or “berm” of soil over the knife
slot to seal in the fertilizer.
CAUTION Frozen soil or heavy rock population may cause damage to the Maverick
Opener .
IMPORTANT: For proper operation, the toolbar frame must operate level (for, aft and
side to side) and at the correct height, typically 24”.
In hard or rocky soil conditions, the desired operating depth of the knife may not be possible. Increase the
spring pressure to obtain the desired depth rather than lower the toolbar frame below the 24” recommended
setting. Toolbar weight may limit operating depth in hard soil conditions, add ballast to the toolbar frame.
Example 200#’s per opener have been added to the frame to achieve the desired depth. Operating depth
of the Maverick Opener is affected by spring tension, toolbar height, levelness of toolbar and soil tilth.
As soil conditions change, toolbar settings and coulter adjustments will need to be changed as well.
Toolbar gauge wheel kits are optional but advocated for use with the Maverick Opener because of
toolbar frame height being critical for proper operation, 24”.
1. Set/mount coulter blades to run perpendicular to the soil. Operation depth and blade wear can be
affected if the coulter mounted crooked or if the toolbar is not level side to side.
2. After a few hours of use, check all bolts for tightness and proper torque.
3. After a day of use (10-12 hours) check coulter hubs for loose bearings. There should be no
endplay in the hub bearings allowing the blade to wobble. If necessary, remove cotter pin and
adjust the slotted nut to remove wobble, recommended torque of 13 ft. lbs. and re-insert cotter pin.
If the wobble or looseness cannot be corrected, the bearings, cups and seals will need to be
replaced. DO NOT REUSE WORN OR DAMAGED PARTS.
