INTRODUCTION
The 2984 Maverick Opener Unit has been specifically designed for strip-till and those users who demand
the utmost in accuracy of fertilizer placement along with the durability and capability to perform at least one
other operation in the field simultaneously.
The Maverick Opener is a combination of existing and new technologies. The unit is based on our
patented parallel arms and attaches to a toolbar with a rugged clamp bracket casting. The main frames are
heavy twin 5/8” x 5” plates , which includes punched holes, for mounting of various attachments. The
formed knife plates are attached by 5/8” grade 5 bolts. The fertilizer knife is attached to the lower part of
the knife plate using grade 8 bolts. The upper rear part of the knife plate has provisions for attachment of
either a disc sealer or a wheel sealer with 4.5 x 16 gauge wheel tires.
This is a very versatile unit that may be complemented by other Yetter attachments, such as the 2984-004
depth control and 2984-003 residue manager.
OPERATION
The Maverick Opener is a universal tool designed for use in any fertilizer management program. The
Maverick Opener is the ultimate unit when properly equipped for; Fall strip tillage, Spring pre-plant,
Summer side-dressing and Fumigation.
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.
It is important to remember that the Maverick Opener unit is similar to a 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 an influence on performance. If damp
soil is building up on the wheels, discs or knives then it is less than optimum conditions to operate, thus the
Maverick Opener will not work at it’s best.
CAUTION Frozen soil or heavy rock population may cause damage to the Maverick Opener .
Note: In soil where rocks are present, it is recommended to use a 22” diameter blade(2571-196).
