OPERATION PRECAUTIONS
To ensure the hydraulic compresso
r motor doesn’t exceed the recommended operating RPM level, the hydraulic oil flow control valve
has been preset. In some instances, the compressor may run below optimum rpm, or will not reach 145psi of tank pressure read at
the gauge on the compressor unit. If this is the case, an adjustment to the flow control valve will need made. Only open the flow
control valve enough to allow the compressor to build to 145psi tank pressure read at the gauge on the compressor unit. Opening the
flow control too far could cause over speeding and reduced service life of the compressor. Follow the instructions below to make the
proper adjustment.
NOTE: Before making any adjustments to the flow control valve, adjust the tractor hydraulic flow fully open. Adjusting the
tra
ctor’s hydraulic flow will affect the compressor’s RPM. The hydraulic motor speed on the hydraulic compressor should not
exceed 1350RPM. RPM
’s on the hydraulic compressor may be checked via the fan blades with an optical tachometer.
STEP 1: Remove the black seal from hydraulic flow control valve and jam nut (2018 and newer will not have seal).
STEP 2: Flip the switch to ON on the 2984 Strip Freshener control box & supply hydraulic pressure to the compressor.
Make adjustments while hydraulic motor is running. Open tank drain to allow continuous running if necessary.
STEP 3: Insert an Allen wrench into flow control valve. 2013 - 05/2018 models use a 5/16, 06/2018
– present use a 3/16.
STEP 4: Loosen jam nut by turning counterclockwise. 2013 - 05/2018 models use a 11/16, 06/2018
– present use a 1/2.
STEP 5: Using the Allen wrench, SLIGHTLY turn the flow control valve counterclockwise (the equivalent to 3 degrees or
1/32 of a turn) to increase the hydraulic motor speed.
STEP 6: Hold the Allen wrench in place and tighten the jam nut. Each time an adjustment is made, allow the compressor to build to its
potential 145psi shut off mark. If 145psi is not achieved, drain tank pressure until compressor turns on, and make another
adjustment. Repeat these steps until 145psi is achieved so that the compressor runs smoothly without struggle. DO NOT RUN
MOTOR ON COMPRESSOR MORE THAN 1350RPM! RPMs can be checked with an optical tachometer using the fan blades.
Once the flow control valve is set properly, hold the Allen wrench in place and tighten the jam nut.
OPERATION
The Tank Pressure should always be above 100psi. If using Yetter Electric/Hydraulic Compressor units, each compressor will shut
off at 145psi & engage to recover back to 145psi when tank pressure drops to 120psi. Make sure to have all circuits set at 0psi
when setting the toolbar & units for optimum performance begins.
Follow these steps to set the strip freshener CC units to achieve the best results:
Step 1: Set the depth (approximate) on each row unit. Adjust screw adjust knob (15/16 wrench) to achieve your preferred depth.
Adjustments can be made in ¼” increments. Rotating the screw adjust knob clockwise will raise the gauge wheels making
the units go deeper. Rotating the screw adjust knob counterclockwise will lower the gauge wheels making the units go.
shallower The depth decal on the side of each unit is only a reference & NOT an actual depth in inches as to where the unit
is set. For example, 3 does not mean 3 inches deep necessarily. Actual depth is determined by how low the cutting coulter
is below the gauge wheels. Other factors can play in to setting the depth such as row cleaner and rolling basket settings.
Step 2:
Apply row unit down force until each unit’s ride is consistent, smooth, & the correct depth is achieved.
Row unit downforce
should never be above 100psi. Row unit down force may need re-adjusted once the row cleaner is set properly in step 3.
Step 3: Fine tune the row cleaners by applying up or down pressure. The row cleaners should only be cleaning residue from the
strip & not engaging the soil.
Step 4: Apply pressure to the rolling basket cylinder to condition the strip & incorporate fertilizer if applicable. Row unit downforce
may need re-adjusted once the rolling basket is set properly.
Step 5: Recheck the depth of each row unit & adjust as needed. (SEE STEP 1) Check the depth on each row by removing the
loose soil until the bottom of each strip is found. For most accurate measurement, remove the residue away from the top of
the soil surface next to each strip where measuring & measure from the bottom of each strip to the top of the soil surface.
