Manual-Control Models
On the manual-control system, spinner speed adjustments
are made on the valve located on the right side of the Turf
Tender. The speed of the spinners is not to be adjusted while
the Turf Tender is running. The scale on the speed control
valve is not calibrated to represent any particular units, however
much like the electric-control model, the scale is fairly linear.
Upon completing an adjustment on models using a diverter
valve, secure the adjustment by tightening the thumb screw
securely. To adjust the spinner speed on your manual-control
system, use the following procedure:
1. Operator sets parking brake.
2. Operator shuts off engine.
3. Operator dismounts and adjusts flow.
4. Operator returns to tractor and starts engine.
5. Operator tests Turf Tender using new setting.
6. Operator repeats process as often as necessary to get correct
flow and correct speed.
SPINNER ASSEMBLY
Installation And Use
The spinner shafts are made of stainless steel to reduce the
chance of corrosion. Applying Anti-Seize (a special type of
grease) is recommended to facilitate greater corrosion resistance.
Each time a spinner is removed or installed, apply Anti-Seize
to the entire spinner shaft.
Each spinner is secured by a swift detach button (just like a
power take off (PTO) shaft), so it can be removed and installed
quickly. To remove and install a spinner, support the spinner;
then press inward on the button to release the spinner from
the shaft. Slide the spinner off the shaft. Apply Anti-Seize to
the shaft; then slide the spinner onto the shaft. Press the button
inward and continue to slide the spinner onto the shaft until
the button pops back to the lock position. Make sure the button
pops completely out to lock the spinner on the shaft. Push and
pull the spinner up and down on the shaft to make sure it is
secure.
CAUTION
Use care and firmly support the spinner when
removing and installing. Also, be sure the spinner
is firmly locked on the shaft.
Adjustments
OVERVIEW
A variety of materials from sand and larger aggregates down
to grass seed and fertilizer can be spread with Turf Tenders.
All Turf Tenders use the same spinner disk assemblies. The
410 Turf Tender models use smaller hydraulic motors and is
designed for light and heavy topdressing, seeding, and fertilizer
applications. All other Turf Tender models are designed for
light to heavy application rates and use larger hydraulic motors.
Coverage can be as wide as 50 feet (15 m). It should be noted
that “fine tuning” the system for the specific material being
spread is essential. The information presented here represents
thousands of hours of design and testing, as well as feedback
from people like you, the users of our products. Please read
this information thoroughly to ensure that you have an
understanding of it’s content.
Different materials require different spread patterns.
DAKOTA
offers three (3) different colored spinners so you
can have multiple sets with each set adjusted for a specific
material. All sets have black blades. Suggested uses of the
different colored disks are:
1. White spinner disks for sand (included with the Turf
Tender).
2. Black spinner disks for spreading fertilizer.
3. Green spinners disks for grass seed.
The stock set could be used for all materials if you take the
time to adjust them for each material. Contact a DAKOTA
dealer for additional spinner disks.
BLADE ADJUSTMENTS
The following figure shows a white right-side spinner disk
with black blades as assembled at the factory. Different
application rates and types of material may warrant changing
the blades from their “neutral” position. Also, gate opening,
spinner speed, and conveyor speed will affect the pattern. In
general for best application of material,
avoid running the
conveyor too slowly and avoid running the spinners too
fast.
The factory “neutral” setting was designed to yield the
best spread pattern under the following conditions:
Material: moist sand (barely clumps when hand squeezed)
Gate Opening: 3/4 in. (from the flat of the belt)
Conveyor Speed: 70 RPM (about 70% dial setting)
Spinner Speed: 350 RPM (about 65% dial setting)
