Soil Preparation
* To build a uniform rm bed with no hollow spots, soil has to be
prepared properly.
* All soils are different. Some (moist, sandy) soils make nicer square
beds than others. You need to know what soil preparation works
best with your soil.
* Machine performs the best if soil is plowed 6” to 8” deep.
* Soil should be harrowed or roto-tilled until free of sod lumps.
* Proper moisture in soil is important to form nice rm beds. For
best results, soil should not be powder dry or in muddy condition.

Getting Started
Before laying plastic, you may want to try out the machine by making
beds only so you get the feel of the machine.
Adjust 3-point top link on tractor to level the machine.
Let the machine down fully and regulate the amount of soil in front of the
machine with the length of the 3-point top link.
It is not necessary to pull more soil than needed to ll the bed. Pulling too
much soil may cause tractor slippage, resulting in side drifting.
To get a higher, rmer bed, grower may want to pre-bed (make beds
without laying plastic) then come back to lay plastic mulch. This will also
help removing shallow spots in the bed. Disk blades can be removed
when making beds only.

Important: When bed height is adjusted, bed width (Page 7)

Bed height is adjusted by lifting and lowering the bed press. Use label
ruler behind pin indicator (top of pin) located on both sides of the ma-
chine to determine bed height(See Below).
To adjust bed height, release the lock handles. Raising the bed is done
by two people lifting the deck by hand, or by slowly driving forward
with the 3-point hitch in down position. The soil will lift the bed press.
To lower the bed, slowly lift 3-point hitch with the tractor to the de-
sired height and lock the handles.
If your bed is not rm and has shallow spots in the center, add weight
on the bed press, adjust the top link, and/or install the optional center
of bed llers.

Bed Width Adjustment
Adjustable Side Plates
Adjustment Slot
for Side Plates
The bed press has adjustable side plates (photo at bottom). These
must be adjusted according to bed height by releasing the bolt and
sliding the side plates in or out at the slot. Make sure bolts are
tight to keep them from slipping. For setting, follow chart on ma-
chine or on Page 6. It is important to maintain enough plastic at the
edge for proper coverage.
NOTE; For straight beds, each side must be equally adjusted.

To install plastic rolls, place them on top of rollers (A). Pull end of
plastic down in between rollers and underneath bottom roller (B). Secure
plastic and drip tape at end of row. Only feed from one roll at a time.
Plastic rolls have a tension brake. Just a slight tension is needed.
Note; Setting brake tension too tight may affect the performance of
the machine and can cause plastic to pull out from under press tires.

9
Press Wheel Adjustment
Press wheels need to run at the bottom of the trench and not
on the side to stretch the plastic properly. To adjust, loosen
T-handle and make in or out changes as needed.
Tilt the front of the press wheel on an inward angle to stretch
the plastic.
Use only high quality plastic to avoid straight line tear.

Trench Opener Adjustment
IMPORTANT!
Adjust machine so that 5” of plastic is covered on both sides

Trench openers are used to cut a trench along the sides of the bed.
This will give a ‘cup’ at the edge of the bed to prevent the plastic
from blowing off. If bed height is adjusted, the trench opener has to
be adjusted accordingly.

Cover Disk Adjustments
Cover disks and dirt shields are marked right and left side (stand-
ing in back). Install shields as marked, with snap pin towards the
center of the bed. Set disks on a 45 degree angle; make in or out
adjustment as needed. For more or less coverage, tilt disk forward
or backward as decal shows (pictured at bottom).
In some sandy soils the disk blades can be laid in a atter position
and turned at a 45 degree angle. However, if it does not cover the
plastic properly, the disks need to be set more upright or tilted back.

Side Shovel Adjustment
The side shovels are used to loosen more soil for the cover disks. Adjust
so that the shovel is approximately 1” to 2” below bed formers.
Adjust shovel shank in or out so they are in line with cover disks.

Ro-Trak Sensor
AUTO RO-TRAK
*Ro-trak has the most benets on hillsides and contours.
*Automatically steers to correct machine side drifting.
*Ro-trak is activated by a sensor at back of machine.
*Will keep the machine from “sh-tailing” on hillsides.
Helpful Tips
*When installing Hyd pump, lead hoses through 3-point A frame.
*Inspect and make sensor square to machine.
*Twelve-volts can be supplied by tractor or a separate battery.
*Ro-trak requires only low RPM pto speed to function.
*Hollow bed can effect Ro-trak performance.
*If machine has been setting for a period of time, it may be
necessary to manually move the valve spools to get oil through
the system.
*With PTO pump running, use a Phillips screw driver and push
the silver tip of the spool inward approximately ¼” (Page 14.)
*Manual Ro-Trak is operated with tractor hyd. and must be
steered by tractor operator.

Ro-Trak not functioning? Check for these problems.
1. Is the PTO engaged?
2. Is a 12 volt battery properly connected?
3. Is the sensor at rear of machine plugged in?
4. Check oil level.
5. Check for any damaged hoses or wires.
6. Is sensor lifted 3” or more? (Sensor has a transport cut off switch).
7. Do the indicator lights on solenoid light-up?
8. If indicator lights light-up and Ro-trak doesn’t function, push in
silver pins on solenoid spools (approximately ¼” on either side).
9. If indicator lights do not light up, undo plate on top of solenoid
and check for loose wires.
10. Steers only one way? Change bad steering switch in sensor.
11. Call Rain-Flo at [phone].

1. Periodically check oil level. Low oil level may cause air
to come into the system and effect Ro-Trak performance.
2. Change oil and lter every 200 hours or 3 years (ISO 46 Hyd. Oil).
3. Check for any damaged hoses or electric wires.

Drip Irrigation Roll Carrier
15
Slide drip roll onto roll carrier rod so
that drip emitter will be turned up toward
plastic (for less clogging).
Feed drip tape through the guide on
the swing arm and through the second
guide that’s bolted on the drip roll carrier
frame. (See sketch below.)
NOTICE:
Make sure
drip roll is
compressed rmly
between plates,
for positive braking effect.

Down Pipe
Feed drip line through the

into the drip line down pipe.
To avoid damaging drip tape
with the press pan, adjust bot-
tom of down pipe about 1” to
2” below the plastic mulch.
Turn drip emitters up toward
the plastic for less clogging.

CHANGING THE PLASTIC WIDTH
The Model 2570 will lay 3’ and 4’ wide plastic.
To make these adjustments, release the lock bolts at front end of bed shapers
(No.1) photo. Remove bolts at back end of bed shaper (No.2) photo and slide to
appropriate setting. Make sure bolts are tight.
Adjust bed press side plates; remove bolts from bed press side plates
and move to appropriate setting (No. 3) photo.
Adjust roll carrier; loosen bolts and slide bracket so plastic roll ts between
bracket (No.4) photo. Adjust approximate 1½” wider than plastic width.
