Soil Preparation
4
* 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 making beds
only; to get the feel of the machine.
Adjust 3-point top link on the 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 remove shallow spots in the bed. Disk blades can be removed when
making beds only.

4” ............20”
6” ............16”
8” ............12”
Bed Height Adjustment
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 machine 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 the down position; the soil will lift the bed press. To lower the bed,
slowly lift 3-Point hitch with the tractor to the desired 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.
Lock Handle Adjustment
Important: When bed height is adjusted, bed width (Page 7)
and trench openers (Page 10) need to be adjusted accordingly.

Bed Height Indicator
Bed height and bed width can be adjusted between the above chart indications.

Bed Width Adjustment
Adjustable 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 machine 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.

Plastic Tension
Plastic rolls have a tension brake. Just a slight tension is needed.
Tension
Brake
Adjustment
Note; Setting brake tension too tight may affect the performance of
the machine and can cause plastic to pull out from under press tires.
Installing Plastic Rolls
To install plastic rolls, place them on top of rollers (A). Pull end of plas-
tic 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.

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 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

Depth
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 the back of machine.
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 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].
Hyd. Oil Level
Solenoid Valve
Auto Ro-Trak
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
Drip Irr. Tape Placement
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 rst guide
on the swing arm and through the second
guide that’s bolted on the drip roll carrier
frame. (See Sketch Below.)
NOTE;
Make sure
drip roll is
compressed rmly
between plates
for positive braking effect.
Feed drip line through the
guides on the spool carrier and
into the drip line down pipe.
To avoid damaging drip tape
with the press pan, adjust top
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 2670 will lay 3’, 4’, or 5’ 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 former (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.
