!! Safety First !! Read and understand all caution labels on the machine. No riders beyond the speed of 3 MPH. Double check that everyone is clear before lowering the machine. Use caution when turning around; machine is 9’ long. Do not crawl under the machine when lifted.

Getting Started 1. Adjust 3-point top link to level machine. 2. Load plastic roll into bottom roll cradle and spare roll into top cradle. 3. Feed plastic through rollers (page 8). 4. Load driptape roll(s) onto carrier and feed through guides (page 9). 5.
Bed Height & Width Adjustment Bed height and width is adjusted with four hand pins located on each side of the bed press (See below). To change from the 8” setting (pictured below) to a 4” setting use the steps below. 1.
Compression Rate Adjustment Compression rate or angle of the bed press regulates the amount of soil between the moldboards. It is adjusted using the turnbuckle on the left (see below). If you have insufficient soil or a hollow bed use less compression by lowering the front of the bed press.
Installing Plastic Rolls To install plastic rolls, place feed roll on top of rollers (A) and spare roll on rollers (D). Pull end of plastic down between rollers and in front of 2” roller (B). Next feed it between the 4” green and 3” silver rollers (C). See illustration below.
Installing Drip Tape Roll 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 first guide on the swing arm and through the second guide that’s bolted on the drip roll carrier frame.
Press Wheel Adjustment Press wheels need to run at the bottom of the trench and not on the side to stretch the plastic properly. Adjust the position of the press wheel using pin (A). After bed height/width is changed press wheels need to be adjusted according.
Trench Opener Adjustment Trench openers cut a trench along the sides of the bed. This allows plastic edges to form a ‘cup’ when covered with soil and prevents the plastic from being lifted from wind. Depth Trench Depth Adjustment Openers Adjustment IMPORTANT! Adjust machine so that 5”...
Cover Disk Adjustments Cover disks and dirt shields are marked right and left side (standing in back). Install shields as marked and shown below. Use inside turnbuckles to set disks on a 45 degree angle. Make left / right adjustment as needed using the outside turnbuckles. For more or less coverage, tilt disk forward or backward as decal shows (pictured at bottom).
Optional Hyd. Disk Adjustment There’s a hydraulic kit available for the cover disks that is useful for fields that have varying soil types and conditions. Adjustments can be made from the seat while on the go. Front Disk Adjustment Front disks help fill the bed and loosen more soil for the cover disks.
AUTO RO-TRAK *Ro-trak has the most benefits on hillsides and contours. *Automatically steers to correct machine side drifting. *Ro-trak is activated by a sensor at back of machine. Helpful Tips *When installing Hyd pump, lead hoses through 3-point A frame. *Inspect and make sensor square to machine.
Auto Ro-Trak Maintenance 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 filter every 200 hours or 3 years (ISO 46 Hyd. Oil). 3. Check for any damaged hoses or electric wires. Ro-Trak not functioning? Check for these problems.
Plastic Mulch Cutter The plastic mulch cutter enables the machine operator to cut the plastic film from the seat. At the end of the row raise machine approximately 12” off the ground and pull handle to lower the cutter. Drive tractor forward several feet and plastic mulch will tear off.
* A sizable tractor is needed for stability and lifting power. Minimum tractor size for Model 480 is approximately 80 HP. * This machine can also be used for a bedder only, (without laying plastic). The rear cover disks and tires can be removed for this application.
TROUBLESHOOTING PROBLEM Machine tends to drift sideways causing disks to cut into plastic mulch. SOLUTION * Pull less soil. Pull just enough to fill a firm bed. * Adjust 3-point top link and/or compression rate (page 7). * If your machine has Manual Ro-Trak, make sure the sway bar is in place and machine centered.
