SECTION C—Weed Zapper Attachment Procedures

Requirements for Attaching the Weed Zapper to the Tractor

• The front mount applicator boom requires three separate hydraulic feeds. These supply the three
  working points on the tractor. The Weed Zapper is designed to be attached to the tractor with two 3-
  Point units or lifting apparatus, one on rear and one on front of tractor. Both the front 3-Point unit as
  well as all hydraulic hose assemblies needed are available through OSM. Please contact your dealer
  or OSM direct for pricing. Information is also available on our website http://theweedzapper.com
• The operator is responsible for providing two 3-Point hitch units or lifting apparatus (loader or
  stationary loader 2-Point) on the tractor and all hosing required to operate the applicator boom.
• The HV transfer cable, provided by OSM, which carries the electrical charge from the cart to the
  applicator boom must be safely routed and installed by the operator. Operator can attach the front-
  mount applicator boom to a 3-Point hitch or a loader attachment.
• Stationary lower two-point arms are an option. Operator would need to attach stationary lower two-
  point arms by using a secondary lifting device such as another tractor loader or similar unit if this
  option is chosen.
• Old School Mfg. LLC offers a light-duty 3-Point hydraulic hitch unit (see Page C-2) capable of carrying
  and operating the applicator boom. These 3-Point units are available as a special order and priced very
  competitively. Please refer to the website at http://theweedzapper.com

Mounting Applicator Boom to Front of Tractor
Watch video at following link- https://youtu.be/BrAjyQqcwI4?list=PLyk7xDwLud2W5ENu0G3Q53g1enk-PSxNV

1. To prevent serious injury or death, check to ensure the hydraulic transport lock on the unit is in the closed
   position, to lock the applicator boom wings in the upright position.
2. Align the tractor with the applicator boom and pull forward.
3. The lower lift arms should contact the lower lifting pins on the applicator boom.
4. Stop tractor engine, set park brake and remove key.
5. Install pins and corresponding keepers.
6. Install hydraulic top link cylinder.
7. Use the tractor to lift applicator boom a few inches.
8. Stop tractor engine, set park brake and remove key.
9. Fold up the four stands and lock them in place with supplied pins. Keep your hands clear to avoid pinching.
10. Walk all the way around The Weed Zapper to ensure that all pins are in place and all lift pins are securely fastened.

Attaching Cart to Rear of Tractor Utilizing a 3-Point Quick Hitch Apparatus

1. Align tractor with cart and back into place.
2. Lift the quick hitch to engage the pins on the carts 3-point mount.
3. Stop tractor engine, set park brake, and remove key.
4. Release the quick hitch latches locking it to the pins.
5. Adjust the attachment unit on the tractor to make sure the pins on The Weed Zapper are engaged
   correctly.
6. Connect the PTO shaft to the tractor.
7. CAUTION: Do not lower unit too far causing the frame to contact and bend the PTO Shaft.

Setup of Applicator Boom for Field Operation Mode (see photo above)

1. Open applicator boom wing hydraulic transport lock valve (see Page C-2), start tractor engine and
   hydraulically lower wings into field operation mode. CAUTION: Stay clear when lowering boom
   applicator wings.
2. Stop tractor engine, set park brake and remove key.
3. Manually place the applicator boom wing stops in field operation position before beginning use of
   machine in field. Place wing-stop lock pin in storage hole (see Pages C-3 – C-4).

Moving Trailer Tow Wheels or Stationery Stands into Field Operation Mode (see Page C-5)

1. After cart is hitched to the tractor, set the park brake, stop the tractor engine and remove key.
2. With cart lifted off ground, remove keeper in pin next to wheel and tire. This does not apply if your
   cart is equipped with pins with detent ball.
3. Pick up on wheel or drop-down stand to release pressure on pin.
4. Remove the pin and firmly pull the wheel forward.
5. Replace the pin in the lower pin-hole position.
6. Replace the keeper (if applicable). Repeat steps for the other wheel and tire.
   If your unit is a newer model, it should be equipped with beveled, spring-loaded pins referred to as “slam
   pins”. If so, once the lock pin is removed, forcefully slam the axle forward and upward causing it to
   engage the slam-lock pin and lock it into the up position. Then place the lock pin back in the pin-hole
   position

Disclaimer: Although unit is shown in this photo as a rear-mounted applicator boom, it
should be noted that The Weed Zapper is designed to be used in a front-mounted
application. Using the applicator boom in a rear-mounted application for an extended period
of time (more than 10 hours annually – exception is model 6R30) may result in metal fatigue
and lead to frame failure. The rear-mount option should only be used on a short-term basis.

Mounting Applicator Boom to Rear of Cart for Temporary Field Operation Mode

1. Make sure applicator boom is in Park Mode with parking stands down on a firm surface
   and pinned in place. Also, the applicator boom wings should be locked in the upright
   position with the hydraulic transport lock on the unit in the closed position.
2. With cart attached to rear of tractor (See Hitching Tractor to a Three-Point Cart
   procedure) and jack stand up and locked in place. Fold the trailer tow wheels up and
   lock into place. (See the Moving the Trailer Tow Tires into Field Operating Position
   procedure). Align and back up to the applicator boom.
3. The lower lift arms, on the rear of cart, should make contact with the bottom pins of the
   applicator boom.
4. Stop tractor engine, set park brake and remove key.
5. Install pins, corresponding keepers and attach top-link hydraulic cylinder.
6. Use the tractor to lift cart and applicator boom a few inches.
7. Stop tractor engine, set park brake and remove key.
8. Fold the four parking stands up and pin in place. Keeps hands clear

Adjusting Coulters for Opposite Travel Direction
To move a front-mounted applicator boom to the rear for temporary operation, or to move a
temporary rear-mounted applicator boom to the front for operation, the coulter travel direction
will need to be reversed.

1. Lift applicator boom wings off ground and place supports under them.
2. Stop tractor engine, set park brake and remove key.
3. Unplug pertinent wiring harnesses and plugs.
4. Loosen the four nuts that attach each coulter shank to the applicator boom. Take steps
   to ensure that coulter and shank do not fall when nuts are loosened. (NOTE: Some
   units are made with double counter sinks drilled into coulter shank. In this case,
   simply loosen coulter locking ring bolt and rotate coulter 180 degrees.)
5. Rotate coulter shank assembly 180 degrees.
6. Tighten the four nuts to the appropriate torque of 60 foot-pounds (81 joules).
7. Re-attach all pertinent wiring harnesses and plugs

Row Spacing Adjustment for Coulters

1. Make sure applicator boom is in Park Mode with parking stands down on a firm surface
   and pinned in place. The hydraulic transport lock on the unit should also be in the
   closed position with the applicator boom wings lowered into the field operation position.
2. Loosen the four nuts that attach each coulter shank to the applicator boom. Take steps
   to ensure that coulter and shank do not fall when nuts are loosened.
3. Determine row spacing. (NOTE: Coulters may be adjusted for different row widths.)
4. Slide coulters to desired width positions.
5. Tighten the four nuts to the appropriate torque 60 foot-pounds (81 joules).
