Important Safety Information

Look for Safety Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that follows it. In addition to design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Prepare for Emergencies

 Be prepared if a fire starts

 Keep a first aid kit and fire extinguisher handy.

 Keep emergency numbers for doctor, ambulance, hospital

and fire department near phone.

Be Familiar with Safety Decals

 Read and understand “Safety Decals” in Operator

manual.

 Read all instructions noted on the decals.

 Keep decals clean. Replace damaged, faded and illegible

decals.

CTA4500 & CTA4500HD Table of Contents Important Safety Information 2

Avoid High Pressure Fluids

Escaping fluid under pressure can penetrate the skin, causing serious injury.

 Avoid the hazard by relieving pressure before

disconnecting hydraulic lines.

 Use a piece of paper or cardboard, NOT BODY PARTS, to

check for suspected leaks.

 Wear protective gloves and safety glasses or goggles when

working with hydraulic systems.

 If an accident occurs, seek immediate medical assistance

from a physician familiar with this type of injury.

Maximum transport speed for air drill is 20 mph (32 kph). Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

 Do not exceed 20 mph (32 km/h). Never travel at a speed

which does not allow adequate control of steering and stopping. Reduce speed if towed load is not equipped with brakes.

 Comply with state and local laws.

 Do not tow an air drill unless the towing vehicle is rated

for, and ballasted for, the weight of the air drill.

 Carry reflectors or flags to mark air drill in case of

breakdown on the road.

 Do not fold or unfold the air drill while the tractor is

moving.

Practice Safe Maintenance

 Understand procedure before doing work. Use proper

tools and equipment. Refer to this manual for additional information.

 Work in a clean, dry area.

 Lower the air drill, put tractor in park, turn off engine,

and remove key before performing maintenance.

 Make sure all system pressure is relieved.

 Inspect all parts. Make sure parts are in good condition

and installed properly.

Setup

This section covers mating the implement to a compatible air cart, and final setup items on the implement.

Some of these items are repeated in the cart and implement Operator’s Manuals. The Operator’s Manuals may also have additional setup items that may be appropriate to accomplish prior to delivery (such as installing the seed monitor in the tractor, if the tractor is available).

Hitching

When transported by the customer, the air drill is part of a train that includes the tractor and the assembly (the cart and the air drill).

When hitching for pre-delivery setup, hitch the leading cart to the tractor first.

Once the cart is hitched to the air drill, it is usually left connected, unless parking or storage considerations require separation.

This manual includes full details only for the air drill’s hitch. Consult the cart manual for cart-to-tractor hitching.

Equipment Damage Risk:

If the tractor has a load-sensing or constant-flow hydraulic system, the air drill must be equipped with an optional bypass valve to avoid tractor damage. See the CTA4500 & CTA4500HD Operator’s Manual for ordering and setup information for the bypass kit.

Crushing Hazard:

You may be severely injured or killed by being crushed between the tractor, cart and air drill. Do not stand or place any part of your body between machines being hitched. Stop tractor engine and set park brake before installing hitch pins.

Only trained personnel should work on system hydraulics!

Escaping fluid under pressure can have sufficient pressure to penetrate the skin, causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical attention from a physician familiar with this type of injury.

The standard air drill has one hydraulic circuit (with a low pressure relief valve return line). The standard circuit powers lift, fold and weight-transfer functions, controlled by a valve block on the right front of the air drill.

Raise/Fold Hose

This hose is connected to valve block port “V3” on the implement. Connect it to port “C” on the cart.

Lower/Unfold Hose

This hose is connected to valve block port “V4” on the implement. Connect it to port “D” on the cart.

Relief Valve Return

This hose is connected to valve block port “DUMP” on the implement. Connect it to port “G” on the cart.

Check hose routing to ensure adequate slack for link arm movement, and clearance from pinching or abrading cart/air drill components.

Equipment Damage Risk:

If the tractor to be used has a load-sensing or constant-flow hydraulic system, the drill must be equipped with an optional bypass valve to avoid tractor damage. See Options section of Operator manual for ordering.

Equipment Damage Risk:

DO NOT connect the Sump return line to a tractor power-beyond-port.

Bleeding Hydraulics

To function properly, the hydraulics must be free of air. If hydraulics have not been bled, they will operate with jerky, uneven motions and could cause wings to drop rapidly during folding or unfolding. During initial implement setup complete the following procedures.

Escaping fluid under pressure can penetrate skin, causing serious injury. Avoid the hazard by relieving pressure before disconnecting or “cracking” hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical attention from a physician familiar with this type of injury.

Bleed only at a JIC (Joint Industry Conference, 37 flare) or NPT (National Pipe Thread, tapered thread) fittings, and never at ORB (O-Ring Boss) fittings.

Bleeding Lift Hydraulics

1. Check hydraulic fluid level in tractor reservoir and fill to proper level. Filling a completely empty lift cylinder set requires about 2 gallons of oil.

Refer to Figure 13

2. Manual Valve: Set both valve levers to the Field position.

 Although the fold cylinder valve handle is set to

FIELD, fold cylinders may still be activated by the Weight Transfer circuit.

Refer to Figure 14

3. Electric Valve: Press the frame control softkey

to activate the fold/unfold button. When the fold/unfold button is highlighted, the tractor remote lever can be used to fold and unfold the machine.

 Fold implement only if fold hydraulics are bled free of

air and fully charged with hydraulic oil.

 Keep away and keep others away when folding or

unfolding implement.

Before folding, you must hitch the implement to the tractor and cart. Failure to do so could result in severe equipment damage and bodily injury or death.

1. Check hydraulic-fluid level in tractor reservoir and fill to proper level. Filling a completely empty fold cylinder set requires about 5 gallons of oil.

Primary Seed Hose Routing

Refer to Figure 32, Figure 33 and Figure 34

Hoses will be connected at the tower end, routed to the meter box, and cut to length.

Review and plan each hose route.

Connect each tower to its corresponding outlet on the cart’s rear meter box.

Start with tower 3.

1. Mark the expected cut location on the hose, but do not cut it prior to routing.

2. Route hose over implement frame. Run hoses for wing towers through hose holders shown.

3. Slide band clamp over implement end of hose, then slide hose at least two inches onto tower inlet. Allow enough hose slack so that implement raising, lowering, folding and unfolding will not pinch or bind hose.

4. Using a hacksaw, cut hose so it will slide at least two inches (5.1 cm) onto meter outlet.

5. Slide band clamp over cart end of hose, then slide hose onto meter outlet. Install clamp so it will not interfere with other hoses, clamps or meter-door handles.

6. Repeat step 1 through step 5 for remaining towers, working toward the outside.

7. Secure all hoses onto implement frame using provided cable ties. Be sure hoses will not be damaged during folding. unfolding and link flexing while running over irregular ground.

CTA4500 Hose to Seed Tube

Connect Secondary Seed Hoses

Secondary seed hose is 1.25 inch (3.18 cm) in diameter and comes in 100-foot (30.5 m) rolls. The raw hoses will be cut-to-length to connect each distribution tower outlet to a row unit seed tube.

1. Start with tower 1 (far left tower). Loosen but do not remove nuts holding tower halves together.

2. Start with tower port 1 (closest to front-center of mounting plate). Ports are numbered in ascending order counter-clockwise around tower.

3. Measure and mark expected hose length. Allow several inches of slack for wing folding.

4. Insert uncut hose into port 1. Push hose into port until seated against stop.

5. Route the hose to opener 1 (far left end of the implement frame).

6. Repeat this process by moving to the next available port on tower 1 (going counter-clockwise) and routing hose to the next available opener on the far left end of the implement frame.

7. Route hose over the entire implement frame until all openers and ports are connected.

 Some hoses connect openers and towers on different

frame sections. Route seed hoses to prevent rubbing on sharp edges or damage when implement is raised, lowered, folded or unfolded. Allow enough hose slack for implement folding and down-flex.

Refer to Figure 35

1. Start with tower Port 1 (closest to center of tower-mounting plate). Ports are numbered in ascending order clockwise around tower.

2. Measure and mark expected hose length. Refer to tables beginning on page 28 for hose-length guidelines. For example, on an implement with 6 inch (15.2 cm) rows, the hose that connects tower 1, port 1 to the 13th opener should be about 71 inches (180 cm) long.

3. Insert uncut hose into port 1. Push hose into port until seated against stop.

4. Route the hose to the opener called for in the table. Continuing the example from step 2, connect tower 1, port 1, to the 13th opener from the left.

5. Route hose over implement frame. Note that some hoses connect openers and towers on different frame sections. Route seed hoses to prevent rubbing on sharp edges or damage when implement is raised, lowered, folded or unfolded.

6. Allow enough hose slack for implement folding and down-flex.

7. When you are satisfied you have the proper hose length, cut hose.

Refer to Figure 35 (CTA4500) or Figure 36 (CTA4500HD)

8. Connect hose boot to hose by screwing hose into the boot, then connect to the seed tube by pushing the boot over the lip of the seed tube cap .

9. Repeat steps for each tower port, working clockwise around tower. When hoses have been installed in all ports, tighten bolts on tower assembly.

10. Proceed with next tower, moving right. When all hoses have been installed, check that seed hoses are long enough for wing flex and short enough to prevent hose damage. Hoses may need to be removed, shortened and re-inserted.

Diagrams for Recommended Hose Routing on CTA4500

Exact measurements and specific port-to-opener connections are unnecessary for the performance of your machine. However, if you would prefer a detailed explanation of secondary hose routing and recommended hose lengths for all towers on the CTA4500, please refer to the diagrams on page 29, 30, and 31 of this manual. These diagrams provide instructions for estimating the hose length needed to connect specified ports to their paired openers.
