Procedures and Information
Irrigator towing procedure
Preparing to tow
1. A Irrigator Towing Checklist must be filled out during the towing procedure
2. Align Irrigator on tow path aiming to get the end tower centred on the path (If the end tower is not visible it is possible to climb one of the towers towards the end and stop the machine with the safety shut off switch. Ensure that the switch is turned back on after the pivot has stopped)
3. Stop irrigator and switch off generator
4. Close control panel door, disconnect earth clamp and then hang earth cable over control door to ensure it will not open.
5. Turn off main line valve, release 200mm flexible hose clamp on the pivot riser pipe to release water pressure and then disconnect flexible hose from main line valve.
6. Cover main line valve with steel plate.
7. If the centre tower is aligned correctly for the tow the tower wheels can be turned before releasing the tie down chains.
8. If the centre tower is not aligned for the tow it must be aligned and hooked to towing vehicle prior to turning the pivot wheels into the tow position.
9. To realign the centre tower (while the pivot wheels are in the watering position) release the tie down chains.
10. Jack up each wheel of the centre tower in turn and turn the wheels to allow the unit to be turned.
11. Pull the centre tower into line with a vehicle hooked to the drawbar.
12. Hook towing vehicle onto towing frame
13. Connect safety chain to towing vehicle.
14. Jack up and turn all the pivot wheels into the towing position.
Safety issues around using hi- lift Jacks
Manual jacking can be dangerous particularly on soft and sloping ground.
The handle can fly up and injure the operator
• Always use genuine “HiLift” jacks
• Check mechanism for reliable operation
• Use extended handles for improved leverage and control
• Keep head away from over the jack handle when using the jack
Towing vehicle and person assisting must have UHF radio communication
1. Check radio communication
2. Proceed with tow ensuring the pivot tows easily and without allowing the pivot to roll backward.
3. Tow at around 2 – 3 km/hr at a steady rate.
4. Approaching the pivot pad align the towing vehicle with the painted lines.
5. If using the bulldozer place truck tyres on the pivot pad
6. Tow onto the pad with the person assisting to stop with the riser pipe dead centre over the centre mark.
7. Tie down the centre tower with the chain twitches before disconnecting the towing vehicle.
8. If the centre tower is not aligned with the tie down chains, jack and turn all the pivot wheels before disconnecting the draw bar and aligning the centre tower.
9. The pivot riser pipe must be within 100mm (half the width of the pipe) of the centre mark on the concrete before chaining down
10. The pivot irrigator must not be reversed. Ensure that the pivot is stopped with the riser pipe within 100 mm of the centre mark on the concrete slab.
11. Place the wooden blocks under the foot of the centre tower legs.
12. Connect flexible hose ensuring that the hose is resting on the rubber mat and that the clamps are securely attached
13. Connect earth clamp to copper rod in the hole in the concrete slab (Wheat pdk and South Bells have the rod on the western side of the slab next to the concrete)
14. Turn all pivot wheels to watering position before starting generator.
15. Start up irrigator as per the start up procedure
Pivot end tower is centred on tow path
