made up by a maximum possible quantity of identical parts. Thus it is easily possible to adapt different span lengths.

Bolts: DIN-grade 8.8 with lock nuts Tower coupling: The sturdy ball joint allows optimal adaptation to the different torsional strains caused by

unevenness of ground and different span lengths. The coupling mounted outside of the pipe causes no necking and allows the irrigation water to pass without any hindrance. Both coupling elements are vertically flexible up to 16°

Pipe connection with hose collar, made out of finest quality, weather proof, UV- and ozone resistant material. ../4

The alignment control ensures maximum control exactitude and operation safety.

Control angle ± 0,15 degree from neutral position. BAUER as the only manufacturer supplies a switch lever which is directly coupled to the

flexible articulation (BAUER patent) securing an exact transfer of movement to the tower switch box. Hence the impulses are not influenced by uneven ground.

Monitoring system with high performance electric elements, withstanding tropical

condtions. The ample dimensioned circuit elements are protected by a solid plastic shield which is

fastened by spring vices, suitable also for high wind velocities.

Spray Nozzle Equipment Low pressure spray nozzles type Senninger: LDN For the low pressure spray nozzles, BAUER propose a minimum nozzle pressure of 1,0

bar to enable fine drop resolution. The spray nozzles are mounted on the main pipe. All spray nozzles have different colours to distinguish more easily the sizes. The nozzles

are inserted simply by hand by turning them in - no tools necessary - especially advantageous when nozzles are blocked.

The tough and high quality Thermoplast spray nozzle has a longlasting durability and is

highly wear resisting. The nozzles are equipped with interchangeable, grooved rebounding plates. To secure uniform water distribution in hilly terrain, all spray nozzles are equipped with

pressure reducing valves. Distance between the spray nozzles: 2,925 mm To avoid excessive irrigation in the driving tracks, half-circle nozzles of 180° are used on

both sides of the tower. For the hydraulic calculation of the Pivot supply pressure, please refer to the computer

prints. 6. Flexible Drop -pipes Steel bend 180° galvanized -both sides with threads 3/4" Flexible hose 3/4" , 2,5m length Stabilizer pipes 0,5m length (drop pipes supplied in parts for local assambling)

Technical Advantages of BAUER Compared to other Pivot Suppliers.

1. Bauer uses main pipe lengths of 5,85m. The competitors use up to 3

different pipe lengths ranging up to 13,4m. Advantage: Easier for manufacture, less inventory for dealer, less complications during erection.

2. By using a pipe lengths of only 5,85m, the weight is low which makes the handling during the installation much easier. Advantage: 2 people can lift the main pipe by hand. With the larger pipes offered by competitors, a crane is needed to support the weight.

3. BAUER uses only one truss rod length; Competitor are using different length and different diameters. Advantage: BAUER makes it easy; a simple construction and saves inventory space for storage of parts.

4. Bauer uses 5 different truss angle packages. Other suppliers use up to 7 different angle packages. Advantage: There are less components needed on stock and the erection of machines is less complicated.

5. Bauer offers the most universal parts of all the suppliers. Advantage: Stock is reduced, less spare parts, less training for service people easier installation..

6. Bauer flexible span connection with ball and socket coupling offers a large angle for undulating ground (uneven surfaces). Advantage: Span coupling is used for both; flat and uneven surfaces but some competitors (Lindsay type) have a standard and special coupling for rough surfaces.

7. The Bauer uses the largest wheel base of 4,3 m for drive towers Advantage: The span is more stable than competitors. An example is in France during massive storms, competitor pivots were overturned while the Bauer machines were unaffected.

Page 1 of 2

8. Crop clearance for BAUER Pivots are 3,1m Advantage: American producer are offering 2,8m for long spans; crops like maize can be damaged.

9. All of Bauer components are hot dipped galvanized according to

DIN 50976 which is a higher standard than that used in the United States. Advantage: American based companies galvanizing is therefore of lower quality.

10. Bauer always uses new tires with a dimension of 14,9-24 and galvanized rims as standard. Competitors use a tire dimension of 11,2-24 and mostly use retread tires. Some of the rims are only painted and not galvanized. Advantage: greater corrosion protection and higher quality

Page 2 of 2

11. Tower alignment between spans is measured from very close to the flexible join and so the angle deviation reading is as accurate as possible.

12. The Bauer alignment control box is not effected by torsion caused when travelling over uneven surfaces or obstacles. This means that a true angle reading is always given.

13. The cams in the alignment control box are larger in dimension than all of the competitors. Advantage: Switching points for angle alignment are easily set and very accurate even with small variations over time.

14. Alignment control boxes are delivered with a standard setup which has been tested

before leaving the company. Advantage :Easy to install, no settings of micro switches.

15. The Bauer tower control boxes contain specially treated micro switches for completely

safe operation even under extreme climate conditions Advantage: Guarantees a accurate trouble-free operation under worst climate conditions. .

16. The main control box from Bauer is manufactured in accordance to the strict ISO

regulation necessary for Austria, Germany and other European countries. The US standard for electricity safety is much less strict. Advantage: Bauer control boxes have a much higher electrical safety,

17. The components used in a Bauer control boxes are from high quality and well know

manufactures such as Siemens, Schrack, Schneider Advantage: replacement parts can be easily found from local suppliers of electrical goods.

18. BAUER offers the highest possible

comfort in packing. All important parts of the towers are packed in wooden boxes. Small parts, such as bolts or nuts, are vacuum-packed in special plastic bags Advantage: Saves time for erection and prevents loosing small parts in the field

19. The cables for Pivots are pre-assembled, which

means that they are trimmed to the right length and equipped with cable eyes, Clear advantage: Facilitates the assembly of the plant, and this saves time

As nozzle sizes increase along the length of a pivot, extra deflector pads are added to accommodate the higher flow. Theincreased area of coverage provided by this multi-pad system aids in the reduction of instantaneous application rate, reducingrunoff and surface compaction.

0.5 to 5.25 gpm 4.0 to 9.5 gpm 6.75 to 14.5 gpm

• Multiple-level deflector pads to handle the higher flows on the middle to outer spans

• Mini deflector pads available for smaller nozzles

• Chemigate pads available: Corn (58°upward throw) and Cotton (15° - 30° multi-level upward throw)

• Hosebarb adapter available for direct furrow water application

• Color coded nozzles for easy size identification

• 3/4" NPT male thread

• Two-year warranty on materials, workmanship and performance

The Senninger Low-Drift Nozzle (LDN®) fea-

tures a unique multiple deflector pad design.

This allows it to produce uniform sized droplets

through the wide range of nozzle flows found

on center pivots. The result is extremely effi-

cient water application with minimized losses to

wind drift, evaporation and runoff.

Lowest instantaneous application rate

Ordinary spray nozzles place water in a ring at the outer edge of their wetted circle. This causes higher application rates, soil compaction and an increased chance of runoff.

The i-Wob uniformly covers the inside of its wetted circle.This means it is wetting a much larger area at a much lower instantaneous application rate.

In this example, the i-Wob is wettingover four and a half times the area of the spray nozzle. (Nozzles are at 20 psi, a 6' height,using a 11/32" nozzle, with a flow of 14.3 gpm in no-wind conditions.)

Page 8 — Senninger Irrigation Inc. (407) 293-5555 — Pivot Catalog

The Senninger i-Wob uses a unique off-center

rotary action to provide outstanding uniformity

at low pressures. Its new below-the-nozzle

weight creates less stress on flexible drops.

Excellent distance of throw

The action of its wobbling shroud allows the i-Wob tothrow water much farther than spray nozzles with stationary deflector pads. (In this example, nozzles are at 20 psi, a 6' height, using a 11/32” nozzle, with a flow of

14.3 gpm in no-wind conditions.)
