The optimal solution for rectangular areas

The BAUER Linestar

The LINESTAR system 9000 from BAUER is the best irrigation solution for large rectangular fields. In contrast to the pivot, which moves in a circle, linear systems have a central unit that moves linearly across the field together with the tower units. Across the field and back again. A special linear control always keeps the machine on the right track. Perfect alignment and automatic correction of deviations between the towers are possible even on challenging terrain. The water is supplied via hydrants and a supply hose or from a ditch feed. A generator system in the central unit ensures a mobile supply of power. The LINESTAR performs best in long rectangular fields, where it can achieve almost 100% space utilization. It stands out with lower operating costs per hectare compared with other forms of irrigation.


  • Optimal area utilisation in rectangular fields (up to 100%)
  • Lower operating costs per hectare with oblong, square fields compared to the classic Pivot
  • Irrigation which is gentle to soil and crops
  • Low pressure system with low energy consumption
  • High level of irrigation efficiency thanks to the ground-level water distribution

Span – trussing

  • Five different tube diameters provide a wide application range (50-600m³/h)
  • Optimum adjustment guarantees lowest operating costs
  • Only one pipe length (5.85m) for easy assembly and transportation
  • Truss rods, diam. 20mm, with high tensile strength and large safety reserves
  • Even arc shape of the trussing ensures high degree of stability
  • The 90° arrangement of the bracing angle ensures a uniform load distribution in the most difficult terrain
  • Crossed drive tower braces for high stability on uneven terrain
System 9000 brings more stability

Drive tower

  • Broad based construction
  • Optimal power input
  • Large-dimension drive tower bracing angle 100x75mm
  • The wide wheel base of 4.3m (standard) and 5.2m guarantees a high level of stability, even on rough terrain and in strong winds
  • 2 construction heights of 4.2 m (standard) and 5.0m for optimal adaptation to different crops
  • Towable - high level of flexibility and adaptation to crop rotation
Precise and reliable

Tower coupling

The sturdy drive tower coupling, free from play, with ball and socket perfectly compensates for extreme slopes. Mounted on the outside of the pipe, it does not restrict the cross-section of the mainline pipe, thereby ensuring optimum water flow without pressure loss. The weather, UV and ozone-resistant hose collar facilitates large angles.

Patented by BAUER

Alignment control

BAUER is the only manufacturer to offer a control lever that is mounted directly above the swivel point of the flexible joint. Any torsion in the pipe has no influence on the control; the entire system is kept stress-free. Optimum adjustment of switching brackets with precision bearings of the control cams ensures precise movement transmission. Precise drive tower control system leads to a long product lifespan.

Highest precision for more than 12 towers

Precision control

The precision control for all Linestar and Centerliner systems (regardless of the number of spans) and for Centerstar systems with more than 12 drive towers offers utmost accuracy. The angles between the drive towers are transmitted by means of control cables, counter-balancing any torsion in the steel structure.

Control units
Perfect irrigation management

Control units

Tried and trusted sturdy elements for application under the most extreme conditions. Easy-to-use control surface and robust control elements to ensure smooth operation. All of the basic functions for automatic operation are integrated into all of the control centres.

Linear Guidance

GPS Control

Using GPS modules and an RTK base station, the ACTUAL position is constantly compared with the TARGET position of the machine and corrected immediately if necessary. GPS control is available as an option for Linestars and Centerliners with a 4-wheel central unit and SmartTouch control box.

Advantages of the GPS control:

  • No obstacle in irrigation area
  • No digging and field maintenance required
  • No maintenance work

Buried guidance wire

Sensors track the induction field of a buried cable and thus indicate the moving direction (available for Centerliner and Linestar).

Advantages of the buried guidance wire:

  • No obstacle in irrigation area
  • Permanent indication of deviations from the ideal line
  • Simple programming and implementation
  • Assembly height of up to 3m above buried cable
  • No maintenance work



Cable guidance

The steering arm with its pulleys moves along a stretched cable, thereby determining the moving direction of the machine.


Furrow guidance

In order to control a Linestar or Centerliner, a furrow is created along the route in order to determine the moving direction of the system
