Bauer’s new Rainstar A4 reel irrigator, which will be presented at LAMMA 2026, offering a compact, high-performance solution for irrigation across smaller fields.
Bauer to Showcase Rainmaster A4 Irrigator and New Slurry Tanker Features at LAMMA 2026

A new Rainmaster clean water reel irrigator and new features for slurry tankers will be among the highlights of Bauer’s stand in Hall 7 at the LAMMA show in January.
New A4 irrigator
The event at NEC Birmingham on 14/15 January will mark the UK launch of the Rainmaster A4 series reel irrigator, which neatly enters the range between the current compact A series and larger T series, and will be shown alongside a latest-generation Rainstar E300 110/490.
Catering for use in smaller fields across all agricultural and horticultural cropping and livestock enterprises, the Rainstar A4 is available with Bauer’s own polyethylene (PE) hose in diameters up to 75mm and in lengths up to 250m.
Flow rates of between 12 and 48cu m per hour help users fine-tune their irrigation schedules, and Bauer’s wide-angle SR101 sprinkler delivers uniform water distribution across runs up to 70m wide, with boom systems available as an alternative to provide gentle irrigation of delicate crops.
Like other mobile irrigators in the range, the A4 is built with galvanized steel components and high-performance PE hose manufactured by Bauer at its headquarters factory in Austria, where strict quality-control protocols ensure consistently high standards.
The new A4 joins a comprehensive line-up of Rainstar reel irrigators with a distinguished reputation for reliability, durability, accuracy, performance and ease of use – the last two of those enhanced by the SmartRain irrigation app for mobile devices.
This provides alerts, reports and control functions for remote irrigator management, and easy access to an online documentation and reporting platform.
The SmartRain package enables users of Bauer Rainstar reel and Centerstar pivot irrigators – as well as Bauer diesel irrigation pumps – to keep track of just one or several irrigation systems via an office computer, an Apple or Android mobile phone, or a tablet computer.
New slurry tanker features
Bauer will also exhibit one of its signature poly-tankers, a 21,000-litre tandem axle unit featuring a new contactless forced steering system for the rear axle.
The machine will also highlight new field application control software with field mapping, and a Vogelsang 24m Swing Max5 dribble will illustrate the range of application hardware available.
Bauer’s high-specification poly and steel tankers are produced in the main for large farms and contractors handling big amounts of slurry from dairy, pig and other livestock units, or digestate from anaerobic digestion (AD) biogas plants.
Robust build, considerable variation in terms of features and layout, and good road manners during high-speed road travel between store and field are key features appreciated by professional users.
Then there are the unique characteristics of Bauer’s poly tankers, which have a container built from hand-layered woven polyester sheets, a weight-saving solution that is impervious to corrosion, emphasises Rob Jackson, area sales manager for Bauer in the UK and Ireland.

Rob Jackson, area sales manager for Bauer in the UK and Ireland:
"Finished with an outer layer of Gelcoat that protects against the tank’s otherwise corrosive effects of its contents, as well as exterior contaminants and the elements, the poly tankers’ structure and galvanised chassis means they clean up really well and can look like new even after a lot of use, resulting in strong re-sale values."
Examples of Bauer’s comprehensive range of Helix, submersible and pto-driven pumps will also be on the LAMMA show stand, alongside slurry separators illustrating the wide range of slurry separators from Bauer and FAN Separator, a Bauer subsidiary.
They will include a FAN PS3.3 Green Bedding unit capable of producing a soft lining material for cow cubicles, and an Elevator fully-integrated mobile set-up with variable discharge height.
