Having had a foot in both farm contracting and machinery sales Wox Agri Services has developed a range of slurry kit under its own name, as well as continuing to distribute the Güttler range of machines. We visited the Northumberland business open day to learn more.

Helen and Geoffrey Wox have been working with Hans and Gisela Guttler since the early days of the business.

KEEPING IT BRIEF

  • Wox Agri Services was established by Geoffrey and Helen Wox in 2006 based near Morpeth in Northumberland.
  • Is the UK importer for Güttler and Cornell while also distributing Golmer & Hummel umbilical hose and Metal 360 Couplings.
  • Key export markets for slurry systems include New Zealand and Scandinavia.

When it comes to experience, Wox Agri Services has been both a customer and supplier. Geoffrey Wox originally established himself as an agricultural contractor while also working alongside his father who had a machinery dealership with the Fendt agency as well as Fortschritt swathers. The family moved to their current Station Road site in Morpeth in 1981. Indeed, the former workshop is now home to the fabrication area with newer buildings for assembly and storage.

Wox Agri Services has done its own design and development work over the years with Güttler machines adding such as this aerator attachment it showed at Bath & West Grass in 2018.

One of the longest and best-known partnerships has been with Güttler. Geoffrey met Hans in 1991 at Agritechnica when it was held in Frankfurt. The contracting business was operating a Dutzi rota soil conditioner and the prisma roller caught their eye. After that, Wox started selling the rollers as a retrofit item before later taking on the distribution from RECO in the UK. Ever since the two have been working closely, with Geoffrey, his wife Helen and the rest of the small team based at Station Road even doing some of their own development work to open new opportunities with the Güttler products. For instance, it makes a storage platform for extra bags of seed on the GreenMaster, and even developed smaller ‘Mini’ 1.8 and 2.2m wide versions for establishing grass and other crops on restoration works or around solar farms. There have also been bigger projects such as the 6.0m wide, fully-mounted GreenMaster Compact (see profi 10/2026 for a driving impression) and the tine drill version of the Supermaxx cultivator. Products, where Wox Agri Services spotted a potential market in the UK.

In recent years Wox has expanded its range of slurry pumps. The pto-powered Walrus combines a charge pump on a boom feeding and umbilical system, but using the pneumatic valves allows the flow to be redirected back to the store for mixing.

Slurry kit

Umbilical slurry spreading was one of the main jobs undertaken by the contracting business Geoffrey was running in the 1990s and early 2000s. The firm started to build its own reelers in 2009 and employed engineer Edward Collins to help do the design work as well as operate machines. On a trip to the US in 2010 to look at ways of boosting efficiency with an engine driven pump.

“I went out there to see how we could do the job better, but when I saw the pumps and the size of the pipe they were using I thought we should be selling this stuff, not just using ourselves,” recalls Geoffrey. This is where he also spotted the Cornell pumps which use hardened white iron for the pump housing, which is much harder wearing to deal with the abundant amounts of sand used in bedding over there. Since then, Wox Agri Services has added Cornell to its product range and is its first choice for the likes of the Invader and Walrus pumping systems.

Hose humpers are something that Wox has been championing for use with larger diameter drag hose.

Other products it now handles include the Gollmer and Hummel umbilical hose which comes in various thicknesses from 3.2mm to 4.5mm depending on the type of work.

“The products are there, we know their uses and we can give recommendations,” points out Geoff. “For instance, we have pipe which is more resistant to flint damage, especially in dry conditions, but it’s not as flexible. Bigger pipe size also takes less energy and more flow. We are seeing more farms install 8-inch underground mains, it is a cost, but saves diesel and time.”

At the open event, a section of Golmer & Hummel 5″ PU Drag Orange hose with the 360 Coupling showed its strength while a Fendt Vario 1050 held on to Wox’s Favorit 818. 

Slick fabrication

Today, Wox Agri Services employs six full-time staff alongside Geoff and Helen. The Wox range of slurry-related kit is being expanded with the Tempest C front reeler with integrated compressor being the latest creation.

Metal cutting is outsourced, but all of the welding is carried out at Station Road. New pulse welder has improved the time and finish of the welding.

The premises has also expanded. The former dealership workshop is now the fabrication area. All of the metal cutting is sub-contracted out as the team includes two engineers who are able to create the CAD drawings for other firms to work from. The business has recently invested in pulsed welding hardware, which produces less spatter, better control of the weld pool and less heat distortion.

Various components ready for assembly after being galvanised.

The prominent engineering area of the North East also makes it easier to get parts galvanised before being returned to Station Road for assembly. In 2021, a new clear-span building was erected. Part of this has been kitted out with an overhead crane for assembly work while a number of other bays are retained for storage of finished machines and larger components.

Neighbouring the assembly area, stock machines and parts are stored under cover.

As well as supplying the UK market, Wox Agri Services is increasing sales in exports. “New Zealand is a growing market for us along with Norway and Sweden,” says Geoffrey. “We sold our first Invader pump to New Zealand in 2019 after a contractor had seen it working in a YouTube video. Internet based telematics help us with any fault finding.”

In 2021 assembly shifted to a new building, offering more space for larger implements.
The latest product to be developed at Wox Agri is the Tempest C, a front-mounted reeler with integrated compressor.
