Effluent feature: Keenan Orbital 12T

When it comes to high work rates and trouble-free operation, the Keenan legacy for robust quality manufacturing is at the forefront of delivering successful results

The Keenan Orbital 12T is a heavy-duty and versatile spreader, backed by the well-earned reputation of both its Irish manufacturing company Keenan and its New Zealand distributor Action Agriculture.

The Keenan Orbital accurately spreads a wide range of materials, including strawy muck, industrial sludge, and poultry manure, with the sealed nature of the body ensuring that sloppy material is transported and spread without leakage.

A versatile and heavy-duty spreader

The impressive list of standard features includes a slurry door, hydraulic brakes and lights, low ground pressure tyres, and a variable speed pushing door, delivering the versatility to spread most types of material without the need for costly extras.

Designed to handle such a range of farm and commercial wastes, the spread pattern is remarkably uniform. Much of the success of this is down to the combination of simple design and operation, with a semi-cylindrical tank, rear pushing door, and large flywheel at the front.

The Orbital can accurately spread a wide range of materials

A heavy-duty hydraulic ram attached to the sliding rear door pushes the material from the back of the machine towards the rapidly spinning flywheel. The forward speed of the rear door is adjusted by a hydraulic valve, allowing application rates to be easily altered. Once set at the desired level, material is fed at a constant rate to the flywheel, ensuring a smooth, consistent spread of material. For a machine with such high work rates and large capacity, the power requirement is relatively low at 120hp. Liquid materials require slightly less power. Unloading takes no longer than 1.5 to five minutes (depending on the material), with the tank being left completely clean and ready for the next load. During loading and transporting, a slurry door separates the main chamber from the flywheel so that liquids can be easily handled, and the starting torque is kept low.


With a distribution base in Te Awamutu, a branch in Gore, and Keenan service agents across New Zealand, Action Agriculture is not only the New Zealand importer and distributor for Keenan but also Seppi mulchers and stump grinders. They also have local Waikato dealerships for Hardi and Swift sprayers and Krone forage and harvest gear.
