Machines fitted with slurry doors have Automatic Light Covers as standard. A simple mechanism triggered by the slurry door, moves the light cover over the lights as the slurry door begins to open.
The 800 series floor drive gearbox is hydraulically driven to ensure an even feed of material to the spreading mechanism at all times. With a reverse feature, any foreign object too large to pass through the beaters can be easily removed. An adjustable cross-line relief valve also delivers additional protection. The Widebody 320 & 380HD models are fitted with 2 floor drive gearboxes as standard.
The robust one piece gearbox houses internal gear sets unique to Bunnings in order to ensure that auger speeds are optimised to achieve excellent spread patterns. They are large in diameter with 54mm output shafts manufactured from heat treated steel. The precision machined castings ensure perfect alignment of all the driveline components.
60 mm high tensile floor shafts rotate through Polyester re-enforced composite bushes that contain a solid graphite filler. Chosen for their high load applications in a variety of environments they are greasable, further extending their life. Bush highlighted in red.
Full width floor slats clear the entire floor area, eliminating the possibility of bridging, a problem sometimes encountered with multi chain and slat floor systems. The “socket fit” design allows for easy maintenance which can be carried out in the field, it also allows the chain to pull straight should a slat become bent.
16mm, grade 80, heavy duty chains are drawn by high tensile sprockets, which are fitted to the front shaft as well as the driven rear shaft, ensuring perfect alignment and timing of the chains. Each chain has a 32 tonne breaking strain certificate. The same specification chain is used throughout the Mk4 range
When machines are fitted with a slurry door the LED lights are automatically covered when the door starts to open.
Especially developed to reduce shock loads to the auger drive gearbox, the rubber cushion arrangement located between the output shaft of the auger gearbox and the base of the auger contributes to the reliability and longevity of the machine.
Twin 27″ diameter dynamically balanced vertical augers have flights laser cut from heat treated Boron steel to improve strength and service life. Reversible Hardened Boron points manufactured using heat treated Boron steel are bolted and supported along the back edge.

The GT 400 not only displays the live weight in the machine but also allows the operator to add the total weight up by pressing the start/stop button after every load. This simple weigh unit can be fitted through the whole range of Bunning muck spreaders from the 60 to the mammoth 380HD. The system is integrated with the same load cells as used on the popular and proven RDS Apollo psi indicator.
If preferred, a tandem axle rocking beam option is available on these models. Standard rocking beam wheel equipment would be 16.5L x 16.1SL other alternatives are available so please contact us to discuss these options.
Built in flared extension sides add considerable carrying capacity to machines, spreader design load capacity should be checked relative to the density of the material to be carried. This option is not available for machines that are to be containerised for transport, the bolt on option should be specified.
These ultra bright LED flashing/strobe lights are fitted as a pair and give a highly visable warning.
These bright LED marker lights are fitted to the front & rear of the mudguards and give a positive marker to the overall width of the machine.
While Bunning Blue or Bunning Green are our standard colours. From a BS or RAL number we can paint your machine in almost any colour.
Higher Augers are available as a factory build option for the Lowlander 75 & 90. They increase the height of the augers by 12″.
The RDS Apollo spreader controller has all the features for today’s farming techniques. Target application rate is entered into the controller which then monitors the load and adjusts the floor speed accordingly. GPS variable rate technology is supplied as standard and the system can receive an application rate from a third party controller such as John Deere Greenstar, Raven or Trimble. Or a predefined application map can be loaded to the SD card and automatically vary the rate (Precision Farming). Data can be logged via the optional printer
or saved to a SD card, which can then be exported to an Excel spreadsheet along with treatment maps. Live weighing is via 20 tonne weigh cells situated on both axle and drawbar. This is then clearly viewed on the controller screen together with your speed, target rate and live application rate. There is a choice of either using the machine in ‘Automatic or Manual Control’ depending on your requirements.
A choice of either 2 Line Air Only Brakes or Dual Supply (2 Line Air and Hydraulic) Brakes.
This options allows the operator to monitor door opening positions in relation to application rates
To help clean out the deck area around the bottom of the augers these covers can be opened to allow material and water to flow out
To reduce the scrub on tyres and damage to grassland when turning. Both the 320 & 380HD models can be ordered with either one (rear as standard) or two (front and rear) self-steer axles.
Designed for use when spreading low applications of products like Lime and chicken litter, the canopy ensures that all material is spread by the bottom auger blades
This option can help to increase the spread width of some finer products spread at low application rates and are most effective when used in conjunction with a Simple Canopy
To enable the machine to be used for other jobs the auger assembly can be removed for the faster unloading of products such as grass, maize silage and even grain
This compact printer is connected to the RDS Apollo Controller and produces a receipt which can be printed off showing Start & Finish Time, Job Number, Farm & field Number, Target Rate, Total Area and Total Weight. This can be kept for your records or supplied to your customer as a receipt for work complete.
A specialist auger design for machines that are purchased primarily to spread Bio-solids (sludge cake)
This option includes floor slats positioned on alternate flat links on the floor chain and angled pressings on the rear of the machine to prevent sticky product building up on flat surfaces
This option is designed to protect the PTO shaft from damage by the tractors lift arms.
A robust item designed with a sloping lid to reduce the build up of material
The wide angle joint allows for turning on headlands with the PTO still engaged. It should be noted that the manufacturers recommend that you do not turn with the PTO under load.
An extremely strong design and construction ensures that the door can be used as a grading device for light applications of materials as well as a device for retaining very running products.
As an option the machine can be manufactured to take weigh cells at a future date. The dummy weigh cells can be easily removed and replaced with full weigh cells.
The in-cab electric remote floor speed control allows the operator to make adjustments to the floor speed while on the move.
The Sprung Heavy Duty Drawbar uses a 21 tonne spring and comes with a bolted clevis hitch
As an option the rear canopy can be opened hydraulically to enable the machine to make windrows for composting or for ease of maintenance. Safety props are supplied and should be used prior to carrying out maintenance.
Detachable spinner deck can be attached to the rear of a vertical auger spreader in just a few minutes. Once fitted, products such as chicken manure, composts and lime can be spread evenly and accurately at low application rates.
Twin 34″ diameter dynamically balanced vertical augers have flights laser cut from heat treated Boron steel to improve strength and service life. 3/4″ thick reversible points manufactured from heat treated Boron steel are bolted and supported along the back edge.
