Floor drive gearbox 800 series
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 350 model is fitted with 2 floor drive gearboxes as standard.

One piece gearbox
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.

Rubber cushion drive coupling
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.

Floor shaft bushes
60mm floor drive shafts rotate through polyester re-inforced 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.

Floor chains
Grade 80 20mm heavy duty chains are drawn by high tensile sprockets. Sprockets are fitted to the front floor shaft as well as the driven rear shaft, ensuring perfect alignment and timing of the chains, which, in turn makes for a more reliable floor drive. Each chain has 50 tonne breaking load.
|
Full width floor slats
Full width floor slats clear the whole floor eliminating the possibility of bridging – a problem sometimes encountered with multi slat floor systems. The socket fit design facilitates maintenance, which can be carried out in the field. It also allows the chain to pull straight, should a slat become bent.

Floor chain tensioning
A robust, simple and reliable floor tensioning system ensures floor chain tension can be easily adjusted in order to be kept to its optimum setting. Floor chains are visible from the exterior of the machine making it easy to judge when tensioning is required.

20mm Floor chains
Grade 80 20mm heavy duty chains are drawn by high tensile sprockets. Sprockets are fitted to the front floor shaft as well as the driven rear shaft, ensuring perfect alignment and timing of the chains, which, in turn makes for a more reliable floor drive. Each chain has 50 tonne breaking load.
