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
50mm 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 16mm 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 32 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 drive gearbox
The 500 series floor drive gearbox is fitted to all models with the exception of the Lowlander 60 and 150 (fitted with 350 series and 800 series respectively). |
Floor tensioning system
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. Floor shafts are 50mm diameter (60mm on the 150 model), both |
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. |
Twin dynamically balanced vertical augers
Twin 690mm diameter dynamically balanced vertical augers have flights laser cut from high tensile steel to improve strength and service life. Reversible Hardened Boron points manufactured using EN8 steel are bolted and supported along the back edge. |
