Ever wondered what happened to all of those waste trucks emptying bins all over Australia go after their use by date is up, well this is where Accos go to die. Working in the paddocks of Western Australia. The waste body is removed and the PTO and hydraulics come in handy as they are transformed into hay bale stackers.
This great bit of kit was devised by WA Wheatbelt & Great Southern who have designed, built and now operate these self propelled stacking machines as part of their business. Based in Beverley WA, the company run a hay logistics business, MHS Logistics, running their own mobile hay stackers and a couple of B-doubles to move the bales from A to B.
To make the the mobile hay stackers, the chassis gets lengthened and the engine moved back to get the weight balance right. The engine runs up to and around 1200 rpm all of the time as most of the work is being done by the PTO and the hydraulics.
Using the joystick controls on the left hand side of the dual control truck to control the lift mechanism, the drivers sits on one side when loading and the other when travelling on the highway between jobs.
The grab gets hold of the bale before lifting it directly above the cabin. It is dropped onto the the 15 degree ramp. The arms turn the bale onto its side before it slides slowly to the bottom of the ramp. This process continues until five or seven bales are loaded. These are followed by another five or seven at the top of the ramp.
The bales are unloaded seven at a time and a smart ram offsets the top two bales as they are lowered to add to the stack. The next seven then slide to the foot of the ramp and are unloaded in the same way
The design has been made flexible and each hay stacker is different, depending upon the equipment available in the donor vehicle.
