- Model II - Vertical Self-Propelled Double Auger Mixers



The self-propelled Zenith II mixers is built on a structural frame with a double H highly resistant metal that includes two load bearing beams, the oil tank on the cabin side and the diesel tank opposite. This industrialised solution allows for mechanical cleaning (all parts are bolted), better disposal of the heat from the hydraulic oil and shorter tubing, as they are located near to the hydraulic components of the machine. The tanks are built to allow the mixer to work up and down slopes, and are fitted with electrical level sensors, and max. temperature bulb..

The following are located on the frame:

  • front steering bridge with push button control and hydraulic suspension for maximum comfort;
  • the rear, 10 column differential bridge allows the machine to move by means of Sauer Danfoss hydraulic engine, at two speeds from 0 to 12 Km/h in the first gear, and in second from 0 to 25 Km/h, and on request, even at 40 Km/h;
  • supports for the installation of the 4 weighing cells that support the mixing tub;
  • mill arm support;
  • endothermic diesel cycle Mercedes Benz engine
  • positioned transversally on 4 silent blocks;
  • the telescopic vertical arm that raises the driver’s cabin;
  • the radiators (oil and air);
  • the battery, the air filter, the various components (electrical, hydraulic) and the casing;
  • the mixing tub (in the shape of an upturned cone) is built from quality sheet metal. The 25 thick cylinder base is bolted to the weighing cells, at the centre of which the hydraulic engine is positioned, which supports the special cantilever mixing screw. This solution allows for whole round bales, even still tied, large bales, cubes of silage grass, etc. to be loaded, and the construction type also increases product mixing capacity.

The Zenith II  has a new cutting system with 2 close, overlapping mills, equipped with cutting blades. The upper mill turns clockwise, and the lower anticlockwise, thereby bringing the product into the centre, and to the loading conveyor belt.The desilaging bucket is 1900 mm wide, and the mills rotate up to a max. of 500 revs./minute. The desilaged product is conveyed to the arm where the 650 mm wide rubber load belt runs quickly (600 revs./min.), taking the product into the tub.The self-loading mill arm is high performance. It has a hydraulic engine, allowing the mill to work on all types of silage and fibrous products, and can also load floured or cubed products.Operation is electronic with a potentiometer for the choice of revolutions desired.

The new mill offers:

  • Optimised product cutting (straw-hay)
  • No blockage of load mouth
  • Reduction of wear and tear
  • Less power required during loading
  • No mistreatment of silage products
  • Reduction of work times
  • Reduction of power consumption
  • Reduction of maintenance
  • Reduction of pollution

Even the cabin design and positioning is such as to provide the operator with the best possible comfort and ergonomics, visibility and safety levels. Its slightly backwards location allows the operator to control operations during work. A large glass surface ensures excellent visibility, and 2 heated rear-view mirrors assist him in more difficult manoeuvres. The front opening is idea for getting in and out, under any working conditions, even where close to the walls with the various silages.

Having entered the cabin, the operator finds:

  • an excellent pneumatic seat providing maximum comfort, and fitted with seat belts and man present signal;
  • a steering wheel that can be height adjusted with various different reclining positions, complete with inverter and 1/2 gear speed selector;
  • a dashboard with indicators;
  • a multipurpose joystick;
  • manual and electronic accelerator;
  • programmable electronic weighbridge;
  • electronic pedal that allows him to advance slowly and quickly, by controlling the variable load pump;
  • the two-speed ventilation commands;
  • the air conditioning

A vertical arm to allow the cabin to raise, thereby easing work relating to the control of the mixer within the tub, the possibility of checking the silos in the upper part. This solution also makes any maintenance work necessary easier, and helps the hydraulic pumps and diesel engine (a manual pump guarantees raising even when the engine is turned off). An excellent lighting system allows the operator to work at night, making loading and discharge easier.

The engines are fitted transversally and are 4-6 cylinder in line diesel Mercedes Benz engines, 4.25-6,37  power turbo air/air intercooler with single injection pumps with electronically managed solenoid, ECE 97/68 phase 3 issued has a power of 130 kW (145 kW on request) – 205 KW .These types of engines equipped with a great coupler, mean that even at its lowest use and in the worst possible conditions, maximum satisfaction is obtained.

Two special ‘ELECTRONIC CUT’ hydraulic counter-knives (situated within the mixing tub) and electronically timed, and inserted by means of hydraulic pistons. Their action is guaranteed automatically by the electronic weight programming. This system reduces working times by approximately 50%, eliminating the loss of the product to be mixed.

4 hydrostatic pumps Sauer Damfoss with variable load, electronically controlled pistons guarantee the screws functioning, the moving of the machine and the rotation of the mill. They are in line with the engine bolted to the flywheel. A gearing pump guarantees the functioning of the hydrostatic power steering. The LS piston pump (LS=Load Sensing) provides the innovative, technological input for the operation of the various moving parties. The electronic control of this pump allows the user to manage the oil flow, depending on the required power and speed of each moving part. As such, the hydraulic oil heats less, because the pump only allows the oil to flow through following a received signal, alternatively it is left in the ‘rest’ position. Hence less enginenpower used, and a reduced fuel consumption and deterioration of hydraulic oil.

This pump system makes the following possible:

  • installation of a potentiometer for the discharge surface, which regulates movement on the basis of the speed required by the operator;
  • the installation of a proportional joystick that regulates the movement of the mill arm (quick and slow);
  • the fixed regulation of the moving parts that must maintain the same speed, even when engine revolutions vary (from 1000 to 2500 revolutions/minute of the engine).
