While developing our G-1 F125 fixed chamber baler, we focused on the goal of designing a machine that offers true professionals the greatest impact force possible. In addition to equipping this new machine with an exceptionally sturdy design, we revisited all common "standard components" and redesigned them from the ground up.
The starting point of every firmly compressed round bale is the clean pickup of the base feed: Its pendulum suspension allows the 6-row pendulum pickup to deliver maximum conveyance capacity along with superior ground adaptation and enables it to absorb even the largest swaths without a hitch.
The suspended installation in a central position creates a swing range of 150 mm. It provides for top-notch ground adaptation and compensates for any unevenness in the terrain with perfect ease. Doing without a cam track, the pendulum pickup offers a DIN rake width of 2.20 m and large conveying screws on the sides that guarantee an optimum flow of material to the rotor. Equipped with tines spaced 51 mm apart across six rows, the pickup delivers firstrate raking performance even when handling extremely wide swaths.
Comprised of twin rollers, the standard holding-down devices with a new suspension boost the material flow even when dealing with uneven swaths and fill the bale chamber in a continuous and uniform manner.
Fitted with pneumatic tires, the touch wheels work in perfect harmony with the pendulum pickup and run with maximum smoothness. Adjusting the height of the touch wheels is quick and easy thanks to perforated rails that eliminate the need for any tools. Customers can also opt for swiveling touch wheels.
Short and precisely cut feed is the basis for the production of high-quality and high-energy silage. The material in the GÖWEIL baler flows through its own special passageway – the rotor! This feeding system guarantees optimum feed pick-up under all sorts of harvest conditions.
Fitted at the heart of the feeding system is a 6-star rotor that offers enormous absorption capacity. Thanks to its large diameter of 570 mm and the welded-on rows of HARDOX tines, the rotor will always cut the swaths of feed cleanly and convey them reliably into the bale chamber – whether they are large and dry or contain feed that is short and still wet. Installed in front of the rotor is a mechanically powered infeed roller. Precompressing the material with outstanding efficiency, the roller increases the throughput significantly. The newly developed starter roller housed in the bale chamber provides for optimum bale rotation and a reliable start.
The rotational direction of the rotor built into the G-1 F125 is upward. This movement channels the material from the rotor through the cutting unit and into the bale chamber.
As the cutting unit is positioned above the rotor, changing the blades is a breeze and can be accomplished without any tools. This offers an advantage that is particularly beneficial in baler-wrapper combinations. The cutting unit is fitted with 30 twin-blade cutting edges and makes it possible to achieve a cutting length of 35 mm. The narrow spacing between rotor tine and knife ensures that the feed is chopped with pristine accuracy. The replacement knife bar allows the operator to carry along 30 replacement knives or change the number of cutting knives as needed. A hydraulic bar safety device protects the knives against foreign objects and moves them immediately into their cutting position.
The AFC (Auto Flow Control) monitors the entire flow of material and intervenes in fully automatic fashion as soon as detecting a problem in the conveying duct. This ensures that clogs at the rotor or pickup are removed fast and without effort! Here is how it works:
Unclogging the Rotor
The rotor’s overload safeguard trips whenever the conveying duct for the quantity of feed to be delivered becomes too narrow. The hydraulic top floor opens towards the top, and the knives flip back.
When the rotor starts up again, the excess material is guided unobstructed into the bale chamber. The drop floor and the knives subsequently return to their original positions, allowing the feed pick-up to resume without hindrance.
Unclogging the Pick-Up
An overload safeguard will also be tripped if too much feed has accumulated at the pickup. Normally powered mechanically, the infeed roller will then be briefly driven and supported hydraulically to allow it to keep conveying the material. Concurrently with the infeed roller the drop floor swivels up, allowing the material to find its way directly into the bale chamber.
At the core of the machine is the bale chamber, which offers a size of 1.20 m x 1.25 m as well as 18 solid forming rollers. The steel rollers are 4 mm thick and reinforced on the inside, while their ribbed profile ensures supreme compression density and the reliable rotation of the bale.
Two drive rollers with a shaft diameter of 65 mm and the additional roller shafts with a diameter of 60 mm run continuously on double-row pendulum roller bearings and provide for exquisite stability and an exceptionally long lifetime. A specially designed labyrinth prevents dust and dirt from penetrating.
Situated directly behind the rotor, the starter roller provides for the best possible bale rotation and a reliable bale start thanks to its special profile – whether the material is silage, hay or straw. A cleaning roller feeds any material that has dropped down back into the bale chamber – keeping the machine from becoming soiled.
The tailgate opens and closes with the help of two hydraulic cylinders. Depending on the program setting, the process will be completed automatically or manually.
The round baler is equipped standard with a net binding unit. As an option, the machine can also be purchased with a film binding unit. In addition, a dual binding unit is available for film and net.
The use of a wide film offers decisive advantages that enhance the quality of the silage:
The operator can insert common wide films and nets with a width of up to 1.50 m. Binding can be started automatically or manually. The hydraulically adjustable brake roller ensures that the bale is wrapped tightly during net and film binding. The brake pressures and the number of layers can be set directly using the control.
Equipped with the world’s first dual binding unit, the G-1 breaks new ground for round balers. This optional binding system wraps the finished bale simultaneously in two nets or wide films. The result: This feature cuts in half both the time required for binding the bale and for changing the net or film! Reducing the workload significantly, this time savings will be much appreciated especially on the busiest days of the harvest. If the operator needs to alternate between silage, hay or stray bales on the same day, the machine offers them the option of using the dual film binding unit as a single binding unit. In this case, the dual binding unit is loaded with one net roll and with one roll of film. The operator simply uses the terminal to set one binding unit up for net binding or the other unit for film binding. Changing the film or the net does not cause any unnecessary idle time!
Available as additional equipment, the drive axle is of tremendous benefit especially during work in steep slope positions. It provides a powerful, yet soil-preserving push uphill, while supporting the braking action during downhill travel. The driver can concentrate fully on the work.
The drive axle offers maximum safety and superior comfort in any slope position – uphill and downhill.
The sensor system integrated in the drawbar controls the operating states – Drive, Neutral, and Brake – in a completely autonomous way. The driver can rely on the system providing maximum traction at maximum soil protection, allowing them to solely concentrate on their work. A clearly organized display continuously informs the driver of all relevant parameters.
The drive is powered hydraulically by two radial piston / wheel hub engines. The switch between forward and reverse is initiated automatically by a signal given from the tractor. The percentage of the driving force with which the drive is supposed to power the machine in first and second gear is controlled via the terminal.
When the machine is driving uphill – either in reverse or forward – the drive switches automatically from drive mode to hydrostatic brake mode. To prevent the wheels from locking up, the speed of the two drive wheels is constantly monitored and readjusted automatically. This ensures that the wheels are constantly in motion during uphill travel (ABS).
When the machine is traveling on the road, the radial piston engines are automatically released mechanically and will freewheel (no mechanical resistance).
To allow the machine to withstand even the most arduous applications under tough harvest conditions, the G-1F125 was equipped with a rugged and well-engineered drive train:
The power transferred by the PTO drive shaft to the main gearbox is spread across the drive chains of rotor, pickup and bale chamber and safeguarded individually by two cam switch couplings. The couplings are monitored by the ISOBUS program control.
When the cam switch coupling of the rotor responds to an excess quantity of feed in the conveying duct, the hydraulic drop floor will open in fully automatic fashion. When the rotor starts up again, the excess feed is guided unobstructed into the bale chamber. The drop floor closes automatically, allowing the baling process to resume without hindrance.
When the cam switch coupling responsible for the bale chamber trips, the tailgate will open automatically by a few centimeters and allow for the bale to be started and bound without hindrance.
The drive train conceived by GÖWEIL provides for a smooth work flow.
High-quality components are an essential prerequisite for the drive train’s smooth and trouble-free operation. The chains used for the main drive and for driving the pickup and the rotor in the machines of the latest generation have been increased in size yet again in order to boost the performance of the drive system even further. This extends the lifetime of the machine considerably and reduces the operation costs to a minimum.
Isobus is an internationally standardized protocol that is in charge of the communication between the tractor and the mounted implements. It allows for the real-time display of the data on the terminal housed in the tractor. The operator uses the terminal to monitor and control the machine. A standardized plug connection system has now eliminated the need for using more than one terminal for different implements.
GÖWEIL is making this baler generation available with ISOBUS as the standard option. The interface of the control is clearly arranged and easy to use. What is more, the color display shows a greater amount of information. The camera system affords the operator a good view of the work flow and the machine.
GÖWEIL offers customers a choice between two terminals:
The machines are, of course, compatible with all other ISOBUS-capable terminals. For tractors without ISOBUS, there is an optional wiring harness for ISOBUS-capable power supply available.
ISOBUS monitors and controls the entire work flow in fully automatic fashion. The clearly organized display keeps the driver informed about all steps processed by the machine. It is also possible to control all relevant work steps of the machine – quickly and easily – by hand using the terminal.
The control unit with push buttons used for the G-1 F125 Kombi comes in particularly handy when the wrapper requires maintenance and servicing. This way, the operator can control the most important functions directly at the machine.
A standard feature on the machine, the automatic central lubricator is designed to deliver superior ease of maintenance and ensures an exceptionally long lifetime for the machine.
The fully automatic grease lubricator is used to supply sufficient lubrication to all bearings of the rollers and of the rotor. The oil lubricator provides a constant supply of oil to all chains on the bale chamber, the rotor and the pickup. Brushes spread the oil evenly across the chains.
The large-size reservoirs for grease and oil provide for long service intervals.
