1. When using the implement and the driveline, do not exceed the speed or power limits specified in the operator s manual. Do not overload the implement or suddenly engage the PTO clutch. Any torque limiter or clutch must be installed on the implement end of the driveline. Use the implement only with the original driveline, which is fit for the purpose in terms of length, mechanical strength, clutches or torque limiters and shields. 2. All rotating parts must be shielded. The tractor master shield, the driveline guard, and the implement shield all work together for your safety. Do not operate without all driveline, tractor and implement shields in place. Damaged or missing parts must be repaired with original spare parts or replaced before using the driveline. The driveline must be securely attached at both ends. Guards must turn freely on the driveline. 3. Ensure that the driveline is securely attached to the tractor, and the implement before operating. Check that all fixing screws are tight. 4. Keep clear of the work area and rotating parts. DO NOT wear loose clothing, jewellery, or hair that could become entangled with the driveline. Contact with rotating parts can cause serious injury or death. 5. Before approaching the implement or performing maintenance work be sure to turn off the tractor engine and remove the key then disengage the PTO. 6. Illuminate the driveline operating area when used at night or in poor visibility. 7. Keep the driveline horizontal during handling to prevent the sections from sliding apart, which could cause injury or damage to the shielding. Use suitable means to transport heavy drivelines. 8. The telescoping tubes must always overlap by at least half of their total length, in normal operation and at least a third of their length in all working conditions. During manoeuvres, when the driveline is not rotating, the telescoping tubes must have a suitable overlap to maintain the alignment of the tubes and allow them to slide freely. 9. The driveline and its torque limiter or overrunning clutch are designed specifically for the implement, and should be used exclusively for that purpose. Check the implement instruction handbook to ascertain whether the driveline must be equipped with a torque limiting or overrunning clutch. Standard drivelines, torque limiters and overrunning clutches are designed for speeds of up to 1000 RPM. 10. Ensure that the driveline can perform all operations without interfering with the tractor or the machine. Any contact with parts of the tractor, hooks, drive pins, tyres, drawbar, hammer strap, or 3-point hitch, will damage the guard. Never use a tractor, (or a system to connect the implement) that interferes with the driveline during operation. DO NOT use adapters, or components not offered by the implement manufacturer. 11. Attach the driveline, guard restraints & chains. Best results are achieved when chains are attached nearly perpendicular to the driveline guard. Adjust the length of the chains to allow sufficient slack for full movement of the driveline during turns, operation, and transport. Avoid excessive slack, which could cause the chains to roll around the driveline. 12. Never use the safety chains to support the driveline in storage. Always use the support provided on the implement. 13. DO NOT stand on the driveline. DO NOT step over or go under the driveline. 14. Friction clutches may become hot during use. DO NOT TOUCH!! Keep the area around the friction clutch clear of any flammable materials and avoid prolonged slipping of the clutch. SAFETY AND WORKING CONDITIONS 15. The tractor printed on the shield indicates the tractor end of the driveline. Any safety device should be installed on the implement side. E & OE 3
1. The size of the driveline must be selected according to the functional requirements of the application. 2. The needle bearings of the cross journal must be suitable for the required torque, speed and joint angle. SIZE, TORQUE AND POWER 3. Agricultural implements are often subjected to overloads and torque peaks that are difficult to quantify. Torque limiters are available to help prevent possible failure of the driveline or other components. The setting of the torque limiter may also be used as a reference in proper sizing of the driveline. A suitable type of torque limiter must be selected according to the duty cycle required. The torque specification must be selected according to the median torque transmitted M and the peak torque (M max for the driveline). 4. Ratchet torque limiter & shear bolt torque limiters are used on implements whose duty cycle is constant or alternating with possible overloads or torque peaks. The setting of these torque limiters is generally 2-3 times the median torque M. 5. Friction torque limiters are used on implements whose duty cycle is alternating with frequent overloads. A friction torque limiter allows these frequent overloads to be accommodated without stopping the driveline. Overloads during operation can be overcome without interrupting the transmission. The setting of the friction clutch torque limiters is normally about twice the median torque M. 6. When setting the torque limiter, we recommend that the proper safety parameters are derived according to the strength limit of the entire driveline.

The driveline tubes allow power transmission from the power take off to the power input connection of the implement. They also compensate for any length variation occurring during operation or transport. The most important characteristic of a shaft is its torsional strength which should be large enough to withstand the torque to be transmitted under all predictable conditions. The torsional strength of a driveline is defined by the maximum torque that can be transmitted via the tubes. The size of the driveline must be chosen so the maximum torque exerted during all predicted operations determines the maximum torque that can be accommodated by the tubes. Machines used in agriculture are often subjected to loads and torque peaks that are not easy to control. One important consideration is the use of torque limiters. Another important consideration is the telescoping capability of the drive tubes. Drivelines must vary their length according to the requirements of the application. Another important property of tubes is their capacity to slide under load while producing low telescopic thrust forces. Thrust forces create axial and bending loads that are transmitted to the universal joints, the power take off and the power input connection shafts and their bearings reducing their life. The ability to slide under load while producing low thrust force as expressed by the ratio thrust over torque is an important factor when choosing tubes. Lubrication of tubes is vital to reduce thrust forces and help prevent wear.

Safety is always important when operating an agricultural driveline. Safety objectives are achieved through simple sturdy components configured to produce a functional and durable assembly. The base cone is rigid to make the shield sturdy and robust. It is fitted with an eyelet for the restraint chain and a grease fitting for the lubrication of the shield bearing. The extruded plastic shield tubes are extremely sturdy components. The shield bearings connect the cone to the shield and to the inner yoke. A flexible cone is fitted onto the base cone to permit the outer yoke to move. Its length varies according to the end yoke, torque limiter or clutch attached to the driveline. Installing and removing driveline shields is a simple operation that can be done with commonly available tools. SAFETY SHIELDS Shield tubes can be cut to fit a specific driveline length, but the shield tubes should maintain sufficient overlap for all operating and transport conditions. Different types of joints, yokes, torque limiters and clutches have different shield requirements. The types of shield cones available are illustrated on the following pages. In compliance with international safety regulations, the outer cones of wide angle joints are mounted on the driveline. The shield is connected to the base cone and the standard shield bearing. The WA bearing is fitted to the centre housing of the wide angle joint. The metal ring stiffens the end of the shield in the case of 80 wide angle joints. 10 E & OE

Implements are designed to work for a certain lifetime, determined by a specific duty cycle associated with the application. Due to accidental overloads or unusual working conditions, loads may exceed what is considered normal. In such cases, the implement must absorb whatever power is available from the tractor. Generally, the tractor can supply more power than the implement can reliably absorb. Overloads, blockages, or sudden starts and stops of the implement all generate extremely high torque peaks. Eventually, these torque peaks may cause premature wear of the driveline and other implement components. A torque limiter or clutch installed on the driveline will provide protection against overloads and help prevent damage. They also allow more rational sizing of power transmission components. Different types of torque limiters and clutches are available. They should be selected according to the specific features of each implement and the particular duty cycle involved. For implements with high inertia (fly wheels, heavy rotors), torque peaks are possible during start-up and stopping. The Reverse loads caused by stopping these types of implements are eliminated by an overrunning clutch. The type of torque limiter must be selected according to the type of loads transmitted to the implement. The setting (Mt) is made according to the median torque transmitted (M) and to the torque limit of the system (M max for the driveline). When determining the setting, it is recommended to consider a tolerance of at least ±10% with respect to the nominal value. It is also suggested to consider factors of safety with respect to the strength of the entire power transmission system. Overrunning clutches are used to eliminate reverse torques generated by the inertial load of implements with large rotating masses such as flywheels. These reverse loads occur during deceleration or stopping the implement. Ratchet torque limiters and shear bolt limiters are used with implements with constant or alternating torque cycles, with possible overloads or torque peaks. The setting (Mt) of these torque limiters is usually 2 to 3 times the median torque M. Ratchet torque limiters should be used on drivelines operating at a speed of 700 RPM or less. Friction torque limiters are used on implements with alternating torque cycles and frequent overloads. They are able to protect the drive system from overloads and allow work to continue uninterrupted. Friction torque limiters with incorporated overrunning clutches are used on implements with high inertial (flywheels, rotors), subjected to torque peaks (especially during start up) and overloads. The setting of the friction torque limiters (Mt) is usually twice the median torque M. Standard settings for friction clutch torque limiters have been defined considering the pressure on the linings and the slipping velocity. Consequently, maximum suggested settings have been defined for each friction torque limiter model and size, for drivelines operating at 1000 RPM. TORQUE LIMITERS E & OE 15
OVERRUNNING CLUTCHES An overrunning clutch transmits rotary motion only in one direction. It is used to eliminate torque peaks generated by the inertia of implements with heavy rotating masses, such as rotors or flywheels during deceleration or stopping. A standard overrunning clutch is designed to operate with counter-clockwise rotation of the driveline in which it is installed. This is the typical rotation of an overrunning clutch installed on the implement side of a driveline connecting a tractor s rear mounted PTO (clockwise rotation viewed into the shaft) to the implement PIC (counter-clockwise rotation viewed into the shaft). RATCHET TORQUE LIMITERS TORQUE LIMITERS A ratchet torque limiter is a device that will interrupt the transmission of power in the event of a torque peak or overload that exceeds the setting. The torque limiter automatically re-engages after the cause of the overload is removed. Ratchet torque limiters are generally employed to protect implements subjected to constant or alternating torque from overloads. The setting is normally 2 to 3 times the median torque M. When the device is slipping, the user should promptly stop the PTO to avoid excessive wear. Ratchet torque limiters should be used only on drivelines operating at speeds less than 700 RPM. SHEAR BOLT TORQUE LIMITERS Shear bolt torque limiters are devices used to interrupt power transmission when the torque transmitted exceeds the settings. This interruption in power is caused by the shearing of a bolt. This bolt must be replaced before power can be restored. Use of shear bolt torque limiters is recommended to avoid damage to drivelines mounted in implements subjected to accidental overloads or torque peaks. The torque setting for shear bolt torque limiters is usually 2 to 3 times the median torque M and must never exceed the maximum torque of the drive line (M max ). Shear bolt torque limiters help reduce vibrations as they are designed to more evenly distribute their mass with respect to the axis of rotation. Shear bolt torque limiters are lubricated during assembly. No further lubrication is required for versions installed in size 1 and size 2 drivelines, therefore no grease fitting is provided. For other sizes it is recommended to lubricate at least once per season. The grease is necessary to lubricate the surfaces of the hub and yoke ensuring they rotate independently once the bolt has sheared. FRICTION TORQUE LIMITER Friction torque limiters, commonly referred to as friction clutches, are devices used to limit torque during overloads. During operation, the plates of the torque limiter slip against friction linings, transmitting torque at the clutch setting. The friction clutch is effective in limiting possible overloads and torque peaks generated during start-up in implements with high inertia. On these implements, a friction clutch is normally used with an overrunning clutch, able to eliminate reverse torque peaks during deceleration. The torque setting of friction clutches is generally twice the median torque M. Notes: Friction clutches may become hot. Do not touch!! Keep the area around the friction clutch clear of any flammable material, and avoid prolonged slipping that will generate excess heat and wear. 16 E & OE
