In the last years, ball couplings 80 have been on the rise in the tractor market. This fact poses a challenge for the inspection of hitch mechanisms, e.g. in the mandatory yearly general inspections („Hauptuntersuchung“). Presenting tractors with assembled hitch mechanism, but without any coupled implement or trailers with ball system, is common practice.
Determining the exact condition of the chain guide plays a crucial role - it constitutes the central locking device for the connection between tractor and trailer. A safe condition monitoring of a chain guide on a ball80 proves impossible without a coupled calotte. A new chain guide, who would be required for comparison with the existing one, is often not available to the inspector due to the variety of available models.
Designed specifically for this purpose, GKN Walterscheid now offers its new test calotte PK80. It is built for use on all current ball80 systems. Due to its semi-open design, it can even be assembled on a locked chain guide. After preset the clearance specified by the manufacturer, the chain guide should be moved vertically to determine whether the adjustment range on the adjustment screw still suffices.
If this is not the case, the chain guide has reached its wear limit and must be replaced. Wear and tear on the adjust pin mount can also be checked easily as well as chain guide deformations.
„Inspectors have always wished for a professional way to check existing hitches on tractors. Many employees of testing agencies like TÜV or Dekra who attended our training courses have called our attention to this“, says Maik Lehmann, instructor for tractor attachment systems at GKN Walterscheid.
As an interested workshop, expert or testing agency, you can find more information about our new test calotte here.
Our new test calotte is available now through our retailers (Order no. 8005483)

In agricultural operations, transmission of power via drive shafts continues to be one of the most important and efficient drive concepts. Walterscheid produced its first agricultural drive shaft at the beginning of the 1950s, and thanks to innovative developments, quickly achieved a global reputation as a leading supplier and easy recognition of its yellow coloured driveshafts. Over 65 years later, GKN Walterscheid engineers now fundamentally advanced the “yellow drive shaft”, thus achieving new levels of performance, safety and functionality. For this purpose, all major functional areas and components of the drive shaft were completely re-engineered. This process resulted in the new ULTRA.PLUS system that can be utilised in almost all Walterscheid driveshaft products.
“More than 100 newly developed or re-engineered components will be installed in our Walterscheid driveshafts in the future. The sum of numerous detailed developments provides for a markedly improved overall performance”, reports Wolfgang Adamek, responsible Head of Construction and Development for the new ULTRA.PLUS system. “In addition, we can offer an optimally customised drive shaft for each and every application – and this is not only true with regard to the growing requirements of agricultural equipment manufacturers. With the ULTRA.PLUS system, also the end customer will find the drive shaft which is optimally adapted to his operation”, says Adamek. The ULTRA.PLUS system will be stepwise introduced for all series starting in mid-October 2017.
The new universal joints are one example of technological enhancements which will be applied in Walterscheid driveshafts in the future. The combination of the proven turquoise multi-lip seal, precision manufacturing and innovative lubricants ensure marked progress. The ULTRA.PLUS system now offers a doubling of the joint’s service life, and a clear increase in operating reliability, whilst maintenance efforts and wear are considerably reduced. In addition, environmental friendliness is improved, not in the least due to the markedly reduced loss of lubricant. Thanks to the proven cap bottom lubrication, greasing has also become significantly easier.
For the new profiled guard tube with the “ST” labelling, both protective halves are connected in such a way as to make one holding chain obsolete. In combination with complete protection, no holding chain is required. Easy handling, reduced wear, stability, and compatibility with today’s SD/SC safety guards provide convincing arguments for the new guard concept. This also includes the new Walterscheid Premium Guard Cones which considerably simplify mounting/dismounting and maintenance of drive shafts and clutches. The implement guard cones are manufactured from high-quality materials, can be opened and removed in a few quick steps and offer an automatic 360° single click locking. These Premium Guard Cones have low requirements with regards to available space and feature a universal hole pattern for almost all applications.
The new compact 50° wide-angle joint P450 is the ideal supplement to the proven Walterscheid wide angle joints. It was specifically designed for wide constant-angle applications, and can be used for all applications with a 50-degree maximum shaft angle. With its innovative centring system, the P450 joint is well suited for high speeds, rotates smoothly and is zero-maintenance thanks to the fully sealed centring unit. it can be combined with standard joints, wide-angle joints as well as overload and overrunning clutches to cover a wide range of applications.
With the newly developed friction clutches K90TF and K90/4TF, local agricultural machinery businesses can now also take care of maintaining and adjusting the clutches, thus extending the service life of remaining friction linings. In addition to secure venting and easy maintenance thanks to the simple exchange of linings, the characteristics of the new diaphragm springs of these clutches automatically compensate for wear in the lining, thus ensuring an excellent constancy of torque and high operating reliability. Thanks to an optimised bearing concept, the new cam-type cut-out clutch K68/EK68 achieves significantly quieter running. The lubricant volume has been increased and the seal improved. As a consequence, this model’s strength are a markedly reduced maintenance effort, reduced risk of dirt accumulation, and lower grease losses as well as a significant increase of service life and operating reliability.

As an option, the proven Walterscheid profile tubes can be equipped with the new lubrication system for profile tubes with immediate effect. Good accessibility of the grease nipple, homogeneous grease distribution via only one grease nipple as well as secure lubrication regardless of length and position do not only ensure a longer service life and higher performance but also provide for easier handling
The new GKN Walterscheid hydraulic top link with integrated shock absorber provides markedly higher driving comfort and safety. For this purpose, GKN Walterscheid engineers developed an innovative shock absorber mechanism which is directly integrated into the hydraulic cylinder and hence does not require any additional space. During operation, the new hydraulic top link allows for considerable extra comfort. The desired absorption rate can be adjusted to individual tractor-implement combinations by professional workshops.
he new hydraulic top links with shock absorber are compatible and interchangeable with existing standard top links. They can be installed without additional components. In comparison to standard hydraulic top links, the installation does not require any special parts or additional space. The concept allows for a secure operating position without continuous actuation of the check valve. Impact loads caused by “bouncing implements” are isolated from the tractor. This results in a markedly improved driving performance due to optimised ground contact of the front axle. As a consequence, safety is improved in all driving situations, there is more grip, and on the whole, productivity is increased. In addition to improved driving comfort, practical experiences also give evidence of clearly reduced wear of components. The new hydraulic top link will be available in all usual sizes via the GKN specialist trade shortly.
