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.
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
For the production of the so-called GKN Walterscheid “Black Ball”, only top-quality materials are used. Therefore, Chrome-alloyed bearing steel is utilised as base material which then is refined in a specific heat treatment process and protected against rust with a cathodic dip-coating. During this manufacturing process, also the typical black colour of the high-quality coating develops. The new “Black Ball” is available via the GKN specialised trade with immediate effect.
provides sufficient space for Cat. 4 PTO drive shafts – New 389 millimetre spread – Interchangeable drawbar permits use of various hitch systems Against the backdrop of increasing tractor outputs and the growing use of Cat. 4 PTO drive shafts, GKN Walterscheid now offers a hitch frame series for the back of the tractor that has been optimised to suit these demands.Previous hitch frames were based on a spread of 310 to 336 millimetres. According to ISO 500, however, a clearance of 360 millimetres for the PTO is prescribed for Cat. 4 PTO drive shafts. This necessitates a spread of 390 millimetres. The KU346 hitch frame series offered by Walterscheid is one of the first solutions to meet these new standard specifications. Sufficient space is thus also available for attaching larger PTO drive shafts. This provides added safety and greater convenience when using wide-angle joints
Several different versions are available, e.g. the Type KU346L (long), the Type KU346KK (frame with permanently integrated ball) and the Type KU346F (piton-fix). A wide variety of hitch systems can be used with these models. Despite the greater width, the hitch frames of the KU346 series are capable of transmitting high vertical loads and complying with performance values without the inner slider becoming significantly heavier. This was primarily achieved by using forgings and forging technologies.
The new KU346 hitch frame series is available for tractors of the John Deere 7R series. Other hitch frame series with the new spread of 389 millimetres are additionally available for also converting older tractors.
