Wide angle PTO Drive shafts
The first constant velocity joints were introduced into agriculture in the 1970s to increase the efficiency of towed machines, reducing or eliminating the irregular movement generated by Cardan shafts during the turning phase.
The need for large turning angles involves wide movements of the centring disc within the constant velocity joint, and significant openings in the central body, leading to leaks and risks of contamination of lubricating grease.
Up to now, the shafts equipped with constant velocity joints have offered better handling and turning speed with regards to equal angle Cardan shafts, but they also required frequent lubrication and a large amount of lubricating grease.
The 80° constant velocity joints of the Global drive shafts overcome these issues given that they require weekly lubrication (every 50 hours) and a smaller amount of grease with regards to traditional constant velocity joints.
