Understanding Different Types of Tractor PTO Shaft
Tractors are essential for farming and agricultural practices. These machines are powered by PTO shafts or Power Take-Off shafts. The PTO shaft transfers power to the attached implement, such as a mower or plow, to perform agricultural tasks. Here, we elaborate the different tractor pto shaft types that exist in the market.
Standard PTO Shaft
The standard PTO shaft is the most widely used tractor PTO shafts type. It is designed for tractors with PTO speeds of 540 revolutions per minute (RPM). The shaft is typically 1⅜ inch in diameter, and its tractor end has six splines. The implement end also has six splines, but it may be fixed or removable.
Constant Velocity PTO Shaft
The Constant Velocity PTO Shaft is designed to eliminate vibration and minimize power losses. It is suitable for larger tractors working at speeds above 540 RPM. The shaft's tractor end has six splines, while the implement end has six or eight splines, depending on the implement.
Collar Shift PTO Shaft
The Collar Shift PTO Shaft is designed with a collar shift system, consisting of two yokes and a telescopic splined tube. It is designed to allow the implement to be moved quickly from side to side, saving time and labor. It is suitable for agricultural implements such as mowers, balers, and spreaders.
Slip Clutch PTO Shaft
The Slip Clutch PTO Shaft is designed with a mechanical device that engages when the implement encounters a sudden resistance or overload. It is ideal for use in uneven terrain and on rocky soil. It has the same dimensions as the standard PTO shaft and can be used with implements such as mowers and shredders.
Shear Bolt PTO Shaft
The Shear Bolt PTO Shaft is designed to use a shear bolt that protects the equipment from damage when an overload is encountered. The bolt breaks before the PTO shaft or the equipment is damaged. It is suitable for use in various agricultural implements, including spreaders, tillers, and sprayers.
Hydraulic PTO Shaft
The Hydraulic PTO Shaft is designed to power hydraulic pumps used in tractors. It operates at 540 RPM and has a standard 1⅜ inch diameter and six splines on the tractor end. It is designed to work on tractors with hydraulic systems powered by PTO shafts.
Telescoping PTO Shaft
The Telescoping PTO Shaft is designed to work on tractors with varying distance between the PTO and the implement. It is designed with a telescopic tube that can be adjusted to accommodate the distance. It is suitable for use with various agricultural implements, including shredders, mowers, and tillers.
Overrunning Clutch PTO Shaft
The Overrunning Clutch PTO Shaft is designed with an overrunning clutch that prevents the implement from spinning the PTO shaft when decelerating. It is suitable for use in implements such as post hole diggers, sprayers, and cultivators.
Single and Double Universal Joint PTO Shaft
The Single and Double Universal Joint PTO Shaft is designed with universal joints that can be oriented at different angles between the PTO shaft and the implement. It is suitable for use with mowers, sprayers, and tillers.
Conclusion
Choosing the right PTO shaft is essential for the efficient operation of the tractor. When selecting a PTO shaft for your tractor, you should consider its speed, power take-off horsepower, and torque requirements. With our detailed guide, you should have a better understanding of the different tractor PTO shaft types available in the market and their respective applications.
