What Are the Differences Between a Standard and a Constant Velocity (CV) Agricultural PTO Shaft?

PTO shafts are an essential component of , allowing power to be transferred from the tractor to the connected implement. There are two types of PTO shafts – standard and constant velocity (CV) agricultural , each with its own unique characteristics and benefits.

Standard Agricultural PTO Shaft

A standard agricultural PTO shaft is the more traditional of the two types of PTO shafts. It's a simple, cost-effective design that has been in use for many years. It consists of two yoke assemblies connected by a telescoping shaft. The telescoping action allows for the length of the shaft to be adjusted to suit different implements.

Constant Velocity (CV) Agricultural PTO Shaft

A constant velocity (CV) agricultural PTO shaft, on the other hand, is a more modern design that has been developed to address some of the limitations of the standard PTO shaft. It consists of a telescoping shaft with two that are designed to maintain a constant velocity even when the angle of the shaft changes.

Specific Agricultural Machinery and Operating Environments

Both types of agricultural PTO shafts are used with a wide range of agricultural machinery, including rotary mowers, hay balers, and tillers. The choice of which type of PTO shaft to use will depend on a range of factors, including the type of implement being used, the power requirements of the implement, and the operating environment.

The Advantages of PTO Shafts

  • Efficient power transfer from tractor to implement
  • Easy to install and remove
  • Cost-effective
  • Multiple sizes available
  • Increased safety by keeping the operator away from moving parts of the machinery

Maintenance and Replacement of PTO Shafts

Maintenance of PTO shafts is essential to ensure they function correctly and safely. Regular maintenance should include cleaning, greasing, and inspection of the shaft and associated parts. Replacement of a PTO shaft should only be performed by a qualified technician. The following are the basic steps for replacing a PTO shaft:

  1. Securely block the machinery to prevent movement
  2. Remove the old PTO shaft from the tractor and implement
  3. Install the new PTO shaft, ensuring it's the correct size and type for the implement and tractor
  4. Test the new PTO shaft to ensure it's functioning correctly

PTO Shafts and Agricultural Gearboxes

PTO shafts and agricultural gearboxes work together to transfer power from the tractor to the implement, making them integral components of a range of agricultural machinery. Agricultural gearboxes are used to change the speed and direction of the power from the PTO shaft to suit the requirements of the implement. At WLY Transmission, we offer high-quality agricultural PTO gearboxes for sale, ensuring our customers have access to all the components they need for their agricultural machinery.
