PTO Drive Shaft for Krone Round Balers

A PTO drive shaft is a mechanical device that transfers power from a power source, such as a tractor engine, to an external machine. PTO drive shafts are used in various applications, including agriculture, construction, and forestry.

A PTO drive shaft usually consists of two main parts: the drive end and the driven end. The driving end is connected to the power supply, and the driving end is connected to the external machine. The driving end and the driven end are connected by a flexible coupling, allowing misalignment between the two parts.

PTO drive shafts are available in a variety of sizes and configurations. The length of the PTO drive shaft depends on how much power it needs to transmit. The design of the PTO drive shaft depends on the type of power supply and the external machine it will be used with.

Agricultural PTO Drive Shaft Application:

You will see it being used if the device does not have its own engine. For example, you will often see power takeoff used in commercial vehicles and agricultural equipment. In fact, PTO shaft innovation mainly comes from the wisdom of farmers. The tractor engine is used as a PTO shaft to operate a jackhammer or other equipment.

Some other applications you see for using PTO shafts include:
(1) Snowblowers
(2) Hay baler
(3) Harvester
(4) Round bales
(5) Rotary tillers

What Is a PTO Shaft?

PTO drive shafts are the connection points for transferring the power from larger tractors to implements. PTO drive shafts are splined shafts sticking out of the tractor’s rear (compact utility tractors), splined recesses in the rear of the tractor (garden tractors), or splined shafts protruding from some point underneath the tractor. There are industry standards for the speed of these shafts.

The recessed PTO on garden tractors turns at 2,000 rpm. It uses the recessed design to prevent connecting an implement designed for the 540 rpm PTO used on compact utility tractors. Implements connect to the PTO shafts using a drive shaft with two or three universal joints to provide flexibility.

How to Measure the Parts of the PTO Drive Shaft?


Measuring the parts of the shaft correctly is essential for selecting the correct PTO series dimensions. Each product needs to be measured in a specific way to be consistent with the standard size. Follow these steps to ensure that the correct measurements are obtained and to order the parts required for the tractor.

1. Measuring axis
To measure the shaft, first make sure that the shaft is in the closed position, at which time the shaft is the smallest. Use a tape measure to record the length of the outside of each yoke. This measurement is the closing length. Use this measurement to find the correct series size for the tractor horsepower.
Make sure you also know if there are shear pins, clutches, or splined implement ends.
2. Measure the universal joint
When measuring the universal joint, measure the length from one end to the other. You also need to record the width of one end of the universal joint. Use these numbers to find the correct size of the universal joint.
3. Put them together
You need to make the above two measurements in order to find the PTO shaft parts suitable for your tractor and work normally. You can use the PTO yoke size chart to get the correct size, or use our convenient PTO series discovery tool.
