Weasler PTO Shafts

PTO Drive Shafts

Since the early days farmers have always sort ways to increase productivity and efficiency around the farm, one of the key areas to assist the farmer is incorporating machines into the daily life. The first machines relied on belt driven systems powered by steam engines but these did have their draw backs, the main one being that the machinery had to be stationary. However, over time the system was improved which allowed for traction engines to pull the implement and power it using the rotation of the engines wheels to power the implement, which was fine until the traction engine stopped moving. This called for a new system to use the tractors engine to power the implement without any limitations. The first marketable PTO system was introduced by International Harvester around the late 1910's which was closely followed by other leading manufacturers of the time.

Weasler PTO drive shafts are designed to meet specific requirements with the most economical design. Supplying a global market, Weasler can provide PTO drive shaft options in both North American and Metric. With these two styles Weasler has a complete offering of standard and wide angle PTO drive shafts, with many design options including telescoping, high speed, double telescoping.

HOW TO CHOOSE A PTO SHAFT

Regrettably all vehicle/implement connection dimensions are not all the same, otherwise it would be quite easy to select a common sized power take off shaft for any mechanical combination. So what information do you need to have to ensure that your PTO connects correctly to your tractor and implement? This may seem a bit daunting but it can be simplified in 3 easy steps;

Step 1 - Type of PTO Shaft

The first step in identifying a suitable replacement PTO assembly or component parts is to determine the "Series" (and "Type" where applicable) of the PTO shaft. The most common styles of PTO shafts are often referred to as "German" or "Italian" style.

You can identify the series/type of a PTO shaft by looking at the Shaft Profile of the inner and outer tubes and cross reference that with the dimensions of the universal joint (measurements AØ and A) used. We will select the required length of the shaft in a later step.

Step 2 - Tractor End

What type of connection is used for the tractor end? These connections can vary and may have a Quick Release mechanics', or be Wide Angle or have an Overrun Clutch.

Step 3 - Implement End attachment

What type of equipment will be attached at the over end will depend on the connection required, if you're unsure then check your documentation or contact us with your enquiry.
