Excavator Attachment Guide

Getting the right information.

Key Measurements

Most modern excavators now have a hydraulic hitch to make changing the buckets & attachments much easier. Some smaller excavators these days will still have a manual hitch but the concept will be the same. When you order an excavator attachment there will be 3 main measurements that will need to be provided to ensure the correct head bracket is supplied.

The key measurements are:
-Pin Diameter
-Pin Centre to Centre
-Distance between the ears

These 3 key measurements are essential to ensure that your excavator hitch will accept the head bracket on the attachment.

Hydraulic Hoses

Other than mechanical attachments such as buckets & rippers, most excavator attachments will require the hydraulic power of the excavator. As a result we will need to connect the excavator attachment with the excavator through a series of hydraulic fittings.

Most attachments will only required 2 fittings a pressure & return line. Some attachments will require a case drain.

The 3 most common types of hydraulic fittings are:
-Flat Face Quick Couplers
-BSP (British Standard Pipe)
-JIC (Joint Industry Council)

We will also make notable mention to the ball bearing quick coupler which is more common in agriculture.
