The hydraulic quick hitch is a popular attachment for excavators. It is known for its ability to increase productivity and reduce downtime, making it a valuable investment. This type of quick coupler is connected to the excavator's hydraulic lines, allowing the operator to control the hitch from inside the cab using a switch. The locking latches are controlled by hydraulic components, which are powered by the internal spring. When the switch is activated, the latch closes to secure the attachment pin in place. To disconnect the attachments, the same process is followed to unlock the coupler.

The biggest benefit of the hydraulic quick hitch is that it allows the operator to connect and disconnect buckets and attachments from inside the cab. Not only does this reduce the amount of time it takes to change your attachments, but it also increases the amount of time you can spend working, to get your projects completed faster. Not only is this beneficial to single machine operators, but it's also a huge benefit to plant operators as their customers are going to have a smoother operating experience which will likely bring them back for any future needs. The other huge benefit is that hydraulic hitches have the ability to pick up a wider variety of pin sizes due to the travelling latch. This means that you will be able to pick up buckets and attachments within a pin range, rather than one specific pin size, making your buckets and attachments more versatile across a range of different machines. This is great if you own a rental company with different excavators as it allows you to mix and match your buckets and attachments.
