HLA Attachments - Regular Duty JD 400/500 Series Quick Fit Plate - Loader Quick-Attach Adapter [LA-BOQF10JD440540]

HLA Attachments BOQF10JD440540 Regular Duty JD 400/500 Series Quick Fit Plate is a loader quick-attach adapter designed to let compatible John Deere loaders use universal skid-steer quick-attach attachments. Combining John Deere JD440 and JD540 loader-side interfaces with HLA’s universal skid-steer attachment plate, it provides a practical way to expand attachment options for compact to midsize loaders. This manual-locking adapter has a rated capacity of 3,500 lb and uses a spring-loaded over-centre lever lock to secure compatible attachments.

Expand Your Loader’s Attachment Options

The BOQF10JD440540 converts selected John Deere 400- and 500-series quick-attach loader carriers to the widely used universal skid-steer quick-attach interface. Once installed on a compatible loader, the adapter enables the use of universal skid-steer attachments without replacing the loader’s existing carrier.

This regular-duty configuration is intended for compact to midsize loaders. Its 3,500 lb rated capacity supports a broad range of compatible loader attachments while keeping the adapter at an approximate weight of 135 lb (61 kg). The design is suited to operators who want greater flexibility when selecting or sharing attachments across equipment fitted with a universal skid-steer interface.

Manual Spring-Loaded Locking System

A spring-loaded over-centre lever lock provides manual attachment retention. This straightforward locking configuration allows the operator to secure a universal skid-steer attachment to the adapter using the integrated lever mechanism. As with any quick-attach connection, the attachment and locking mechanism should be checked to confirm complete engagement before operation.
