Fits:

• Hitachi ZX450
• Hitachi ZX470
• Hitachi ZX490

 Includes:

• 4 Buckets
• Quick Coupler
• Progressive Link Thumb
• Thumb Cylinder & Cylinder Mount
• Mounting Pins

Designed to fit many different models... the inside space of the coupler is 10.3mm, so if your model has a stick width of 10mm or less the bucket set will go on easily, If it is a little over, some filing/sanding might be necessary but that is easy enough to do.
