What bucket fits a Cat 305?

The Cat 305 uses 40mm pins with 155-160mm pin centres on most models. We stock GP buckets, mud buckets, and trenching buckets from 300mm to 1200mm width. Send us your serial number and we'll confirm the exact fit.

Do Cat attachments fit other brands?

Cat pin configurations are specific to Caterpillar machines. While some sizes overlap with other brands, we recommend ordering attachments matched to your exact machine to avoid fitment issues.

Can I use a Cat quick coupler with your attachments?

Yes. We can supply attachments with Cat quick coupler brackets or standard pin-on configuration. Specify your coupler type when ordering.

How do Cat and Kubota pin sizes compare?

Cat and Kubota use different pin configurations on similar sized machines. A 5 tonne Cat and 5 tonne Kubota need different attachments. We stock both and will match the correct one to your machine.
