I currently have a 303.5 with bracket and need a Pin-on Hydraulic Thumb attachment. What am I looking at for price and availability?

We suggest our 27" Universal Thumb Attachment for the Cat 303.5. This is a weld on thumb that comes with our universal brackets that you need. Simple weld the two mounting brackets on then pin the thumb and cylinder to the brackets with the hardened steel pins. I’ve emailed you a quote. Hope this helps.

Hey Reynolds ,
To answer your question some Cat 303.5 do come with a bracket for the thumb some don’t it really just depends but theres no guarantee. I would ask the dealer or person your purchasing it from.
I emailed you the quote and spec sheet for a 27" Built to Spec Pin-On Hydraulic Thumb for the Cat 303.5

I am buying a new cat 303.5 in the next 2 weeks. Can you send me the price also of a hydraulic thumb? All the new 303.5’s come with the attachment pin-point on the stick, right?

Glad to hear you’d like to purchase your second thumb attachment from www.MiniExcavatorThumbs.com, we do offer a 27" Pin-On Thumb attachment for the Cat 303.5. Typical these are 12" wide however that can vary. I have emailed you a quote with measuring instructions. Hope you like the Pin-On Style as much as the Weld On.

Buying another mini so I will need another one of your thumbs. New machine is a 2014 Cat 303.5. Do you have a thumb that pins on instead of welding? If so how wide is it? I run a 12" bucket.
