Thumbs are attachments that are welded to the back of the dipper stick of an excavator. Essentially, their function is to turn the excavator from a digging machine into a material handling machine, acting much like the thumb on your hand. We offer thumbs for all size excavators and backhoes. Excavator thumbs are offered in mechanical or hydraulic format.
A mechanical thumb is typically set into a specific position prior to beginning a project. Usually there are preset slots in which a pin is inserted in order to secure the thumb in a fixed position for the duration of a job. Hydraulic thumbs are much more versatile. The operator can manipulate the thumb to open and close with the bucket while picking up logs, debris, pipes, rocks, concrete and other material that would not ordinarily fit into the bucket.
At Solaris Attachments we provide you with a short form to ask for bucket measurements, number of teeth of the bucket, etc. so we can fabricate a thumb that fits your excavator and bucket perfectly. Our thumbs are 100% made in the USA with US Steel. Please fill out the form below to ask us for a quote or call (206) 290-0843.
