Having a thumb on your excavator, will essentially make two machines out of one. In addition to being able to dig and all the features a trackhoe offers, once a thumb is added, that same machine can now grab, sort and load anything from rocks and scrap to trees and pipes.  

What Is The Difference Between Manual & Hydraulic Thumbs?

 

There are two different types of thumbs available: Manual & Hydraulic. A manual thumb is more common, and a less expensive option. The thumb is held in position using a pin & solid arm. The adjustment of the thumb to bucket angle, is changed by unpinning the arm & allowing the arm to slide to the desired position, then being re-pinned. A hydraulic thumb requires the machine already be plumbed with auxiliary hydraulic lines & have a foot pedal or switch to control the thumb. A hydraulic cylinder allows for on the fly adjustment of the thumb's proximity to the bucket, without ever leaving the cab.

​There are a few things required when deciding which size of thumb will fit on your trackhoe or backhoe. Thumbs are sized by length of the tines, also known as fingers, & the bracket length. A good estimate of size is based on the weight of your machine, however the most accurate way to choose the correct size of thumb is by measuring your stick width, as well as the distance from the teeth of the bucket to the stick, when sitting at a 90 degree angle.

Our thumbs are built with universal fit design for a variety of brands including John Deere, Caterpillar, Komatsu, Kobelco, Volvo, XCMG, Hyundai, JCB, Link Belt, Bobcat, Hitachi, Sunward, Kubota, Case & most others. They are manufactured to heavy duty specs, weld-on ready & have serrated edges for better gripping. The proximity of the manual thumb is adjustable by moving the placement of the arm & pin, while the hydraulic thumbs utilizes your machine's auxiliary hydraulics and foot pedal or thumb switch. If the machine is being used to grab materials more often, the operator may choose to have the thumb angled closer in proximity to the bucket for less bucket swing. In the opposite situation where digging is more of a necessity than grabbing, the thumb can be moved to a larger degree of angle, away from the bucket or even completely positioned against the stick or fully removed if it is not being required during certain dirt digging work. 

I35 Equipment offer a wide range of new thumbs which include the brackets and pins, as used thumbs are rare and often do not includes the brackets, as they were left welded on to the machine.
