Extended Product Information
FAQs
Does this thumb come with the hydraulic hoses?
The product includes the primary cylinder, but you will need to source hoses and fittings that match your specific machine's hydraulic port configuration.
Can I bolt this on instead of welding?
Due to the extreme forces involved in excavation, welding is the only safe and recommended method for attaching the mounting bracket to the dipper stick.
What is the maximum weight this thumb can lift?
The weight capacity is primarily determined by your excavator's hydraulic pressure and the tipping load of your machine, rather than the thumb itself.
Is the tooth plate replaceable?
Yes, the design includes adjustable and removable components to accommodate different materials and simplify long-term maintenance.
Will this fit any brand of excavator?
While it is designed for standard backhoe and excavator sizes, you must verify that your machine has sufficient space on the dipper stick to mount the 45.72 cm assembly.
Troubleshooting
Thumb movement is sluggish or non-responsive.
Check the hydraulic fluid levels in your excavator and ensure the quick-connect fittings are fully seated.
The thumb vibrates or feels loose during operation.
Check the pivot pin bolt for proper tension and ensure no debris is wedged in the hinge mechanism.
Hydraulic fluid leaking around the cylinder shaft.
Inspect the cylinder seals for damage and contact a hydraulic specialist to install a replacement seal kit.

Setup, Compatibility & Care
Installation of the VEVOR Hydraulic Backhoe Thumb requires welding the mounting bracket directly to the dipper stick of your machine. Before installation, ensure your excavator has the necessary auxiliary hydraulic circuit to power the cylinder. We recommend having a certified welder perform the installation to ensure the structural integrity of the mounting point. For care, regularly check the cylinder seals for leaks, apply grease to the pivot pins at the start of each workday, and inspect the tooth plate welds periodically for any signs of stress fatigue.
