HT618 Gentec Universal Hydraulic excavator thumbs, 1500-3900 lbs excavators

Built-Tough

Introducing the HT618 Hydraulic Weld-On Thumb, built-tough for contractors, homeowners, and landscapers who demand reliability and durability. Our 6"x18" thumb is designed for machines under 3,900lbs and weighs just 38lbs. Constructed from 1/2" thick AR400 steel tines in a ladder frame construction with gussets, it's designed for increased strength and long-lasting durability. Trust in the HT618's double-sealed welded cylinder, ensuring increased reliability for years to come. Both the cylinder pins and main pin are greaseable, ensuring smooth operation and reduced wear.

Superior Geometry

Experience the superior geometry of the HT618 Hydraulic Weld-On Thumb. With a maximum extension angle of 140 degrees, it outperforms the competition, offering greater versatility and ease of use. When fully retracted, the tines only extend 7.5" away from the edge of the excavator stick, ensuring minimal stowed dimensions and preventing interference when digging. The thumb's geometry is designed to mechanically stop the tine assembly from causing cylinder lock-out when retracted, protecting your equipment and guaranteeing a smooth operation.

      MEASUREMENTS

      Please follow these instructions when measuring. You want your "stick to tip" measurement to be as close to the thumb tine length as possible. GENTEC's mounting plates are very narrow so typically there is no problems with the mounting plate (exception is the very smallest class of mini excavator)

      INSTALLATION

      Please follow these instructions when installing your thumb.
