Built-Tough
The MT3272 Mechanical Weld-On Thumb boasts a 32″ width and 72″ length, and is comprised of four 2″ thick AR400 Steel Tines. These tines are arranged in a ladder frame layout and reinforced with gussets, guaranteeing enhanced strength and lasting durability. Designed to fit machines weighing between 65,000 and 100,000 lbs, the Gentec MT3272 itself weighs 1,750 lbs. Its A-Frame link construction greatly improves torsional rigidity, making it a dependable choice for farmers and demolition contractors who require top performance and longevity. Additionally, the main pin and bushings are hardened for increased durability.
Superior Geometry
Offering exceptional versatility, the MT3272 Mechanical Weld-On Thumb features three-position adjustability at angles of 90, 99, and 112 degrees. When not in use, the thumb easily stows away, occupying only 71″ of vertical space on the excavator stick and extending a mere 19″ off the stick when stowed. This ensures it won’t obstruct your digging operations. With no loose parts when stowed, you can trust that your equipment remains secure and ready for use whenever needed.

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.
