Built-Tough

Introducing the HT1850 Hydraulic Weld-On Thumb by Gentec – built tough for large contractors. This 18" wide and 50" long thumb is designed for machines between 24,000lbs and 39,000lbs and weighs 600lbs. Constructed with four 1" thick AR400 Steel Tines in a ladder frame layout and reinforced with gussets, our HT1850 thumb is designed for increased strength and long-lasting durability. The double-sealed welded cylinder enhances reliability, and spherical bushings at the top of the cylinder protect it from side loading. The cylinder comes with a hydraulic cushion at the top of the stroke to protect it during retraction and has both hydraulic ports located at the top so your hydraulic hoses are safe and out of the way. Additionally, both cylinder pins and the thumb main pin are greaseable for easy maintenance. The main pin and main bushings are hardened for added durability.

Superior Geometry

Experience superior geometry with the HT1850. The thumb boasts a maximum extension angle of 115 degrees. Designed to minimize stowed dimensions, when fully retracted, the tines only extend 18" away from the edge of the excavator stick – meaning it won't get in your way when digging. The backplate measures 67 3/8”, and the hydraulic cylinder is included. The port size on the cylinders is larger to allow for faster cycling.

** PLEASE CHECK YOUR MEASUREMENTS BEFORE ORDERING. (LOOK UNDER "BIG DAVE" TAB FOR INSTRUCTIONS) CALL WITH ANY QUESTIONS OR IF YOU NEED HELP THE THUMBS CAN BE TRICKY TO ORDER CORRECT.

⚠ Pro Tip! If your excavator is equipped with a Pin-Grabber quick coupler, choose a longer thumb to ensure a suitable fit with your bucket.

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.
