PowerBrute Hydraulic Thumb - Amulet

📘 Overview

A weld on excavator thumb that fits almost anything: the Amulet PowerBrute is a low-cost, universally fitting hydraulic thumb suiting most makes and models of backhoe and excavator, old and new. Its base plate welds to your boom and it runs an independent main pin, separate from the bucket pin, so bucket changes never require removing the thumb. Amulet builds seven models covering machines from 2,500 lb to 100,000 lb, in two connector configurations: the standard weld-on base plate build, and a coupler pin-on build for machines running a quick coupler. Narrow-bodied and true-universal, it works with virtually any bucket the host machine will accept.

Specify your excavator make, model and year and your connector configuration when ordering.

It ships as a complete excavator thumb kit — thumb, full-length base plate with mount stop and remote hinge pin, and cushioned cylinder. On the small classes it is a mini excavator hydraulic thumb at 60 lb, and the same design scales to 1,300 lb for 50-ton machines, so one excavator thumb attachment covers a mixed fleet. If you want a model-specific hydraulic thumb for excavator work with tines that mesh into your bucket, Amulet builds the PowerClamp instead.

🔩 PowerBrute Weld On Excavator Thumb — Connector Configurations

The PowerBrute is offered in several builds, and the option list on this page reflects what is available for your machine class. Getting this right matters: it determines how the thumb attaches to your machine.

Amulet’s literature is explicit on why the remote main pin matters: it works great with all buckets and quick couplers, and makes changing buckets and other attachments a breeze — no need to remove the thumb. That is the practical case for the PowerBrute over a shared-pin thumb.

The weld-on base plate and coupler pin-on builds are the two configurations Amulet lists across every machine class in its current price book. The thumb-ready OEM cylinder mount and Case & John Deere builds are machine-specific and are not in that price book — if you select either, we confirm the build with Amulet against your make, model and year before the order is processed.

🔧 Amulet PowerBrute Key Features

• Universal fit — fits most makes and models of backhoe and excavator, both old and new, rather than being built for one machine.
• Independent, remote main pin — the thumb pivots on its own pin, not the bucket pin, so you change buckets without removing the thumb and put no extra stress on the bucket pin.
• Full-length weld-on base plate on most models, including the mount stop and the remote main hinge pin. Easy installation.
• Universal two-tine design with a narrow body, so it works with virtually any bucket the host machine will accept.
• High-strength alloy that maximises performance while minimising the extra weight added to the dipper stick.
• Open back design for improved visibility to the work.
• Large-diameter hardened pins and bushings throughout, with grease zerks on the main pin and hydraulic cylinder.
• Cushioned cylinder with heat-treated pins.
• Stores hydraulically tight against the dipper stick when not in use.
• Thumb curls independent of the bucket — useful in demolition, rock placement and land clearing where you want to work the thumb alone.
• 2-year warranty, 100% made in the USA at Amulet’s plant in Rathdrum, Idaho.

⭐ Why the PowerBrute Is Amulet’s Most Popular Thumb

• Low cost, universal fit. It is the answer when a model-specific thumb costs more than the job justifies, or when you need one thumb design across a mixed fleet.
• Rental fleets run it for a reason. No shared pin means no machine-specific fitting, and low maintenance means it comes back from hire without a service bill.
• Bucket changes stay fast. With the main pin independent, swapping buckets is unaffected by the thumb being fitted — on a shared-pin thumb it is not.
• Less weight where it hurts. High-strength alloy keeps the mass down at the end of the stick, where every pound costs you lift capacity.
• It sees what it is doing. The open back design means you can actually watch the material you are gripping.
• It fits old machines. A universal weld-on design does not care whether your excavator is current-model or twenty years old — if you want an excavator with thumb capability on a machine nobody builds parts for any more, this is usually the answer.

📊 PowerBrute Hydraulic Thumb Models by Weight Class

Both connector configurations are built across every class. Thumb weight is the range across the two builds — the coupler build is the heavier. Weight determines what the thumb costs you in lift capacity and what the freight costs at checkout.

🚜 PowerBrute Machine Compatibility

The PowerBrute is a universal weld-on hydraulic thumb. The base plate welds to your boom, so fitment is determined by machine weight class rather than by an exact model match — and by whether your machine runs a quick coupler, which decides between the two connector builds. Find your machine below to identify its weight class, then select that class and your configuration from the options above.

Fits machines from Bobcat, Bradco, Case, Caterpillar, Daewoo/Doosan/Develon, Ford, Gehl, Hitachi, Hyundai, IHI, Ingersoll-Rand, JCB, John Deere, Kobelco, Komatsu, Kubota, Link-Belt, Liu Gong, Mustang, New Holland, Samsung, Sany, Takeuchi, Terex, Thomas, Volvo, Wacker Neuson, Woods, XCMG, Yanmar — 30 manufacturers in total.

Machine list from the 2026 Amulet price book, filtered to the weight classes this product covers. Not every machine listed accepts every Amulet product. The PowerBrute requires a two-way hydraulic circuit on the stick — note that two hoses running up the stick does not always mean two-way hydraulics. If your machine is not listed, or you are not sure which class it falls into, send us your make, model and year on chat or at support@eskidsteer.com and we will confirm it.

❓ PowerBrute — Common Questions

🔗 What the PowerBrute Works With

• Swap your bucket for the Amulet HoeMate Multi-Tine Rake and the thumb closes onto an open-tine rake — a grapple for a fraction of a dedicated one.
• The Amulet PowerClamp Hydraulic Thumb is the model-specific alternative, sharing the bucket pin for maximum meshing grip.
• The Amulet B.R.U.T. Rigid Thumb is the non-hydraulic option if your machine has no circuit to spare.
• Choose the coupler pin-on build if your machine runs a quick coupler — the Amulet Mini-Hitch Quick Coupler is Amulet's mechanical option.
