Paladin Classic Series
Main pin mounting
140–350 lbs
Overview
This Paladin Classic Series hydraulic thumb for excavator mounts on the main pin and turns a digging bucket into a grab. It is offered for Coupler Length, STD Length machine classes, weighing 140–350 lbs. A main-pin thumb pivots on the same pin as the bucket, so the two close against each other — that geometry is what lets you pick up material a bucket alone would push around.
Key Features of This Paladin Hydraulic Thumb For Excavator
- Main pin mounting — the thumb shares the bucket pin, so bucket and thumb close on each other.
- Hydraulically operated, so the grip is adjustable through the full arc rather than fixed.
- 140–350 lbs depending on machine class and length.
- Classic Series construction from Paladin.
- Often searched for as a hydraulic thumb for mini excavator — same product, different trade name.
- Sometimes listed as a mini excavator hydraulic thumb, which is the term some regions use.
- Buyers also ask for this as an excavator hydraulic thumb.
- Catalogued elsewhere as a hydraulic excavator thumb — the naming varies more than the product does.
Why Choose This Attachment
- A thumb is the cheapest way to double what an excavator can do. The machine already has the bucket and the boom; the thumb adds the ability to hold rather than only scoop.
- Main pin versus weld-on is a real choice. Main pin shares the bucket pivot and closes cleanly against the bucket. Weld-on mounts further up the stick and gives more clamping range but less precision.
- Match the thumb to the bucket, not just the machine. A thumb sized for a wide bucket will not close properly on a narrow trenching bucket — check the pairing you actually run.

Main Pin Thumb or Weld-On?
Thumbs differ mainly in where they mount, and that decides how they close.
| Type | Mounting | Trade-off |
|---|---|---|
| Main pin (this) | Shares the bucket pivot pin | Closes precisely against the bucket; simpler to fit |
| Weld-on | Welded to the stick | More clamping range; permanent and needs a competent welder |
| Progressive link | Linkage on the stick | Widest range; most complex and most expensive |
If you need to grip rather than scoop on a wheel loader instead, the Class 600 grapple bucket is the equivalent tool.
Which Machines Fit This Hydraulic Thumb For Excavator?
This thumb fits the machine classes listed above and mounts on the main bucket pin. It requires an auxiliary hydraulic circuit — the thumb is powered. At 140–350 lbs it is light relative to the machine, but it does reduce what you can lift at full reach.
| Requirement | Specification |
|---|---|
| Carrier | Excavator — see machine classes above |
| Mounting | Main bucket pin |
| Attachment weight | 140–350 lbs |
| Hydraulics | Auxiliary circuit required |

Hydraulic Thumb For Excavator Questions, Answered
What is a main pin thumb?
One that pivots on the same pin as the bucket, so the two close directly against each other. It is the simplest thumb to fit and the most precise for picking up individual objects.
Will it work with any bucket?
It closes best against the bucket it was sized for. A thumb matched to a wide bucket will not meet a narrow trenching bucket cleanly — check the pairing you actually run.
Do I need extra hydraulics?
Yes, an auxiliary circuit. The thumb is hydraulically operated, which is what lets you adjust grip through the arc rather than having a fixed stop.
Can I leave it on permanently?
Yes, though it adds weight at the end of the stick and slightly reduces what you can lift at full reach. Many operators leave it fitted and simply park it back when digging.
Is a hydraulic thumb better than a mechanical one?
For anything you pick up repeatedly, yes — a mechanical thumb has fixed positions. A hydraulic one holds whatever shape the load is.
How much lift capacity does a thumb cost me?
Its own weight, at the far end of the stick, which is where weight hurts most. On a small machine that is worth checking against your rated capacity at full reach rather than at the boom.
What length should I choose?
Long enough to close on the material you handle most. A thumb that is too short leaves a gap against the bucket on large objects; too long and it fouls the bucket on small ones.
Does it need maintenance?
Grease the pivot and check the cylinder rod and hoses where they run along the stick. Thumbs take impact loading that a bucket does not, so the pin is the thing to watch.
Is this the same as a main pin thumb?
Yes — main pin thumb, excavator thumb attachment, mini excavator thumb kit all describe this product. Terminology varies by region and trade.
