Product & applications
About the excavator ripper
A single-shank excavator attachment for loosening hard soil, compacted ground and suitable soft rock before excavation.
Features & benefits
Reinforced structural design
The shank and mounting structure transmit excavator digging force into the ground.
Adjustable tooth arrangement
An adjustable tooth arrangement accommodates different soil conditions.
Simple maintenance
The ripper uses a ground-engaging mechanical structure without a powered cutting or vibrating mechanism.
Typical applications
- Hard soil and clayLoosen hardpan, compacted earth and clay before excavation and loading.
- Soft-rock excavationBreak up suitable soft rock using the shank and tooth before a bucket removes the loosened material.
- Land reclamation and site preparationPrepare ground on construction, agricultural and mining sites. Confirm formation hardness; a ripper is not a universal substitute for a hydraulic breaker.

Installation requirements
Confirm the attachment fits your excavator
Before ordering, send the machine identification and the connection, power and working information relevant to this product.
- D1 / D2
- Both pin diameters
- C
- Pin centre distance
- W
- Clear mounting width
Excavator and attachment weight
Use the selected model carrier range and check the actual machine lifting and digging limits.
Pin-on mounting
Confirm both pin diameters, pin centres and the clear arm width against the selected model.
Ground conditions
Describe soil hardness, rock conditions and buried obstructions. A passive ripper is not a hydraulic hammer.
Working clearance
Check the tooth path and shank clearance throughout the excavator linkage movement.
Product questions
Excavator ripper questions
Is this ripper hydraulically powered?
The referenced single-shank ripper is a passive attachment. The excavator linkage provides the working force.
Can it replace a bucket?
It loosens ground; use a bucket to excavate and load the loosened material.
Can I choose using excavator weight alone?
No. Also confirm the actual mounting connection, attachment weight and excavator lifting capacity. Powered tools need the specified hydraulic supply.
Which information is needed for a quotation?
Send the excavator model, mounting dimensions, work requirements, quantity and delivery destination.

Excavator Buckets
Heavy-duty bucket
A heavy-duty digging bucket uses thicker plates and additional protection compared with a general-purpose bucket. Its reinforced bottom and protected sides suit harder soil and ground containing smaller stones. For substantial rock content or severe abrasion, compare the rock and heavy-duty rock bucket types.
Excavator Buckets
Rock bucket
A reinforced digging bucket for rock, rubble and abrasive ground. Select the tooth system, bucket profile and wear protection around the material, excavation task and excavator configuration.
Hydraulic Breakers
Box-type hydraulic breaker
A hydraulic breaker with an enclosed housing for rock and concrete breaking. The box-style enclosure protects the breaker body; review local noise requirements and the required machine configuration.
