Product Overview
This attachment pins to the excavator arm in place of the bucket and turns the machine's curl and boom lift into a peeling, ripping action. The tooth bites into the ground, and the operator curls the arm to break the material loose in one smooth motion. Unlike a breaker that pounds the ground with impacts, the ripper uses the excavator's own force to shear and fracture the material — quieter, faster, and more efficient for continuous work along trenches, roadways, and building pads.
The single-tooth design is the industry standard because it puts all the force into one point. Multi-tooth rippers spread the load across several points, which hurts penetration in hard material. A single shank focuses everything into one sharp tooth, giving you maximum bite and adaptability across changing ground conditions. The shank is built from heavy-duty steel — Q345 for mini models, Q345+NM400 wear-resistant steel for 12-ton and up — with a replaceable tooth and adapter. This ripper is part of the TGEC excavator rippers lineup, covering everything from small landscaping jobs to heavy quarry work.

How It Works
This attachment uses the excavator's existing hydraulics — no extra circuits needed. The operator drops the tooth at the start of the rip, lowers the boom to penetrate, then curls the arm to drag the tooth through the material in a peeling action. The tooth breaks the ground as it travels, and the operator repeats the pass along the desired line. The boom lift and arm curl generate the ripping force, which depends on the excavator's hydraulic pressure and arm geometry. The ripper itself has no moving parts — it's a passive tool that relies entirely on the carrier's muscle.
In hard ground, a "stabbing" technique works well — drive the tooth vertically into the material with the boom, then curl the arm to pop it loose. In softer conditions, a continuous peeling motion along the surface is faster. Keep the tooth sharp for best penetration; a dull tooth requires more force and slows you down. The ripper can work in both forward and reverse, and the operator can adjust the attack angle by changing boom and arm positions. When working rock, follow the natural bedding planes — ripping across the grain is tougher and can cause the tooth to bounce.
Application Scenarios
Frozen ground excavation: The ripper cuts through frost layers so you can excavate and grade when the ground is otherwise too hard for a bucket.
Hard clay and hardpan: Dense clay and caliche hardpan yield to the ripper's peeling action, making follow-up digging faster and reducing wear on your bucket and machine.
Weathered rock and shale: Soft to medium rock — shale, sandstone, decomposed granite — can be ripped without drilling and blasting, saving time and money on road and site jobs.
Stump and root removal: The single tooth works around stumps and big roots, breaking them loose for extraction. The shank slips between roots to free the whole root ball.
Trenching and pipeline work: Rippers pre-fracture the ground ahead of the trenching bucket, boosting production and extending bucket life in tough soils.
Road construction: Rippers break up old asphalt and compacted base for recycling, and loosen subgrade for new pavement layers.
Installation & Mounting
Mounting is straightforward — use the existing bucket pins or go through a quick coupler. No hydraulic hookups required; the ripper is a passive attachment that works off the excavator's arm and boom force. Before fitting, confirm that the bracket matches your arm's pin diameter, pin spacing, and width. Custom brackets are available for non-standard dimensions and coupler interfaces. The ripper is lighter than a bucket of comparable size, so it has less impact on lift capacity.
Installation is simple: pull the bucket pins, align the ripper bracket with the arm pin holes, ｉｎｓｅｒｔ the pins, and secure with retaining clips or bolts. If using a quick coupler, follow the coupler manufacturer's attachment procedure. Once mounted, check that all pins are locked in place and that the ripper moves freely through the full arm curl range. Grease the pivots before first use. Confirm that your excavator can safely handle the ripper's weight at your working radius — especially for large models on smaller carriers. No hydraulic connections mean you're ready to rip as soon as it's pinned on.
Wear & Service
The replaceable tooth takes the most abuse — check it daily. A worn tooth kills penetration and transfers extra stress to the shank and adapter. Swap it out when it's past the wear limit or if you see cracking. The adapter needs regular inspection for wear and cracking at the weld joint; have a qualified welder repair or ｒｅｐｌａｃｅ it if damaged. The shank itself is heavy-duty steel built for longevity, but check it for cracks — especially around the mount point and adapter area.
Grease the mounting pins and bushings daily or every 8 hours, and pull them weekly to check for wear. Loose pins create play that stresses the bracket. If you're using a quick coupler, inspect the coupler pins and locking mechanism regularly. The ripper has no hydraulics, so there are no seals, hoses, or cylinders to worry about. Keep a spare tooth and adapter on hand for quick field changes. On large models — 30-ton and up — the tooth may need a sledgehammer or hydraulic press for removal; follow the manufacturer's recommended procedure.
