Excavator Ripper Rake

The Monde Ripper Rake excavator rake is the land sorting and clearing attachment that separates roots, stones, plant debris, and waste from the soil without retaining the earth. The curved tines penetrate the soil efficiently and let the fine particles pass through, collecting only the coarse material that needs to be removed.

The excavator rake is compatible with machines from 0.5 to 70 tonnes, with 9 serialized models for excavators from 3 to 45 tonnes, fabricated from high-strength Q460 steel or the Q460 + NM400 combination for the higher tonnage classes.

The Monde excavator rake replaces laborious manual land-clearing work — clearing land covered with vegetation, preparing frozen or compact soil, removing construction debris, and sorting granular materials are operations the excavator rake performs quickly, with the operator safely in the machine cab, without additional personnel on the ground. Key advantages of the Monde Ripper excavator rake

• Sorting without retaining the soil — the curved tines of the excavator rake are designed to retain coarse materials (roots, stones, debris) and let the fine soil and small particles pass freely between the tines. The ground stays in place, the unwanted material is collected and deposited separately — without losing fertile soil or creating excess volumes of mixed material that must be transported.

• 9 models — full coverage 3–45 tonnes — the Monde excavator rake is available in 9 configurations for excavators from 3 tonnes (mini-excavators for work in confined spaces) up to 45 tonnes (heavy excavators for high-volume earthworks and intensive forestry work). Each model is structurally sized for the forces specific to its tonnage class.

• Q460 and NM400 steel — for excavators of 3–16 tonnes, the excavator rake uses Q460 steel (yield strength 460 MPa). From 17 tonnes up, the structure combines Q460 with NM400 — a wear-resistant steel with high Brinell hardness, specific to applications with abrasive soils, gravel, and rocky material. This material choice ensures superior tine durability compared to standard structural steels.

• Curved tines for penetration into hard and frozen soils — the curved profile of the excavator rake's tines allows penetration into compact, clayey, or frozen soils without excessive impact force. The curve of the tine distributes the load progressively along the entire contact length with the soil, reducing wear and the risk of breakage compared to straight tines.

• Steel thickness 50–110 mm depending on the model — the Monde excavator rake is fabricated with plate thicknesses between 50 mm (the 3–5 tonne model, 260 kg) and 110 mm (the 36–45 tonne models, 870–920 kg). The greater tine thickness on the higher classes corresponds to the higher hydraulic forces and elevated mechanical stresses of heavy excavators.

• Quick-coupler compatible — the Monde excavator rake mounts on the standard excavator mount, compatible with the Monde DEHN quick coupler if the machine is equipped with one. Switching between the digging bucket and the excavator rake is done from the cab in less than a minute.

• Operator safely in the cab — the excavator rake eliminates the need for personnel on the ground to manually clear land with dense vegetation, roots, or construction debris — operations with a high risk of injury from projected objects or falls on rough terrain.

• 60-month UZINEX warranty — extended coverage with spare parts in stock in Iași and national technical support 24–48 hours.

The excavator rake is the standard attachment for all work in which the ground must be cleared of coarse material without moving the total volume of soil — the typical situation in forestry, extensive agriculture, construction work on vegetated land, and the rehabilitation of degraded land.

Clearing land before construction is the most frequent application. On land with shrub vegetation, shallow roots, stones, and organic debris, the excavator rake clears the surface quickly and systematically, separating the coarse material from the soil. The resulting ground can be compacted directly or leveled for foundations, without transporting large volumes of mixed soil to a dump.

Forestry work — clearing felling areas after timber harvesting, removing stumps and roots after cutting, preparing the ground for replanting — are classic applications of the excavator rake. The 17–45 tonne models with the Q460 + NM400 combination are sized for resistance to impact with large roots and significantly sized stones typical of forest terrain.

Preparation of compacted or frozen agricultural soil before plowing or installing irrigation systems uses the excavator rake to break up the surface layer and remove gravel from alluvial or mountain soils. The curved tines of the excavator rake fragment the frozen crust without excessively disaggregating the structure of the fertile soil.

Rehabilitation of industrial land and former waste dumps uses the excavator rake to separate construction debris (pieces of concrete, brick, scrap metal) from the fill soil, allowing recovery of the clean soil and selective disposal of the waste. Why Q460 + NM400 matters for the excavator rake

The excavator rake works in abrasive conditions — the tines are in permanent contact with gravel, stone, compact soil, and high-hardness materials. The abrasive wear of the tines is the determining factor in the service life of the excavator rake, not resistance to static loads.

Q460 steel (the base structure) provides mechanical strength — a yield strength of 460 MPa and high toughness prevent permanent deformation of the tines under the excavator's hydraulic forces. NM400 steel (wear-resistant steel, Brinell hardness 370–430 HB) provides abrasion resistance on the surfaces in contact with hard materials.

Combining the two materials in the excavator rake from 17 tonnes up reflects the fact that heavier excavators generate greater hydraulic forces — the tines are stressed simultaneously in bending (requiring Q460) and surface wear (requiring NM400). A single material does not optimize both properties at once. Frequently asked questions about the excavator rake

Can the excavator rake be used as a ripper (scarifier) for compact soil?

Yes — the curved tines of the excavator rake are also designed for penetrating and fragmenting compact, clayey, or frozen soils, not just for sorting. The difference compared to a dedicated single-tine ripper is that the excavator rake produces a wider working zone and fragments a larger surface at once, but with less force concentrated per point than the single-tine ripper. For extremely compact or rocky soil, the dedicated ripper is more efficient. What is the spacing between the tines, and what maximum stone size can the excavator rake retain?

The spacing between the tines of the excavator rake and the maximum size of the retained material varies depending on the chosen model. UZINEX engineers provide the exact tine-opening dimensions for the specific model at quotation, depending on the type of material and the grain size required for your application. Can the excavator rake be mounted on the quick coupler?

Yes — the Monde excavator rake is compatible with the standard excavator mount, including the Monde DEHN hydraulic quick coupler if the machine is equipped with one. Switching between the excavator rake and the digging bucket or other attachments is done from the cab in less than a minute on excavators with a quick coupler. Is the excavator rake eligible for SEAP/SICAP public procurement?

Yes. UZINEX is a member of the Enterprise Europe Network and delivers equipment for projects with EU funds and public procurement via SEAP/SICAP. Complete technical documentation is provided on request. Leasing options available on the UZINEX credit and leasing page. Why UZINEX for your excavator rake
