EW-4000T Rock Rake

⚡ Only 75 HP Required — Lowest in Class

The EW-4000T requires just 75 hp — making it one of the lowest-power-demand rock rakes in the 3.6 m width class worldwide. No need to upgrade your tractor fleet. Compatible with popular compact and mid-range machines including John Deere 5E, New Holland T4, Case IH Farmall A, Kubota M6, Claas Elios, and Fendt 200 V/F series.

🔧 Zero Hydraulic Flow for Rotors

The fully mechanical PTO drive eliminates the need for high hydraulic oil flow to power the rotors. Many compact tractors have only 30–40 L/min hydraulic output — far below the 60+ L/min required by hydraulic-drive stone rakes. The EW-4000T bypasses this limitation entirely, using the PTO for all rotor power.

🛠 Wide 3.6 m Working Width

Cover more ground per pass than most competing stone rakes in the 3–4 meter class. The 3.6-meter working width means fewer passes, less fuel consumption, and significantly higher daily productivity — often achieving 2–4 hectares per hour depending on field conditions.

🔄 Active Lift-and-Separate Technology

Unlike passive drag rakes that merely push rocks across the surface, the EW-4000T’s counter-rotating rotors actively lift stones from the soil, separate fine material, and channel debris into clean windrows. This dramatically reduces the number of passes required and leaves a smoother, seed-ready surface.

💪 Exceptional Reliability & Low Maintenance

Mechanical PTO drive is inherently simpler and more reliable than hydraulic motor systems — no hydraulic hoses, no oil leaks, no motor seals to replace. The cardan shaft, gearbox, and slip clutch are robust, time-proven components that require minimal servicing. This translates to lower annual maintenance costs and more uptime.

💰 Outstanding Cost-Effectiveness

Comparable raking performance to premium European stone rakes at a significantly lower investment — and you don’t need a high-spec tractor to run it. The total cost of ownership (machine + tractor requirement + maintenance) is substantially lower than any hydraulic-drive competitor in this width class.

🌏 Universal Tractor Compatibility

Standard Category 2 three-point hitch and 540 rpm PTO fit virtually every compact and mid-range tractor on the global market. The only hydraulic requirement is 2 double-acting remotes for angle adjustment — a feature standard on almost all modern tractors. No aftermarket hydraulic upgrades, no high-flow pumps, no additional investment.

🌾 Agriculture – Seedbed Stone Clearing on Family Farms

Most European and Asian family farms operate tractors in the 75–120 hp range. The EW-4000T gives these operations access to full 3.6 m professional stone raking without upgrading to a larger tractor. Clear surface stones before seeding grain, potato, or vegetable crops — reducing damage to seeders and harvesters while leaving a smooth, seed-ready surface.

🏗️ Construction – Farm Tracks, Access Roads & Site Cleanup

Small construction and earthmoving contractors often run compact tractors for ancillary tasks. The EW-4000T clears loose stone, rubble, and debris from subgrade surfaces at 3.6 m width — ideal for farm track preparation, access road construction, building pad leveling, and post-demolition cleanup without deploying a large tractor.

⚽ Sports Turf & Landscaping – Surface Refinement

Golf courses, football pitches, cricket grounds, equestrian arenas, and municipal parks need stone-free surfaces for safe play and turf establishment. Turf care contractors often use 80–100 hp compact tractors. The EW-4000T provides a fine-raked finish approaching hand-rake quality at a fraction of the labor cost — with the cab-controlled angle adjustment allowing precision tuning for each soil type.

🌳 Forestry & Land Reclamation

In forestry replanting and land reclamation projects, the EW-4000T removes surface stones, root stumps, and woody debris left after tree felling. The robust spring-steel tines handle thick root material that would jam lighter rakes, preparing a smooth planting bed for seedlings or grass seeding to accelerate revegetation.

🏛️ Municipal & Government Works

Local government maintenance crews typically operate standardized compact tractor fleets. The EW-4000T’s 75 hp requirement means no special procurement — attach it to an existing fleet tractor and start working immediately. Use it for roadside verge clearing, public green space preparation, cemetery ground leveling, and post-flood debris cleanup.

Q1: What is the key difference between the EW-4000T and the EW-4000?

The core difference is the rotor drive system. The EW-4000 uses hydraulic motors (requiring 100 hp and 60 L/min oil flow), while the EW-4000T uses a fully mechanical PTO drive via cardan shaft and gearbox (requiring only 75 hp and zero hydraulic flow for rotor power). Both share the same 3.6 m working width, frame design, tine quality, and raking performance. The EW-4000T is specifically designed for compact tractors with limited hydraulic capacity.

Q2: Can I really run the EW-4000T on a 75 hp tractor?

Yes. The EW-4000T is deliberately engineered for tractors from 75 hp upward. Operators across Europe regularly achieve full 3.6 m coverage at normal field speeds on tractors in the 80–90 hp range. At 1,900 kg, the implement is well within the rear-axle load capacity of most 75+ hp tractors with a Cat 2 three-point hitch.

Q3: What size stones can the EW-4000T handle?

The EW-4000T effectively windrows stones ranging from approximately 50 mm (2 inches) to 500 mm (20 inches) in diameter. Stones smaller than 50 mm generally pass through the tine spacing and remain in the soil — which is typically desirable for maintaining good soil structure and drainage.

Q4: What tractors are compatible with the EW-4000T?

Any tractor with at least 75 hp, a 540 rpm PTO, a Category 2 three-point hitch, and 2 double-acting remotes. Popular compatible models include: John Deere 5E series, New Holland T4, Case IH Farmall A, Kubota M6, Claas Elios, Fendt 200 V/F, Massey Ferguson 4700, and Valtra A series. Because no hydraulic flow is needed for rotor power, even tractors with basic 30–40 L/min hydraulic systems can operate the EW-4000T at full performance.

Q5: How many hectares per hour can the EW-4000T cover?

At 3–5 km/h with a 3.6 m working width, theoretical coverage is 1.1–1.8 hectares per hour. In real-world conditions, most operators achieve 2–4 hectares per hour of effective coverage. Performance is identical to the hydraulic-drive EW-4000 because both models use the same rotor design and working width.

Q6: Are the tines replaceable?

Yes. All tines are individually bolt-on and can be replaced one at a time without special tools or welding. Typical service life is 200–500 operating hours depending on soil abrasiveness and stone density. We supply replacement tine sets at competitive prices with fast international shipping.

Q7: Does the EW-4000T work in wet or clay-heavy soils?

The EW-4000T performs best in moderate moisture conditions. In very wet or heavy clay, soil can stick to the tines. We recommend operating after a few dry days following rain. For consistently heavy clay, reduce working speed to 2–3 km/h and decrease the angle setting to maintain clean windrows. The mechanical PTO drive actually provides more consistent torque than hydraulic motors in heavy conditions, as there is no oil viscosity variation.

Q8: What maintenance does the EW-4000T require?

Routine maintenance includes: greasing all bearing points and the PTO driveline every 8–10 operating hours; checking tine condition and replacing worn tines; inspecting the cardan shaft and universal joints for wear; verifying slip clutch tension and shear bolt condition; and tightening all bolts after the first 5 hours and periodically thereafter. The mechanical drive is inherently simpler than hydraulic systems — no hydraulic hoses, filters, or motor seals to service.

Q9: Do you ship the EW-4000T internationally?

Yes, we export worldwide. Production takes 15–20 days, with shipping transit depending on the destination port. We handle export documentation and can provide CIF or FOB pricing. Full-container and LCL shipping options are available to any major port. Please contact our sales team for a detailed quotation.

Q10: Can the EW-4000T work together with a stone crusher?

Absolutely. The EW-4000T is designed to complement agricultural stone crushers. The recommended workflow is: first pass with the EW-4000T to windrow all surface stones into neat rows, then process the windrows with a stone crusher or collect them with a stone picker. This two-stage approach concentrates stone material into defined rows, dramatically improving crusher efficiency compared to processing an entire field surface.
