Manufactured by Ever-Power in Brazil, it utilizes a heavy-duty milling rotor equipped with 92 Kennametal RK4 bits to cut, pulverize, and mix soil up to a depth of 200 mm. Operating in tandem with a water truck via a direct distribution hose, it applies controlled dosing directly to the soil, ensuring optimal moisture content for compaction. This machine is engineered to improve traffic flow for heavily loaded trucks, significantly reducing fleet maintenance requirements and cutting operational costs between the field and factory.<\/p>\n<ul data-path-to-node=\"10\">\n<li>\n<p data-path-to-node=\"10,0,0\"><b data-path-to-node=\"10,0,0\" data-index-in-node=\"0\">Adjustable Milling Depth:<\/b> The machine features a simple and fast adjustment concept, allowing operators to set the milling depth precisely between 0 and 200 mm based on road conditions.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,1,0\"><b data-path-to-node=\"10,1,0\" data-index-in-node=\"0\">Heavy-Duty Rotor System:<\/b> Equipped with a robust RK4 rotor utilizing 92 Kennametal bits and fixation blocks, designed for maximum wear resistance in various abrasive soil types.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,2,0\"><b data-path-to-node=\"10,2,0\" data-index-in-node=\"0\">Tractor Requirements:<\/b> Requires a minimum tractor power rating of 250 CV (HP) with a 1000 RPM PTO rotational speed and a 1.3\/8 inch 21-spline input for optimal kinetic energy transfer.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,3,0\"><b data-path-to-node=\"10,3,0\" data-index-in-node=\"0\">Integrated Fluid Application:<\/b> Features a built-in liquid reservoir and application nozzles that connect to a water truck, allowing simultaneous soil milling and moisture conditioning in a single pass.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,4,0\"><b data-path-to-node=\"10,4,0\" data-index-in-node=\"0\">High Operational Efficiency:<\/b> Operates at a steady speed of 0.5 to 1.5 Km\/h (using a CVT transmission), delivering a massive 5300 Kg of approximate operating weight to prevent bouncing and ensure uniform soil stabilization.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"12\"><strong>Product Overview &amp; Value Proposition<\/strong><\/h2>\n<p data-path-to-node=\"13\"><b data-path-to-node=\"13\" data-index-in-node=\"0\">Engineered for Rural Road Improvement<\/b><\/p>\n<p data-path-to-node=\"13\">The continuous traffic of heavily loaded agricultural and mining trucks causes severe degradation of unpaved rural roads, leading to deep ruts, dust pollution, and increased vehicle maintenance. The THOR ST Soil Stabilizer provides a permanent structural solution. By milling the existing degraded road surface and mixing it with water or chemical binders, it creates a homogeneous, high-load-bearing base layer.<\/p>\n<p data-path-to-node=\"14\"><b data-path-to-node=\"14\" data-index-in-node=\"0\">Dust Reduction and Operational Safety<\/b><\/p>\n<p data-path-to-node=\"14\">Fugitive dust from rural roads decreases visibility and poses significant safety hazards. The THOR ST incorporates application nozzles connected directly to a water truck. This controlled dosing applied directly to the soil during the milling process locks in fine particles, significantly reducing dust emissions and enhancing overall operational safety for rural communities and transport fleets.<\/p>\n<p data-path-to-node=\"15\"><b data-path-to-node=\"15\" data-index-in-node=\"0\">Reduced Fleet Maintenance and CO2 Emissions<\/b><\/p>\n<p data-path-to-node=\"15\">Rough, unstable roads cause extreme wear and tear on truck suspensions, tires, and drivetrains. By rehabilitating the road surface with the THOR ST, transport companies experience a massive reduction in fleet maintenance requirements. Furthermore, optimized road surfaces reduce rolling resistance, leading to shorter transportation times, lower fuel consumption, and subsequently, lower CO2 emissions per ton of cargo transported.<\/p>\n<h2 data-path-to-node=\"17\"><strong>Technical Specifications Table<\/strong><\/h2>\n<p><img decoding=\"async\" class=\"alignnone wp-image-364 size-full\" src=\"https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions.webp\" alt=\"THOR ST Soil Stabilizer Main Dimensions\" width=\"1553\" height=\"604\" srcset=\"https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions.webp 1553w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-300x117.webp 300w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-1024x398.webp 1024w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-768x299.webp 768w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-1536x597.webp 1536w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-18x7.webp 18w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-1080x420.webp 1080w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-1280x498.webp 1280w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-980x381.webp 980w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-480x187.webp 480w, https:\/\/soil-stabilisor.com\/wp-content\/uploads\/2026\/03\/THOR-ST-Soil-Stabilizer-Main-Dimensions-600x233.webp 600w\" sizes=\"(max-width: 1553px) 100vw, 1553px\" \/><\/p>\n<p data-path-to-node=\"18\">The following table details the engineering parameters of the THOR ST Soil Stabilizer, adhering to strict international manufacturing standards.<\/p>\n<table border=\"1\" data-path-to-node=\"19\">\n<thead>\n<tr>\n<td><strong>Item<\/strong><\/td>\n<td><strong>Parameter<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"19,1,0,0\"><b data-path-to-node=\"19,1,0,0\" data-index-in-node=\"0\">Model<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,1,1,0\">THOR ST Soil Stabilizer<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,2,0,0\"><b data-path-to-node=\"19,2,0,0\" data-index-in-node=\"0\">Transport Length<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,2,1,0\">2960 mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,3,0,0\"><b data-path-to-node=\"19,3,0,0\" data-index-in-node=\"0\">Transport Width<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,3,1,0\">2745 mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,4,0,0\"><b data-path-to-node=\"19,4,0,0\" data-index-in-node=\"0\">Transport Height<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,4,1,0\">2615 mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,5,0,0\"><b data-path-to-node=\"19,5,0,0\" data-index-in-node=\"0\">Approximate Operating Weight<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,5,1,0\">5300 Kg<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,6,0,0\"><b data-path-to-node=\"19,6,0,0\" data-index-in-node=\"0\">Adjustable Milling Depth<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,6,1,0\">0 to 200 mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,7,0,0\"><b data-path-to-node=\"19,7,0,0\" data-index-in-node=\"0\">Minimum Power Rating<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,7,1,0\">250 CV (HP)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,8,0,0\"><b data-path-to-node=\"19,8,0,0\" data-index-in-node=\"0\">Operating Speed<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,8,1,0\">0.5 to 1.5 Km\/h (CVT Transmission Required)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"19,9,0,0\"><b data-path-to-node=\"19,9,0,0\" data-index-in-node=\"0\">PTO Input Specification<\/b><\/span><\/td>\n<td><span data-path-to-node=\"19,9,1,0\">1.3\/8 inch &#8211;

John M., County Road Commissioner, Midwest USA:<\/b><\/p>\n<p data-path-to-node=\"57\">&#8220;We manage over 400 miles of unpaved gravel roads that get destroyed every harvest season by grain carts. We used to spend a fortune on bringing in new crushed stone. Since we acquired the THOR ST as a replacement for our older, high-maintenance European stabilizer, we&#8217;ve completely changed our strategy. We now mill the existing material, inject stabilizing enzymes right from the water truck, and compact it. The RK4 bits easily handle the embedded rocks, and the road holds up through the winter frost. It\u2019s saved the county budget immensely.&#8221;<\/p>\n<p data-path-to-node=\"58\"><b data-path-to-node=\"58\" data-index-in-node=\"0\">2. Carlos S., Logistics Manager, Sugarcane Mill, S\u00e3o Paulo, Brazil:<\/b><\/p>\n<p data-path-to-node=\"58\">&#8220;In the rainy season, our bi-train trucks would sink up to their axles in the mud, causing massive delays to the mill. We needed a heavy-duty solution. The THOR ST from Ever-Power is a beast. We tow it with a Case IH Magnum 310. It grinds the lateritic clay, we mix in a little lime, and the result is a road as hard as concrete. The fact that the machine is manufactured locally means if we need a replacement bit or a service part, we get it the next day, not next month. Excellent factory support.&#8221;<\/p>\n<p data-path-to-node=\"59\"><b data-path-to-node=\"59\" data-index-in-node=\"0\">3. David L., Mining Contractor, Western Australia:<\/b><\/p>\n<p data-path-to-node=\"59\">&#8220;Dust control and corrugation on our haul roads were causing our articulated dump trucks to require constant suspension rebuilds. We brought in the THOR ST to rehabilitate the main arteries. The integrated liquid reservoir and application nozzles are exactly what we needed. We hook it up to our water bowser, mill down 150mm, and get the moisture content perfect in one pass. It completely pulverized the washboards. The Kennametal bits show surprisingly little wear even in this highly abrasive iron-rich soil.&#8221;<\/p>\n<p data-path-to-node=\"60\"><b data-path-to-node=\"60\" data-index-in-node=\"0\">4. Alexey V., Forestry Infrastructure Director, Siberia, Russia:<\/b><\/p>\n<p data-path-to-node=\"60\">&#8220;The Rasputitsa mud makes logging operations nearly impossible in the spring. We needed a machine that could operate in brutal conditions to stabilize our main extraction routes. The THOR ST&#8217;s robust gearbox and 5300 kg weight keep it stable even when breaking through frozen ruts. We use it to mix cement deep into the subgrade. It has transformed our logistics, allowing us to extend our hauling season by several weeks. A very reliable, heavily built machine that doesn&#8217;t rely on overly complex electronics that fail in the cold.&#8221;<\/p>\n<p data-path-to-node=\"61\"><b data-path-to-node=\"61\" data-index-in-node=\"0\">5. Pieter vd M., Agricultural Contractor, Free State, South Africa:<\/b><\/p>\n<p data-path-to-node=\"61\">&#8220;Many local farmers cannot afford to pave their access roads, but the dust and potholes ruin their transport vehicles. I started a contracting business offering soil stabilization. The THOR ST was the perfect investment. It is highly affordable compared to self-propelled units, yet it does the exact same job. I pull it with a John Deere 8R. Adjusting the milling depth is incredibly fast using the hydraulic cover adjustment. The quality of the road base we leave behind always results in repeat business from neighboring farms.&#8221;<\/p>\n<h2 data-path-to-node=\"63\"><strong>Synergistic Equipment: The DCW 2.2 Binder Spreader<\/strong><\/h2>\n<p data-path-to-node=\"64\">For the ultimate soil stabilization process, the THOR ST works perfectly in conjunction with our <b data-path-to-node=\"64\" data-index-in-node=\"97\">DCW 2.2 Binder Spreader<\/b>.<\/p>\n<p data-path-to-node=\"65\">While the THOR ST mixes the soil, the DCW 2.2 is designed for the precise, dust-free distribution of powder binders (lime or cement) ahead of the stabilizer. Mounted at the front of the tractor, it features two internal rollers allowing application in 2-meter or 1-meter widths. It includes an integrated electronic control system operated from a display in the tractor cab, ensuring uniform application rates with minimal waste, completely outperforming manual &#8220;bag-spread&#8221; methods. By utilizing the DCW 2.2 on the front linkage and the THOR ST on the rear PTO, contractors can achieve continuous, high-precision soil stabilization in a single pass.<\/p>\n<h2 data-path-to-node=\"67\"><strong>Installation &amp; Operation Guide<\/strong><\/h2>\n<p data-path-to-node=\"68\"><b data-path-to-node=\"68\" data-index-in-node=\"0\">Step 1: Tractor Coupling<\/b><\/p>\n<p data-path-to-node=\"68\">Reverse the tractor and attach the THOR ST to the heavy-duty Category 3 or 4 three-point hitch. Ensure the locking pins are fully engaged and secured.<\/p>\n<p data-path-to-node=\"69\"><b data-path-to-node=\"69\" data-index-in-node=\"0\">Step 2: PTO Connection<\/b><\/p>\n<p data-path-to-node=\"69\">Connect the PTO shaft to the tractor&#8217;s 1.3\/8&#8243; 21-spline output. Ensure the PTO shaft is properly sized (not bottoming out or over-extended during lifting). Attach the safety chains.<\/p>\n<p data-path-to-node=\"70\"><b data-path-to-node=\"70\" data-index-in-node=\"0\">Step 3: Hydraulic &amp; Fluid Connection<\/b><\/p>\n<p data-path-to-node=\"70\">Connect the hydraulic hoses to the tractor&#8217;s SCV (Selective Control Valve) to operate the cover adjustment cylinder. If using the liquid reservoir, connect the supply hose from the accompanying water truck to the THOR ST&#8217;s input manifold.<\/p>\n<p data-path-to-node=\"71\"><b data-path-to-node=\"71\" data-index-in-node=\"0\">Step 4: Depth Adjustment<\/b><\/p>\n<p data-path-to-node=\"71\">Use the tractor&#8217;s hydraulic controls to adjust the rear cover cylinder. Use the integrated depth gauge (0-200 mm) on the side of the machine to set the desired milling depth based on the road rehabilitation requirements.<\/p>\n<p data-path-to-node=\"72\"><b data-path-to-node=\"72\" data-index-in-node=\"0\">Step 5: Operation<\/b><\/p>\n<p data-path-to-node=\"72\">Engage the PTO slowly until it reaches the operational speed of 1000 RPM. Lower the machine into the soil while moving forward at a steady CVT speed of 0.5 to 1.5 Km\/h. Engage the water pump on the water truck to begin fluid injection through the application nozzles.<\/p>\n<h2 data-path-to-node=\"74\"><strong>Frequently Asked Questions (FAQ)<\/strong><\/h2>\n<p data-path-to-node=\"75\"><b data-path-to-node=\"75\" data-index-in-node=\"0\">Q1: What is the primary difference between a soil stabilizer and a stone crusher?<\/b><\/p>\n<p data-path-to-node=\"75\">A: A soil stabilizer like the THOR ST is designed to mill the existing ground, pulverize soil clods, and mix in binders or water in-situ to create a load-bearing road base. A stone crusher is a stationary or tracked machine designed to reduce the size of solid rock boulders into aggregate.<\/p>\n<p data-path-to-node=\"76\"><b data-path-to-node=\"76\" data-index-in-node=\"0\">Q2: Can the THOR ST crush solid bedrock?<\/b><\/p>\n<p data-path-to-node=\"76\">A: No. While the Kennametal RK4 bits can easily handle loose rocks, gravel, and highly compacted hardpan, the machine is not designed to mill solid, continuous bedrock.<\/p>\n<p data-path-to-node=\"77\"><b data-path-to-node=\"77\" data-index-in-node=\"0\">Q3: How deep can the THOR ST mill?<\/b><\/p>\n<p data-path-to-node=\"77\">A: The milling depth is infinitely adjustable between 0 mm and 200 mm, allowing for surface scarification or deep base layer stabilization.<\/p>\n<p data-path-to-node=\"78\"><b data-path-to-node=\"78\" data-index-in-node=\"0\">Q4: Why does it require a CVT transmission tractor?<\/b><\/p>\n<p data-path-to-node=\"78\">A: The PTO must run at a constant 1000 RPM to provide the rotor with enough kinetic energy to mill hard soil. A CVT (Continuously Variable Transmission) allows the tractor to move forward very slowly (0.5 Km\/h) independent of the engine RPM, preventing the tractor from stalling.<\/p>\n<p data-path-to-node=\"79\"><b data-path-to-node=\"79\" data-index-in-node=\"0\">Q5: What happens if a Kennametal RK4 bit wears out or breaks?<\/b><\/p>\n<p data-path-to-node=\"79\">A: The bits are designed for quick replacement. Using a standard extraction tool, the worn bit can be knocked out of the fixation block, and a new bit tapped in, minimizing downtime.<\/p>\n<p data-path-to-node=\"80\"><b data-path-to-node=\"80\" data-index-in-node=\"0\">Q6: Does the machine come with the water truck?<\/b><\/p>\n<p data-path-to-node=\"80\">A: No, the THOR ST is the stabilization implement. It features the liquid reservoir, manifolds, and nozzles, but it must be tethered to a separate water or chemical truck that drives alongside or ahead of the tractor.<\/p>\n<p data-path-to-node=\"81\"><b data-path-to-node=\"81\" data-index-in-node=\"0\">Q7: How is the fluid application controlled?<\/b><\/p>\n<p data-path-to-node=\"81\">A: The fluid flows from the water truck into the THOR ST&#8217;s reservoir and is distributed through heavy-duty application nozzles directed straight into the milling chamber for instant, dust-free mixing.<\/p>\n<p data-path-to-node=\"82\"><b data-path-to-node=\"82\" data-index-in-node=\"0\">Q8: Can I use cement or lime with this machine?<\/b><\/p>\n<p data-path-to-node=\"82\">A: Yes. For optimal results, use our DCW 2.2 Binder Spreader mounted on the front of the tractor to lay the cement\/lime powder, which the THOR ST then mixes deeply into the soil.<\/p>\n<p data-path-to-node=\"83\"><b data-path-to-node=\"83\" data-index-in-node=\"0\">Q9: What maintenance is required for the gearbox?<\/b><\/p>\n<p data-path-to-node=\"83\">A: The gearbox requires periodic checking of the synthetic gear oil level and complete oil changes every 500 operating hours or annually, depending on usage severity.<\/p>\n<p data-path-to-node=\"84\"><b data-path-to-node=\"84\" data-index-in-node=\"0\">Q10: Are spare parts readily available?<\/b><\/p>\n<p data-path-to-node=\"84\">A: Yes, Ever-Power maintains a comprehensive inventory of Kennametal RK4 bits, fixation blocks, belts, and gearbox components at our Brazilian factory, ready for rapid global dispatch.<\/p>\n<h2 data-path-to-node=\"86\"><strong>Anti-Hallucination Notes<\/strong><\/h2>\n<ul data-path-to-node=\"87\">\n<li>\n<p data-path-to-node=\"87,0,0\"><i data-path-to-node=\"87,0,0\" data-index-in-node=\"0\">Please note that the required operating speed (0.5 &#8211; 1.5 Km\/h) will vary strictly based on the soil density, moisture content, and milling depth.
