Product Introduction
This road grooving machine is a heavy tractor-mounted trenching attachment designed for hard pavement, concrete, compacted soil and gravel ground. Also known as a reliable road slotting machine, it adopts a large serrated cutting disc structure to cut neat vertical narrow trenches on asphalt, cement and hard clay surfaces. As a high-efficiency ditching machine for engineering and agricultural dual use, it relies on a heavy-duty gearbox to drive the disc cutter for continuous deep cutting. Classified as a robust disc excavator, it can dig customizable depth and width slots without side wall collapse, and it acts as a professional ground groover for municipal pipeline laying, roadside curb grooving and orchard drainage trenching. It requires tractors above 100 horsepower for matching, with rear three-point suspension and stable gear transmission to support long-hour high-load construction work.
Core Competitive Advantages
Powerful Hard Surface Cutting Performance: Thickened alloy hard teeth on the cutting disc easily break concrete, cement and compacted hard soil, far more suitable for rigid pavement than small chain trenchers.
Clean Vertical Trench Molding: The circular disc cuts smooth straight trench walls, reducing extra trimming labor and guarantee standard pipeline burial conditions.
Adjustable Custom Sizes: Trench depth from 20cm to 100cm and width from 10cm to 35cm can be customized to match different construction and agricultural project standards.
High Stable Working Efficiency: Continuous linear working speed reaches 60–90 meters per hour, greatly improving construction progress for large municipal road renovation projects.
Durable Heavy-Duty Transmission System: Equipped with Steyr heavy-duty rear axle gearbox, thick cast steel shell resists impact and abrasion, lowering long-term failure rates.
Standardized Production Process
Every road grooving machine undergoes strict multi-step precision production before delivery:
1.Laser Cutting: High-precision blanking for frame brackets, disc panels and gearbox housings to eliminate dimensional errors.
2.CNC Bending & Forging: Heavy-duty bending equipment shapes load-bearing frames; cutting teeth are forged with wear-resistant alloy for long service life.
3.Shot Blasting Rust Removal: Full surface shot blasting removes rust and oxide layers to enhance paint adhesion and anti-corrosion performance.
4.Full Penetration Welding: Professional welders complete seamless welding on all stress joints, avoiding frame fracture under heavy digging loads.
5.Assembly & Load Testing: After full assembly, each unit undergoes 2-hour continuous load running test to inspect gearbox, disc rotation and suspension stability.
Complete After-Sales Support for Global Buyers
1.12-month factory warranty for core gearbox and drive disc assembly under standard operating conditions.
2.Professional multilingual technical team provides 24/7 online video installation, operation and troubleshooting guidance.
3.Fast global spare parts supply chain: alloy cutting teeth, gearbox seals and suspension accessories can be delivered within 7 working days.
4.Custom modification service: adjust disc diameter, suspension length and trench specifications according to local road engineering standards, providing free customized design drawings for bulk orders.
Real Global Customer Reviews
Municipal engineering contractors highly recognize this road grooving machine for its stable performance on cement and asphalt roads. Many buyers comment that this road slotting machine cuts construction labor costs significantly due to its high hourly output. Farm and orchard dealers praise this ditching machine for its deep digging capacity for irrigation and fertilization furrows. Overseas distributors note the disc excavator's thick wear-resistant teeth extend service life, while maintenance costs stay low. Road maintenance teams also feedback that this ground groover produces tidy trenches that meet pipeline construction acceptance standards, winning consistent repeat orders from engineering clients.
