Product Introduction
This road trenching machine is a heavy tractor-mounted disc digging attachment built for hard pavement, compacted soil and rocky ground, widely used in municipal road engineering and agricultural planting projects. Also named a professional road trencher, it adopts a large serrated alloy cutting disc to cut straight vertical narrow trenches on cement, asphalt and hard clay. It works as a reliable orchard ditching machine to dig deep drainage and fertilization furrows for fruit groves, and also serves as multi-purpose farmland ditching equipment for irrigation channels and farm pipeline burial. Matched with wheel tractors above 100 horsepower, it uses rear three-point suspension and a heavy-duty Steyr rear axle gearbox for stable high-load operation, with fully customizable trench depth and width to meet different construction and agricultural standards.

Material & Structural Construction
Frame & Disc Material: Main frame and cutting disc are made of thickened high-strength manganese steel plate via laser cutting, resistant to bending and impact under heavy digging loads.
Digging Teeth: Each cutting tooth is hot-forged wear-resistant alloy steel, with strong penetration ability on concrete and hard soil, individually replaceable to lower maintenance cost.
Transmission Gearbox: Heavy-duty cast steel Steyr rear axle gearbox, fully sealed dustproof and waterproof to block mud and gravel intrusion during long-hour field work.
Soil Separation Shield: Integrated stamped steel soil deflector evenly pushes excavated soil to both sides of the trench to avoid backfilling.
Suspension Bracket: Thickened welded triangular support frame, high structural rigidity without shaking during high-speed disc rotation.

3.Fast global spare parts supply chain: alloy digging teeth, gearbox seals and suspension fittings can be delivered within 7 working days after order confirmation.
4.Custom modification service: adjust disc diameter, trench depth and width according to local municipal and agricultural construction standards, offering free customized drawings for bulk full-container orders.
Practical Common Fault Solutions
1.Road trenching machine disc gets stuck and stops rotating during pavement cutting Solution: Shut down power first, clear concrete and gravel jammed between alloy teeth; check gearbox oil level and replenish dedicated heavy-load lubricant; adjust chain tension to eliminate transmission jamming.
2.Trench depth becomes uneven during continuous operation Solution: Inspect tractor hydraulic lifting cylinder for oil leakage, remove dirt blocking cylinder stroke and recalibrate the depth limit support bracket.
3.Gearbox generates loud abnormal knocking noise Solution: Drain aged contaminated gear oil and refill high-viscosity anti-wear lubricant; disassemble to check for worn gears or damaged bearings and replace damaged parts timely.
4.Digging teeth wear rapidly when working on rocky hard ground Solution: Reduce tractor forward travel speed to avoid overloading the cutting disc; prepare spare alloy teeth for batch replacement and keep the disc vertical to the ground while trenching.
