Rotary tiller blades are the core consumable part of any rotary tiller and rotavator. For fields full of stones, gravel and compacted hard soil, ordinary tiller blades wear out quickly or break frequently, raising your downtime and replacement cost. Our hardfaced rotavator blade is engineered specifically for these tough working conditions. We apply alloy hard surfacing welding on the cutting edge, the highest wear area of the blade. The base body is forged high manganese steel with complete heat treatment, so the blade stays tough to absorb impact while the alloy tip resists abrasion. This combination delivers far longer working life than regular plain tiller knives. It helps you finish seedbed preparation, stubble mixing and soil crumbling with fewer blade changes, cutting your overall farming operating cost.
Standard tiller blades wear fast on the cutting edge when rubbing against sand and stone. Hardfacing adds a hard alloy overlay only on the working tip, without making the whole blade brittle.
The alloy tip: high hardness, anti-abrasion, slow wearing
Manganese steel body: good toughness, shock resistant, anti-break when striking rocks
Optimized curved profile: reduces tillage resistance, improves soil pulverization and saves tractor fuel consumption
✅ Extended Service Life for Stony LandHard surfacing alloy overlay greatly improves wear resistance. It lasts 2–3 times longer than normal rotary tiller blades in gravel and rocky farmland.
✅ High Manganese Steel Body, Impact ResistantForged and heat-treated high manganese steel absorbs sudden shock, prevents blade breakage and bending during heavy tillage.
✅ Precision Machined for Easy InstallationStandard mounting hole position, consistent hole size, direct swap for original rotavator blades, no modification required.
✅ Excellent Soil Cutting & Crumbling PerformanceScientific curved blade design cuts into soil smoothly, breaks clods, mixes straw and residue evenly into topsoil for high-quality seedbed.
✅ Wide CompatibilityFits most tractor-mounted rotary tillers, rotavators and cultivators for dry farmland, orchards, hilly land and wasteland reclamation.
✅ Bulk & OEM SupportWe support custom sizes, custom marking, OEM packaging for distributors and agricultural parts wholesalers.

Check your original blade length, hole diameter and hole spacing first
Match soil condition: Choose hardfaced version if you have stony, gravelly soil; standard blades work fine for soft alluvial soil
Confirm rotation direction: Left-hand / Right-hand blades for your rotavator rotor
Confirm quantity: Rotavator shafts require matched sets of L & R blades
Disconnect tractor power before replacing blades
Check blade mounting bolts and replace worn bolts at the same time
Keep the cutting edge sharp; avoid hitting large rocks wherever possible
Inspect hardfaced tip regularly; replace the blade once the alloy overlay is fully worn away
