Fortunately, the RC208-21904 Carrier Roller Assembly—purpose-built for Kubota mini excavators—is now in stock. As a premium aftermarket replacement, it streamlines maintenance and resolves all your repair pain points in one go.
✅ Precision Compatibility: Match These Kubota Models Perfectly – No Guesswork
Not all carrier rollers are engineered to match Kubota’s compact excavator specifications. This RC208-21904 assembly is a dedicated solution, ideal for mechanics and operators servicing the following key models:
Courtyard Renovation & Nursery Operations: KX71-2 (specialized for soil tilling and underground pipe installation), KX101 (lightweight grading, designed to avoid lawn damage)
Orchard & Greenhouse Applications: KX121-2/KX121-2S (optimized for digging drip irrigation trenches, efficiently covering 20 mu of land daily)
Municipal Minor Repairs & Site Clearance: KX91-2/KX91-2SS (suitable for sidewalk repairs and construction waste removal, with excellent maneuverability in narrow spaces)
Short-Distance Small-Scale Projects: K030 (brick handling and foundation pit cleaning), K035 (integrated digging-hauling, paired with loaders for material transfer)
Even if you cannot recall your excavator’s exact model, simply share your operational scenario (e.g., “I use my Kubota for orchard ditch digging”)—our team will instantly confirm compatibility.
✅ 15-Minute Installation: No Professional Mechanic Required, Save ¥80 on On-Site Service Costs
Maintenance delays often stem from missing parts or complex installation. This assembly is engineered to eliminate both issues:▪️ Ready-to-Install Out of the Box: Includes Kubota OEM-matching nuts and anti-slip washers. No trips to hardware stores to verify fastener sizes (e.g., M8 vs. M10), and the anti-slip washers prevent vibration-induced loosening—three times more durable than standard aftermarket washers.▪️ Beginner-Friendly Design: As a compact carrier roller, it mounts directly to the central top of the undercarriage. No track removal or equipment repositioning is needed; simply align with the bolt holes and tighten. Field tests confirm: the entire process (removing the old roller + installing the new one) takes just 15 minutes—cutting 2 hours off the wait time for on-site mechanic support.▪️ Missing Parts Support: If a washer is misplaced during unboxing, contact our customer service for immediate 补发 (replacement shipment)—no impact on same-day maintenance schedules.
✅ Superior Durability: Minimal Wear After 300 Hours on Gravel – 2 Months Longer Than Standard Rollers
Kubota mini excavators frequently operate on harsh surfaces (gravel, shallow mud, or humus-rich greenhouse soil)—so durability is non-negotiable. This assembly incorporates targeted enhancements for tough conditions:
High-Strength Wear-Resistant Shell: Constructed from premium cast iron. In field testing: operating 5 hours daily on gravel surfaces, the roller showed only minor scratches after 300 hours—outperforming standard carrier rollers (which develop deep grooves after just 150 hours) by a 2-month lifespan extension.
Sealed Bearing Protection: Equipped with double-lip dust seals that block mud, water, and grass clippings from entering the internal bearing. Even in humus-heavy greenhouse environments or rainy-season ditch digging, users report zero jamming or abnormal noise.
