Agricultural Lubricant Solutions
Field-Proven Fluids for Maximum Uptime During Critical Harvest Windows
HSO Lubricant engineers precision agricultural fluids that protect high-value machinery from sub-zero winter starts to peak summer heat. Our formulations meet or exceed OEM specifications for John Deere, Case IH, New Holland, Kubota, and AGCO equipment.
Agricultural Excellence & Heavy-Duty Engineering
Engineered to maximize productivity under the most grueling field conditions, our specialized agricultural and heavy machinery line delivers comprehensive, multi-system protection. From high-performance STOU and UTTO tractor fluids optimized for smooth transmission and wet-brake operations, and heavy-duty diesel engine oils built for extended-drain reliability in high-dust environments, to eco-certified biodegradable hydraulic fluids designed for safe operation near sensitive watersheds, we secure your operational uptime while protecting the surrounding ecosystem.
Tractor Fluids — STOU & UTTO
Superior hydraulic, transmission, and wet-brake performance for modern high-horsepower tractors.
- STOU (Super Tractor Oil Universal): Meets API GL-4, John Deere J20C, Case IH MS-1209, New Holland FNHA-2-C.201.00.
- UTTO (Universal Tractor Transmission Oil): Optimized for powershift and CVT transmissions. Friction stability for wet-disc brakes and PTO clutches.
- Viscosity Grades: SAE 10W-30, 10W-40, 15W-40 for seasonal flexibility.
Heavy-Duty Engine Oils
Extended-drain protection for diesel engines operating under high load, high dust, and extended idle conditions.
- API CK-4 / FA-4: Backward-compatible with CJ-4 and CI-4 PLUS.
- OEM Approvals: Cummins CES 20086, Detroit Diesel DFS 93K222, Volvo VDS-4.5, Mack EOS-4.5.
- Soot Handling: Enhanced dispersancy for EGR-equipped engines (API FA-4 for 2017+ EPA GHG Phase 2).
Biodegradable Hydraulic Fluids
Soil-safe, water-safe formulations for equipment operating near sensitive watersheds, organic farms, and riparian zones.
- Biodegradability: >60% in 28 days per OECD 301B.
- Toxicity: Non-toxic to soil microbiota per OECD 216 (soil micro-organism nitrogen transformation).
- Performance: ISO VG 32, 46, 68 with anti-wear additives meeting ISO 11158 (HH, HL, HM categories).
- Labeling: EU Ecolabel candidate; EPA VGP compliant for incidental runoff.
Field-Proven Agricultural Resilience
Engineered to excel where conventional lubricants fail, our field-tested formulations protect heavy machinery across extreme conditions. From ensuring seamless -30°C cold starts to maintaining rock-solid viscosity under scorching peak harvest loads, this advanced chemistry resists heavy dust contamination and extends drain intervals by up to 25%—keeping large-scale operations moving forward.
Field Tested Durability
Our products are proven in the dirt. Trusted by large scale farming cooperatives to maintain uptime and reduce wear in demanding conditions.
