Agricultural Lubricants for Tractors and Farm Machinery
From tractors and harvesters to loaders and groundcare equipment, agricultural machinery works through long hours, heavy loads and busy seasonal periods. Rock Oil’s agricultural lubricants and ancillary products help operators maintain equipment across the farm, with AGRI-GUARD at the centre of the range.
AGRI-GUARD®: the agricultural range
AGRI-GUARD brings together lubricants for tractors, harvesting equipment and associated machinery. Choose from engine, transmission and hydraulic lubricants, with specialist products for other farm equipment.
- Engine oils: AGRI-GUARD LS 10W-40 provides a low-SAPS option, alongside AGRI-GUARD 15W-40. Select the grade and specification required by the engine.
- Tractor transmission and hydraulic oils: UTTO 10W-30 is formulated for systems incorporating wet brakes, clutches and differentials. UTTO ZF 10W-30 and synthetic UTTO SYN WB 10W-30 provide further options.
- Multifunctional tractor oils: SUTO 10W-30, 10W-40 and 15W-30 offer STOU options where the machinery specification calls for a multifunctional lubricant.
- Off-highway transmissions: TO-4 oils in SAE 10W, 30 and 50, plus TRANS 80W-140, cover further transmission requirements.
- Hydraulics and specialist equipment: BLUE HVI 46 supports hydraulic applications; ATV 10W-30 is for four-stroke quad bikes, and MILKING MACHINE OIL serves milking-machine vacuum pumps.
Supporting products across the farm
Complete the main agricultural range with fluids and maintenance products for cooling systems, hydraulic equipment, groundcare machinery and the workshop.
ULTRA-HYD hydraulic fluids
ULTRA-HYD extends the hydraulic offering with HLP, high-viscosity-index and long-life fluids, alongside zinc-free, synthetic, biodegradable and fire-resistant options.
Hydraulic options for tractors, loaders and attachments cover changing outdoor temperatures and specialist environmental or fire-resistance requirements.
KOOL-GUARD coolants
KOOL-GUARD includes IAT, OAT, NOAT and HOAT coolant technologies, supplied as concentrates or ready-to-use products for relevant applications.
The right coolant technology and dilution support engine temperature control and corrosion protection. Compatibility depends on the equipment specification, rather than colour alone.
GROUNDSMAN for groundcare
For smaller horticultural and groundcare equipment, GROUNDSMAN includes semi-synthetic 2-Stroke oil, 4-Stroke 10W-30 and SAE 30 engine oils. Chain and guide-bar oils include mineral and biodegradable vegetable-based Bio options.
Bring mowing, trimming and chainsaw maintenance into the same farm servicing programme, with dedicated oils for engines and cutting systems. Two-stroke equipment requires the manufacturer’s specified mixing ratio.
Greasing and workshop maintenance
Greases support routine servicing of bearings, joints and other greasing points across farm machinery.
Support everyday agricultural maintenance with products for cleaning, assembly and lubrication, including BRAKE KLEEN, COPPER ANTI-SEIZE, WHITE SPRAY GREASE and OPEN GEAR CHAIN & WIRE.
Match each product to your machinery
A farm can operate several generations of machinery with different engine, transmission, hydraulic and coolant requirements. Check the manufacturer’s specifications and service guidance for each machine; suitability and approvals apply to individual products.
