Bedrock J20C
PREMIUM TRACTOR
HYDRAULIC FLUID
Universal tractor hydraulic and transmission fluid for tractors and equipment that call for a J20C fluid
Bedrock J20C is a universal tractor hydraulic and transmission fluid for tractors and equipment that call for a J20C fluid. On these machines one fluid serves the hydraulic system, the transmission, the differential and final drives, the wet brakes and the clutches, because they all share a common sump. Bedrock J20C is formulated for use in tractors that specify J20C for that shared-sump service.
A universal tractor fluid does several jobs at once. It carries hydraulic pressure to the loader, the three-point hitch and remote cylinders, lubricates transmission gears and bearings, lets the wet brakes grip without chatter and lets the PTO and transmission clutches engage smoothly. A fluid of the J20C type is made for that mix of duties, through long seasons of field work and the months the machine sits parked.
Use Bedrock J20C where the operator's manual names a J20C fluid or a universal tractor hydraulic and transmission fluid of that type. It is the farm and ranch grade of the Bedrock hydraulic line and also serves loaders, backhoes and utility equipment whose manual calls for the same fluid. Dedicated hydraulic systems with their own reservoir take Bedrock AW 32, AW 46 or AW 68 by the grade on the decal, not a universal tractor fluid.

Applications
- Farm tractors whose hydraulics, transmission and wet brakes share a common sump and whose manual calls for a J20C fluid
- Loader, three-point hitch and remote cylinder circuits fed from the tractor's common reservoir
- Power-shift and manual tractor transmissions, differentials and final drives that specify a J20C fluid
- Wet-brake and PTO clutch systems on tractors and self-propelled farm equipment that call for J20C
- Backhoes, utility tractors and ranch equipment with a shared-sump hydraulic and transmission system that specifies J20C
- Hay, forage and harvest equipment hydraulics where the maker names a universal tractor fluid of the J20C type
- Shop top-off and change-out stock for a mixed fleet of tractors whose manuals name J20C
Performance
- Protects transmission gears, final drives and hydraulic pumps against wear under field loads
- Formulated to meet the J20C requirements for wet brakes and clutches, so brakes engage firmly without chatter and clutches shift smoothly
- Resists oxidation and thickening through long seasons of field work and summer heat
- Protects steel and yellow-metal parts against rust and corrosion during work and storage
- Controls foam and releases air so the hydraulic pump stays primed through loader and hitch cycling
- Keeps hitch and loader controls responding evenly as the fluid warms from start-up to working temperature

Frequently asked questions
Which machines take J20C?
Tractors and equipment whose operator's manual names a J20C fluid or a universal tractor hydraulic and transmission fluid of that type. These are usually machines where the hydraulics, transmission, differential and wet brakes share one reservoir. Check the manual or the decal by the fill cap, and ask the Bedrock dealer if the manual is missing.
Can I use J20C instead of AW 46 in a hydraulic system?
Only where the equipment maker allows a universal tractor fluid. A dedicated hydraulic system with its own reservoir normally calls for an anti-wear hydraulic oil such as Bedrock AW 46. A tractor with a shared sump needs the universal fluid because it also lubricates gears, clutches and wet brakes. Fill by what the manual names.
My tractor's wet brakes chatter. Will J20C fix that?
Fluids formulated to meet J20C are designed to work with the wet brakes and clutches in a shared sump, and a fluid of the wrong type is a common cause of chatter. If your manual calls for J20C, drain the old fluid, change the filter and refill with Bedrock J20C following the maker's procedure. If the chatter continues, have the brakes inspected.
