Proper hydraulic fluid maintenance is critical to keeping your John Deere tractor running smoothly. Hydraulic fluid is the lifeblood of your machine’s hydraulic system, ensuring optimal performance for lift cylinders, drive action, and steering. It also protects key components such as the charge pump, hydrostatic pumps, control valve, and hydraulic pump motors from wear and damage.
To keep your tractor operating at peak performance, we recommend including a quick hydraulic fluid check in your daily pre-start inspection routine. Here's a step-by-step guide to help you maintain the right hydraulic fluid level for your John Deere tractor.

Step-by-Step Guide: Checking the Hydraulic Fluid Level on Your John Deere Tractor
Step 1: Park on Level Ground
Ensure your tractor is parked on a level surface, and lower all implements to the ground. This stabilizes the machine and provides an accurate reading of the hydraulic fluid level.
Step 2: Warm Up the Engine
Run the engine at approximately 1000 RPM for at least one minute to warm up the hydraulic system. Once warmed, stop the engine and allow three minutes for the oil to settle. For the most accurate reading, check the hydraulic fluid when the oil temperature is approximately 45°C.
IMPORTANT: Always turn off the tractor’s engine before checking the hydraulic fluid level. Checking while the engine is running can result in inaccurate readings and potential safety hazards.
Step 3: Check the Hydraulic Fluid Level
Locate the sight glass (A) on your tractor's hydraulic system. The fluid level should fall between the marks on the sight glass, with the optimal level just below the top mark. If the fluid level is below the lower mark, additional hydraulic fluid is required.
Step 4: Add Hydraulic Fluid (If Needed)
If the fluid is low, follow these steps to safely add hydraulic fluid to your John Deere tractor:
- Wipe away any debris or dirt from the hydraulic fluid reservoir cap (B) to prevent contamination.
- Remove the reservoir cap and use a clean funnel to add John Deere Hy-Gard Hydraulic and Transmission Oil.
- Add fluid slowly and check the level frequently to avoid overfilling the reservoir.
Note: Hydraulic systems vary by tractor model, so always consult your owner’s manual for specific instructions for your machine.
Why Hydraulic Maintenance Matters
Regularly checking and maintaining your hydraulic fluid level ensures:
- Full functionality of lift cylinders, steering, and other hydraulic components.
- Protection against damage to critical hydraulic system parts.
- Improved overall performance and a longer lifespan for your tractor.
