Common Questions About the John Deere 750
For those new to the John Deere 750 or compact tractors in general, there are often several common questions and concerns that arise. Here, we will address some of the most frequently asked questions:
1. What Type of Engine Oil Should I Use?
Using the correct engine oil is crucial for the longevity and performance of the John Deere 750’s engine. The recommended oil for the John Deere 750 is typically a multi-grade, 15W-40 diesel engine oil. Always check the owner’s manual to verify the correct oil type, as it can vary based on climate and usage conditions.

The John Deere 750 features a manual transmission with a dry clutch, which requires periodic adjustments to maintain smooth operation. If you notice that the clutch is slipping or becoming difficult to engage, it may be time for an adjustment.

• Adjusting the Clutch: The clutch pedal can be adjusted by loosening the nut on the clutch linkage, allowing the pedal to move freely. Ensure that the clutch pedal has approximately 1.5 to 2 inches of free play before it begins to engage.
  
• Transmission Adjustment: If the tractor experiences difficulty shifting, you might need to adjust the transmission linkage. This can be done by checking the linkage rods for wear or misalignment and adjusting them accordingly.
  

3. What Is the Recommended Maintenance Schedule?
Routine maintenance is key to keeping your John Deere 750 running smoothly. While the specific maintenance intervals may vary, a general schedule would look something like this:

• Every 50 hours of operation:
  • Check and change the engine oil.
    
  • Inspect and clean the air filter.
    
  • Check the hydraulic fluid level and top up as necessary.
    
  • Grease all fittings and moving parts.
    
• Every 100 hours of operation:
  • Replace the engine oil and filter.
    
  • Inspect the PTO shaft and replace if worn.
    
  • Check the coolant levels and hoses for leaks.
    
• Every 200 hours of operation:
  • Replace the fuel filter.
    
  • Inspect the brake system and adjust as needed.
