How do I Change Kubota 7500 Hydraulic Oil?


The Kubota B Series 7500 tractor is a small-framed tractor that you can use for a variety of jobs. Certain components of the Kubota 7500 tractor, such as the loader and rear three-point hitch, require hydraulic oil to move them via pressure in the hydraulic oil hoses. Over time the viscosity and additives in the hydraulic fluid will wear out; change the oil every 1,000 hours.

Things You'll Need

  • Tractor hydraulic oil
  • 5-gallon bucket
  • Wrench set
  • Funnel
  • Park the Kubota 7500 on a level location. Shut it off.

  • Go to the rear of the Kubota 7500 tractor.

  • Unscrew the hydraulic oil fill stick located above the drawbar on the back of the tractor.

  • Slide the bucket under the rear end of the tractor.

  • Find the hydraulic oil drain plug in directly in line with the hydraulic oil fill cap below the tractor. Unscrew the hydraulic oil drain plug with the proper sized wrench -- usually 5/8-inch if it's never been replaced.

  • Tighten the hydraulic drain plug back in tightly after all the oil has drained out into the bucket.

  • Stick the funnel into the hydraulic oil fill hole. Add fresh hydraulic oil slowly. Continually check the hydraulic oil level with the oil fill stick.

  • Remove the funnel and tighten the hydraulic oil fill stick back into place.

Tips & Warnings

  • Take the used oil to an auto repair shop to dispose of it -- most usually charge a small fee.
