Read articles →A step-by-step owner-performed walkthrough of the full hydraulic fluid and filter change on a Kubota L3301, covering all four drain plug locations, both the hydraulic and transmission oil filters, correct fluid type (Super UDT2), and fill quantity (6.2 gallons for HST L3301/L3901). Notably candid about a stubborn factory-installed filter and how to free it. Most useful to L-Series owners doing this job for the first time.
Posted by the DIY My Way channel, which appears to be an owner-operator documenting their own tractor maintenance firsthand.
The hydraulic fluid and filters are changed every 400 hours, though some models specify the hydraulic filter be changed at the first 50 hours, then every 400 hours after.
There are four drain plugs: two on either side of the differential requiring a 14mm wrench, and two more requiring a 22mm wrench on HST transmissions.
For HST L3301 and L3901 tractors, you need 6.2 gallons of Kubota Super UDT2 hydraulic fluid.
If it is the factory-installed filter, paint may act as an adhesive. Cut around the seam with a utility knife, spray WD-40, and it should break loose.
