Just did this one myself for the first time. Looking for hints to make it easier/cleaner? The oil drain plugs let the oil just run down over the tires, very difficult to catch in a pan. Manual specs UDT2 or 80-90 gear oil. Do both really work OK in this application? The UDT2 is lighter and easier to handle, especially in cold weather. Looking for any comments you more experienced guys might have.
Servicing front axle on 3901 HST 4WD

I formed a "funnel" with aluminum foil, to catch the oil before hitting the tire, to direct oil into a catch bucket... In colder climates, UDT is fine but I'm a gear oil guy. Stickier the better...
I hacked up a large butter tub to fit under the drain plug and sit in/on the inside of the rim of the tire. Then I put a hole in the side of it near the bottom to drain the captured oil into an oil pan. It was a pretty clean operation.
I have a L2501 but pretty sure the 3901 is similar In this regard. I got a cheap aluminum pan (the kind you place a turkey in) and put it up against the tire. Then, propped a funnel with long throat (8” or so) under the drain plug and placed the end of the throat against the edge of the pan so it wouldn’t move. Worked like a charm. Nothing spilled. i replaced the fluid with 80W-90 gear oil.
Plastic, aluminum can, cardboard all make quick disposable funnels to drain pan.
Switched to Lucas synthetic 75w90. Surprised how dark the OEM sudt was at 400hours on the B26. Almost time for the next change.

4.8 U.S.qt. is in the manual... it takes a while for it to seep into all the nooks and crannies.... pretty sure the L2502 is the same as mine and L2501 (I looked that up just to see...)
The 80/90 is better, especially if the tractor is not used regularly. I just did a total fluid and filter change - Hydrolic - Front end gear - engine - fuel filters and air filter.
Took hours to refill the B26 front axle. 5 quarts. Oil has to seep thru bearings.
Took days for M59, 11 quarts. Temperature dependent so a good summer time job.
