? about HST/Hydraulic Oil for L3901

One thing to note about reinstalling your FEL is that if it sits in the sun disconnected you may have to release pressure before the fittings will snap together. I use an old metal rod to push on the center section to release a bit of pressure.

As stated already, buy your oil at Walmart (Rotella synthetic T-6 5w-40 is about $20/gallon) and your filters should be Kubota, bought online or at your local dealers. I don't have a local dealer close by I like, so I let my fingers do the shopping and find the best deal for a complete filter kit). BUT, for a L3901, you want to use Kubota's SUDT 2 in the hydraulic system, especially if you are running an HST tractor. It is worth the extra cost, which isn't much over 400 hour change intervals.

I've never felt the need to drop my loader in the 250 hours of use I've had it. I dump the impliment on the SSQA but can't be bothered to dump the loader.

I like the Super UDT2 fluid for the cold Colorado winters & reasonably warm summers. It's quieter than other options. One problem though is its crystal clear & they put in an awkward hidden sight glass. I could never tell if it was over or under filled. I finally got a small jar of John Deere red hydraulic dye. Put in half the jar & now my Super UDT2 looks like pink ATF. I can easily see the fluid level in the sight glass.

I had to top mine up when I added 3 spools & my TnT. Extra hose & cylinders took a few quarts to fill. Had some leaky fittings here lately & had to add another quart which put it to the very top of the sight glass.
