I've spent much time searching this forum, NH website, and every other site I can find and have not seen the specifications on NH 134 hydraulic fluid.
I have a Kubota B2410 and am ready to change hydro fluid, filters and screen. Last change several years ago I used Kubota SUDT. I have had power steering loss after about 1.5-2 hours of mowing in hot weather but no loss of hydro function. This has gone on since the previous change, if it did it before I don't know for sure because I bought it with 275 hours and changed the fluids after 1 use. I noticed no problems the first time I used it but I also used a rear mower at that time and suspect it was easier on the system. I had hoped to find Chevron All Weather Synthetic, they used to have it close to me in 5 gal buckets but they don't stock it any longer in southwest Fl so I'm told.
My local dealer is Kubota and New Holland and stocks mostly NH 134 and is currently out of regular UDT but has SUDT. I've been through many of the threads in the past on UDT vs. SUDT vs. Chevron Synthetic and since SUDT apparently isn't getting the job done I want to try something else that might help take temps down or be able to handle higher temps or keep its viscosity better at high temps. I would like to compare UDT specs with NH 134 and have not been able to.
