All season hydraulic oil?

[DigitalCowboy]

Hello, I a 3535 that I bought last winter. I use it in the winter with a snowblower to clear my driveway and all last winter it always seemed to take an eternity for the hydraulics to warm up enough that I could pick up the loader. I kept it in an insulated garage and used a block heater and still it took a minimum of 5 minutes even on days that weren't that cold. I'm in west-central WI and temps here commonly get into the negatives overnight in the wintertime.

The tractor is nearing 50 hours now and with temps in the 40s I'm already seeing it take a minute for the hydraulics to warm up again. I would like to change the factory oil fill and put in something that will flow a little sooner than this. I use the tractor all year around so it needs to be good enough for summer too, don't want to change the trans oil every season. Is there a good multi-weight oil, possibly a synthetic that would fit the bill? I don't really know what is in there from the factory. Thanks.

Hang in there, someone will chime in about syn hyd fluid. But going to be expensive... I live in Northern Lower Michigan and have a 5035 HST. I am just running Tractor Supply Company [ TSC ] premium hyd fluid [ just regular dino fluid ] and it works fine in mine. I keep my tractor in a pole barn that probably never gets down below 20 degrees in the winter.... have an work area I heat during the day and the cement holds the heat during the night. Tractor sits just outside that area in an unheated space. But have never had flow problems that I could tell.... I think Kabota, amongst others, sells a syn hyd fluid...
