50hr service

[TripleR]

Many report that the HST runs quieter (and better in winter) with SUDT.

5030? Manual tranny? Yes, UDT probably perfectly fine. But for an HST, especially if used in winter, I would go with SUDT from everything I've heard.

My L5030 HSTC has 1200 hours on it and ran UDT all its life. Like I said, winters here in SEMO aren't very bad. I use our tractors in the winter.

I somehow wound up with 5 gallons of SUDT and will put it in my 2660 this fall since I have it, but don't believe I will buy any more.

Dealers in my area don't even keep it in stock.

My brothers are mechanics and we have tried about everything including synthetics.
