Second service results Kioti Dk50 se hst

[liberty2701]

I just completed my second HST service at 450 hrs. The first service was done at 50 hrs with new filters and Amsoil ATH 5w30 in the hydro. Then I did the filters again at 250 and now fluid and filters at 450hrs. I had an oil analysis done at around 400 hrs. I also enclosed here a picture of the main drain plug with the magnet. It had pretty large metal shaiving on it. Is this normal?



Report from Blackstone
"Thanks for the notes. Copper is a bit high in this sample, but it's probably just wear-in material
that's still washing out. It usually takes a few oil changes to get it all out, so it'll probably drop once this oil is
changed. Universal averages show typical wear for a hydrostatic transmission after about 590 hours of oil
use, and other wear metals match up nicely. No contamination was found and the viscosity was on the mark
for a 5W/30 grade oil. This oil can stay in place another 25-50 hours. Check back after ~400 hours on the
next fill to build trends."

Manufacturing cuttings?
I changed my hyd filters at 50 hrs.
My first hst oil change will be @ 450 hrs to sync up with engine oil changes.

I though about. This is my second oil change. I figured this would be gone after the first change. There has to be others out there who can chime in on their own service results.
