When you do the HST filter on the no step side, it has a magnet in it. Don’t be alarmed at the metal you find. It did its job. The metal is just casting flash and slivers from machining.I picked up the filters and oil today since they are original. I'll change those when I get a chance, its been raining non stop so when its sunny out...I'll get it warmed up good and change them.
This was mine at 125hr.
Congrats on the new to you tractor.
