Kawasaki’s K-Tech 15W-50 4-cycle engine oil contains a proprietary "thermally stable zinc" (ZDDP) anti-wear additive package, but Kawasaki does not publish an exact numeric parts-per-million (ppm) rating for its zinc content.
I have a John Deere X324 machine and usually have it leveled so it will cut as high as possible
so I get a really high cut to keep my small pasture grass/weeds under control.
If I bring the adjusting nuts to high the mower deck will bump the frame and it's difficult to unlock
