I had and early 80's 843. there is a fine filter in the middle hose wright above the hydraulic pump i believe .when i owned the 843 i remembered it was noisy especially when turning .I had both hydro motors rebuilt with no help. most likely than not its old age in the hydrostatic pump and that could get costly.If its running properly i would just live with it

Most of them groan and moan at lower engine rpm.. How does it sound at 2/3 throttle or so? If it goes straight forward and backward with very little noise and just noisy when turning it may be normal.
