Report on 3320 hydraulic fluid/filter change

[sunnyside360]

My 3720 Operator's Manual specifies 200 hrs or 1 year which ever is first for initial engine/filter change. Listed below is John Deere's reply to my inquiry on this topic for 3720.
Bloomingtonmike's 3320 may be an earlier version specifying first engine/filter change at 50hrs. My 3720 was built in March 2007 and it appears the Operator's Manual was changed.

I will be changing fluid and filters anyways at 50 hrs for peace of mind.

I cleaned the hydro screen and changed the filter and fluid at 50 hrs on my 300. There were shavings and particles.
