Also keep in mind that the strainer assembly is plastic (at least it is on my 2310)-- be careful not to over-tighten when re-assembling; let the o-rings do their job.
And to answer your previous question "Is the hydro static oil and hydraulic oil all together?" Yes. It's all from the same sump -- power steering, hydrostatic transmission, hydraulic systems for FEL, BH, MMM, etc.
Other than operating PTOs, the engine's main job is to drive the hydraulic pump; pressurized fluid is then routed to various devices through the valves/control knobs, levers, steering wheel valves and go-pedal(s).
Hope this helps your understanding; these are amazingly capable --and useful-- machines. Just try not to ever use the word "fun" when talking about the tractor... it gives people the wrong impression...
I知 one of the few who are downsizing . I sold my 1540 non hydro for the GC2600 , I found the 1540 a little big for my application , I was always damaging the yard when doing Chores. Though I will probably miss the bigger tractor at times I am looking forward to the hydro drive , cutting grass and especially the front mount snowblower!
