Doing maintenance on my father In laws M4900. Noticed the hydraulic fluid on the dipstick is milky white from condensation and want to drain and refill all hydraulic fluid. Can anyone confirm how many hydraulic drain screws the M4900 has. When under the tractor I believe I see 3 but want to confirm. Also. Once completely drained and new filters on will all new hydraulic fluid be pored into the oil fill above the PTO & beside the dipstick? Or are their other oil fills for the gearbox? I don’t have access to the owners manual so any assistance would be appreciated. Thanks

Welcome to OTT
I once owned a M4900 for several yrs but I can't remember # of drain plugs. Yes hyd filler plug is by pto. Both hyd filters had removable,cleanable magnets designed to catch loose metal particles.
