Hydraulic Filters

Hoping for an informed comment:

Could I use the same Vanguard 10W-50 full synthetic, instead of the recommended 20W-50, API SL, in the hydro transmission?

The only place on a mower that synthetic oils offer any worthwhile advantage is in the hydros
So a 20w50 full synthetic would be worth the extra $ 30
I use penrite 10W60 because it is readily available & I get it at a discount .
And yes you 10W50 will be fine, just give the tranny a few minutes to heat up during winter
Hydros suffer erosion on the kidney plate as they age so a heavier weight oil helps a bit if it is an old unit .
As for Stens oil filters I use mostly theirs which are actually made in the USA by Champion .
For Japanese threads I use the ones from Roy Grispkie & sons which are mostly Rotary brand , no idea who makes them
Some are marked made in USA others Mexico

Yep, I used Amsoil 20-50 for Hydros when I serviced mine.

Hi All,

Zero Turn Mower, Ferris 48", Part Number 5901740.

1. Dont seem to be able to find a part number for the two hydraulic filters - can you help?

2. B&S parts very hard to get in Australia - can you recomend an alternative to above OM?

Thanks in anticipation.

I'm in Australia too & use Castrol oils in our ZTs - guessing you have a Ferris 400S attached are the applicable Castrol Oils
The Hydrogear ZT3100 is common to many ZTs & any Kubota Dealer should be able supply the filters (ZT3100 is fitted to Kubota mowers, including models Z125E & Z125SKH & Z242KH & Z242KW & Z252KH & Z252KW )

Thanks MBTRAC (Mercedes?) - I am doing up this Ferris for my neighbour who has elected to go for the B&S 15W-50 full synthetic (as per engine recommendation for widest ambient temperature range) I will also use it in the transmission - should give very good service.

I did check out various other oil options (inc Castrol) but was out voted by the owner. The cost of the B&S Synth was comparable to most of the other oils.
