Sealed hydraulic units that I've serviced were filled with a silicone
oil having a very wide operating temperature range. The units rarely
leaked and the closest replacement for the factory fill I found was
silicone brake fluid from auto parts suppliers.

The B&S engine has no oil filter. The hydro tranny has no filter either
nor does it require oil changes or maintenance since it is sealed.
The only regular maintenance has been replacing the plugs, oil, and air
It does look like shit, though. Scrapes, dents, cracked plastic body
parts, and a torn seat cover held together with duct tape.
A new seat would cost around $60 (US) but as I have learned, when you
replace a non-essential part just for looks, an expensive essential part
will fail shortly thereafter. :-)
So it was the new paint job my 70's Bolens got that caused the starter
to bite the dust! It looks nice but it doesn't move so well right now.
Got to get the other older (late 60's) gear drive cousin Bolens I call
"Rustbucket" ready with a plow and chains in case we get any snow.
Like others said yes there is some power loss with a hydro but it really
is worth it. I have foot pedal hydro. The further I press the pedal
forward the faster I go, for reverse I use the heel of my foot.
