[Ford-ferguson] Thin out the hydraulic fluid in cold temps?

[Jason]

As long as your tractor is gear drive, I would think you could go with a 10W 
hydraulic fluid for the winter which will help.   I think 134 is closer to 
20W but that's just a guess.

As far as for something that will flow better year around, what i would do 
is look for a synthetic oil and I would contact Amsoil up on Superior WI. 
They've manufactured synthetics for a long time and they're small enough you 
might be able to talk to someone that can make a good recommendation for 
your application.

Good luck,

Jason

I have a 1957 Ford 860 with the piston-type hydraulic pump.

I've put the standard New Holland Multi G134 hydraulic fluid in.

In these cold winter temperatures (sometimes down to -5 or -10F), the
hydraulic lift is very slow until it warms up, maybe 1/2 hour or 45 min.
of operation.

Can I safely thin the hydraulic fluid, using kerosene or something
similar, to quicken the warm up period a bit?

IS there a better fluid that will be good for cold temps as well as
summer temps (summer is usually < 90F).

Thanks for any help.
