[AT] Hydraulic warm up

[Mike]

Mine has a separate tank on the side for the front end loader, the pump 
is in the front of tractor under the radiator. I wasn't sure if the pump 
spinning would warm up the oil . Ralph, do you recall what type of oil 
you put in your Massey, maybe mine is too thick for cold weather, 
although I don't see the kind of cold you do here in Michigan.

Thanks,
Mike M
