Hi Grant,

You should not use gear oil in that transmission/hydraulic system as it is far
too heavy, don't forget you are using this oil for the hydraulic system mainly
and if its too thick it will not work and if you have cold weather it will go
like treacle. You can use Multi-grade 15W/30, that is suitable for Canada
winters too, we have quite a few people who have changed over to this and they
say its great in winter, no waiting for the oil to warm up a but before you can
use the tractor.....I will send you some more info about it........John
