CK2610 HST Sluggish/dying when cold

[Kwehme09]

You are confused. Maybe you didn't catch that I solved my issue by changing the HST oil to AMSOIL. I was just suggesting to the OP that he could do the same and find a better/suitable oil too. Also, the rad temp has nothing to do with the HST fluid temp. Only the pump pushing it around is what heats up the HST oil. Dutchy

Will a block heater help warm the HST oil?

I know this is an older post, but my NX4510 will react in a similar way when it is cold. It was my understanding that the engine would run a little lean (less power) until the engine reaches operating temps to protect it? Once it is warmed up, there are no issues. A block heater will help in getting the engine to operating temps sooner. Also, I believe that putting in a good cold temp hydraulic fluid helps as well. I use a local Co-op fluid that has a pour point of minus 50 Celsius. I am considering a heating pad on the hydraulic sump on those colder days to help warm up that side of the machine as well.
