Two reasons. One, the hydraulic oil gets thicker when it's cold, and it would help to warm up the excavator for at least 20 - 30 minutes before starting to work. And two, frozen ground is harder to dig in. If warming up the excavator doesn't help, you may want to check if the fluid in it is too thick. To do this, look at what the can says that you have been putting in it, and then look to see if there is a sticker somewhere on the machine to see what the manufacturer recommends.
