Context: I have a Husqvarna 1830HV snowblower. The chute is controlled by steel cables a lot like bike brake cables. They work almost exactly like bike brake cables, in fact, except for the fact that they are solid, so the cable can both push and pull, and there is no recoil spring, so the cable stays in a fixed position.
Trouble: It being winter, snow gets all over the machine. When it gets above zero, the snow melts and gets into the rubber casing around the steel cable. Then when it freezes again, the cable jams in place.
Solution: I don't know. Any ideas?
