I understand that the grass on the lawnmower corrode the metal.
Would hosing down the mower after every use, be bad idea. Or would
the overspray water create problems in the engine?

It depends on a lot of things. Higher quality mowers that used sealed
bearings in the blade brake and possibly the wheels do not do well with
being hosed down. Hot sealed bearings when hit with cold water can
actually suck a small amount of water in past the seals. That will kill
the bearings pretty quickly. Cheaper mowers that don't use high quality
bearings can generally withstand a wash down when hot without any problems.
Where you direct the water is important. Avoid the cables, a tiny amount
of water in a cable will cause it fail quickly. Avoid the air filter and
the engine as much as possible. Try to just wash the mower deck.
