I managed to have a good look at the mower.
As mentioned, the mower wheel bearings are all shot, especially the front ones that have now collapsed causing the wheels to lock up - the water blast probably dislodged what little was holding the balls in place smile.
The front axle is almost rusted through and will require replacing or rebuilding; maybe the axles too. as the wheel bearings are locked on.
The air filter was chocka with oil, debri and dirt.

Replace with a genuine B&S or a generic filter? Any suggestions?

After a good clean and dry.
There is spark and fuel yet the engine refused to start. Over the weekend my Son visited - a few good pulls of the start cord and the pull drive thingy pulled free - the securing rivets gave way.

This mower is put to one side for a while as a load of health related issues have dumped on our life.
I will post next when I am able.
