The white smoke is oil - did you overfill the oil ? if you tipped the machine your air filter could be full also - if this is an old machine it could be ready to throw a rod but not enough info from you to tell

My lawnmower started to flutter till it died while shooting white smoke. Any suggestions?

The white smoke points to the oil and fouled spark plugs.
Make sure the oil level is according to the gauge.

White smoke from engine on Start up

Sounds like the turbo. Have you ever changed the turbo? If not, I would bet on that. If you've changed it but have more than 60-80k miles on it, same.

Possible electrical problem?

Diagnosing something from a description is far from an exact science, but this is what it sounds like to me may have happened. If your battery was not tie down it could have gotten against something hot or moving (like a pulley), or what ever was rattling may have created a spark somehow and caused the battery to exploded, either way the battery fluid spashing onto hot metal could explain the cloud of white smoke, as you did not mention seeing any flames.

Change spark plugs now smoke

I can't see the smoke you're talking about - but I suspect it is oil burning off. Did you see / apply any oil to either the threads of the block or plugs or drip or spill something on the exhaust manifold / pipe? Did you torque the spark plugs in properly? A loose plug can result in poor compression and ignition and allow some exhaust gasses / smoke to escape. The engine sounds to be running well, so I suspect that the small amount of oil burning will be burnt off completely very shortly.

First there was occasional white smoke, loud engine rattle, cutting out on full throttle and poor starting. the injectors were serviced but the engine has refused to start.

White smoke is usually an indication of a blown head gasket. Check you oil (dipstick) for a milky looking color instead of normal oil. Pull a spark plug and look to see if there's moisture on it. All of the symptoms you've given point towards a bad head gasket

Blown head gasket or not?

check oil dip stick for water/antifreeze and radiator for oil in antifreeze but usually alot of white smoke-steam from tailpipe usually indicates head gasket blue smoke means oil black smoke carbon

Lawn mower keeps cutting off

from the sound of what you are describing the piston/rings/cylinder are damaged in some way shape or form this causes compression loss in the engine, and allows oil to enter the combustion chamber, in this case a new lawnmower would be in the near future
