Engine turns very slowly
Mower has been sitting all winter. Engine turns over very slowly, (once every 3 seconds), battery is brand new. Compression problem or starter?

I agree take both spark plugs out and spin the engine. Could be hydro locked.
If that doesn't work and since it is an older mower a valve adjustment might be in order ~!~!

Welcome! A new battery is only as good as the connections, including at the battery, solenoid, ground, etc., so that's where I would start, but, to Cheese's point, some more details could definitely be beneficial.

Brand new battery means nothing, no one here knows when it was installed.
Has it been charged up?

My first though was just what Pedro said. Connections. Make sure your cables are clean & are making good connections at both ends.... hot & ground cables.... both ends.
It could be a starter issue but I'd start with the battery cable ends. If the cables are getting a good connection & you are SURE of that, & it still is slow to turn over, try using jumper cables to jump from the battery to the starter.. then try from your car battery to the starter.
It could be that the cables are corroded under the plastic coating on the cables. Therefore, you'd need new battery cables.
Same with the solenoid.....
As well, I wont rule out a bad battery, although its a new battery. Put a hot charger on it if you have one & try it. Or Just use jumper cables from your car battery to the mower battery.
Good luck....

Digital Gauge on mower says 12.7 Volts when I turn key. After a few key turns it drops to about 12. I will take out plug and turn it over. Will jump to starter as well and see what happens.

Still just a guessing game, we have no idea what you have. Briggs, tecumseh, kohler, kawasaki, water cooled, air cooled, single cylinder, twin, gas, diesel, etc... There is a detailed answer for this problem for each, but until we know what we're dealing with we are guessing.
