120 x 10 = 1200.
Larger inverter than that may be needed. Keep the 12 *volt cables as fat,
and as short as possible. Run more 110 volt AC power cord if you need to.

I have some trees down in the woods that I need to cut up. I can get the
tractor to them and would like to know what size inverter ( how many
watts) do I need to run the saw.
Thanks for any info

1200 watts divided by 12 volts = 100 amps. 120 ahr battery = less than *one
hour operating time. What kind of tractor? If that's big enough, you still
need a couple thousand rpm.

Interesting point...
Why is the OP looking for an inverter rather than a small
gas powered generator or even a gas powered chainsaw...
I feel that the "application" here is needlessly complicated
by user error and over engineering...
