I'm thinking this is a mix of mowing the field, versus mowing the lawn.
Mowed the lawn(s) 5 times now, ours and the two neighbors that asked me to, and they pay for the gas.
It the constant cold left a little early and the cold dips didn't go below freezing. But not as much rain as usual, because this is "If it's not raining, you're mowing season". Normally, your legs get tired treading water and trying to keep the mower from pulling your head under the water.
On the plus side, I got the zoysia cut down to tennis ball fuzz height and have been keeping it there a month waiting for the annual power raking from the middle of May to the middle of June.
