Swarm of Food Destroyers

Dave has admitted his secret was so secret he had no knowledge of it! Truth is he is such a busy bee that he had some many projects on the go, he couldn't keep track of them. Annoying part, he manages to finish them too. So now I have to reveal mine but want one more day. Today so many hints, you will work it out yourselves.

Sun came out today, as did the silage mowing machines thus removing the last dandelions. Animals will now be busy finding an alternative but shouldn't be too much problem at this time of year and at worst, Dave's Blip today would do. The Blip is of two "worker" (contractor) Deutz's on the left with flashing orange lights & 3 mowers, while on the right a "queen" of the tractor world a Fendt belonging to a local farmer and with only 2 mowers. In the middle is a strip of cut grass: the 3 rows on the left are from one of contractors, on the right 2 rows from the Fendt.
