Same here HH, it's been a pretty dry spring. I stopped mowing with my little lady bug mower with the high lift blade and bagger and just use the one with the mulching blade. We are expecting rain the next few days, hopefully it will head your way. I'd hate to see you not be able to use your new machine.
I just checked the weather forcast, there's a "...chance of heavy overcast next Friday followed by possible thunderstorms the following Monday..." BUT, on the good side, I'm using the heck out of the new machine, I just don't have the mower deck on it. I've been TLB'ing some and struttin' it around the neighborhood.
I've got 4 yards of compost mix topsoil coming next Friday so that will ensure I will need to water with the well when I do any lawn patching. Wifey really hates having to wait until after dark to do laundry and bathe in the creek (she really freaks out when she sees the headlights coming), but the lawn does come first and I don't mind turning my underwear inside out every so often...!
