Welcome to Lawnsite. There are lots of people here that will undoubetedly answer your request. I think you could have got alot of answers on the regular forum and mayby a moderator will relocate it for you.
I don't have a major mowing operation with lots of Z's and handhelds but I manage pretty well on a small scale. I just keep track of the hour meters.
I have to apologize for responding without really answering your question but I spent all day yesterday "WINTERIZING" my equipment and thought about how nice it would be if I didn't have to put it away for the winter.
Hopefully you will not have to winterize your stuff
Hey, Are ya hiring winter help?????
