@WiestJr It's for checking moisture in your fields. Depending on how hard or how easy it is to push in the ground it gives you an idea how wet the field is.
Thank you @costcocanada for giving up on straws and having a nice lid. For all the people that think a paper straw is acceptable you're wrong. They fucking suck ass.
@LowBoomLowDrift It's important to have someone who really knows the machine come out with it. Salesmen can always tell me how something should work but can rarely show me when I ask for help.
