Things Happen.

When you are planting, things are going to go wrong. Sensors will go bad and need to be replaced:



Wires will get ripped apart and need patched:



Drive Chains will disappear and you will install new ones:

Marker arms will come apart at the shear bolt and need to be put back together:

Filters will become clogged and need to be cleaned (no matter how distracting that tornado over there may be.):

It is just how it happens. It is better if you know that going in.
