I_Reason, here's some tips for you
During the pre flight, give each main wheel a good hard kick, if nothing falls off the rest of the aircraft, it's airworthy.
If this is your first ag flying job, you will probably enjoy it but follow Big Nasty's advice and find a seat in an air tractor or thrush as soon as you can. I am fortunate enough to do a few hours in one every now and that's more than enough to remind me how good it is in western built aircraft.
Like most eastern european machinery, they are built for a purpose not for style and comfort.
