The gearboxes on King Kutter equipment PREVIOUSLY were shipped dry. Now, all gearboxes are shipped with gear lube in them. That change happened about two years ago. HOWEVER, it's always a good idea to check the level of the gear oil in both gearboxes on any tiller, prior to the first use, and every use / or eight hours of use.
The gearboxes are filled manually, by American folks just like you and me. And just like you and me, they can and do sometimes make a mistake. So it's possible that one or both gearboxes might get missed.
All King Kutter tillers are set up and ready to use. Depending on tractor, you may need to shorten the driveline. Other than that, depending on where you buy it, you may need to un-crate it, because all King Kutter tillers are shipped in wooden crates.
I hope that helps! Have a great day, and thank you for your interest in King Kutter products!
