I tell ya cohen...
I am a maintenance freak: have the hand pump and a bucket of gear oil to change out the gear oil when it starts getting to the point of needing it... expected I'd need to fill the KK tiller when it came in, but the good folks at Agri-Supply had it covered.
They've gathered dust for a year now, and from what I see will likely sit gathering more until I really see a loss, change in viscosity, or contamination.
I feel I should change it as a preventative measure; it makes no sense to change good oil though!
Check the level & feel of it prior to using it, check the level & color after you use it... if it's still good, run it.
