I feel this need to confess--I'm a slow learner. I purchased my JD Model 670 a couple of years ago. When I piled up 50 hours and prepared to change the engine oil for the first time, I was horrified to discover that the drain plug was only finger-tight! It could have vibrated off!
More recently I saw that I was approaching 150 hours and decided that it might be a good idea to change the transmission/hydraulic system oil--even though I've got a gear tractor without a loader or other hydraulic-driven implements. Anyway, I crawled under and discovered that the drain plug on the transmission was also only finger-tight. It too could have vibrated off! Also, when I checked the rubber hose from the transmission vent, I found it plugged tightly with mud-dauber mud. And when I removed the fine-mesh screen (the basic Model 670 doesn't have a cartridge filter) I found a bunch of insect wings, body-parts, etc. My tractor sat on the dealer's lot for awhile before I acquired it. Apparently the wasps had crawled up the vent tube, died and were decapitated.
The moral of this story is: When you get a new tractor, check it over!!
By the way, I found no evidence of metal shavings or such.
