Hi Kev.
I can only say that both of mine were. They both had two drain plugs. I can’t say what the “Green” tractors do. After all, they just use Yanmar sailboat auxiliary motors so they could depend on some one siphoning the oil out from above. Orange tractors tend to have easier and more complete maintenance set ups while Green tractors have more cup holders and a better color keyed interior. ;-()
I once had oil drained out of a 4.3L Vortec motor for over a week while patching the oil pan. Nothing happened although I did disconnect the distributor and crank the engine over for a while before starting the truck.

No oil will do no damage if the engine isn’t started.
Truth is, there’s enough residual oil clinging to the honing marks in the cylinder walls, entrapped in the lifters, entrapped by heir own surface tension in the small spaces between the bearings and their corresponding surfaces, etc. that an engine unstarted for a week should require no special preparation before restarting. The “Long Term Parking” lots at airports all over the country have cars that have been there for over a week. Some need jumpstarts because they had weak batteries to begin with or they had parasitic drains or the dome light was left on, but the engines are fine.
You state the owners manual says it has a 5.3 Quart capacity but all the sources I can find list the capacity as 4.4 to 4.6.
There is a difference between how much oil the car maker has to put in a dry engine and how much oil you need to change it.
Usually the owners manual lists how much oil you need to change it. I don’t know why yours doesn’t
If other sources didn’t confirm your experience that it only takes 4.6 quarts I would think you had a bad dipstick, but as it is, I wouldn’t worry about it.
My Brothers Daedong,has two drain plugs in the sump and its a prechamber engine(makes it hard to start in warm weather,why prechamber?someone suggested it was because of fuel quality in third world countries)I think on that tractor.its made with 2 drain plugs because the sump is actually divided for clearance purposes,another funny thing is that some of its parts come in Kubota boxes
I am retired, too, the same mountainbike. And, that’s all I ever wanted to be.
Assuming it does its job reliably and for the life of the engine, it looks like a nice piece of engineering to me. I see in it a single cast housing that integrates multiple functions eliminating the need for hoses & clamps & extra assembly, good structural support for the structure, and simplification for the installation. These attributes simplify assembly, reduce the opportunity for errors, reduce procurement costs, inventory, and WIP parts-handling costs, and eliminate manufacturing steps. In short, It appears to incorporate all the design features that the Japanese so successfully made a part of their design culture.
The chimp that did this has clearly learned Japanese design practices.
I’d agree if it had a core value.
The cost would probably be higher.
got recycle value,actually that thing looks well engineered to me,I dont sweat multi fastners,the torque sequence is easy to figure out,have to agree about the hoses,hoses are generally a weak link-Kevin
