Here is the rule of thumb for JD mower engines. On non-pressurized systems use a straight 30 weight in the summer. On motors that have full pressure systems you can run 10/30 or 10/40 in the summer.
Any engine with an oil filter is a full pressure system by the way. Some of the early Kawasaki JD engines didn't have filters but were full pressure systems anyhow. They just skimped on the parts!

It should be just fine. Not much difference between that and 10w-30. The 10w-40 just runs a little thinner to prevent it from bogging in cold. Hopefully you aren't mowing your lawn in the middle of winter, though...

yes it will work fine in it,most manufacturers now recommend 10-w-40 any way in them it lubricates a little better and will stay on the moving parts a lot better,but it wont hurt it to run it in it,i use it in an older one ,i think mine is around 16 years old now,and still running good,the old saying about john Deere's, is true nothing runs like a deere,good luck with it.

You run the risk of voiding your engine warranty if it is not the grade they recommend.
