εἴ τις γεωργὸς ἀγαθὸς προθυμηθεὶς γενέσθαι καὶ εὖ σπείρων καὶ εὖ φυτεύων, ὁπότε καρποῦσθαι ταῦτα δέοι, ἐῴη τὸν καρπὸν ἀσυγκόμιστον εἰς τὴν γῆν πάλιν καταρρεῖν
First, I think there is an omission of εἴη after τις,
Second, δέοι is a modal attraction, instead of generalizing subjunctive.
No omission of εἴη. Read the sentence again. “. . . the same as if someone, eager to be a good farmer and planting and raising the crop well, when the time came to harvest, were to let the crop fall back onto the ground ungathered.” Or something like that.
It’s not necessarily a general condition. ὁπότε is often interchangeable with ὅτε.
Thanks, now I can see it, even so, this is a modal attraction, is it not?
Yes, δέοι is attracted to the mood of ἐῴη.
great, thanx.
