Many languages distinguish between inclusive and exclusive first-person plural pronouns (“we”). The inclusive “we” specifically includes the addressee (“you and I and possibly others”), while the exclusive “we” specifically excludes the addressee (“he/she/they and I, but not you”). This grammatical distinction is called “clusivity.” While Semitic languages such as Hebrew or most Indo-European languages such as Greek or English do not make that distinction, translators of languages with that distinction have to make a choice every time they encounter “we” or a form thereof (in English: “we,” “our,” or “us”).
For this verse, translators typically select the exclusive form (excluding the landowner).

Like many languages (but unlike Greek or Hebrew or English), Spanish uses a formal vs. informal second-person pronoun (a familiar vs. a respectful “you”). Spanish Bibles all use only the informal second-person pronoun (tú), with the exception of Dios Habla Hoy (DHH) (third edition: 1996) which also uses the formal pronoun (usted). In the referenced verses, the formal form is used.

See also the use of the formal vs. the informal pronoun in the Gospels in Tuvan.
Like many languages (but unlike Greek or Hebrew or English), Tuvan uses a formal vs. informal 2nd person pronoun (a familiar vs. a respectful “you”). Unlike other languages that have this feature, however, the translators of the Tuvan Bible have attempted to be very consistent in using the different forms of address in every case a 2nd person pronoun has to be used in the translation of the biblical text.
As Voinov shows in Pronominal Theology in Translating the Gospels (in: The Bible Translator 2002, p. 210ff.), the choice to use either of the pronouns many times involved theological judgment. While the formal pronoun can signal personal distance or a social/power distance between the speaker and addressee, the informal pronoun can indicate familiarity or social/power equality between speaker and addressee.
Here, Jesus is addressing his disciples, individuals and/or crowds with the formal pronoun, showing respect.
