Until the moisture dries up — as long as people are still plowing for cucumbers and gourds. A behavioral, observable standard: look around and see what your neighbors are doing.
Fixed calendar deadlines — no ambiguity, no room for self-serving interpretation. Grain fields: Pesach. Orchards: Shavuot.
נָתַתָּ תּוֹרַת כָּל אֶחָד וְאֶחָד בְּיָדוֹ!
"You have given each person their own Torah!" — R. Shimon's sharp critique: a standard that depends on observing what others do is no standard at all. Everyone will claim their neighbors are still plowing, and the law becomes unenforceable.
שְׁנֵי סוּגֵי שָׂדוֹת: Two Field Types, Two Deadlines
R. Shimon distinguishes based on how long the soil benefits from late plowing
שְׂדֵה הַלָּבָן
Grain / unplanted field
עַד הַפֶּסַח
Until Pesach — 14 Nissan
Grain fields are plowed to aerate and prepare the soil. By Pesach the ground is dry — additional plowing no longer benefits the land and would only serve the coming shemittah year's crops.
שְׂדֵה הָאִילָן
Orchard / tree field
עַד עֲצֶרֶת
Until Shavuot — 6 Sivan
Trees have deeper roots and retain moisture longer. Plowing benefits orchards well into late spring — hence a later deadline. The soil around trees stays workable until Shavuot.

Shemittah falls in year 7 — all plowing must be completed in year 6, before the deadlines

הַמַּסְקָנָה — Pesach as a Legal Anchor
This mishnah has nothing to do with the Pesach offering, chametz, or the seder — yet Pesach is the legal fulcrum. R. Shimon uses the festival as a fixed, unchallengeable calendar point precisely because everyone knows when it is. His critique — נָתַתָּ תּוֹרַת כָּל אֶחָד וְאֶחָד בְּיָדוֹ — is a broader jurisprudential principle: law requires fixed dates, not behavioral norms. The same festival that anchors the pilgrim's departure from Babylonia (Taanit 1:3) here anchors the farmer's last plow in the sixth year. Pesach doesn't just mark the redemption from Egypt — it structures the entire agricultural and legal calendar of the Jewish year.
