Key differences: TS 120 42 in has a narrower cutting deck, a smaller engine and less engine power. TS 120 54 in has a wider cutting deck, a larger engine and more engine power. Objective comparison of stated specs — not a recommendation.
How to read the labels
  • larger / more / wider / faster — this mower has the higher value for that spec.
  • smaller / less / lighter / slower — this mower has the lower value.
  • Labels are directional only; whether more is desirable depends on your needs.
  • Note: a lower deck-gauge number means thicker steel, so for Deck Gauge a smaller number is the more durable deck.
