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.
