Garden Hoses vs. Lawn Mower Decks
Comparing 2 standards across 16 specifications. 16 key differences identified.
Residential garden hoses standardize at 5/8-inch (15.9 mm) inside diameter delivering 10–15 GPM, fitted with 3/4"-11.5 NH Garden Hose Threads (GHT). Lightweight hoses measure 1/2-inch (6–8 GPM), while commercial high-flow hoses measure 3/4-inch (18–22+ GPM).
Lawn mower cutting decks standardize cutting swaths from 21-inch walk-behind push mowers for lots under 1/2 acre to 42–60 inch multi-blade zero-turn decks for acreage, mounting blades via 5-point star, 6-point star, or 5/8-inch round center holes.
