Toro 21199HD — 30 in. TimeMaster, Home Depot Rental

The rental version of the 30 in. TimeMaster — Toro’s own parts page titles it "TimeMaster 30in Lawn Mower (Home Depot Rental)", which is what distinguishes it from the 21199. All five of its published parts listings have been opened, and the blade changes once: Toro lists the 15.4 Inch Atomic Blade kit 20120P up to 406999999 and the 15.4 Inch Hi-Lift Replacement Blade Kit 20122P from 407000000. Neither number’s product page says it replaces the other, so these are two different blades rather than one superseded — and on a machine that gets rented, which blade Toro lists is worth checking against your serial rather than against the model number you were handed.

Cutting width: 30 in.
Production runs: 5
Parts listed: 10
