Product Overview
The solenoid pulls the engine's stop/run linkage when the key circuit commands it. Weak pull, failure to hold or a sticking plunger can cause no-start or shutdown problems, but wiring voltage and linkage freedom should be tested before replacing the unit.
Matching catalogs list 1991-2005 Grasshopper 721D2 applications with a Kubota 21 HP diesel and also show related Kubota Z400/D600/V800-family or Cub Cadet applications depending on configuration. Match the full 1753ES number, bracket and linkage before ordering.
