Will be Restocking Many Tired 21"'s this Season. Choices are: New Design Honda HRC....I Really Despise the Old HRC but the New Model Has some Major Improvemenrts (Untested) 26" eXmark Metro....Looks to be Low on Power for Mulching (Untested) 21" Proline/Metro's/Kaw....Tried Tested and True. There are No Other Options. Commercial Lawnboys are Dead to Me Since the Briggs Replaced the Duraforce...Snappers Can't Mulch and are Second Rate Prolines....JD doesn't have a Commercial Unit any More. & No Quick 36"'s or Belt Drive 32"'s or Billygoat 33"'s Thank you Very Much.
