John Deere Z840A Mower Blade FAQ
Is a close blade length good enough for the John Deere Z840A?
The blade length found is 19 in (483 mm). Close is not the same as correct. That is a common lawn tractor blade length range, but it still needs the right center hole, sail/lift shape and deck fitment. Match the OEM number or old blade before buying
