I searched past posts but didn't quite get the answer so...I am interested in looking at fertilizing with my ZTR mower. Is the spreader connected to ground speed at all or do you just try to go a constant speed? And...how does lime go through a JRCO or Spyker spreader? Really you should have a drop spreader for lime is there a drop spreader attachment for a ZTR Mower? Thanks for your help.
