A spreader (100) includes a bucket (102), a handle unit (128) connected to the bucket, a pair of wheels (118) attached to the bucket configured to move the spreader, and a plurality of holes (130) disposed at a bottom portion of the bucket. The spreader further includes an adjustment mechanism (132) having an adjustment element (134) slidably mounted on the bucket and disposed over the holes, wherein a movement of the adjustment element is configured to selectively vary a degree of opening of the holes. The adjustment mechanism further includes an end stop (153, 716, 816) configured to create a mechanically insuperable impediment (155, 407, 507, 607, 724, 824) for restricting the movement of the adjustment element (134, 708, 808) towards the full-open position of the holes (130, 706, 806). The end stop (153, 716, 816) includes a mechanical element (157, 718, 818) configured to shift a position of the impediment (155, 407, 507, 607, 724, 824) to selectively restrict the movement of the adjustment element (134, 708, 808) towards the full- open position of the holes (130).
