Direct Pivot Parts has bubbler pads in stock and ready to go. Brand new at $3.80 each.
Great for soaking the soil under your drop hoses without leaving a trenched out line from water pressure. Great for Corn, Milo, Cotton, Alfalfa, Sod, and all winter crops.
These are ideal to install next to your pivot tires to keep your pivot tracks/tires dry and prevent your pivot tires from trenching out. Some local farmers have them on all their drops.
I have used them myself and they perform great.
Come and grab them (and all your pivot parts) at Direct Pivot Parts TX in Hart, TX or I can ship them to your door. 806-414-5166 or 308-391-1214
