Description
Rebuild a property sprayer around a 45-gallon John Deere tank and the major visible application components already grouped with it. The frame, hose, wand, nozzle, gauge, plumbing, wiring, and labeled 4000 Series pump give the project more of its working layout than a bare tank alone.
The existing John Deere ST43791 pump is labeled 12 VDC, 4.0 GPM open flow, and 100 PSI pressure setting, but it needs replacement. For someone maintaining acreage, fence lines, orchard rows, or other property areas, the assembly offers a clear starting point for configuring a new pump and checking the remaining system.
The tank and components show outdoor wear, dirt, scuffs, fading, and residue. Clean the tank and plumbing, identify any prior contents, install a suitable replacement pump, and inspect the hose, wand, gauge, wiring, fittings, and frame before spraying.
Review the gallery for the included pieces and labeled pump, then plan the replacement pump, cleanup, mounting, and local pickup required for the intended property work.
Condition
Used project condition with outdoor wear, dirt, scuffs, fading, and residue. The existing pump needs replacement. Clean and inspect the tank, plumbing, hose, wand, gauge, wiring, fittings, and frame before configuring the sprayer for service.
