Bucher 2-Way Bale Spear HPU | 3 qt Steel

PM-3554-0131

In Stock

The Bucher PM-3554-0131 2-Way Bale Spear HPU is a 12V double-acting hydraulic power unit with a 3-quart steel reservoir — the same pump that ships inside our gooseneck and bolt-in bale spears. The steel tank handles ranch life better than poly, and the 2-way circuit drives the spear cylinder both up and down.

Why does the bale spear use a steel reservoir instead of poly?

Ranch trucks live outside year-round and get loaded with everything from hay strings to fence wire. Steel survives cab corner impacts and stray tools that would crack a poly tank. The trade-off is weight — a few pounds heavier — but the durability is worth it on a working spear.

  • 12V DC, 2-Way (Power Up / Power Down) — double-acting
  • 3-quart steel reservoir — built for ranch-truck duty
  • 2,500 PSI operational pressure
  • 1.5 GPM max oil flow
  • #6 SAE hose connections
  • Operating temp: -20°F to 130°F
  • Recommended fluid: ATF (Automatic Transmission Fluid)
  • Same HPU shipped inside the Pierce Gooseneck and Bolt-in Truck Bed Bale Spears
  • Bucher PM-3554-0131 — made in USA, 100% tested

For the bale spears this HPU powers, see the Gooseneck Truck Bed Bale Spear or Bolt-in Truck Bed Bale Spear. For a poly-reservoir 2-way HPU, see the Bucher 2-Way HPU (3 qt Poly).
