The Farm King 1684 BackSaver pairs a 16-inch tube with an 84-foot length for high-volume truck unloading and bin filling. It has a swing-away intake, scissor-lift undercarriage, and an included reverse kit.
The main auger runs from a 1,000 RPM PTO. The hopper reaches beneath the trailer while the scissor lift sets the discharge height; its mover and winch should be chosen to suit how the unloading area is arranged.
| Specification | Value |
|---|---|
| Tube diameter | 16 in. |
| Auger length | 84 ft. |
| Drive | PTO |
| PTO speed | 1,000 RPM |
| Intake | Swing-away hopper |
| Undercarriage | Scissor lift |
| Reverse kit | Included |
| Manufacturer minimum power | 170 HP |
Farm King’s 2025 guide gives the 1684 a 170 HP minimum. Match the tractor’s PTO shaft and hydraulic service to the supplied equipment, and check that the bin inlet and unloading area fit the auger’s working range. The receiving bin or other equipment also needs enough capacity to accept the grain being delivered.
