The Hiniker has a few advantages, in my opinion.

If you are looking for ST with dry fertilizer, it is a turn key operation. Hiniker provides everything, including the NH3 cooler and controller, if needed.

Short coupled. About 21 feet long. IF you are applying NH3 simultaneously, you aren't driving a freight train.

The cart wheels are also the lift assist wheels for the unit, so it is easy to back up.

Easy, no tool adjustments.

Works great in spring or fall applications and in a variety of soil types and conditions.

Handles high residue applications very well.

6000 cultivators can be retrofitted to make them into ST units.  Saves money!
