I am a retired engineer and recently purchased a small hydroseeder that pulls behind a 4-wheeler (ATV). It was designed for golf courses to do patch work, but it works really well for me to establish wildlife food plots, and will work for seeding the pond I am about to construct. I have some small equipment (bulldozer , backhoe, etc) and I am considering doing a bit of wildlife habitat establishment for a few other landowners. I can give you info on the hydroseeder if you contact me.

As you probably already know, watering is critical, even if the hydroseed mix includes gel for water retention. But if you are putting in a pond, you may have an advantage for watering.
