I've talked to Bob Posthuma (owner of Greater Earth Organics) and he was telling me about his new compost tea sprayers that are coming out this Spring. He makes the GeoTea (250 gallon compost tea machine) that a few people own here on Lawnsite. So here's a few pictures of his units.
Bob said that they should be up on his website very soon.
For the 4 Wheel Tote Sprayer:
The total price for the 4 wheel cart is $5250. That includes the sprayer with 200’ of ½” hose and the 25’ wide boomless nozzle with a manual
control for the nozzle. An electric solenoid valve to control the boomless nozzle is available for $250 more.
