Paul, At one time you were talking about working with soil guard. How did that turn out? Would you feel confident spraying BFM's through your T60?

Do the same principles apply with BFM's as do regular hydraulic mulch in that...if you want a thicker BFM, you simply cover less area per tankful? Or do BFM's mix thicker in the tank....necessitating specialized equipment above and beyond a unit like your Finn?

And finally....does anyone know what refinements if any Finn added to their recent Series II units over say a late 90's model (non Series II)

We have worked with one BFM (Bonded Fiber Matrix) There are a few tricks to using a BFM, spray at 1/2 rate in one direction say with the nozzel horizontal wait for it to dry a bit then apply with the nozzel vertical. What you are looking for is a solid covering, which means no voids or thin spots. This is not something that you can just blow and go. You can get close with home made BFM Just use 100% wood fiber mulch, locking fibers(we use Finn) and 4 times the normal tack. We have no problems mixing 250 lbs of this at one time in our T60, and it sprays fine. We do shoot the seed seperate from the BFM. so it is a 3 step process.

Our T60 is a II unit it uses a direct drive no belts like the older units, plus it has a electric clutch instead of levers. Gives the operator much better control. Larger units use hydo power giving them even better control plus the option of two pumps.

I wish I had pictures of our test site, didn't have the camera at the time. We did a slope less than 1:1 and had a 5" rain 3 days after the shoot. No wash out and the seed grew fine. Hardest part of doing BFM's is the cost, people think that since you are shooting it the think it should cost the same as regluar hydro-seeding. Your costs are almost 3 times the cost of regluar hydro mulch plus your shooting 2500 to 3500 lbs per acre!

Wow...great information!

Paul, what year is your T60?
