OK, I've tried this earlier, but maybe if I make it easier to think about.....With a turbo-turf hydroseeding system, how many pounds of mulch should I put in for say a 750 gallon tank? most manufactures suggest 4-5 bales, however some are 50 lbs and others are around 30!

Come on guys! Don't tell me nobody has a hydroseeder in here!

Look at this thread: http://www.lawnsite.com/showthread.php?s=&threadid=31210&goto=nextnewest

Also, remember that at this time of year, guys are busy and some even manage to take a fews days vacation, so be patient, please. We've had some great hydro-seeding discussions here.

With all the possibilities in mulch types and brands I doubt there is any hard and fast rule or any one, "correct", answer. I know that with my little machine (200 gallon) it varies from 40 to 80 lbs per load, depending on the brand of mulch. Try adding material until the pump starts getting "lazy" and having trouble pumping a good stream through the jets. You will be able to see what I'm talking about. Start with 600-650 gallons of water, that way when the mix gets too thick to pump well you can add a little water until the pump works well again. Spray that out with an eye to getting mulch coverage on 80-90% of the soil.

Also, pay attention to what your mulch is costing "on the ground". Sometimes the cheapest material to buy is way too expensive to use. I'm using National Fiber paper and it's the highest priced per bale. But it mixes so much faster that I figure I can put down an extra 5,000 feet over the course of an 8 hr day. Had a hell of a time getting the local supplier to understand that there is more to cost of application than material prices. They were going to stop carrying National Fiber because nobody was buying it but me as it "cost too much".

Is your Turbo Turf the high performance model with bigger pump and the bale buster jet? Without the bale buster I'm not all that impressed with the way TT mixes. I helped another seeder when he used his 300 TT the first time and it was WAAAY slower than my home grown 200 in terms of area per hour, mainly due to slow mixing.

Another hint, I found it handy to "calibrate" a 5 gallon bucket for measuring seed. I marked 5 pound increments on the inside of the bucket, sure beats guessing.

Alan, great tips and great advice, thanks a bunch. I'll try your ideas and to answer your question, I have only a 16 hp Kohler and I do have the bale buster (standard on the 750). I recently purchased this for $5,000 with a 10,000 rated trailer that are each only 2 and 3 years old! As you can see I couldent pass this deal. My heart was set on a L90 from EZ Lawn, but the $24,000 price tag makes me hold off a while. Thanks again!

Our Finn T-60 we run 240-250 lbs per load of 100% wood mulch.

How much mulch per acre are you trying to put down?

I have a Turbo Turf E-500 And Turbo reckomended 100 lb per tank

doing some quick math I come up with 150 lb for a 750 gal. unit.

Turbo Turf also hosts a website. www.I-hydroseeding.com

I hope this helps.

This is if you are using paper mulch !!!!!

Respectfully, 150 lbs. in a 750 seems a little light.

In order to achieve 1500 lbs./acre; the recommended minimum for good grow-in, that batch would only cover 4400 square feet...give or take a few.

How many square feet did the manufacturer's salesman promise you?

I agree, the mulch is thin.

We have a 500 gal. machine and they recomend 100 lbs. per tank.

I can push it to 120 lbs. without too much trouble if I'm running a shorter hose. "under 200 ft."

They claim I can get 6,6oo square ft. per load.

Actually I get about 5,000 sq. ft.

The machine does have limitations but for the price and for a entry level machine. I have no problems with it.

I hope to move up to a larger Finn next spring. A 1000 plus unit.

Actual performance:

120 lbs. spread over 5000 equals...

120/.115= 1,043

1043 lbs./acre

Are you able to cover the ground well at this rate or does some dirt still show?

Manufacturer's Numbers:

100 lbs. spread over 6,600 equals...


658 lbs./acre is definately TOO LOW

I agree 100 lbs per tank is too low. Very thin coverage.

At 120 lbs. per 5000 sq. ft. we get better results and more importantly happy customers !!!

I would like to be put down a thicker slurry but you can only do what the machine can handle.

That's why I want to get the Finn next year !!!

I would like to be put down a thicker slurry but you can only do what the machine can handle.

That's right. I've found that a properly engineered jet agitation machine should handle between 30 and 40 lbs. of material per hundred gallons.

That number is higher with paddle units :D

Fact is though that you can provide an excellent level of service with either a jet or paddle machine...the key is as you said, not to spread the mulch too thin using unrealistic coverage expectations.

Hopefully, I'm not beating a dead horse here but if you have 100 lbs. mixed into 300 gallons (or any size machine for that matter)and wonder how many square feet you can do at the rate of 1500 lbs./acre?

Again we go to the math...the numbers don't (can't) lie:

100/1500 =.067
.067 times 43,560= 2918 square feet.

Now a question for the audience...is it more efficient to cover 2,918 square feet with a three hundred, or a five hundred gallon machine?

It would be more efficient to cover it with 300 gallons, regardless of how big the machine is, would it not?
It still comes down to how thick of a slurry your machine will pump.
Also, have any of you tried the "locking fibers" that you can add to the slurry to increase holding capability on hills?
