THE DIFFERENCES IN
Turbo Turf makes three series of mechanically agitated
systems the HYBRID, the HARV-E and the HARV. These
units are available in three tank sizes, 500 gallons, 750
gallons and 1000 gallons.
THE PADDLE ASSEMBLY AND MIXING SYSTEM
Many in the industry saw the idea of a paddle,
(mechanically agitated) hydroseeding system using a "PLASTIC'
tank as having great potential. Early attempts by others
involved hanging a bearing on the plastic tank and
did not work well. Turbo Turf took a whole new
approach to the problem. The bearings and agitator
shaft are supported completely by heavy structural steel
supports and the tank is used for nothing but holding the
material. There is no stress whatsoever on the tank
and the entire mixing system would run without the tank even
being present. Not one problem has occurred with
this system with units now in heavy use for several years.
The system is so reliable Turbo Technologies has introduced a
20 year tank warranty (see below for details)
Turbo Turf's "HYBRID" is another whole new
approach to hydro seeding equipment design. It is both a
mechanical (paddle) and a Jet agitated unit. It is equipped with an
13 H. P. Honda electric start engine that is directly
coupled to a 3" X 3" high volume centrifugal pump with
an operating pressure of 72 PSI and a GPM output of 333 GPM.
There are no clutches, belts or gears in the simple pump drive.
There is a separate 8 H.P.
Honda electric start engine on the 500 gallon unit or a 13 H.P.
Honda electric start engine on the 750 & 100 gallon units that
uses a simple and reliable double belt drive to power the
mixing paddle assembly. Turbo Turf's HYBRID uses the
most simple and trouble free drive possible.
The platform and tower gun are standard
equipment on the Hybrid units. The hose reel shown in the
top photo is an option and available with either electric or
manual rewind. Standard equipment includes hose
holders on the side of the tank. The Hybrid units
all have free flow couplings on the hose which minimizes the
possibility of plugging problems since they have no restrictions
where they are coupled.
The hybrid units can use paper, wood or blended
mulches and will mix slurries that are as thick as those used in
most any paddle type system. Clean up on a hybrid
unit is the best and easiest of any unit on the market.
The jets allow you to flush the unit completely clean in
seconds. Trimming far easier than with many
other paddle units. Should something happen to the
paddle drive the unit is capable of operating completely as a
jet unit. The aggressive paddle agitation
allows you to drop full bales of mulch in the tank with no
breaking up of bales required.
One of the major problems faced with
mechanically agitated units is rust. Turbo Turf's POLY
tanks eliminate that worry. Some users of mechanical
units apply the fertilizer in a separate step because of the
corrosive nature of Nitrogen. The poly tank means It is never a worry
with Turbo Turf. Most manufactures of Mechanical
units try to minimize the problem. Several use an
epoxy coating which helps a lot but will crack in time and allow
rust. Others make their tanks from stainless steel. That
is better yet, but where the corners are welded the protection of
the stainless steel is lost and that is the very spot where
corrosive materials build up in other units. No
other system totally eliminates rust like Turbo Turf's poly
The "HYBRID" units combine the light weight,
outstanding trimming ability, near clog free performance, easy
clean up and one man operation of jets with the ability to
handle materials needed for challenging jobs and the ability to
use full mulch bales without breaking them into chunks.
HARV AND HARV-E
The working components of the HARV and HARV-E are identical.
Both are fully hydraulically driven mechanically (paddle)
agitated units. They combine the best features of
some other units but also offer features that no other machine
The HARV and HARV-E both have a 25 HP Kohler Command Pro
engine on the 500 gallon units or 30 H.P. on the 750 & 1000
gallon sizes that is
directly coupled to a two stage hydraulic pump.
There are no belts or chains in the drive system.
The pump powers both the paddles and the hydro seeding pump.
The paddle speed can be controlled hydraulically and the paddles
can be reversed so in the unlikely event mulch or some
obstruction jambs the paddles, they can be reversed in seconds
to clear the problem. The hydro seeding pump is a
Bowie 2" gear pump (positive displacement) that is unequalled
for pumping thick slurries through long hoses.
The main working parts of the HARV and HARV-E are identical.
The difference between the two are that the HARV includes a full
platform with a multi position turret gun, and electric rewind
hose reel and a flush tank plumbed to give advantages no other
- The full sized platform gives you the ability to carry
more supplies to the job with you.
- The turret gun can be relocated in seconds from left to
right to back. No one else offers this feature.
- The flush tank is plumbed to both sides of the pump.
Since the pump is also hydraulically reversible you can blow
out most suction line clogs or clean the unit in a fraction of
the time normally needed.
- The standard Electric reel can be equipped with radio
remote control eliminating the need for a hose man.
- Units can self fill from a pond or stream (with optional
Picking the right machine for you!
1. Any hydro seeding unit with a gear pump
is a little more difficult (but not impossible) for one man to
run. Someone planning to seed alone may want to look
harder at a Hybrid unit with it's centrifugal pump.
2. For a landscape installation
application the trimming ability of a Hybrid unit is far
superior to the trimming ability of any unit with a gear
pump such as the HARV and HARV-E.
3. Those who expect to use very long
lengths of hoses (over 200-250 feet) may find the gear pump on
the HARV and HARV-E to be an advantage. Those who
expect to use a tower gun a lot may find slightly better
performance with the centrifugal pump on the HYBRID.
4. Those expecting to do a lot of erosion
control jobs using BFM products may find the Gear Pump on the
HARV units to be the better choice however the Hybrid will also
work for these applications.
5. Those who expect to seed using
sprigs (plant parts) should look only at the HARV units because
of the positive displacement (gear) pumps.
