JCB Power Selected for Envirofix Hydro Seeder
When the manufacturers of the Envirofix hydro seeding equipment received a commission for their biggest machine developed yet, they turned to a single JCB industrial diesel engine to deliver the power required by this massive machine.
The basic operation of a hydro seeder is quite straightforward. The tank holds a mixture of seed, fertiliser and tackifiers all held in suspension in water. Agitators within the holding tank ensure that the elements remain in suspension and well mixed while a mulch pump draws the mix from the tank to spray onto the area being seeded.
A contractor associated with the natural gas terminal construction at Gladstone in Queensland placed an order with Envirofix for a 13,000 litre hydro seeder. As the biggest unit built to date had been around 4,000 litres, the new unit presented a massive challenge.
“Our client already has four seeding machines from Envirofix,” said company MD Richard Hurley. “The challenge was to take the basic engineering principals that make our systems so successful, and apply them to a larger application. This involved us developing some unique features in our new machine.”
The tank has three hydraulically driven agitators, there are two turret guns which can deliver the mixture simultaneously and there are six CCTV cameras located on the truck to give the driver the best all round view of operations.
At the heart of such a large unit is a power system that drives all the on-board systems, in this case the agitators and the pumps.
“I had planned on using a Yanmar diesel engine as I had experience with the brand and was impressed with the reliability and support service of the brand. However, there was inadequate horsepower available and the people at Power Equipment recommended that I use a bigger JCB engine.”
The requirement from the Envirofix engineers called for 120hp from a turbo charged diesel engine.
Power Equipment is the authorised agent for both the Yanmar and JCB brands. After carefully checking the requirements for this unique application, Power Equipment recommended the JCB DieselMax 444.
The JCB DieselMax 444 engine is housed in an enclosed engine compartment with excellent access on both sides for servicing. It is a 4-cylinder, 4.4 litre powerhouse boasting 4 valves per cylinder with high torque at low speeds. This JCB engine is rated at 89kW at 2200 rpm
The JCB DieselMax 444 is one of the very finest engines in its class on the market and carries a market leading warranty policy. Quiet operation is an added feature given that this unit operates with a number of operators in close proximity to the engine. “We certainly looked at other brands but nothing matched JCB and Power
Equipment for reliability and product support,” Richard Hurley said. The installation was very straight forward. The JCB DieselMax 444 engine, hydraulic pump and controls all came together as designed. The JCB engine draws diesel fuel from the main fuel tank on the carrier truck, further simplifying the installation.
“Now that the unit has been thoroughly tested during commissioning and in the field with the customer, we could not be happier with the JCB diesel engine. It operates magnificently and performs its job with ease.”
“We are very happy with the JCB DieselMax 444 engine and the entire rig is mine spec compliant.”
Up at Gladstone the new Envirofix hydro seeder is being used to seed bare earth on construction sites to prevent erosion across vast areas and in turn control sediment running off to the ocean and ultimately the sensitive Great Barrier Reef.
