Grand Golf Course talks on new Jacobsen Spray Unit

Written by:

The Jacobsen Raven Envizio Pro II XP Sprayer has been hitting all the right notes with superintendents across the globe since its release last year.

Among those impressed by Jacobsen’s new addition is Rodney Cook, superintendent of 20 years at the picturesque Grand Golf Course on the Gold Coast.

Since receiving the Raven GPS equipped machine last December, Cook and his team have been using it non-stop and are impressed by certain functionalities, particularly the versatility of the spray nozzles.

He believes it is more user-friendly than conventional machines and outshines them in several key areas.

We really like it. Going from an old conventional sprayer to the GPS technology has been good,” Cook said.

On a normal everyday sprayer, you calculate the ground speed of your machine, the width of the boom, and how many nozzles on the boom to give you your outputs.”

The old types of machines require you to turn your triplet nozzles, and then it’s a volume thing e.g. blue nozzle puts out 400 L/ha, Yellow puts 600 L/ha and a red nozzle puts out 800 L/ha etc.

The Jacobsen XP E-Pro has twin nozzles on the boom, back to back. Using the Capstan Sharpshooter, we can change the nozzle droplet micron size on the run if it gets too windy without leaving the operators seat, in conjunction with the Raven GPS the output stays at the desired rate, unlike the previous triplet set up, where you had to stop spraying and reselect nozzle size whilst accepting a change in volume output”.

The Raven GPS unit has been well tested and used in agriculture throughout the world for the past 20 years, With the Raven Envizo II Pro we punch into the computer a volume we want to spray at and whether you’re spraying at 5 kilometers an hour or 10, the Envizio Pro II adjusts the volume to the output selected prior to spraying.

Another key feature of using GPS guided spraying is the ability to save superintendents time and money.

Cook said he is surprised by the amount of product the GPS system has saved across its 10 months in operation so far.

The GPS system maps the area already sprayed, “It knows where you have sprayed and you can see it on the map on your screen, so if you go over an area that you’ve sprayed, the nozzles will not come again eliminating over application,” Cook said.

If you go over an area and there is half a square metre that you haven’t sprayed, one nozzle will turn on for that half a square metre and the rest will shut down so you cannot under apply.”

It has saved us a hectare of spray product on our fairways per application.”

Cook said the machine has allowed both he and his grounds team to operate more efficiently and complete jobs in a timely fashion.

Time wise, we’ve probably gained half to three-quarters of a day per fairway spraying application,” he said.

Instead of staying a set speed of 5 kilometers an hour with conventional sprayers we can now operate between and 5 and 12 km/hr depending on terrain.

The Jacobsen EPro XP Sprayer can be used as more than a vehicle for dispensing pesticides and other liquid products.

Cook said this versatility is particularly valuable during renovation periods.

It’s not a dedicated spray machine, we can take the spray rig off and put on top dressers, core harvesters or us it as a utility vehicle that can carry a up to 1.5 tonnes of material.

We take it off for two or three weeks a year so we can use it for something else. That is a saving as well.”

Now that we’ve finished renovations it’s basically a dedicated sprayer.”

Cook is also pleased by the EPro XP’s ability to operate in the kind of conditions that superintendents are expected to cope with on a daily basis.
