    Spraying Equipment

  • 1. What application rate do I need to use on my pasture with my new Econopak?
     

    We can advise you on how to apply the desired water rate, but when it comes to the chemical
    concentration rate you need to refer to the label on the container (if in doubt – contact an
    agronomist for advice).

  • 2. Can I buy a Silvan tractor mounted sprayer from my local Rural Merchandise Outlet?
     

    No. Silvan Farm Machinery is only available from authorised Silvan Master Dealers. Please refer to the dealer locater for your closest Master Dealer.

  • 3. How long is the warranty period on Silvan Spraying Equipment?
     

    Silvan warrants its spraying equipment for a period of 12 months.

  • 4. How do I determine the air chamber pressure of a diaphragm pump?
     

    The air chamber pressure is relative to spraying pressure. Refer to the operators manual for more information. Ex factory pressure is approximately 80psi.

  • 5. How do l clean my Silvan sprayer?
     

    Tanks should be flushed out with at least 10% of the tanks capacity with clean water. Be sure to flush all booms, spray guns and other componentry. This should be repeated again with clean water & Silvan All Clear tank cleaner. See the All Clear label for directions.

  • 6. How many PSI is equal to 1 bar?
     

    1 bar = 14.503774 PSI (14.504) psi

  • 7. Why has my diaphragm pump oil level dropped? It doesn't have any external oil leaks. I topped up the oil level twice and now the oil level has dropped again.
     

    The most common cause is the diaphragms have gone soft and stretched causing the oil level to drop. Diaphragms will require replacement ASAP.

  • 8. Is there a Hopper grid cover and Hydraulic control available for the PL-500 spreader?
     

    Yes. Part number 642010 for the cover and 619010 for the hydraulic control.

  • 9. What is the difference between hammer blades & Y blades on our mulchers?
     

    The hammer blades tend to give a flatter finish (like a mower), they do though require more horse power to run. The Y blades are more suited for inter-row mulching (vineyards / orchards),
    This is for a couple of reasons. The Y blades are double-sided so when you wear the leading edge out you can turn the blade around. Also the Y blades leave a slightly corrugated finish which allows the mulched matter to break down a lot faster because there is more air flow under the mulched matter.

  • 10. What is the difference between a slasher and a mulcher?
     

    A slasher only cuts the grass and then tends to leave the cut grass in wind rows – the wind rows take a
    long time to break down and during that time the soil tends to spoil underneath the windrow. A
    mulcher on the other hand mulches the grass to a very fine consistency and then it distributes it evenly
    across the width of the mulcher, so no wind rows are left and the grass breaks down back into the soil
    quickly.

  • 11. Will a SP150 / PL-500 / TSP-500 / SX-500GALHOP or an oscillating spreader (SQTF) spread lime or Gypsum?
     

    No. The problem with lime is that it tends to “cake up” and becomes almost solid, so a couple of things
    will happen. Firstly the product won’t spread and secondly there is a good chance that something will
    break inside the spreader because they aren’t designed for that type of product. The only machine that
    will successfully spread products like Lime & Gypsum are belt spreaders and they
    are generally much more expensive than the generic PL-500 (Seed & fertilizer spreaders).

  • 12. Where can I purchase Silvan Farm Machinery?
     

    Silvan Farm Machinery is only available from authorised Silvan Master Dealers. Please refer to the dealer locater for your closest Master Dealer.

  • 13. Why can’t I buy machinery direct from Silvan?
     

    Silvan is a Wholesaler. We rely on our dealer network to pre-deliver machinery and provide after sales support.

  • 14. How long is the warranty period on Silvan Farm Machinery?
     

    12 months on Nobili, DCM and Sitrex. 24 months on Breviglieri products and Silvan Slasher drivelines.

  • 15. Why do the blades or hammers wear quickly on my Nobili Mulcher?
     

    The working position is too low so the blades or hammers are touching the ground. Adjust the height of
    the rotor in relation to the ground.

  • 16. Why does my Nobili Mulcher vibrate excessively?
     

    A. The blades or hammers are worn or broken. Replace the worn or broken parts.

    B. The blades or hammers are locked by pins. Clean and grease or replace pins.

    C. The rotor balancing is not correct. Check the weight of the blades or hammers to ensure they are the
    same.

    D. The rotor bearings are worn. Remove and replace bearings and seals.

  • 17. Why is my Nobili Mulcher's rotor speed low and cutting poorly?
     

    A. The belt tension is poor. Adjust the belt tension according to the operator’s manual.

    B. The belts are worn. Replace the belts.

  • 18. My Breviglieri rotary hoe or power harrow is not operating to the correct working depth.
     

    Readjust the skids or roller as required, decrease the working speed or, in very hard soils, it may be necessary to make multiple shallow passes to achieve correct working depth.

  • 19. My Breviglieri rotary hoe or power harrow is causing excessive soil crumbling.
     

    Raise the rear hood or roller depending on the application or increase the working speed.

  • 20. My Breviglieri rotary hoe or power harrow is causing inadequate soil crumbling.
     

    Lower the rear hood or roller depending on application, decrease the working speed and avoid working in soils with too much moisture.

  • 21. The rotor(s) is clogged or obstructed on my Breviglieri rotary hoe or power harrow.
     

    The soil is too wet to work properly, the machine needs to be lifted to clear the blades, reduce the working speed and avoid working in conditions with high crop residues or grass in un-worked soil.

  • 33. What is the purpose of a pressure switch on the end of a 12V Pump?
     

    When the spray lance or spraying apparatus is turned off & the flow stops, pressure builds up in the hose/pump, which turns off the Pump at a predetermined pressure.

  • 34. Can the Selecta range of Diesel units be used to transfer petrol?
     

    No, the 12V pumps used on our Diesel transfer range are not rated for Petrol and the tanks are not suitable for the use of petrol storage either.

  • 35. What is the benefit of fitting a regulator kit to my sprayer?
     

    Fitting a regulator kit allows you to apply the desired pressure suitable for the nozzles, assists in achieving accurate spray calibration results and also allows for the recirculation of fluid back into the supply tank.

  • 36. Can I use my Fire Fighter as a Sprayer?
     

    No, Silvan does not endorse this practise. Residual chemical in a tank or line may act as an accelerant in a fire and can also pose health risks to those using a fire fighter if they are exposed to those chemicals.

  • 37. What capacity pump do I need for my boom sprayer?
     

    Use the following formula.
    Pump output required (L/min) = (Application rate (l/ha) x Speed (kmh) x Boom width (m))/600. Then allow 20% of the tank volume extra for agitation.

  • 38. How can I check that my tractor speed is accurate?
     

    Use the following formula. (3.6 x Distance covered in metres)/seconds = Kmh
    Example: Distance covered = 100 metres. Time taken = 60 seconds. Then 3.6 x 100 / 60 = 6 Kmh

  • 41. Can I use PL and SX Spreaders to spread lime?
     

    Powdered lime will not spread well with a spinner type spreader, options to buy a prilled type lime or upgrade to our Rondini Osolating type spreader while not doing a perfect job on powdered lime it is a better option for small scale applications.

  • 42. Are parts available for 12V pumps if something goes wrong?
     

    Yes, contact your local Silvan/Selecta dealer, they will be able to help you find the parts you need.

  • 43. Can I use a boom with my Redline trailer?
     

    Yes. Our Redline trailer kits can be ordered with a boomless jet kit which has been designed specifically to match each models pump outputs, ensuring an even pressure and distribution giving you a 2m (55lt) and 3m (100lt) spray width. If you require a broader spray width please talk to your local dealer about our Spotpak range.

  • 44. What length of hose can I run on with the 7L / 100 psi smoothflo pump?
     

    Up to 30m of 10mm ID hose.

  • 45. Do I need to run a regulator with my 12 volt pump if I want to boom spray?
     

    Yes, it’s ideal to run a regulator to ensure correct spray pressures, please refer to Accessory Fitment chart on page 43 of our Rural Lifestyle Guide Booklet. Also, the DDP-552A Smoothflo pump has a built in regulator internal bypass. So you wouldn’t need to add a regulator for this pump.

  • 46. What type of nozzle can I run in my hand gun?

    Refer to our Accessory Fitment chart on page 43 of our Rural Lifestyle Guide Booklet for information regarding boom applications and pump sizing.

  • 48. I need to replace my diesel tank pump, which pump is best better ‘DieselPower’ or ‘DieselPro’?
     

    Both pumps are imported and made to world class specifications. High volume users tend to use the Piusi pump as it deliveries 45L/min compared to 40L/min with the Dieselpower unit.

  • 49. Why is my 12 volt pump turning on and off all the time – spray is pulsing?
     

    Adjustable nozzle screwed up restricting flow, excessive restriction in nozzle or hose or nozzle size too small. Also the spray gun maybe be blocked by chemical for example, also check that everything for flow side of the pump is not blocked. Pump is pulsing as cannot disperse enough fluid quickly enough to match the flow specs of the pump.

  • 50. What does the pressure switch on my 12 volt pump do?
     

    When the gun is turned off and the flow stops, pressure builds up in the hose and pump, the pressure switch then turns the pump off at a predetermined pressure.

  • 51. Can I use a Triam or Jetpro gun on LOW Pressure (eg. 12v Pumps)?
     

    Yes, it will still work efficiently, but due to lower flow rates, ensure the nozzle size suits your application.

  • 52. Why does my Triam gun leak from the nozzle?
     

    If it is a gun you have had for a while and been using then most likely the main seat (the rubber washer under the nozzle cap) is worn/damaged and needs replacing. If it is a brand new gun then check the washer has been installed correctly and the gun seat (green plastic dome) is adjusted correctly.

  • 53. Can I use Access and Diesel mixture in a Spotpak or Redline 12v sprayer?
     

    No, as the 12V pumps are not compatible with diesel.
