Using the Master Gardner as a Trailer
If the Master Gardner will be used with a garden tractor a trailer tongue can be attached to the sprayer for
towing. Attach the trailer tongue (Item 8, figure B) to the sprayer frame (Item 7, figure B) aligning the
holes and using the pin and hair pin (Item 3, figure B).
Setup
Charging the Battery
1.) Obtain the battery charger (Item 27, figure B). To charge the sprayer battery locate the charging
connector that exits the switch housing located on the upper handle (Next to the on/off switch). Plug
this connector into the connector on the chargers and then plug the charger into an AC wall outlet.
2.) Allow the charger to charge the battery until the light on the charger turns green. A green light
indicates the battery is fully charged. A discharged battery could take as long as 24 hours to recharge.
3.) Never allow the battery to discharge completely. Doing so will damage the battery and void
warranty.
Testing
1.) Always test the sprayer with clean water prior to spraying with a chemical mixture. This will
allow the sprayer to be inspected for leaks and repaired before expensive chemicals are used.
Using the front Deflector Nozzle
1.) Four things must be considered before spraying with the boom.
1.) How much chemical must be mixed in the tank?
Refer to the chemical label to determine the chemical mixture
2.) Rate of spray (gallons per acre to be sprayed.
See the Tip Chart below to determine the gallons per acre. The chart will also show the
speed used when spraying.
3.) Speed traveled (M.P.H.) while spraying.
Refer to the Tip Chart and Speed Chart below for MPH.
Determine Gallons per Minute
Once you know how much you are going to spray then determine (from the tip chart) the spraying pressure
(PSI) and the spraying speed (MPH). The pressure is preset by the pump, typically between 30 to 35 psi,
but it will vary depending on the percentage of charge left in the battery. If precise chemical metering is
desired, then the battery should be fully charged and a flow rate should be measured at the nozzle. After
the battery is fully charged, obtain a bucket and place under the nozzle. Turn the valve on to begin
spraying water into the bucket while timing. Allow the sprayer to run for 1 minute and then turn off
sprayer. Measure the amount of water within the bucket to obtain the exact GPM of the pump and nozzle.
