OPERATING INSTRUCTIONS
BOOM WITH 10" NOZZLE SPACING: Two times the
number of fluid ounces collected equals the gallons
per acre (GPA) output.
Repeat this procedure two more times, collecting
water from a different nozzle each time. Use the
average number of ounces collected from the three
nozzles to determine the gallons per acre output of the
boom at the set pressure and selected RPM and gear
setting. Note: If the ounces collected from any nozzle
are 10% greater or less than the ounces collected
from any other nozzle, it is a sign of wear and all the
tips on the boom should be replaced.
To determine the amount of product to add to the
spray tank, divide the capacity of the tank by the
number of gallons of water per acre (GPA) to
determine the area, in acres, that can be covered with
a tankful of spray.
Example: 200 Gallon Tank divided by 20 GPA = 10
acres covered per tankful.
Multiply the application rate of the product per acre
times the acres per tankful and add that amount of
product to the tank through the strainer basket. The
tank should be one third filled with clean water with the
sprayer running under full agitation. After the product
is completely mixed, you would fill the tank to the
proper level with clean water.
Example: 2 quarts per acre x 10 acres per tankful =
20 quarts or 5 gallons of product to be added per
tankful of clean water.
To decrease the output: Adjust the pressure
regulator to a lower pressure that still maintains
the spray pattern; or increase the speed of the
tractor (truckster); or change the nozzle tips to a
smaller size.
To increase the output: Adjust the pressure
regulator to a higher pressure that still maintains
the spray pattern; or decrease the speed of the
tractor (truckster); or change the nozzle tips to a
larger size.

Tips on Spraying
a.Mixing Dry-Bagged Products for Sprayer Use
Dry-bagged products should be pre-m ixed with clean
water in a five gallon container to form a slurry. The
sprayer should be one third filled with clean water and
running under full agitation. The slurry should be
slowly poured into the sprayer through the strainer
basket. After the product is com pletely m ixed, you
would fill the tank to the proper level with clean water.\
b.Use of the MTD Pro Chemical Lawn Gun
Determ ine the application rate in gallons per 1000 sq.
ft. from the product label. D ivide this figure by your
spraying pace in m inutes per 1000 sq. ft. to determ ine
the proper flow rate for the gun in gallons per m inute.
Use this figure to select the proper nozzle and then
calibrate the sprayer, to spray this flow rate. To use
the gun, hold it in your right hand (if you are right
handed) with the hose form ing a loop, running under
your right arm to your back, over your left shoulder,
down across your chest and around and out from your
right side and back to the sprayer. Holding the hose in
this way takes the weight of the hose off of your right
arm and allows you to pull the hose with your whole
body and not just your arm .
If you are left handed, the above would be reversed.
Sw ing the gun with your wrist so that the pattern is in
constant m otion and covers a swath about eight feet
wide. Start at the sprayer and work into the lawn. W alk
in parallel paths about eight feet apart and m ake sure
your spray pattern slightly overlaps the previous pass.
Keep the spray pattern aw ay from ornam entals, trees
and gardens.
b.Use of the MTD Pro Spray Wand
The M TD Pro Spray W and consists of a ball valve
which controls the width of the pattern, a handle, a
trigger valve which turn's the flow on and off, an
extension, a screen strainer, a hex cham ber which
controls the flow to the tip, a brass tip and a nut to
hold the tip in place. The tip throw s the best pattern at
a pum p pressure of about 40 psi. The tip launches a
fan shaped pattern about eight feet wide with a droplet
size large enough to help avoid drift.
Determ ine the application rate in gallons per 1000 sq.
ft. from the product label. D ivide this figure by your
spraying pace in m inutes per 1000 sq. ft. to determ ine
the proper flow rate for the wand in gallons per
m inute. U se this figure to calibrate the sprayer to
spray this flow rate.
To use the wand, hold it in your hand with the hose
running around your body as described in the section
on the M TD Pro Chem ical Law n G un. Hold the w and
so that the tip is 18 to 24 inches above the ground and
the spray pattern covers a swath about eight feet
wide. Hold the wand steady and lock the trigger on.
Start at the sprayer and work into the lawn. W alk in
parallel paths about eight feet apart and m ake sure
your spray pattern slightly overlaps the previous pass.
Use the ball valve to control the pattern width to keep
the spray pattern away from ornam entals, trees and
gardens.
The M TD Pro Spray W and w ith the high volum e tip is
