TETHER SEED CO. 
POWER TRACTION DUSTER 
Carrying and cranking a Hand Duster for a length of time is 
very tiresome for which reason many farmers have trouble in getting 
their help to do a good dusting job. The men either shirk on the 
job or skip over the field thus giving little of the protection sought 
by the farmer to the plants. With this in mind we are pleased to 
be able to offer to the Truck Farmer this inexpensive power duster 
developed by the Messinger Co. 
This is a light, well-constructed power 
Duster which is easily operated by a man 
walking to steer it. It is equipped with 
a gas engine which propels the duster 
and operates the duster blower unit. 
The standard dust hopper or self mix¬ 
ing dust hopper has a capacity of about 
30 pounds, from which the dust is fed 
through the feed gauge into the mixing 
chamber by a Force Feed Spider com¬ 
posed of alternated right and left spirals. The Feed Gauge is made of 
heavy brass with a “V” opening which is easily and quickly regulated 
by a lever riding over a notched quadrant. In the Mixing Chamber the 
dust is mixed with air by two beaters, 
air-floating the dust which is then drawn 
into the fan which blows it out through 
the distributor, tubes and nozzles in a 
highly air-floated condition forming a 
dust cloud around the plants, penetrating 
into the pores, hairs on the leaves and 
stalks and into the small recesses where 
the insects hide, breed and feed. It 
reaches these hidden insects like smoke 
and penetrates into spaces where water 
cannot reach.

The nozzles bar permits 
SEP-4-30 
many arrangements for the fan-shaped 
nozzles in height and angle. Thus it is 
possible to dust all types of small crops, 
using one or two nozzles to the row. 
The Duster and Engine are mounted 
on a sturdy frame, carried on a Irk axle 
6% feet long with standard 36" wheels 
(also furnished with 48" wheels), with 
ZV 2 inch tires. The wheels are of a 
ratchet type permitting easy steering 
and are movable on the axle allowing a 
wheel gauge for any width rows.
