THE IMPROVED “PLANET JR.” WHITE 
POTATO DIGGER 
The “Planet Jr.” White Potato Digger has been greatly- 
improved recently. Instead of a digging head of tines it 
now consists of successive shares, which cut the furrow 
turned on edge by the front share and moldboard into 
horizontal slices, throwing the vines and weeds to one side 
and pushing the potatoes to the surface. 
Doubtless you would like us to say how they compare with 
the various four-horse diggers on the market. To answer 
this, the “Planet Jr.” White Potato Digger is equal to any 
for digging early, when the vines are green, the potatoes fast 
to them and the ground clean A little later on, when the 
vines are dead and the ground fairly free from weeds, the four- 
horse diggers do better work in some cases, the crop being 
picked up more easily after them. At a later stage, when the 
field grows very grassy and weedy, the four-horse tools are almost useless, while the “Planet Jr.” even then does its 
work fairly well. If compelled to use but one digger the season through, the “Planet Jr.” is the best. It costs but 
one-fourth or one-fifth as much, takes less than half the power to draw it; DOES NOT SKIN THE POTATOES, 
digs faster and costs about one-twentieth as much for repairs, and it will last almost a lifetime, with a few new shares 
and landsides. Packed weight, 143 pounds. Price. $ 42.50 
No. 300 “HOOVER” POTATO DIGGER WITH AGITATING 
REAR RACK AND VINE SEPARATOR 
To meet the various conditions under which potatoes are grown, it was necessary to build several styles and sizes 
of machines. In making the changes and improvements necessary to the universal use of the “Hoover” they were 
designed so that two general or main frames would be the basis to which could be added the different attachments 
for the various styles and sizes 
that are necessary for the suc¬ 
cessful harvesting of the crop. 
The frames are 6 and 7 feet long 
and of two widths, 20 and 22- 
inch. The following general de¬ 
scription of the construction of 
the “Hoover” should convince 
you that nothing but the best 
of material and workmanship is 
used in their construction, 
which in connection with the 
inventive genius, which is con¬ 
stantly used for their better¬ 
ment, puts them in a class by 
themselves, and about five 
years ahead of all imitations.

SHAKER 
POTATO DIGGER 
Steel beam. Natural temper steel blades. 
Provided with weed fender and gauge wheel. 
The Shaker Digger has a perfectly flat blade and 
will not cut the potatoes. The rod grating is 
hinged at the front and is given an up-and-down 
shaking motion by the sprocket wheel at the rear. 
This shakes the dirt off from the tubers and leaves 
them clean and whole on top of the ground. The 
weed fender is intended to clear away weeds and 
vines, preparing the way for the blade. The 
Digger is shipped with gauge wheel and fender, 
unless ordered without.
