THE MODERN, HIGH-CAPACITY, HEAVY-DUTY 
HOPPER GRINDER 
LETZ No. 110 
Built for a lifetime of better grinding service. 
Built to uniformly granulate feeds. To make ex¬ 
cellent cracked corn, wheat or barley. To pul¬ 
verize small grains! To grind feeds all coarse, all 
medium, or all fine. To grind snapped corn with 
all the shuck! To grind sorghum heads with stems 
up to 4" long. To grind soft corn, wet enough to 
wring water from! 
10" plates are regular, for 10-20 tractor. By 
using 8" plates it is operated by small engines or 
motors, 5 to 7pj h. p. 
Because it cuts the feed, because it forcefeeds, 
it has two to three times the capacity of the or¬ 
dinary 10" grinder. It keeps one man busy filling 
the hopper. 
Price..$73.00 
LETZ No. 220 
Is the larger size, heavy-duty Letz with 10 Lj" 
“zig-zag” shearing plates, for 15-27 tractors or 
simliar power. 
Like its No. 110 companion, it grinds ear corn, 
snapped corn with shuck, maize heads and small 
grain, better, faster and cheaper! 
Improved design produces a sturdy and com¬ 
pact grinder of surpassing ability. No. 220 Letz 
has 1-11/16" alloy-steel, main shaft with 6" wide, 
overhanging main bearing, and the amazing Letz 
thrust bearing, all for heavy duty operation by any 
size power.

operating costs—new dependability—new value.

No. 222 LETZ WITH EXHAUST FAN 
AND SACKING TOWER EQUIPMENT 
Letz heavy-duty grind¬ 
ers are considered incom¬ 
plete without the ball¬ 
bearing exhaust fan. The 
fan aerates, cools and de¬ 
livers the ground feed. It 
mixes feeds, saves hand¬ 
ling and rehandling work, 
stores the ground feed 
away more safely. 
With exhaust fan you 
can dispose of the ground 
feed as you wish. You 
can add a sacking tower, 
swinging wagon box tow¬ 
er, or build up a feed 
distribution installation of your own, at low cost, by adding 
pipe, elbows, valves and branch lines to make the work of the 
fan still more valuable. 
Blow your ground feed into overhead storage bins, into 
self-feeders, or to 3, 4, 5 or more storage locations within 100 
feet radius from the grinder. 
This is the way to meet the feed handling job, to cut costs 
and to add convenience! Why not make this installation 
now!
