THE PERGHERON REVIEW 
Figure 6. The Six-Horse Team Hitclied to Disc Harrow 
To secure a 6-horse equalizer, Figure 4, the two rear 
units of tlie 10-horse hitch are removed. This hitch will 
be especially useful on a 2-bottom 28 inch plow for fall 
novk when it is desired to plow deeper than usual or 
when tlie ground becomes hard. It should be especially 
useful in plowing for the seeding of winter wheat. 
Tlie 4-horse equalizer, Figure 5, is secured by remov- 
ing the three rear units of the 10-horse hitch. It is 
merely a fixed pulley with chain and draw rod. This 
hitch should be used whenever 4 horses are worked on a 
gang plow. It can also be used to advantage on the 
sulky plow whenever the conditions are such as to make 
the draft relatively heavy. 
Disc-Harrow Equalizers 
The disc-harrow does not present the perplexing 
hitch problems met in connection with the plow. By 
using the tongue truck, four horses can be worked 
abreast with entire satisfaction. When it is desirable to 
use more than this number of animals some difficulty is 
experienced because the outside horses swing into the 
implement on the turns. This trouble can be overcome 
by using the tandem hitch. When 6 horses are worked

on the disc-harrow, a (3 and 3) combination as illus- 
trated in Figure 6 can be used. The draft between the 
two tandems is equalized by means of a block with two 
pulleys around which a chain passes ; Figure 7. The 
rear team is attached to one end of this chain and a draw 
rod 11 feet long to the other end. In order to allow 40 
inches of space for each horse the outside of the pulleys 
should be 20 inches apart. It is recommended that the 
pulleys be at least 4 inches in diameter, larger than those 
shown in Figure 7. Four lines are used for driving this 
team. If it is desired to use 8 horses on a disc-harrow 
a tandem arrangement (4 and 4) can be secured by 
using two 4-horse equalizers and balancing the pull be- 
tween the wheel and lead teams by means of a single 
pulley, chain and a draw rod.
