1 52 SCIENCE OF SUCCESSFUL THRESHING 



machine. It is not necessary to have the front axle level, 

 as the bolster- jacks will accommodate themselves to it. 



Place a block in front of the right-hand rear wheel to 

 prevent the machine from being drawn forward by the belt. 

 This block should be carried with the machine, so as to be 

 handy when needed. 



When pulling the machine out of holes with a team, 

 starting it on soft ground or on a hill, face or head the team 

 around to one side, and it will move the load with about 

 half the effort necessary to start straight ahead. In cramp- 

 ing the front axle, but one of the hind wheels starts at a 

 time. 



Setting with Reference to the Wind. The thresher- 

 man cannot always choose the direction in which to set the 

 machine, but when he can, he should select a position in 

 which the wind will be blowing in the same general direc- 

 tion as that in which the straw is moving, and preferably 

 a little "quartering," as this keeps the men out of the dust 

 more than when set straight with the wind. This posi- 

 tion insures greater safety from fire in case wood or straw 

 is used as fuel. 



In Case of Fire, the quickest way to move the machine 

 away from the stacks is to pull it out by the belt. Take 

 the blocks away from the wheels, place a man at the end 

 of the pole to steer, and back the engine slowly. If the 

 machine be in holes or soft ground, put men at the wheels 

 to assist in starting.
