FARMERS' BULLETIN 933. 



average grove conditions in Florida that weighs more than 1,800 

 pounds. To be of the greatest value a machine should weigh not more 

 than 1,400 to 1,600 pounds. It is also desirable in many instances to 

 have a cross reach for the truck which will permit it to be turned 

 in a very small circle. The tires should be 6 inches in width and the 

 diameter of the wheels should be as great as is practicable. In many 



instances, however, 

 where the branches 

 of the trees are near 

 the ground, it is de- 

 sirable to have the 

 machine as low as 

 possible to prevent 

 pulling off fruit and 

 the leaves. Some 

 machines are built 

 unnecessarily high 

 and when used in 

 such a grove cause 

 much damage. 



Since the wheels 

 with which the 

 spraying machines 

 are fitted are ex- 

 tremely heavy, often 

 comprising half of 

 the weight of the 

 empty machine, it is 

 extremely desirable 

 that lighter wheels 

 be constructed for 

 this special purpose. 

 A machine for 

 Florida conditions 

 should be fitted with 

 a tank located in 

 front of the engine 

 and pump (not as 

 in fig. 14). This gives the operator an opportunity to attend the 

 engine from the rear of the outfit without interfering with the team, 

 and also eliminates the danger which usually follows when an engine 

 is placed immediately in the rear of a pair of mules. The tank should 

 contain an opening large enough to permit a man to go inside to clean 

 it out. The opening should be fitted with a removable fine-mesh wire 

 strainer. The tank and the cab over the engine and pump should be 

 flush with each other (see fig. 13), in order to prevent the catching 

 of branches, carrying off of fruit, and other injury to the trees. 



FIG. 1). It is impossible to get good results without exten- 

 sion rods and this type of spraying is useless. The 

 grower failing to get results condemns all spraying as 

 useless when the fault lies in the lack of the proper 

 equipment.
