Fic. 15.—Harvesting sugar beets with a crotch lifter that is operated by a crew of 
one man and four horses. 
There are two general types of implement used in doing this work, 
viz, the crotch lifter and the side lifter. (See fig. 15.) The crotch 
lifter has double prongs which run on both sides of the row, while 
the side lifter has single points on the ends of long, thin, cutting 
blades, the most common size being the one-row implement with but 
one point. This is called a “side lifter” because the point runs at 
the side of the row. The crotch type lifts only one row, while side 
lifters are made to lift from one to four rows at a time. Side lifters 
are universally used when tractor power is employed. (See fig. 16.) 
The size of the lifter used depends on the horsepower of the tractor. 
Both side and crotch lifters were used in the Los Angeles district. 
On Salinas farms crotch lifters were used exclusively, while on 
farms in the Oxnard district the side lifter was the universal type.
