The Hallock “O. K. Elevator” Digger. 
We give some details of our construction which combines every essential feature in all other elevator diggers, and these are 
supplemented by other vital features. 
1st. Our elevator bottom is a huge fork hinged at lower end and agitated its whole length, and will run clean in the most 
adverse conditions. 
2nd. This huge fork is supplemented by a rear fork which has more efficiency for separating than some elevators have in 
their whole mechanism. It is supported centrally, and agitated by a crank axle at its head, which gives a combined horizontal and 
vertical motion. The speed and vertical motion are adjustable, and being supported centrally it takes very little power to run it. 
3rd. The single wheel truck is ten inches wide and runs the vines and weeds down from the machine, favorable for entering 
the elevator, and it sustains more uniform depth than a two wheel truck, where fields are washed. We, however, make a two- 
wheel truck for use in square planting. When ordering diggers it should be specified which truck is wanted. If no preference is 
given we will send the single-wheel truck. 
4th. By our laterally rigid pole mechanism, you have the maximum of convenience for operating the machine, and the 
truck and shovel are both raised simultaneously by an independent lever, so the depth gauge lever need not be changed to turn at 
end of row. (This is a feature found on no other digger.) 
5th. Team is hitched close to shovel, and draft connection with machine is well forward which is favorable for light draft and 
least strain on machine when striking rocks. The “0. K.” Diggers are supplied with tongue and neck yoke only, no eveners. 
Eveners can be supplied when ordered extra.
