6. A rod called the weed hook is provided to collect the 

 tops of high vegetation. 



7. Practically all wheel plows are now provided with 

 inclosed wheel boxes, which exclude all dirt and carry a 

 large supply of grease. The inclosed wheel box has a 

 collar which excludes the dirt at the axle end of the wheel 

 box, and has the other end entirely inclosed with a cap. 

 The grease is usually stored in the cap, which is made 

 detachable from the hub. 



8. Wheel plows are now generally provided with a 

 foot lift, by which the plow is lifted out and forced into 

 the ground.

10. The various parts of the sulky plow are usually 

 attached to the frame, and this is an important part in 

 the construction of the plow. Not all sulky plows, how-

 construction. The two-wheel plow is not used exten- 

 sively at the present time because it does not carry the 

 side pressure of the plow well and does not turn a good 

 square corner. One type of construction is that of a 

 frame w_itlx-wh^^ls_attached by means of brackets, making 

 a^carriage. To this carriage the plow proper is attached 

 by bails. The hitch to frame plows may be to either the 

 frame or to the plow beam. The former is known as a 

 frame hitch and the latter as a beam hitch. There are 

 good plows upon the market with a frame hitch, but the 

 beam hitch plow seems to be preferred. 



A cheaper type of plow than the frame plow is the
