Wy invention relates to that class of harrows 

 or cultivatoi-s having gangs of disks, prefer- 

 ably concavo-convex disks, adjustably con-

 construction, combination, and armngemcnt 

 of Ihe parts, as will be herew ilh set forlh and 

 specifically claimed. 



1. In awheel or disk harrow, the combina- 

 tion, wilh the main frame and the wheel gangs 

 independently pivoted thereto, of the pole or 

 tongue with coivuccting mechanism, whereby 

 the sliding of said pole or tongue backward or 

 forward carries the wheel-gangs and shifts 

 their relative position from a straight-line to 

 any angle desired, or vice vei-sa. 



2. Iu a wheel or disk harrow, the combina- 

 tion, with thomainframcand the wheel-gangs 

 independently pivoted thereto, of the back- 

 wardly and forwardly sliding pole or tongue 

 extending back between the adjacent ends of 

 the gaiig-beains, and united thereto by adjust- 

 able connections, whereby the sliding of the 

 pole in one direction will cuiiso the wheel- 

 gangs to be .shifted from a straight line to a 

 forward angle, or from a rearward angle to a 

 straight line, and vice versa, as desired. 



3. In a wheel or disk harrow having a main 

 frame with independently - pivoted wheel 

 gangs, the tongue or pole working through 

 lixed guides secured to the main frame and 

 adjustably connected to the adjacent ends o( 

 the gang-beams, and provided with a series ol 

 perforations, in combination with a slotted 

 plate or coupling secured to the main frame, 

 a superimposed jierforated plate, and a re- 

 niovabloconpling pin atiapted to pass through 



said perforations andtheslot in the coupling- 

 plate, whereby Ihe forward adjtuitment or play 

 of the polo can be regulated at will to .shift 

 the wheel-gangs by the driver from his seat on 

 the machinr, as set forth. 



I. In a wheel or disk harrow havinga slid- 

 ing jiole or tongue for adjusting the wheel- 

 gangs simnllnneously from a sLraigliL to an 

 angling posilitm, or vice versa, the combina- 

 lion, with said pole, of ast^j) for limiting the 

 backward play of saiil pole, substantially as 

 il escribed.

 or longne for arljnsting the wheel-gangsimni

 teiuRng from Ihe forward end of the beam H

I tion, with the lolaling disk or disks, of a 



scrapi-r-blade for each disk pivoted at a point 



between the axis and perii>hery of said disk. 



whereby said blade can adjust itself lo the. 



surface of the disk at all points of its scraping 



surface from one cnil to the other. 



S. In a wheel or disk liarrow, the'condiina

 of a scries of pivoted rocking arms carrying 

 self-adjusting scraper.s, which said arms are 

 connected to and operated by a bar or rod, so 

 a.s to be vibrated simullaueonsly tliroughthe 

 medium of a lever or ecpiivalcnt device.
