THE IMPERIAL "U" BAR LEVER HARROW 



The Imperial "U" Bar Lever Spike Tooth Harrow is 

 made in a strictly first-class manner throughout, In 

 construction, this Harrow has many advantages over 

 those of other manufacturers. The frame of the Har- 

 row is channel steel, of good weight and strength. 



The "U" Bars pass 

 through the main frame 

 of the Harrow, and are 

 held in position by a 

 malleable clamp. The 

 construction gives great 

 strength to the Harrow 

 and at the same time al- 

 lows flexibility. Each 

 section is fitted with 

 four steel runners, one 



attached to each corner, for transportation. These runners, when the Harrow is at work, are on top of the 

 frame and do not obstruct. By throwing the lever forward the runners are thrown down in a position which 

 carries the entire Harrow off the ground.

Instead of being guided by a tongue, the Harrow is con- 

 trolled by a two-wheeled truck attached to the front end of 

 the frame. The Wheels are pivoted under the frame and 

 allow a square turn to be made. The truck exercises a posi- 

 tive guidance and control over the Harrow, which follows it 

 just as the rear wheels of a wagon follow the front wheels. 

 No one will deny that the tongue as used on the ordinary 

 Disc Harrow is more troublesome and less under control 

 than the tongue on other implements. It is jerked violently 



from side to side by the mo- 

 tion of the Harrow, frets and 

 worries the team, and is espe- 

 cially annoying in turning cor- 

 ners. The Fore Truck does 

 away with all this. The team 

 is easily managed and works 

 quietly and evenly without be- 

 ing subjected to the pounding 

 of tongue and neck yoke. 

 There is no neck weight and 

 no side draft. The Harrow 

 simply follows the truck. 



The position of the Frame 

 on the Fore Truck is adjust- 

 able. This is important be- 

 cause to secure a uniform 

 depth of cut the frame should 

 be level with the surface to 

 the ground. If the front end 

 of the frame is too high the 

 inside disc blades will cut too ' 

 deep; if too low, the outside discs will cut too deep. When the frame is level all the blades cut alike, and uni- 

 form cultivation is secured. The Hitch also is adjustable, and may be made considerably lower than on a 

 tongue Harrow, the lowest hitch hole being only 14 inches from the ground. The line of draft is consequently 

 lower and the pull of the team therefore more effective. These adjustments of frame and hitch enable the 

 operator to get the best and most effective work out of his machine with the least exertion on the part of his 

 team.
