International Harvester Cultivator

The Cultivator is a one-row cultivator designed for use the Farmall International Harvester A Super-A, 100, 130 and 140. Two versions were built one for Tractors equipped with Hydraulic Touch-Control and a manual lever operated version for tractors without hydraulics. Cotton, corn, potatoes, and other crops may be cultivated when planted in rows spaced from 40" to 68" apart. The operator has a clear unobstructed view of the row due to the offset of the tractor seat. Small young crops are followed accurately and where conditions permit, cultivating speeds up to 4-1/2 miles per hour can be maintained.

All adjustments for depth and lifting at the ends of the field are accomplished from the driver's seat. The hydraulic version has 2 levers. One lever serves to control the front section and the other the rear. Instant and positive depth control enables the driver to cultivate hard and soft spots in the field to a uniform depth. The manual version has 2 levers for the front. The left one lowers the left side and is latched to the right one. The right one lowers both front plows. Another lever sets to the right of the driver and lowers the back. This makes it hard to mount the tractor and some farmers only use the front set so they don't have to keep the back set on the tractor.

Tractor without Fast-Hitch: The universal mounting frame and either the rear rigid rockshaft or the rear split rockshaft are required. These units are used in various combinations with all direct-connected implements for these Tractors. The universal mounting frame is used with front-mounted planters and cultivators; the rear rigid rockshaft is used with cultivators, bedders, cane tools and plows (except the No. 189 Two-Way plow); the rear split rockshaft is used with cultivators, bedders, cane tools and plows (including the No. 189 Two-Way Plow).

Tractor with a Fast-Hitch
The universal mounting frame and the Fast-Hitch are required. These units are used in various combinations with all direct-connected implements for these Tractors. The universal mounting frame is used with front-mounted planters and cultivators; the Fast-Hitch is used with cultivators, bedders, cane tools, and plows.
The universal mounting frame consists of two parallel-action gang assemblies mounted one on each side at the front of the tractor. Each assembly includes a frame, push pipe with pressure spring, parallel-acting gangs, and a tool bar attaching bracket. The attaching bracket is provided with a keyhole slot to facilitate attaching and detaching the ground working tools without disturbing their adjustments .

The Fast-Hitch is used with the cultivator rear section. By connecting the pressure rods to the rockshaft arms, raising, lowering, and control of depth is maintained. The hitch pull bar and stabilizing links may either remain in place or be removed, as desired. Remove the pull bar and stabilizing links to give clearance over crops having high foliage.

Tractor without Fast-Hitch: The rear rigid rock-shaft attaches to the tractor rear fenders and consists of a rockshaft with bearings and an adjustable lift link. The rear split rock-shaft, designed for use with the No. 189 Two-Way Plow, can be used equally well in place of the rigid rockshaft. If you intend to use the Two-Way Plow, it is recommended that the split rockshaft be obtained to avoid purchasing both rockshafts.

The cultivator gangs are easily and quickly attached or detached without disturbing any of the set adjustments when the tractor is to be used for some other purpose. This assures the cultivator working at the same depth and in the same relation to the row when it is reattached as it did when last used.

The ground working tools have 1-1/4" round standards. The standard clamps are the single wedge-bolt type which are easily and quickly adjusted. The clamp is designed so that a single wedge bolt secures the vertical adjustment of the standard and, at the same time the position of the clamp along the tool bar. Tool bar extensions are provided for the sweep running next to the row and these have ample adjustment so the sweep may be set closer to or farther from the row, as desired.

The cultivator is available with tool equipment having either No. 16 or No. 19 Style Spring Trips or with Spring Teeth. Friction trips are also available when ordered in lieu of the spring trips. A pair of No. 122 Cultivator Shields are included with tool equipment having spring trip or friction trip standards. A pair of No. 91 Cultivator Shields are included with spring tooth tool equipment.

A great variety of tool equipments and attachments are available to meet the requirements imposed by the various crop and soil conditions. These are: Barring off disk attachment - may also be used for hilling up when desired. Disk hillers - for throwing dirt to the row or for barring off. Spring teeth - for use in stony or rooty soils.

Rotary weeder - for high speed cultivation of small young plants.

Tent type shields - for high speed cultivation of young crops.

Fertilizer unit - for placing fertilizer beside the crop row.

Peanut digger attachment - used to cut the ground under the vines and lift them out so they can be windrowed or bunched.

Weeder-mulcher - to break up crusts and keep the surface free of weeds and well mulched.

Friction Trip Standards - used in place of spring trip standards in fields which are free of stones and roots.

The Fertilizer Stream Divider Attachment is designed to divert the flow of fertilizer from one hopper into two delivery tubes to permit fertilizing on both sides of the row or to fertilize two rows for each hopper used. The divider case has an adjustable valve which may be set to divide the flow of fertilizer equally into the two tubes, or all or any portion of the fertilizer may be diverted into one tube as desired.

The No. 101 Fertilizer Unit, used for side dressing. It consists mainly of the countershaft assembly and delivery assembly. The countershaft assembly includes the parts necessary to drive the seed hoppers used with the No. 179 and No. 180 planters (direct connected). A mounting plate on the countershaft provides a ready means of attaching the seed delivery parts. This results in a saving to the owner operating both planter and fertilizer attachment.

The delivery assembly includes the hopper and mounting bracket which may be used for fertilizing beside the seed when using one of the planters mentioned previously. A few extra parts are required when this is done.

Two styles of hoppers are available. The style wanted may be ordered either with the unit or separately. Either style is driven by the same support and drive parts. These hoppers are the star feed type with a fingered wheel revolving in the hopper bottom to carry the fertilizer under an adjustable gate to the discharge opening. Sliding gate type hopper. This hopper is made of heavy galvanized sheet metal with a capacity of approximately 65 pounds of average commercial fertilizer.

Rotary gate type hopper: This hopper has a capacity of 115 pounds of average commercial fertilizer. The hopper may be either the steel hopper or the fiber glass hopper. The fiber glass hopper is non-corrosive and translucent, thus the level of fertilizer is constantly visible. The quantity of fertilizer sown is regulated by adjusting the gate opening with the lever outside the hopper, by changing feed wheels inside the hopper, or by changing the sprocket on the feed shaft.

The range of distribution may be from 25 to 1,740 pounds per acre. The gate opening lever will permit a range of 25 to 510 pounds per acre when the regular feed wheel and the slow speed sprocket are used. The range is from 50 to 890 pounds per acre when the fast speed sprocket and the regular feed wheel are use'd. These figures are approximate and are based on average free-running commercial fertilizer and 40" row spacing.

A extra hopper attachment can be mounted on the left side of the tractor. This attachment is designed to approximately double the amount of fertilizer put down by the regular unit
