The HITCH is a very important part of any moldboard plow (draw or pull-type plows)! It is often a forgotten and neglected part of older plows and can cause a lot of frustration and headaches if not in good working order. Drawn type plow hitches normally serve two important functions:
First they provide a means of adjustment for the proper width of cut for the front plow bottom.
Second they often provide the means for the plow to disconnect from the tractor when an obstruction is encountered as to prevent damage to the plow. Some hitches only cushion the shock to the plow when something solid is hit with the bottom (such as a rock or large tree root).
It is fairly common for older plow hitches to be missing parts and pieces and to have incorrect hitches. Also some plows have hitches today with which they weren't originally equipped. Often these incorrect hitches are from other brand (not Deere) plows. Knowing what types of hitches were offered on your John Deere plow is essential to being able to procure correct parts.
We have some new parts for JD plow hitches in addition to a good supply of used parts.
When using a semi-integral John Deere F135 or F145 series plows behind a tractor which has the draft sensing through the center link, a special hitch Mast Attachment was offered by JD for this application. Long since obsolete and difficult to find in used condition we now offer this part as a new repdroduction kit. Includes everything you need to upgrade your plow for use with your JD 2010, 630, 620, 720, 730, and other model (non-JD) tractors in this situation. * This attachment is not compatible with the optional hydraulic landing type hitch (moves hitch crossbar laterally by means of a 8" cylinder). Includes 1 AA11477 mast, 2 A12689 plates, 1 A12876 clip, and 1 17047 spring. Price is $175 for the kit.
The cushion release type plow hitch is most common on John deere plows made from the 1920's until the mid-1950's (after which point most plows made allowed each bottom to trip individually rather than the hitch). The release hitch came in several versions, but most commonly was the latch type spring cushion release hitch was used on two bottom plows. (see above photo for example).
Optional on many models of two bottom plows and standard equipment on larger 3, 4, and 5 bottom plows (such as 55, 66, and 77 models) was the spring cushion revolving release type hitch. The 'cog' at the end would spin when the springs compressed enough to release and allow the clevis on the tractor drawbar to go free.
The hitch trigger is a very important part of the revolving cushion spring release hitch. This part keeps the clevis engaged against the cog at the end. Without it, your plowing experience will be filled with frustration as the hitch may become disengaged when turning on the headlands. The new trigger replaces original part numbers: G672A, 32848A, D938A, G656A, and G671A. This type of hitch was used on some of the following plows: 51, 52, 55, 56, 57, 66, 77, F610, F640, F670 among other plows. Made from ductile iron, it will provide years of trouble free service. Price is $25
To compliment the hitch trigger (shown above), here is a new reproduction trigger spring. It's purpose is to keep the trigger in the down position so that the hitch will not accidentially come undone when traveling over rough terrain. This was a standard item on rotary spring cushion hitches used on model 51/ 52, 4B, 4C, 4D, 22, 44, 44H, and No. 57 plows. The aforementioned models all had one thing in common: they transported on only 2 wheels when out of the ground. In other words the hitch of the plow will give positive lift when in transport position and thus the spring on the trigger is absolutely necessary. Unfortunately, this part hasn't been avaialble new from JD for many years. Now it's back and here for you. Replaces OEM part 27167A $20 each
See how the trigger and spring go together (photo at left). To release the trigger simply pull up on the trigger against the spring to unhook. The spring attaches to a bolt in the hitch.
Often missing is the latch for the spring cushion release hitch. This hitch was used on numerous JD plows including: 51, 52, 4B, 4C, 4D, 5C, 6C, 730 LISTER, and perhaps other models such as 55 and 44. Replaces OEM part 19015A Add a new release latch to your JD plow for only$25.
See the part diagram view below to understand the hitch and how it works. Either a plow clevis or loop type drawbar would be the proper way to attach this type of plow hitch to your tractor.
