If you go to http://www.ingersolltractors.com and then click on the "illustrated parts list" link near the top of the page, you can scroll down the list of PDF's to the tractors and then click on the one for the 442's. When it opens for you, scroll down until you get to pages 76/77 of the actual catalogue or page 40 of the PDF.
There you will find an illustration of the sleeve hitches for both the 200 and the 400 series tractors. The long arm which is item 2, is the one that connects the sleeve hitch to item 8, which is the bracket that bolts onto the bellcrank of your tractor. The bellcrank is the item that moves back and forth on the right side of your tractor (and the left too) that lifts up your mower deck whenever you pull the lever on the right side of the steering wheel.
