User manual MTD OEM-290101 INSTALLATION INSTRUCTIONS

[. . . ] This is a standard tow hitch design which can be used for attachments including the TROYBILT Sweep Cultivator. You may also use it with other attachments you already own, such as a lawn roller, four-wheel shredder, or a drag-mat. [. . . ] Refer to Photo 6 below showing the Tine Attachment in place on the Tine Cradle. If you do not have a Tine Cradle, you may instead prop up the Tine Attachment housing with a block of wood to keep the transmission housing level, thereby preventing gear oil from leaking out of the dipstick hole. CAUTION • Always handle the edges of the tiller hood carefully. • When an attachment is removed from the Power Unit, always place a wood block or other sturdy support beneath the coupling to prevent the attachment from falling forward. Figure 2: Insert both dust caps. Step 3: Install the Tow Hitch A. Align the hole in the right-hand corner of the Tow Hitch with the alignment pin at the PTO access hole. Note that the washers on the swing-bolts should be next to the bolt heads. Tighten the swing-bolts by alternating between the two bolts to achieve even tightness. Tighten the bolts securely, using a 3/4" wrench at least 11" long (this length provides sufficient leverage to tighten securely), until the concave washers on both bolts are flat. Or, if you have a torque wrench, tighten each bolt to 70-80 ft/lbs. Step 2: Use of Dust Caps A. Insert the smaller, 1-1/2 " dust cap into the PTO access hole, as shown in Figure 2, whenever the Power Unit is detached from the Tine Attachment. With the dust cap in place, the access hole is protected from the entry of dust, dirt and moisture. The dust cap may remain in place for the operation of non-powered attachments such as the Tow Hitch. It must, however, be removed before attaching the Tine Attachment or other powered attachments. [. . . ] Attachments that have only a single-tongue connection should not be used because they allow the Power Unit to tip forward or backward excessively and make the machine difficult to control. Some lawn rollers, harrows, and other drag-type attachments may come very close to you as you make sharp turns. [. . . ]
