An essential attachment component – a complete, reinforced mechanical quick hitch from the COBRA series. Designed for the rear dipper arm of KOMATSU WB93 and WB97 backhoe loaders (also fits TEREX / FERMEC 760-970). It allows for instant and safe changing of attachments (like buckets, rippers). The COBRA model, with internal reinforcements and a special shell design, resists twisting and is ideal for heavy-duty work. The quick hitch is brand new, complete, and ready for installation (does not include mounting pins for the arm).

The list above is for reference. You must verify your dipper arm dimensions: 45 mm pin diameter, 160 mm arm width, and 295 mm pin centers.
Never operate with a suspended attachment unless you are 100% certain the quick hitch mechanism is correctly and fully locked. Always perform test curls and movements close to the ground after changing an attachment. An unexpectedly detached bucket can cause fatal injury.
A mechanical quick hitch radically shortens the time needed to change attachments, increasing machine efficiency. Its failure or wear mainly manifests as problems with securely attaching buckets.

The COBRA model features internal reinforcements and a special shell design. It is designed for heavier work and performs better in sticky materials like clay, which could clog standard hitches.
2. How does this mechanical quick hitch work?A mechanical quick hitch requires manual operator intervention. After hooking the front pin of the bucket, the operator uses a special key (bar) to turn a screw mechanism, which extends and locks the second (rear) bucket pin. It is a simple, reliable, and economical solution.
3. Will this fit an older Komatsu with 40mm pins?No. This model (QHM-KOM-45) is specifically for machines with 45 mm pins. The version for 40 mm pins is a different part, available by special order. This item will not fit.
