KitchenAid's historical bowl-lift mixers were built under the Hobart Manufacturing Company and early KitchenAid branding. The K5SS (Hobart Era) is one of the most sought-after vintage mixers — built with all-metal construction and a gear train designed to last decades. The K5A and K4A are Hobart-era 5-quart and 4-quart bowl-lift models. The KSM5 and KSM50 bridge the Hobart and modern KitchenAid eras. The K655 Epicurean is a premium 6.5-quart bowl-lift model from the late KitchenAid lineup.

⚠️ Pro tip: Hobart-era KitchenAid bowl-lift mixers (K5SS, K5A, K4A) used all-metal gear trains that rarely fail. The most common issue on these machines is dried or degraded grease — a full grease service often completely restores a machine that hasn't run in years. Don't scrap a Hobart-era mixer over a grease issue.

✓ Model Overview & Parts Notes

K5SS (Hobart Era): The gold standard of vintage KitchenAid bowl-lift mixers. All-metal construction, 5-quart bowl, extremely durable gear train. Carbon brushes and grease are the most common repairs. Some parts cross-reference with the KSM5.

K5A: Hobart-era 5-quart bowl-lift. Shares many components with the K5SS. Contact us for cross-reference guidance.

K4A: Hobart-era 4-quart bowl-lift. Smaller platform than the K5A/K5SS. Parts are scarcer — contact us for sourcing assistance.

KSM5: Transitional model bridging Hobart and modern KitchenAid. Some components cross-reference with both K5SS and early KP26M1X parts. Good parts availability.

KSM50: Early KitchenAid-branded bowl-lift. Parts cross-reference with KSM5 and early Pro Series models. Contact us for compatibility guidance.

✓ Common Repairs on Historical Bowl-Lift Models

Dried or degraded grease: Most common issue — full grease service restores most machines.

Carbon brush wear: Causes intermittent shutoff or failure to start — brushes are often still sourceable for K5SS and KSM5.

Bowl lift cam wear: Cam and lift arm wear on high-mileage machines — inspect before assuming motor failure.

Speed control issues: Governor-style speed controls on older models can be cleaned and adjusted.

✓ Buying Options

OEM / NOS Parts: New Old Stock (NOS) OEM parts are available for some models through specialty suppliers. Contact us for sourcing assistance.

XPart Aftermarket: Aftermarket parts are available where cross-reference with current Pro Series components applies. XPart aftermarket replacement parts are not affiliated with, sponsored by, or endorsed by KitchenAid or any OEM manufacturer.

✓ Installation Tips

Always unplug before any repair. Document your disassembly with photos — vintage bowl-lift machines have fewer online repair guides than modern models. Use food-grade grease rated for high-temperature applications. On Hobart-era machines, the bowl lift cam is accessible from the base — inspect it before pulling the head apart.
