The Kubota 393 Master Key – Keeping the Classics Cranking

Got an older Kubota that’s been the backbone of your property for decades? If your ignition key has 393 stamped on the blade, this is the exact replacement you need. These vintage tractors are built to last a lifetime, but the keys have a habit of going walkabout in the paddock after 30 years of service.

Why You Need This (Aside from Keeping a Legend Alive)

• Vintage Precision: Specifically cut for the older Kubota ignition barrels (15272 series) that require a narrower blade profile.
• Solid Metal Design: A no-nonsense, all-metal key (or slim polymer head) that fits perfectly into the dash of classic B and L series models.
• The Reliable Spare: Don't risk snapping an old, worn key. Get a fresh 393 cut to factory specs.

Compatible Equipment

The 393 key is the primary fit for older Kubota models, typically manufactured between the late 70s and late 90s, including:

• L-Series (Vintage): L175, L185, L225, L235, L245, L275, L285, L295, L305, L345, L355.
• B-Series (Vintage): B5100, B6100, B7100 (The legendary grey market and Aussie models).
• KH Series Excavators: Fits many older KH-series mini diggers (e.g., KH-1, KH-35, KH-41).
• Industrial: Various older Kubota diesel generators and power units.

Technical Specs

• Part Number: 15272-63700 / 15272-63702
• Stamp Code: 393
• Design: Slim, double-sided all-metal blade.
• Application: Vintage Rotary Ignition Switches.

Pro Tip: If your Kubota has a digital dash, you likely need the 459A. If it's got analogue gauges and some honest "character" (rust), the 393 is usually your winner.
