Which machines will this ignition switch fit?

The Solarhome AT195301 covers numerous John Deere types — from compact tractors and loaders to larger harvesters and graders — plus specific Hitachi crawler and loader models. Fitment targets the OEM part references AR47458 and AR58126, so check your machine’s parts list or existing switch number for confirmation.

• Fits John Deere models: 250, 2350, 2355, 2440, 2520, 2550, 2555, and many more
• Compatible with backhoe loaders: 210C/310C/315C series and related variants
• Also fits dozer, grader and harvester model lines listed in product specs
• Interchanges with Hitachi crawler/loader models such as DX75L-2 and LX150 series

How straightforward is installation and what do I need?

Installation is typically straightforward for technicians or owners comfortable with mechanical replacements: the unit installs in the existing dash/key assembly location and uses the vehicle’s original wiring harness. No special programming is required because this is a mechanical keyed ignition, not an immobilizer module.

• Remove old switch, match harness connector and mounting dimensions
• Slide new switch into dash aperture and secure with original fasteners
• Verify key positions (off, on, start) and electrical continuity before final assembly
• Keep the spare key in a secure location to avoid downtime

What are the part references and why do they matter?

This switch ships with the manufacturer references AT195301 and is cross-referenced to AR47458 and AR58126, making it easier to confirm interchangeability with OEM parts lists. Using the correct reference reduces the chance of ordering the wrong switch and ensures alignment with your machine’s electrical system.

• Primary part: AT195301 — the Solarhome SKU
• Cross-references: AR47458 and AR58126 for OEM compatibility checks
• Match your current part number or vehicle parts manual to confirm fitment
