Restoring Two Allis Chalmer L Crawler Tractors

Steel, rust, and a mystery under every hood!

You rescue two vintage crawler tractors from the same property, and neither badge matches what’s actually under the hood. Welcome to the world of old iron, where decades of field repairs create puzzles that stump even seasoned collectors.

Kyle Christ used a John Deere 210G excavator and lowboy trailer to extract two Allis-Chalmers L crawlers from a tight, overgrown property. But nothing prepared him for the identity crisis waiting beneath the rust.

An L Badge Hiding Diesel Secrets

First machine loaded, first surprise discovered. This crawler wore an “L” badge suggesting standard gasoline power. But the engine told a different story. Three separate exhaust manifolds, injector ports where spark plugs should be, and a block-off plate where an injection pump once lived revealed this was actually an LO diesel, later converted to gas.

Someone had also fabricated homemade steering levers from flat iron and welded rods, replacing the original steering wheel. Practical? Absolutely. Original? Not even close. Unfortunately, this engine has seized solid, meaning serious work lies ahead.

An LO Badge on a Gas Engine

Confusion compounded with the second tractor. This one displayed “LO” badging but featured two carburetors feeding one massive intake manifold serving all six cylinders, with just two exhaust outlets. Pure gasoline power, never diesel.

This machine came with an impressive 10-foot Baker blade weighing 4,200 pounds, equipped with hydraulic systems powered by a pump driven off the transmission. Unlike its seized sibling, this engine turns over freely, offering real hope for revival once the fuel system gets cleaned.

Solving the Mystery

How did both machines end up wearing wrong badges? Most likely explanation: somewhere in their working lives, these tractors traded radiators or sheet metal assemblies during field repairs. When parts were scarce and work couldn’t wait, farmers swapped components between machines without concern for matching badges. Productivity trumped documentation every time.

What’s Next

Christ plans to tackle the free-turning machine first. As for that battle-scarred Baker blade showing decades of broken welds and repairs? Despite its historical significance, it may see the cutting torch rather than restoration. Sometimes preservation means knowing when equipment has given all it can.
