History

The M4 was built by tractor manufacturer
Variants
- M4: base model. 2,464 were configured to tow the 90 mm antiaircraft gun, while 3,088 were configured to tow the 155 mm gun or 8-inch howitzer
- M4C: The "C" designation indicates spare ammunition racks configured in the crew compartment.
- M4A1: The "A1" modification designates the wider suspension used for the "duck bill" tracks mirroring the E9 modification on Sherman tanks. 259 were built in 1945, and were used post-war as a prime mover for the M23 ammunition trailer in M40 gun motor carriagesections.
Civilian use
After the war many types of these tractors were stripped of their military components and used for log skidders and power line construction. Many were used as carriers for rock drills, used in logging road construction in British Columbia. The first prototype was designed in the early 1960s by G.M. Philpott Ltd. of Vancouver, BC, and Scott-Douglas Industries, who supplied the M4 Carrier. It was used by MacMillan, Bloedel, and Powell River Company at their Juskatla, BC logging operation. Many improvements were made and when Finning Tractor later bought G.M. Philpott, the machine became the Finning Tank Drill. At least 500 were built, many of which are still in service. The original Finning Tank Drill was replaced by the M32F and M40F Tank Drills, which used larger Sherman tank carriers.[citation needed]
At Amsterdam Airport Schiphol in the Netherlands, at least two refurbished M4s were used by the airport fire brigade in the 1960s and '70s. During the mid-80s and into the early 90s, many M-4s were converted into exhibition vehicles used for car crushing and dubbed "monster tanks", William Townes's "Virginia Beach Beast" Chevrolet K-5 Blazer being among the first.[2]
