It appeared the Square Turn came with an underslung Oliver 3-gang plow, as shown on this early Albaugh-Dover tractor, probably about 1917. A couple of minor differences are apparent on this tractor – a gear cover (the dome-shaped object above the word “square”) where there was none earlier and the lack of a front wheel brace (which appeared to be on earlier tractors).
A 1918 issue of Northwestern Tractor & Truck Dealer ran this photo of a Square Turn pulling a 9-ton load of hay. By this time the company had reverted to Norfolk, Neb., and was no longer affiliated with Albaugh-Dover.
This early ad shows the Square Turn being sold by Albaugh-Dover Co., but under a different rating than other ads: This displays 15-30, while most other ads show 18-35, although some say 18-30.
Square Turn tractors obviously could attach other implements besides a plow, as this 1922 photo shows the machine working with an underslung Fresno scraper on the road. Though this is a later Square Turn, it again has the front wheel braces.
When this circa 1918 ad for the Square Turn came out, it appears the tractor was only being manufactured in Norfolk again, with a sales office in Chicago. Albaugh-Dover was apparently no longer involved, as the ad states Square Turn Tractor Co.
Vital statitistics for Square Turn tractors varied: This circa 1918 ad lists specifications (not shown) both from earlier Square Turns – weight, magneto, drive wheel size – and from later ones – height, length, width and price. Pinning down exact years for information like this is often difficult.
This early ad for the Square Turn tractor, circa 1915, boasts it could turn a square corner in a field with three plows in 5 seconds. The illustration has what appears to be a front wheel brace (the white bar emerging from the central axle), and does not have a gear cover, as later illustrations do. (See the difference above the word “Square” on the image at the top of page 18, and above the word “Tractor” on this image.) It also differs saying the drive wheels are 70 inches in diameter while others say 60 or 61.
