During May 1990, I purchased a Model B Beaver riding tractor at the annual engine show held at Dunstable, Massachusetts. Although it was operational at that time, the entire machine had been painted and repainted with colors that were not the original ones. In addition, some of its component parts were handed to me when I bought it, and some were later found to be missing.

A request published in GEM resulted in receipt of a parts list from a Beaver owner, and a copy of the instruction book for its Wisconsin Model BKN engine was purchased from a vendor at one of the engine shows held in Massachusetts during 1990. Correct colors for the machine were determined from several owners of unmodified Beaver tractors.

According to a list of Wisconsin engine serial numbers, it appears that this particular engine was assembled during January of 1956.

Before the machine was cleaned up, and prior to its repainting, it was necessary to find a motor belt guard and a special shouldered bushing. These were located and installed, but a replacement for a missing plastic hood (4470-2401) has not been found.

About 15 months after purchasing the Beaver garden tractor, the wheels had been sandblasted, most of the frame had been smoothed down, two rear wheel fenders which were not original had been removed, gasoline leaks had been corrected, and a ball joint link had been replaced. Also, there were new rubber handles on the steering lever and on the tool control lever. Magnets in the Fairbanks-Morse magneto were recharged by John Rex.

A decal was acquired from a Beaver owner in New Hampshire and installed on the belt guard; a new Champion D-16 spark plug, together with a new ignition cable assembly, were installed. The oil bath air cleaner was cleaned and its body and bowl were repainted.

After determining the carburetor to be a Marvel-Schebler unit, I disassembled and cleaned it. Short lengths of pipe and an elbow found between the engine and its muffler were removed and the muffler was reinstalled correctly on a 21/2 long pipe nipple.

Restoration work on the Beaver tractor was completed when the machine was painted gray, the wheels yellow, and the seat red.
