All these types of saws were gradually supplemented and then replaced relatively quickly two-man chainsaw MP-50506 domestic production. It belonged at that time still saw the MP-50 to the best saws in its category in Europe. It had a standing two-stroke single cylinder with a bore and a stroke of 68 mm, volume 248 cm3 and 5.5 hp (4 kW) at 3,800 rpm. It was equipped with a decompression valve for easier starting and stopping of the saw. The circumferential speed of the chain reached 7 m / s, the cutting joint was 8 mm wide. The saw had a gradient petrol tank, Jikov 2920 PS float carburetor, 2.5 l petrol tank, oil tank 0.5 l, automatic chain lubrication with gear pump. Together with a bar with a length of 600, 800 or 1,000 mm weighed 38, 40 and 42 kg, respectively. The cylinder was aluminum with a cast iron insert, gear the ratio between the motor and the chain was 3.2: 1 and the clutch was centrifugal. Starting flat the belt did not have automatic rewinding.

A saw equipped with a float carburetor could not be tilted, if necessary therefore, only the bar tilted. The design of the MP-50 allowed three positions of the bar: vertical for cross-sectional cuts; horizontal for felling; oblique for cutting jams (alternatively 30 ° or 45 ° from the horizontal). The cutting chains of the time were not adapted for oblique cutting, and so the saw had to be pushed into the oblique cut by force, so it was an unpopular execution oblique cuts necessary when creating a jam. Changing the position of the felling and cross-section bar was only possible with the chain standing, which complicated and delayed the work. This was one of the reasons why the trees up to 20 cm on the stump were felled without a jam, only the third member of the group pushed them in the direction of the fall of the poles. Trees with a thickness on the stump of 20–30 cm were cut after a previous horizontal cut with a saw instead of a jam, and for trees thicker than 30 cm on a stump, two cuts were made with a saw against the future main section, spaced vertically 3-4 cm. Sometimes the space between the notches protruded with an ax or thicker trees were felled with a jam made by an ax.

History from the WYCO web site:

In 1921 Andrew Wyzenbeek organized a group of engineers to form the Wyzenbeek & Staff Company, and by 1929 his company was fully dedicated to the production of flexible shaft machines and power tools for the industrial market. The flexible shaft with offset bearings was an innovative concept, and Wysenbeek utilized this principle in a number of products, from fish scalers to concrete vibrators. Wyzenbeek began the production of gas-powered vibrators in 1941. In 1962, Wyco, as the company became known, received a patent on its Square HeadTMvibrator design, the patent awarded for consolidation efficiency. The concept was further supported by conclusions of the IIT Research Institute (IITRI) of Chicago. In 1970, Wyco introduced the world's first hydraulic concrete vibrator for use on concrete paving equipment. In 1971, Wyco was purchased by Racine Federated Inc., a private manufacturing company under the leadership of John Erskine Sr. With the introduction of its high-cycle vibrator in 1975 and its pneumatic vibrator in 1977, Wyco developed a core family of internal concrete vibration products that continues to this day. The first portable gas vibrator was unveiled in 1981, and in 1986 Wyco introduced the first UL/CSA approved concrete vibrator, the first of its kind to meet OSHA standards. In 1994 the hydraulic concrete vibrator was dynamically redesigned to meet changing mix standards for the pavement industry. Wyco worked closely with specifying agencies to develop placement standards ultimately adopted for highway and runway construction. Wyco also introduced the smart vibrator system, a PC application for continuous vibrator monitoring on hydraulic pavers. In 2004, Wyco introduced the first full-powered adjustable speed high-cycle vibrator capable of meeting all placement requirements for bridge construction. 2010 was an innovative year for Wyco. The company introduced the Sure Speed Electric vibrator that automatically adjusts to maintain the same speed in the mix, regardless of the load placed on the head. This technology provides users with minimal surface defects which in turn reduces patching costs. In January 2011, Wyco acquired the Screed King from Crown Construction Equipment. The acquisition represents an expansion of the divisions’ concrete products. Wyco is continually striving for success within its products and services. Today, Wyco continues to monitor mix and material compatibilities in the concrete industry, and the dynamics of placement by vibration. Wyco's people are proud of the company's long history, and they are excited to continue the company's tradition of innovation, for their industry and for their customers.

PM REDHEAD.

PM REDHEAD....ONE MAN SAW.




Upon bankruptsy of the former IEL company was created the new PM (POWER MACHINERY) company with former employees from Vancouver, Canada.
The Redhead was a very rare saw with limited production(3,600) due to the lack of power and unatractive to buyers. Later models of the WR series upgraded this saw with a more powerful engine (7HP) with a bigger bore and heavy duty gear housing.
This saw is from the initial early version and very rare.
