A reciprocating saw blade comprises an elongated substantially flat body having a tang end and a distal tip end, a back edge and a spaced apart cutting edge. The cutting edge is formed of first and second pluralities of alternately and oppositely facing slicing teeth which define gullets formed therebetween. The first plurality of the slicing teeth extends from the one end and merges into the second plurality of the slicing teeth which extends to the other end. Each slicing tooth includes a slicing face facing one end, a planing face facing the other end, and a tip including an uppermost planar surface. The tips of the second plurality of teeth are substantially tangent to a first tooth tip tangent line. Each tip surface of the second plurality of teeth lies at a greater angle to the first tip tangent line than the tip surface of the first plurality of teeth. A method of making a reciprocating saw blade in accordance with the present invention is also disclosed.

A cab heating system for material handling equipment which maximizes energy savings by utilizing the heat generated during hydraulic operation. The cab heating system has a hydraulic control unit which controls a material handling implement. A heat exchanger is positioned downstream of the hydraulic control unit. Air flowing through the heat exchanger is heated by the hydraulic fluid and blown by a fan into the interior of the cab. The heating system can also have an auxiliary heat exchanger to further heat the hydraulic fluid. In one embodiment, the auxiliary heat exchanger utilizes engine coolant heated by the vehicle's engine. In another embodiment, the auxiliary heat exchanger utilizes hot exhaust gases from the vehicle's engine. A cooler can be provided to cool the hydraulic fluid. A control valve assembly with a temperature sensor can also be provided to sense the temperature of the hydraulic fluid entering the control valve assembly and to direct the hydraulic fluid to the auxiliary heat exchanger when the temperature of the hydraulic fluid is below a predetermined level or to the cooler when the temperature of the hydraulic fluid is above the predetermined level.
