Abstract: A system and method for cleaning of heat exchanger tubes including an assembly, an indexer, and a communication device provided with specialized software and programming. The indexer includes orthogonally arranged first and second arms. A trolley and sensors are provided on the indexer arms. One or more lances are provided on the trolley to deliver water jets into the openings. Sensors measure displacement as the trolley is moved relative to the heat exchanger's face plate. An operator controls the system from a distance away using the communication device. During setup, the pattern of the face plate is learned and mapped utilizing information from the sensors as one of the inputs. This information is utilized to help navigate the face plate during a subsequent cleaning operation. A kit for retrofitting existing X-Y indexers is also disclosed.

Abstract: An integrated pressure washer is disclosed. The integrated pressure washer has an engine. At the bottom of the engine is an engine bottom cover. The engine bottom cover has a recess formed by a cylindrical wall that extends up from a base of the engine bottom cover. The pressure washer also has a pump assembly. The pump assembly is attached to the engine bottom cover and extends into the recess. The pump assembly receives water and applies pressure to the water and directs the pressurized water out a high pressure hose.

Abstract: A system for providing larger blades on a lawnmower, while at the same time allowing the lawnmower to be easily handled. This is accomplished while maintaining legal rpm speeds for the cutting blade.

Abstract: The present invention includes a control system for manually varying the speed of a walk behind belt-driven self-propelled lawn mower. The self-propelled lawn mower transmission is equipped with a lever for tilting the transmission for tightening or loosening the belt, and this increases or decreases the lawn mower speed.

Abstract: A braking system stopping the rotational movement of a spindles used in power equipment may have brake pads that engage the spindle. The braking system has a brake arm that pivots at one end and has a brake pad at the other end. The brake arm is connected to a spring which, when the brake system is engaged, causes the brake arm to pivot upwards and the brake pad comes into contact with a rotating spindle or pulley. For example, the pulley may be attached to a lawn mower blade. The combination of the spring pivoting the brake arm upwards as well as the rotation of the pulley towards the brake arm causes the pulley to cease rotating, bringing the rotating member to a stop.

Abstract: A wheel hub assembly for use in powered lawn equipment is disclosed. The wheel hub assembly has a receiving member which is coupled to an intermediate shaft having an intermediate gear. The intermediate gear is coupled to an output shaft having an output gear. The output shaft is connected to an output hub; the intermediate shaft gear meshes with the output gear such that when the receiving pulley is rotated in one direction, the output hub rotates in the opposite direction.

Abstract: A wing lawn mower for cutting grass is herein described. The wing lawn mower is attached to a main mower, the wing mower moveable from a lowered position to a raised position. When in the lowered position, the wing mower is driven by a wing belt, which is in turn driven by a main mower deck pulley. When the wing mower is moved to the raised position, the wing belt becomes slack. The slack causes the wing mower blades to cease turning. Then the wing mower is lowered into the cutting position, the wing belt pulled taught. When this occurs, the wing belt is guided back into place against the wing pulley by belt retainers. This allows the wing mower to be raised and lowered without having to remove or reconfigure the wing belt.

Abstract: A bypass pin for a hydrostatic transmission is disclosed. The hydrostatic transmission has a hydraulic pump. The bypass pin has a head positioned at one end of a shaft. The bypass pin also has a tip positioned at an opposite end of the shaft. The bypass pin is configured to receive a linear force exerted against the head in a first direction which causes the bypass pin to move in the first direction. The shaft of the bypass pin is configured to be positioned through a casing containing the hydrostatic transmission. The tip is configured to contact a rotating member in the hydraulic pump when the rotating member is in contact with a fluid directional member, the tip pushing the rotating member away from a fluid directional member in the first direction when the linear force is applied.

Abstract: A gradual engagement system for use in power equipment is herein described. The gradual engagement system causes a clutch pulley to rotate around a clutch arm when an engagement tensile force is applied by an engagement spring. The engagement spring is attached to a pivot arm which is also connected to the clutch arm. The gradual engagement system allows the clutch arm to be pressed against a drive belt in a gradual fashion, providing for a smooth engagement of the various components of the power equipment.
