Abstract: A spray gun includes a gun body and a handle removably connected to the gun body. A filter is disposed in the handle for filtering particulate from the spray fluid. A trigger guard is connected to the handle and gun body and includes a contour on a lower portion of the trigger guard for receiving one or more fingers of the user that are not interfacing with and contacting the trigger. The trigger guard can be disconnected from the gun body and rotated relative to the handle. The trigger guard can contact a portion of the handle and exert torque on the handle to connect the handle to and disconnect the handle from the gun body. The portion of the handle at least partially covers a fitting connecting to the handle to provide spray fluid to the spray gun.

Abstract: A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

Abstract: A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.

Abstract: A material sprayer includes a hopper module and a power module. The power module is mountable and dismountable from the hopper module. The hopper module includes a hopper frame and a hopper supported by the hopper frame. The power module includes a drive and a pump connected to and configured to be powered by the drive. The pump interfaces with the hopper with the power module mounted on the hopper frame such that the pump can draw material from the hopper.

Abstract: A drive system for a fluid displacement pump includes an electric motor, a drive coupled to the rotor at a first end of the electric motor, a pump including a fluid displacement member mechanically coupled to the drive, and a controller configured to control a level of power to the electric motor based on a pressure setting set by a user. The electric motor includes a stator and a rotor disposed on an axis. The drive coupled to the rotor converts the rotational output to a linear, reciprocating input to power a pump.

Abstract: A ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

Abstract: A transfer pump includes a drive module having electronic components and a fluid module not including electronic components. The drive module provides motive power to a pump of the fluid module to power pumping by the fluid module. A control module is configured to monitor operation of the transfer pump and control pumping by the transfer pump. The control module is configured to receive dosing commands from a user interface, recall a dosing parameter based on the dosing command, and cause the drive module to operate the fluid module based on the dosing parameter to cause the transfer pump to output a set volume of material.
