High production, riding, concrete saw

Concrete saw comprising, in combination:

• a frame including first and second sides each having an upper surface and an inner surface;
• a shaft rotatably mounted to the frame and for carrying a sheave and a concrete saw blade;
• a carriage including first and second L-shaped carriers each including a lower surface and an outer surface;
• a first pair of slides carried by one of the frames and the carriage and sandwiched between the upper surfaces and the lower surfaces;
• a second pair of slides carried by one of the frames and the carriage and sandwiched between the inner surfaces and the outer surfaces;
• a motor mounted to the carriage and including a drive pulley;
• belts extending between the drive pulley and the sheave;
• and means for moving the carriage relative to the frame in a direction parallel to the upper, inner, lower, and outer surfaces, with the slides being formed of material to which concrete slurry does not adhere effectively so that any concrete slurry which tends to harden on the slides will break away and fall from the slides.

Concrete saw comprising, in combination:

• a chassis moveable upon a concrete surface, with the chassis including first and second rails and a seat base extending outwardly from the first rail in a direction away from the second rail;
• a cutting assembly including a saw blade, with the cutting assembly being supported by the chassis substantially between the first and second rails but with the saw blade located outwardly from the first rail in a direction away from the second rail;
• and an operator platform mounted to the seat base, with a saw cut plane defined by the saw blade extending through the operator platform, wherein the cutting assembly comprises, in combination:
• a frame, with the frame mounted for movement relative to the chassis;
• a rotatable output including a drive pulley mounted to the frame, a shaft rotatably mounted to the frame and including the saw blade and a sheave located intermediate the saw blade and the frame, a first housing including a first, generally U-shaped, axially extending wall having an inner edge and an outer edge, with the first housing extending around the sheave and closely conforming to a side of a periphery of the sheave, with the first housing including an outer, radially extending panel extending across the outer edge and having an aperture through which the shaft intermediate the sheave and the saw blade extends;
• a seal for rotatable receipt of the shaft intermediate the sheave and the saw blade and within the aperture of the panel;
• and a tongue extending across the inner edge and having an aperture through which the shaft on the opposite side of the sheave than the saw blade extends, with the first housing being carried by the frame.

Concrete saw comprising, in combination:

• a chassis moveable upon a concrete surface, with the chassis including a seat base;
• a cutting assembly including a saw blade, with the cutting assembly being supported by the chassis;
• a plurality of elastomer cushions;
• a mount;
• a seat secured to the mount;
• a footrest secured to the mount;
• an armrest mounted to the mount;
• and a joystick mounted relative to the armrest, with the joystick controlling operation of the concrete saw, with the plurality of elastomer cushions being sandwiched between the mount and the seat base.
