A frame type tractor having an engine mounted in a front region of a main frame extending longitudinally of a tractor body, and a transmission case mounted in a rear region of the main frame. A backhoe mounting frame is attached to a rear end of the main frame. Rollover protection system mounts are arranged in upper portions of the backhoe mounting frame for fixedly supporting a rollover protection system. The backhoe mounting frame has a frame structure defining an inside space therein and including a pair of right and left side walls, a top wall interconnecting upper ends of the side walls, and a bottom wall interconnecting lower ends of the side walls. The right and left side walls have the rollover protection system mounts and backhoe attaching portions for engaging and connecting a backhoe unit.

This invention relates to a suspension mechanism for a front mower or a mid-mount mower. A mower housing is suspended from a tractor body through a support axis extending in a fore and aft direction, and a seesaw arm pivotable about the support axis. Housing connectors, each having an elastic element such as a spring, are arranged between the seesaw arm and mower housing.

Firing process and apparatus for uniformly heat-treating a substrate having a film-forming composition thereon, wherein the substrate is subjected to a first soaking step in which the substrate is held for a predetermined time in a first heating chamber whose temperature is maintained at a first value, so that the temperature within the substrate is held at the first value evenly throughout an entire mass of the substrate, and after feeding of the substrate into a second heating chamber whose temperature is maintained at a predetermined second value which is different from the first value by a predetermined difference, the substrate is subjected to a second soaking step in which the substrate is held for a second predetermined time in the second heating chamber, so that the temperature within the substrate is held at the second value evenly throughout the entire mass of the substrate.

A dual tension clutch comprising a drive pulley, a driven pulley, and a transmission belt wound around the drive and driven pulleys. Opposite runs of the transmission belt are pressed inwardly by two spring-loaded tension pulleys supported by tension arms pivoted to each other. A triangular frame, as guided by a fixed pin, acts on the tension arms to spread the tension pulleys apart to relax the transmission belt. In the declutching state so established, the tension pulleys are opposed across and equidistant to a line extending through centers of the drive and driven pulleys.

A walking operator type lawn mower comprising a steering handle extending rearwardly thereof, a cutting blade clutch for making and breaking drive transmission to a cutting blade, and a clutch lever pivotable between a clutch engaging position adjacent the steering handle and a declutching position away from the steering handle. A manually operable interlocking member and a control device are provided between the clutch lever and the cutting blade clutch. The control device is constantly urged to a position to disengage the clutch. The interlocking member is switchable between a position to interlock the clutch lever and the control device and a position to release the two components from each other, and is constantly urged to the release position. The cutting blade clutch is engaged only when the interlocking member is maintained in the interlocking position and the clutch lever is moved to the clutch engaging position.
