Abstract: This invention relates to a riding mower comprising a chassis supporting a driving unit intended to propel the wheels of the mower as well as a cutting attachment, the cutting attachment being movably fastened to the chassis and by means of an operating device can be brought from a lower cutting position to an upper non-cutting position. The cutting attachment has an upper and a lower displacement area, the engagement and disengagement of the cutting attachment being effected in the upper area, whereas the cutting attachment in the lower area can be moved upwards or downwards with its parallelism with the ground preserved and can be locked against downwards movement for different cutting heights. The mower is driven while the cutting attachment is in the lower displacement area.

Abstract: In a forward engine compartment of a vehicle a power unit is suspended so as to have a controlled rearward movement in the engine compartment when exposed to excessive forces in the lengthwise direction of the vehicle during a collision. There is at least one rear mounting having a resilient body separating two members secured to the power unit and to structural portions of the vehicle body, respectively. Said rear mounting allows one of the members a limited movement relative to the other while absorbing deformation work. As the power unit travels further back the attachment of the rear mounting is gradually destroyed, but it holds long enough to allow the power unit to hit a cowl panel at the rear of the engine compartment, thus controlling the travel of the power unit.
