the central region of the strut 52 is connected through a joint 54 with a side leg 31 which projects downwardly from the lift arm 30 for this purpose the strut 52 is provided with a bore which receives a pin this pin is the same pin that couples the lift arm 30 with the hydraulic motor 34 in contrast to previous commonly used pins the pin used here is an extended length pin which extends through the bore of the strut 52 appropriate rapid release retaining elements not shown may be used to secure the pin to the strut 52 as long as the two struts 52 and the two links 42 are not permanently fastened to the vehicle 10 then the vehicle 10 does not differ to a notable degree from a conventional tractor with hitch for the pivoting of the operator 39 s platform 20 the struts 52 and the links 42 are fastened to the vehicle in the manner shown and described furthermore attaching elements that secure the operator 39 s platform 20 to the vehicle body 36 are released if the power motors 34 are supplied with pressurized hydraulic fluid and are extended the forward part of the operator 39 s platform 20 is raised from the vehicle body 36 permitting access to vehicle components located underneath the operator 39 s platform 20 the struts 52 the links 42 and an electric or manually operated external hydraulic pump can be assembled and held as separate unit so that it can be fastened to the vehicle if necessary in order to pivot the operator 39 s platform 20 for the hydraulic.
