초록 ▼

A sod laying self propelled apparatus having a mobile frame mounted on front and rear wheels. The frame has front and rear sections that are articulated to allow the wheels to follow rough terrain. The frame front section has a U-shaped opening to allow receipt of a roll of sod therein without lifting the roll. The frame includes sod lifting arms with a two way hydraulic cylinder to raise the roll once in the roll is in the opening and in such a manner as to generally evenly distribute weight of the roll to each of the wheels. The front wheels are swingable between outside and inside positions relative to front frame arms to change the configuration thereof and include a locking mechanism to lock the configuration. The sod lifting arms are also engageable with a cross bar on a transport truck to allow the apparatus to be rotated relative to the sod raising arms and lifted from the ground for transport. A removable forklift is mountable on the frame for removing sod from a transport truck. Each of the wheels includes a hydraulic motor and the front wheel motors may be reversed depending on their configuration to allow all the wheels to drive in the same rotational direction.

[ What is claimed and desired to be secured by Letters Patent is as follows:] [1.]1. A sod lay apparatus comprising:a) a structural frame having a pair of spaced apart frame arms; said frame arms being fixed in generally parallel relation with respect to each other;b) a first pair of ground engaging wheels with each of said first pair of wheels mounted on a respective frame arm; each of said first pair of wheels being rotatable relative to a respective frame arm so as to be selectively positionable on opposite sides of a respective frame arm such that said first pair of wheels has a widened configuration wherein each wheel is positioned on an outer side of a respective frame arm and a narrowed configuration wherein each wheel is positioned on an inner side of a respective frame arm such that the apparatus is configured to pass through comparatively narrow obstacles;c) a third ground engaging wheel supporting said frame opposite said arms;d) a pair of spaced sod lifting arms; said sod lifting arms being located between said frame arms and being pivotally mounted at one end to said frame and being adapted to engage a roll of sod at an opposite end; ande) a hydraulically operated cylinder operably connected to said sod lifting arms and said frame, such that said sod lifting arms are adapted to selectively raise, support and unroll a sod roll.
