A turplaner is described comprising a rotational elongated cutter comprising a first side and a second side and a lift mechanism capable of independently altering a cut height of the first side of the rotational cutter and the second side of said rotational cutter based on a deviation between cut height and a desired cut profile. A hierarchical controller is in functional communication with the lift mechanism wherein the lift mechanism alters the cut height based on the deviation of cut height relative to the desired cut profile in response to the functional communication. The hierarchical controller comprises a laser guidance system comprising a planer laser beam, extending over the area, and at least one laser receiver on at least one of the first side or the second side wherein the laser receiver is a laser height above the cut height and in functional communication with the hierarchical controller. The laser receiver is capable of receiving the planer laser beam and the hierarchical controller is capable of determining and minimizing a deviation between the cut height and the desired cut profile based on the laser receiver location relative to the planer laser beam. At least one autograde device is in functional communication with said hierarchical controller. An autodepth device is in functional communication with the hierarchical controller wherein the autodepth device comprises a mechanism for measuring a cut depth in the area. The hierarchical controller communicates a height adjustment based on the autodepth device if a cut depth exceeds a predetermined depth limit, the autograde if the laser receiver is not within a predetermined range and otherwise the laser receiver.

A walk reel mower has a traction frame that carries a handle assembly to accommodate users of different heights. A pivotal bail on the handle assembly allows the user to slip a traction clutch to temporarily slow the mower down when turning the mower around. The handle assembly has a resilient isolator that acts in shear to permit the traction frame of the mower to maintain the quality and the height of cut when operated by users having a heavy downpressure touch on the handle assembly. A fixed head reel cutting unit or a flex head reel cutting unit can be interchangeably carried on the traction frame using a common mount therefor. Backlapping can be accomplished in situ by using an idler wheel between a driven transport wheel and the reel of the cutting unit to reverse the direction of the reel.

A dual reel lawn mower is disclosed. The present invention discloses the line-up of two reel mowers connected by a bar that allows an more efficiently and effectively way to cut the grass on one cut with the dual action of two mowers being used. A dual reel lawn mower comprises two individual reel cutting units, one reel cutting unit is connected by a second reel cutting unit by a connection bar, wherein the first reel cutting unit and the second reel cutting unit are connected front and rear to one another disposed in a moving position. The present invention allows a user the convenience of saving time by cutting twice at one time.

A walk reel mower has a pivotal rear traction drum that can be selectively disposed in two different mowing positions that allow a single mower to cut grass on golf course greens as well as tee boxes with no degradation in cutting or power performance. The reel cutting unit has a pivotal rear shield to allow the rear shield to be pivotally adjusted to maintain its radial spacing relative to the orbit of the reel at a desired amount as the reel diameter decreases due to wear.

A turf groomer is coupled to a reel cutting unit in advance of the cutting reel and is powered by a gearbox having a rotary gear drive that is capable of selectively rotating the turf groomer in opposite directions at different speeds. The rotary gear drive is symmetrical about a plane through the axes of the input and output shafts thereof to permit the gearbox to be inverted to drive the turf groomer from either the left or right sides without requiring that two different models of the gear drive be available. The gearbox is connected to the reel cutting unit only by connecting the end of the input shaft to a shaft of the cutting reel and through a connection to a height adjuster for the turf groomer.
