A turf aerator has a chassis and a motor mounted on the chassis between a front end and a rear end of the chassis and between a first side and a second side of the chassis. A first shaft is rotatably driven by the motor, a first inner tine assembly mounted to a first portion of the first shaft, a second inner tine assembly mounted on the first shaft, and a first outer tine assembly mounted to a second portion of the first shaft. A tine cover is removably secured to the chassis over at least one of the first inner tine assembly and the first outer tine assembly.

Turf aerator with covered tine assembly

Tines () of tine assemblies () are secured by a single bolt () extending diametrically through each tine () located in a cavity () of a tine plate (), through the tine plate () and through an attachment ring (). The attachment ring () of an outer tine assembly () is connected to a sleeve () rotatably mounted adjacent the outer ends on each of two independently rotatable shafts () to which inner tine assemblies () are rotatably connected adjacent the inner ends of the two independently rotatable shafts (). The attachment rings () of the inner tine assemblies () are welded to the two independently rotatable shafts ().

Driven and non-driven rotatable tine assemblies for a turf aerator

Tines () of tine assemblies () are secured by a single bolt () extending diametrically through each tine () located in a cavity () of a tine plate (). An outer tine assembly () is connected to a sleeve () rotatably mounted adjacent the outer ends on each of two independently rotatable shafts () to which inner tine assemblies () are rotatably connected adjacent the inner ends of the two independently rotatable shafts (). Thus, the outer tine assemblies () are located intermediate the inner tine assemblies () and the outer ends of the two independently rotatable shafts ().

Turf aerator having driven and non-driven rotatable tine assemblies

Tine assemblies () are secured by a single bolt () extending diametrically through each tine () located in a cavity () of a tine plate (). An outer tine assembly () is connected to a sleeve () rotatably mounted on independently rotatable shafts () to which inner tine assemblies () are connected. A tine cover () removably closes an opening () in the top plate () and in which weights () are removably received over the tine assemblies (). Transport wheels () are moveable by pivoting a stop plate () to position an upper pivot axis () of an abutment bar () ahead of or behind the stop axis () and lower pivot axis (). A stop () positioned on the stop plate () without the use of tools adjusts the depth of the tine assemblies ().

Turf aerator having removable cover over rotatable tines

A top dresser advances sand contained in a hopper on a dispensing conveyor moving at a linear speed onto a rotatable spinner rotating at a rotating speed. The linear and rotatable speeds are controlled by a controller by electrically actuating first and second electrically actuated valves providing fluid flow to hydraulic motors driving the rotatable spinner and the dispensing conveyor. The rotatable and linear speeds are inputted into an electrical display electronically connected to the controller. The hydraulic flow to the second electrically actuated valve may be solely from the first electrically actuated valve to create back pressure acting as a cushion. Multiple function switches on the electrical display may be actuated in sequence to replicate a linear line relationship between the rotational and linear speeds. Start-up, run, look up and application calculation screens may be displayed on a monitor of the electrical display.

Apparatus for aerating turf including positionable transport wheels

A seeder () includes multiple cutting head units () pivotally mounted to a jack shaft () of a frame () and spring biased downwardly by hold downs (). Each multiple cutting head unit () includes multiple roller blades () received on an axle () rotatably mounted in a carrier () and in gearing relation to the jack shaft (). The roller blades () include a series of oppositely formed, circumferentially spaced radially extending indentations () extending from a continuous, smooth periphery at a constant extent from the axle (). Fingers () extending between the roller blades () are pivotally mounted to the carrier () to adjust the depth of the slits formed by the roller blades (). Each hose () extending from a seed box () diverts seed into adjacent slits immediately after the roller blades ().

Turf overseeding apparatus and methods

A top dresser () includes sheeting () in the form of an endless belt passing around first and second drums () and a bed () including a plurality of rollers (). Continuous V-shaped guides () are received in pulleys () on the drums () for tracking the endless belt. A blocking device () in the form of a rod is slid in the mid-frame () to prevent the shafts () of the rollers () from axially sliding against their bias from their operative positions to their installation positions. Ledges () having friction reducing strips () extend over the shafts () of the rollers (). A compound gear () in gearing relation with the second drum () and in driving relation with a spindle () of a brush () is rotatably mounted to an arm () pivotally mounted to the second drum (). The spindle () includes two portions () removably connected by a coupler (), with the first portion () being cantilevered supported from the side frame ().

Top dresser

A broadcast spreading top dresser ( ) includes a diverter ( ) which can be positioned in an upper position for light applications and a lower position for heavy applications, with the diverter ( ) extending through a slot ( ) in an upper sheet ( ) of the spinner assembly ( ) and beyond and below the upper sheet ( ) in the lower position. The leading edges ( ) of the diverter ( ) are spaced from the circular disks ( ) of the spinners ( ) intermediate the radial position that the material is dispensed unto the spinners ( ) and the maximum rearward extent of the circular disks ( ). The lower edges of the diverter ( ) extend at differing distances into the thickness of the propelled top dressing material. The metering gate ( ) is prevented from being inadvertently manually pivoted between first and second ranges of spacings from the conveyor ( ) by a stop ( ) having a spring based plunger ( ), with the free end of the plunger ( ) sliding on the face of the side plate ( ) of the metering gate ( ) in the second range while the plunger ( ) abuts with an edge of the side plate ( ) in the first range.
