An apparatus applies product and includes a pivotal platform solely supported through bushings formed of compressible material. The ground speed can be locked by stepping on a step pivoting a composite block to engage with an engagement of the transmission proportioner arm. A gate is opened utilizing a control lever pivotally mounted to a pivotably mounted control block to either engage or avoid a tang of an adjustment guide. A drive belt system includes a variator having first and second sheaves having variable effective diameters when their pivot pin is moved by pivoting a lever. A spray tip sprays a fan style spray at a small acute angle to the application area. A flip shield is pivoted about an axis parallel to the movement direction and includes a linear straight portion parallel to the axis in a redirection position.

Methods and apparatus for applying product

An apparatus () applies product in liquid or granular form to an area and includes a pivotal platform () solely supported to a vehicular portion through bushings () formed of compressible material to reduce operator fatigue. The apparatus ground speed can be locked by stepping on a step () pivoting a composite block () to engage with an engagement () of the transmission proportioner arm (). A gate () of the hopper () is opened utilizing a control lever () pivotally mounted to a pivotably mounted control block () to either engage or avoid a tang () of an adjustment guide ().

An aerator that allows the operator to make a turn with the machine while the tines are still in contact with the turf through the use of a differential shaft and brakes that enhance the maneuverability of the machine. The aerator is fitted with a mechanical gear type differential on an intermediate drive shaft that provides for automatic, separate and variable rotational motion of the individual halves of the tine shaft. This differential apparatus also provides constant and equal torque application to both sides of the tine wheel assembly simultaneously while the machine is operating. This insures that tine penetration into the turf is equal on both sides at all times. The tine shaft halves are designed and mounted in such manner as to allow each half (left and right sides) to be driven by separate chains from the differential shaft. This design results in a desired variation in the speed of rotation of the two halves that facilitates turning the unit. The differential mechanism is also functional in driving the transport rollers at the front of the machine. The improved aerator is also fitted with brakes installed on each side of the unit which can reduce the speed of rotation of the separate tine wheel halves and the individual drive rollers on the front of the unit, thus increasing the steering efficiency and a spring-actuated lift assist to help the operator raise the unit into the transport position. The aerator includes heavy duty springs on both sides of the unit to apply equal forces to both of the transport wheel lift members. A release mechanism operated from the handle bar is provided to allow the operator to disengage the retaining latches, which will allow these springs to pull the transport wheels under the unit thus raising the tine shaft halves. The aerator also incorporates drums of sufficient mass so as to not require the addition of water or other additional weighting methods.

Method and apparatus for an aerator with differential, steering assist and power lifting

A sod cutting machine in combination with turf cutting mechanism for cutting a longitudinally elongated trench in turf that has a trench bottom transversely inclined relative to the slope of the soil transverse to the direction of the trench elongation. The sod cutting machine has mounting arms mounted to the machine frame to extend vertically downwardly in a turf cutting position the same distance. The turf cutting mechanism includes first and second vertical knives that each has a rear shank portion joined to the lower end of the respective arm, a generally horizontal bottom edge portion and a front inclined sharpened edge that intersects with the bottom edge portion. A transverse bottom cutting knife extends between and is joined to the first and second vertical knives with one end portion vertically more remote from one of the arms than the other cutting knife end portion from the other one of the arms.

Triangular cross section trenching apparatus for edging

A mobile sod cutting machine has mounting arms that have a central axis of elongation with a cable installer mechanism mounted to the lower end of one of the arms for being reciprocated with the arm. The cable installer mechanism includes a vertical ground slitting blade having a front slitting edge, a bottom edge intersecting the slitting edge and a shank mounting portion mounted to the mounting arm. An upper cable guide is attached to the shank mounting portion to extend rearwardly of the central axis of elongation of the mounting arm while a bottom cable guide is mounted to the blade adjacent to the intersection of the blade bottom edge and slitting edge to have its reversely bent edge forwardly of the central axis of elongation but spaced rearwardly of the blade bottom edge along the guide length by a distance about as least as great as the reciprocal fore and aft movement of the blade. A supply of flexible cable is mounted to the machine to extend through the cable guides and be buried as the blade moves forwardly in the ground.
