Mounting apparatus for offset mower

Claim 2

A mower mounting apparatus for mounting a mower at the side of a vehicle, comprising: linkage means for connecting with the vehicle pivotally mounted about first pivot means for vertical pivoting movement of the linkage means to raise and lower the mower; said linkage means being pivotally mounted about second pivot means for pivoting movement of the linkage means to allow non-rotational rearward translation of said mower connected with the linkage means when the mower strikes an obstacle.

Claim 3

The mower mounting apparatus as set forth in claim 1, wherein: the linkage means includes a mower connecting means secured to the outer distal portion of the linkage means by the first pivot means for securing said mower thereto.

Claim 4

The mower mounting apparatus as set forth in claims 1 or 2, wherein: the linkage means includes hydraulic cylinder means to retain the linkage means from horizontal pivoting movement about the second pivot means.

Claim 5

The mower mounting apparatus as set forth in claim 1, wherein: the linkage means includes a hydraulic cylinder to effect vertical swinging movement of the linkage means about the first pivot means.

Claim 6

The mower mounting apparatus as set forth in claim 2, wherein: the mower connecting means includes third pivot means for connecting said mower thereto for vertical swinging movement of the mower about the third pivot means.

Claim 7

The mower mounting apparatus as set forth in claim 5, wherein: the linkage means includes a hydraulic cylinder to effect vertical swinging movement of the mower about the third pivot means.

Claim 8

The mower mounting apparatus as set forth in claim 1, wherein: the linkage means includes upper and lower parallel links.

Claim 9

The mower mounting apparatus as set forth in claim 1, wherein: the linkage means includes a vehicle connecting means secured to the inner proximal portion of the linkage means for securing to a vehicle.

Claim 10

The mower mounting apparatus as set forth in claim 3, wherein: the hydraulic cylinder means includes a relief valve to allow fluid to be displaced from the hydraulic cylinder means at a predetermined pressure upon horizontal pivoting movement of the linkage means when the mower strikes an obstacle.

Claim 11

The mower mounting apparatus as set forth in claims 4 or 6, including: a two spool hydraulic control valve to regulate fluid supplied to the hydraulic cylinder.

Claim 12

The mower mounting apparatus as set forth in claim 1, wherein: the linkage means includes a first hydraulic cylinder to effect the pivoting movement about the first pivot means and a second hydraulic cylinder to retain the linkage means from pivoting movement about the second pivot means; a hydraulic control valve having a fluid supply line to regulate fluid to the first hydraulic cylinder; and said second hydraulic cylinder having a second fluid supply line connected to the hydraulic control valve fluid supply line whereby actuation of the hydraulic control valve to regulate the first hydraulic cylinder will automatically supply fluid to the second hydraulic cylinder.

Claim 13

The mower mounting apparatus as set forth in claim 11, wherein; the second fluid supply line has a relief valve to allow fluid flow at a predetermined pressure through the second supply line when the linkage means is pivoted to allow non-rotational translation of the mower when the mower strikes an obstacle.

Claim 14

The mower mounting apparatus as set forth in claim 1, wherein: the linkage means includes upper and lower parallel links to maintain the mower at the same inclination upon pivoting of the linkage means about the first pivot means.

Claim 15

A mower mounting apparatus for mounting a mower at the side of a vehicle, comprising: a vehicle connecting means for securing to the side of a vehicle; a plurality of vehicle connecting brackets secured with the vehicle connecting means for vertical pivoting movement of the brackets in a vertical plane; a plurality of parallel links pivotally mounted at their proximal ends with the brackets for vertical pivoting of the links with the brackets and for pivoting movement of the links relative to the vehicle connecting brackets in a second plane perpendicular to the vertical plane. a plurality of mower connecting brackets pivotally mounted at the distal ends of the links for pivoting movement of the links relative to the mower connecting brackets in the second plane; and said mower connected with the mower connecting brackets to allow non-rotational rearward translation of the mower through pivoting of the links in the second plane when the mower strikes an obstacle.

Claim 16

A mower mounting apparatus for mounting a mower at the side of a vehicle, comprising: a vehicle connecting means for securing to the side of a vehicle; a plurality of vehicle connecting brackets secured with the vehicle connecting means for vertical pivoting movement of the brackets in a vertical plane; a plurality of parallel links pivotally mounted at their proximal ends with the brackets for vertical pivoting of the links with the brackets and for pivoting movement of the links relative to the vehicle connecting brackets in a second plane perpendicular to the vertical plane. a plurality of mower connecting brackets pivotally mounted at the distal ends of the links for pivoting movement of the links relative to the mower connecting brackets in the second plane; and said mower connected with the mower connecting brackets to allow non-rotational rearward translation of the mower through pivoting of the links in the second plane when the mower strikes an obstacle.

Claim 17

The mower mounting apparatus as set forth in claim 14, including: a first hydraulic cylinder to effect pivoting movement of the brackets and links in the vertical plane; and a second hydraulic cylinder to retain the links from pivoting movement in the second plane.

Claim 18

The mower mounting apparatus as set forth in claim 15, including: a hydraulic control valve having a fluid supply line to regualte fluid to the first hydraulic cylinder; and said second hydraulic cylinder having a second fluid supply line connected to the hydraulic control valve fluid supply line whereby actuation of the hydraulic control valve to regulate the first hydraulic cylinder will automatically supply fluid to the second hydraulic cylinder.

Claim 19

The mower mounting apparatus as set forth in claim 16, wherein: the second fluid supply line has a relief valve to allow fluid flow at a predetermined pressure through the second supply line when the plurality of links are pivoted to allow non-rotational translation of the mower when the mower strikes an obstacle.
