Abstract
A frame apparatus that fits on the loader arms of a skid steer front loader. This frame apparatus serves as a platform upon which a plurality of hydraulically driven tools can be employed. The frame apparatus further includes a hydraulic junction box and solenoid system for multiplying the front loaders hydraulic ports.
Claims16
A multiple tool attachment for use on a front end loader having a first and second loader arm and a hydraulic system said attachment comprising:
- a base having a generally flat front surface and a rear surface adapted for attachment to said first and second loader arms so as to span the distance between said first and second loader arms on said front end loader;
- an attachment plate having a forward and rearward end said rearward end being fixedly attached to said bases front surface such that said attachment plate extends perpendicularly outward from said base in a fixed position;
- a pivot point at said forward end of said attachment plate;
- an implement bar pivotally attached to said pivot point;
- and
- an adjustment means having a first and second end with said first end pivotally attached to said base and said second end pivotally attached to said implement bar such that said adjustment means may be used to adjust the position of said implement bar relative to said base.

A hydraulically adjustable multiple tool attachment for use on a front end loader said attachment comprising:
- a base having a generally flat front surface and a rear surface adapted for attachment to said first and second loader arms so as to span the distance between said first and second loader arms on said front end loader;
- an attachment plate having a forward and rearward end said rearward end being fixedly attached to said bases front surface such that said attachment plate extends perpendicularly outward from said base in a fixed position;
- a pivot point at said forward end of said attachment plate;
- an implement bar pivotally attached to said pivot point;
- a hydraulic junction box mounted to said multiple tool attachment said junction box having a first and second primary port for attaching said junction box to the hydraulic system of said front end loader, a first and second secondary port and a first and second cylinder port;
- and
- a hydraulic cylinder attached to said first and second cylinder port on said hydraulic junction box, said cylinder having a first and second end with said first end pivotally attached to said base and said second end pivotally attached to said implement bar such that said cylinder may be used to adjust the position of said implement bar relative to said base.
