DOES ANYONE KNOW IF THERE IS A TRACTOR ATTACHMENT THAT CAN DIG A DITCH OR TRENCH ON THE SIDE OF A TRACTOR FOR DRAINING WATER ON THE SIDE OF A ROAD. I CANNOT GET CLOSE ENOUGH TO THE SIDE OF THE ROAD WITH THE TRACTOR TO EFFECTIVELY USE A BACK HOE. I HAVE TRIED A BACK BLADE ADJUSTED TO TIP ON ONE SIDE BUT IT DOESNT SEEM TO GET MORE THAN A FEW INCHES DEEP. DOES ANYONE HAVE ANY IDEAS THAT MAY HELP?
