The land pride that was listed is a good blade. Rhino (models 950 & 1540) and Woods (models RB850 & RB900) also make good rear blades as well. For your application besides adjusting angle and tilt, you will need to have offset adjustment as well. For occasional use, these can be adjusted manually; however, if they will be used frequently, the adjustments can also be performed hydraulically. Obviously, hydraulics add to the blade cost.
