I have a HD 6' box blade (traded up from a lighter unit with hydraulic scarifiers) with super HD hydraulic scarifiers
B U T today I bought a 7 foot rear blade (King Kutter $199) expecting it to do some things better/easier than box blade. 1. Backfill ditches since it pivots side to side, 2. snow plow (I can turn it around and back up going blade first if I want and with 4wd don't expect it to change traction situation much and again it pivots to move snow to the side. 3. if I just want to do some light grading and not drag dirt any distance it is wider 7' vs. 6' so it covers my tracks better and with TNT I expect to get finer control without plowing a pair of furrows. My box blade is so big (how big is it?) It is so big that if I tilt it forward for fine dumping control (much finer control than 3pt) and go very far the front of the box digs a couple furows. With tilt and 7 ft width I should be able to dress a crowned road in two passes this will become more important soon. It is a requirement before a contractor will start construction on my site to have an all weather road in addition to water and electricity. I get to build/maintain the road.
