The Dozer Blade on the RS1000, does not tilt above and below the horizon, like a true six way blade. The cutting edge on the DB44 – Dozer Blade does have slotted holes, so you can simulate a very slight tilt action, about a 1/2″ difference from one side to the other.
If you are looking for those types of capabilities, I would look at the MAGNATRAC MH4900 or MH8500 model. Both of these models will offer the SWB54 – Six Way Blade. This blade will angle 9 degrees above and below the horizon.
