This is one of those items my hydraulic toplink is so good for. My KK subsoiler is very sensitive to the angle for penetration - too far either way and it won't dig well even in softer ground. My toplink allows me to tweek the angle on the go, which by the way is very slow - I use 1st or 2nd gear at slower engine speed as well to use the plow and it has worked fantastic in many different applications. It's great for burying wire or flexible pipe. Toplink angle is so important on boxblade work, tiller work or plowing - I can't imagine having to make manual adjustments to use these implements to their fullest.
