This is my setup: hydraulic toplink, hydraulic sidelink, 3 OEM valves in the slots between the seat and right fender. Two center return, one float so I can float either the toplink (handy for bush hogging rough areas) or sidelink (useful for some grading situations where you want the tilt of the blade to follow the crown of a road where crown varies through curves and straights). Dealer installed about a two years after I bought the tractor.
Hindsight: should have spec’d them with original purchase. Didn’t know how useful they’d be and underestimated the amount of grading I’d be doing maintaining roads, trails, and ditches.
I’ve used various 3 point implements on a variety of tractors for about 50 years. This is the first I’ve used with hydraulic toplink or sidelink. For some of my implements, it has absolutely zero benefit (chipper, stump grinder, generator, skidding winch, trailer mover). For others, it’s an incredible increase in function and efficiency (box blade, back blade, pine straw rake). For a bush hog type cutter, it might or might not be an improvement depending on what you do with it.
For the most part, it’s not an improvement for set and forget type implements. For things such as box blade and back blade where being able to adjust quickly is an advantage and being able to adjust while moving increases functionality of the implement, they’re worth every penny plus some. Bottom line, IMO depends on what you’ll be doing with it whether it’s worth the money.
If you’re doing any blade work at all, I’d suggest getting a hydraulic toplink and sidelink. If you don’t want to spend the money on the full setup, at least get a hydraulic toplink if you can.
Also, consider whether you want to be able to float the cylinder(s). If you don’t, consider getting cylinders with check valves (holds the cylinder where you set it even if the control valve is a bit leaky, which it probably will be). There are some really smart folks here who can walk you through a DIY setup. I’m not one of them.
