RipRow for lower back problems

Hey Lee
Been checking out the RipRow and am very interested. Almost ready to pull the trigger and buy one. I have one major concern and I’d really like your honest input.
I’ve had a history of low back issues (herniated L4/L5 and L5/S1 discs). I even had a bout of sciatica early this year. I’m 46, am quite fit, avid MTB’r. Live in Louisville, KY, so dealing with winter conditions, freeze/thaw, riding is very limited. I get workouts in 3-4 times a week consisting of spin bike and weight training.
Before my recent sciatic flareup, I was doing a lot of kettlebell swings, good form, and I guess my back finally gave. Not doing them any longer. My concern is how extreme the RipRow is with a history of low back issues?
Can it be used conservatively to still get a great workout that translates to the trail and be safe on the low back? Sorry for the long winded message, just trying to make an informed decision. Thanks for your time.
