Benny, I'll compare my B2650 with a BB1572 and R4 tires to my M4 with a HR3584 with R1 tires. M4 tractor weighs nearly 8,000 lbs and the HR3584 weighs 1097. The B2650 weighs 3200 and the BB1572 weighs 850 (I added 500 lbs of 1" plate steel). I just used the M4 with the HR3584 to break up a 15 year old gravel parking lot that had huge chunks of concrete, asphalt, tree trunks, cinder block, and a fence gate post set in a piece of concrete 36" x 12" (it had been cut off at ground level and I couldn't see it). I used the scarifiers to rip down about 6" to get the pot-holes. I could travel at 5.4 mph in the M4. For several years before I got the M4, I maintained the 1.3 mile unassured road I live on. It's been here for 13 years and serves 15 homes. It would take me 14 hours to blade the road, traveling at 1.6 mph (prior to adding the weight, it would take about double the time, but I could travel at a much faster speed. I can do the same road with the M4 in 4 hours traveling as fast as my back and kidneys can take.
The hydraulic rippers are all the way up or all the way down - you can't use the hydraulics to drop them down half way. I didn't need the hydraulic rippers, but I got a good deal on the HR3584. I broke one of the shanks off working on the parking lot. With shipping, that cost $40 with $50 in shipping.
Your 3350 will work, but you won't be able to just drop the blade in any material.
