according to cat tool bar manuals chisels and subsoilers must operate in float, even when gauge wheels are used. i'd say your case the bigger the machine and hd built tool etc and only running 8-12 inches go for it. flat land work will keep it close to constant depth.

The D4E for example...does not use a float position valve for the parallel linkage ripper. I don't believe you would want that feature as the ripper/scarifier teeth would bury itself to the hilt.

My 3-pt on the D4 utilizes the the single valve #44 with float valve but I seldom use the float feature.

The Cat scarifier on the HT4 is connected to the non float valve of the two valve #44 system and is controlled by a "transflo valve" to isolate it from the loader cylinders.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
