We have had a lot of good information on boxblade blades in the recent thread entitled "Yet Another Boxblade Question". There are also a lot of issues that I think it would be useful to discuss regarding the scarifiers.
As I understand it, there are three types of scarifier set-ups. The common one is scarifiers that are fastened by pins and that must be individually lowered. On more expensive regular boxblades and on rollover boxblades, there is a lever that lowers all the scarifiers at once. At the high end, there are hydraulically operated scarifiers.
Not having many actual boxblades to look at in this part of the country, I think it would be informative to get info on the following questions:
1. On the individual scarifier models, how many pin "depth" placements are there on your models?
2. Re individual scarifiers, some people have complained about their type of pin fasteners being hard to remove and insert. What are the "easy" and "difficult" fastener implementations that we should seek out or avoid?
3. For regular or rollover boxes with lever actuated scarifiers, how do you adjust the digging depth of the scarifiers? Only by 3ph position control? Or can the height of the individual scarifiers be adjusted up and down on the scarifier bar?
4. For hydraulic scarifiers, must all the scarifiers always extend and retract at the same time, or can you extend just some?
5. Re hydraulic scarifiers, if the hydraulics malfunction (hose leak, broken cylinder, etc.) is there a backup method to manually extend and retract the scarifiers? If not, does that mean the opportunity to resell a hydraulic scarifier box is limited to people with remote hydraulics?
6. Is draft control at all useful when using scarifiers, manual or hydraulic?
7. Regular boxblades seem to have the scarifiers positioned on the end of the box closest to the tractor, so the scrape blades are all behind the scarifiers. Rollover boxes seem to have the scarifiers on the end of the box furthest away from the tractor, so the blade and box are all in front of the scarifiers. Is having the scarifiers at the front or at the back of the box better, or worse, or it depends? In what situations?
