In the background you are looking at a Dr. Power Lawn & Leaf Vac....and yes the Hydraulic Dump is to replace it. For leaf season coming up the leaves are up against a 6-foot mower deck, hooked up up to a 5hp power pack blower that you empty from the seat of the tractor!! Don't get me wrong, Dr. leaf hooked up to a JD430 with 60mmm is very good but this thing is just sick! It's like cheating. Needless to say, the good Dr. is currently for sale at a local dealer. As far as the dumping the Dr. Leaf vac all you do is remove the rear panel and pull a lever, it tilts back....and then have a pitch fork handy to help remove the 315 gallons of 10:1 shredded leaves and grass clippings. To empty the hyd. dump all you do is backup to where you want to empty, pull back on the scv lever and watch the container go up like a BFI dumpster truck. The container flips over the top, gravity empties it from close to 7ft., you then push the scv lever forward until the container stops back down into position and you drive away never having to leave the seat of the tractor

The unit is custom converted to i-match because that Hydraulic Dump system is designed around a standard cat.1 3pt hitch, not an i-match. A tech that I know came over and had to weld a couple of brackets on the hyd. dump frame to make the hook up to the i-match hitch possible. I did this because I ordered the optional bushing kit for my ballast box and I did not want to have to take the i-match off to switch between two if I don't have to.
If you research on John Deere, you will find that the 72 mower and the hydraulic dump are not compatible with each other due to JD not making a boot to fit a 72mmm.
The hydraulic dump is not i-match compatible
The hydraulic dump is not available on 2520 as deere makes it seem as the 2520 is too small a compact to be able to use that unit on.
