AHVFB / AHVFC Hydra vac

[Timj]

Mounted the AHVFB Hydra vac on the 4118 today to get started on leaf clean up.

Removed the 3pt and installed the mounting plate

Mounted the deck baffle and boot in the AHRM48 deck.

Mounted the vac onto the tractor. On the AH tractors the return hydraulic hose from the deck must have the quick coupler turned 180° and attached to the vac and the return hydraulic hose from the vac is attached to the tractor. Then the case drain must be hooked up.

Connect the suction hoses and your ready to go.

The only difference between the AHVFB and the AHVFC is the AHVFB has the bracket for the bagger attachment.

Good instructions Tim!

Good instructions Tim!

Hope they help someone someday and help build the site.

Tim,

What is the white thing on the bottom RH side of you tower? Thanks for posting the pictures!

We all love seeing this Case equipment in use and learn from others. I appreciate every post!

Sharp eye Bill, I tried to keep it out of the picture. it is a gallon plastic oil jug.
I should start a new thread but I can hijack my own thread.
Last fall when I was really digging into the poor performance issues of my AHRM48 and 4118 Gator (rip) and Brian H had brought up the possibility of the relief valve dumping off oil as a possibility. To rule it out, I disconnected the discharge line from the relief valve that connects to the inlet of the hydraulic pump. I plugged the pump side and ran a piece of hose from the relief valve to that jug to see if any oil was getting past the relief. Not a drop has.
I've been waiting till I change the hydraulic oil and filter this fall to put things back the way they belong. Then I only have to drain the system once.

I can't even imagine pulling my 3pt off in order to put the hydravac on. Could an adapter be built to mount the hydravac to the 3pt arms?

Something along these lines: 3pt arms in blue, the existing frame-to-hydravac mount in red, 3pt-to-hydravac adapter in black:

You'd need a special/short toplink.

But I'd have to do SOMETHING.

The HH34 only has 4 bolts and the 2 hydraulic hoses to remove, the vac bracket uses the same 4 bolts. It only takes a few minutes to swap.

I have seen a few mounted to the 3pt. There may have been a kit or option at one time. Otherwise I seen a few nice fab jobs by other Case Ingersoll nuts. A selector valve would be needed.

I modified one to fit a 448 with 3 point. The vac is heavy enough that front weights are required when hanging on three point. I will try to post pictures of it tomorrow..
