Finally got to use this for the first 50 hr service on my Kubota MX4900. It worked great! The only oil that was lost was out of the oil filter which is expected. By using this there was no gush of oil coming out where you had to rush to get another filter on. It allows you the ability to wipe the sealing surface off so you know there is no contaminates that can cause a leak. Also no mess with oil over shooting the drain pan.
I feel the vacuum pressure is just right where it holds the fluid in but not enough to damage seals or suck the oil out.

Changed Hydro oil on NH WM25s and didn't loose much of fluid when swapping transmission filter but the lower hydro suction filter was still pouring substantial amount of fluid so had to quicky screw new one on.. about 1QT of oil lost during the job.

The design of the flexible adapter connection to the pump is crap. Slight bump or twist and it would separate from suction pump. There is not enough locking twist to keep it without falling out. The vacuum pump came with couple adapters but you can't use them in tight place at least not in my situation. Also the charring port and button cover design is useless. It will not stay on and needs to be taped into unit. For the price this is being charged it should been designed better.

OK

I have a LS MT774, I bought this the not have to replace the fluid when changing the hydrolic filters. Yes I have 2 to replace both easy to get to underneath but the first change at 50 hrs, you got to use a cheater bar to break them loose. The 1st one is a big one so I got a 2 inch wide stap wrench, even that I had to put sand paper under the strap to break it free. With all this stuff to do i got the first one off and started on the 2nd just as I was about to Crack the seal the Vac Trac shut off , yep 30 mins had gone by. So I didn't get to loosen that filter until I had a full charge on the vac. 2hrs later I take it off and that one leaked more than the first but still not a gush of fluid, just a few streams. The second was for the power shuttle. But wish the run time was an hr. Maybe the second change will be easier, faster since they won't be factory torque. Also the power shuttle filter is towards the far end of the vac so makes sense more fluid loss.
The first one the big one, I only lost what came out of the filter

Looks to be well built product but the first thing I notice is the flawed charging port cover. Has to be a better way. Doesn’t stay on at all and it comes taped on.
