NH Boomer 3050
I was reading an old forum post at http://www.tractorbynet.com/forums/new-holland-owning-operating/298842-new-3050-cvt-update-8.html and noticed that hydraulic cavitation was mentioned. So I thought I would mention one of the many problems I have had with my Boomer 3050.

When I bought it brand new, I noticed that it had a strange intermittent noise that came from the bottom of the steering column. If I raised the engine RPM to 1,500 and then brought it down to low idle, there was a delay of approximately 15 seconds before the intermittent noise starts again, I found.

I mentioned this to the NH Service Manager and when he had the tractor in for repair for another issue, he called it hydraulic cavitation. Hydraulic cavitation is certainly NOT good! Well, it had been making the noise since I bought it and they were supposed to check it over thoroughly, before delivery but they failed in many ways. So at around 50 hours it was finally fixed by replacing all three external filters on the right rear of the tractor. Apparently NH was aware of the problem, I found out. See the attached document. The part numbers for the new filters are: (1) 47755594 (Inline strainer filter) (2) 47825344 (Canister).

Have any others had this problem?

WCarp, were these instructions "not" in your owners manual? are the instructions different?

WCarp, (1) 47755594 inline strainer filter has been discontinued. Replaced by pn 1-32-575-303 . This information is from Messick's website. Maybe this fixes the cavitation.

The document is not part of the Service or Owner's Manuals but is like a Technical Service Bulletin. This new setup stopped the hydraulic cavitation.

I see that the auto notify of a response is off by default, so otherwise I would have responded sooner.

Was just looking at an ad for a used 3050 cab with just over 300 hours on the clock. Guess I should ask if all these filters have been replaced. How do you like the tractor?

Well, I like the tractor in many ways but in some ways I don't. I definitely didn't want a certain other brand because of engine survivability and the trouble was, there was no other dealer close by and my previous tractor was a NH TC-45D which burned up in a fire, so I tried to find an equivalent tractor. It was difficult to find an equivalent tractor so I ended up getting the Boomer 3050.

Now for some of what I like and don't. It was a new tractor but had a few hours on it and it was in a another State so I didn't get a good look at it before purchasing it and there was a time issue. I asked the dealer in Quincy, WA to look it over carefully so when they brought it, there wouldn't be any issues. Well, there was many issues---as if whoever checked it over was blind! Since the tractor you're looking at has approximately 300 hours on it, all of the initial problems should have been caught and eliminated.

Anyway, I do like the styling, the cab and the ability to quickly get at many of the engine components. All you have to do is lift the hood. But when you get down to servicing the tractor, it can be challenging to do what should be simple things like change the engine oil and fuel filters if the NH loader is on it. I like the CVT transmission in that it is more efficient than an hydrostat so you get more power to the wheels, I suppose like a gear transmission. It does take some getting used to. It's set up to run the engine at a fairly high RPM when moving, I suppose to give it maximum power but you don't need all that power at low speeds and just moving the tractor from one place to another. Mine has the Enhanced User Interface which includes a Anti-Stall switch, three speeds instead of two, password protect the parental Lock menu, and what is called Cruise Preset. I haven't done much with the cruise control yet. When I have been doing some loader work pushing hard against rocky ground, the tractor at times hasn't stopped immediately when I take my foot off the Go Pedal. If I remember right, switching the Response switch to Fast helped. The tractor has a speed limiter on it which limits the speed for a few minutes when the transmission is cold. I looked in the manual for this but it's buried somewhere. Also, there has been an update on the transmission disconnect mechanism for towing where it changed after serial number 0121. The NH document is titled CB2521_TransmissionReleaseMechanism.pdf.

One of the many problems I had was that the hydraulic pressure was too low (300 lbs.) so I couldn't lift nearly as much as I should have been able to, the battery was sulfated and had to be replaced but the battery on the tractor is actually smaller than it should be for the engine size so I shoehorned a larger battery in and now it starts in colder weather like it should. Because it has a cab, which is nice, it adds to the needed weight to push better and haul things in the bucket safely. The rear tires are oversized for the amount of weight on the rear without a backhoe so even at a pressure lower than NH recommends the tires tend to wear in the middle of the tread so I lowered the pressure and had a Titan Field Tech come out and look at the problem. He said that you can go down to 10 lbs. okay in the rear tires but the absolute minimum is 6 lbs. I also have a liquid biodegradable ballast in the rear tires so the tractor supposedly weighs around 7,000 lbs.

On mine, the exhaust pipe was placed directly against one of the two oil cooler lines to and from the transmission, negating the cooling effect, which wasn't good so I shimmed it out a ways. There are two fill plugs for the front axle so it needs to be on a level surface when you're checking and filling the front axle with oil. The engine oil capacity is approximately one quart less than the manual says! My tractor has Supersteer which gives a much tighter turn radius and is nice except if you do loader work or for some other reason you need to shift the tractor front end just slightly, it will shift the tractor to the left or right more than you may want. Sometimes, the side shifting can be advantageous. The loaders on a Supersteer tractor have a slightly longer reach. The clock in the instrument panel and the radio both run too slow. The instrument panel was replaced and the new one is only somewhat better. The old one lost approximately five minutes a month and the new one approximately four minutes. The Jensen radio clock loses approximately two minutes a month. The clock in my Ranger appears to be much more better.

Well, perhaps that's plenty for now.

I would like to add that to change the transmission calibration, the dealer has to connect their computer to a connector in the cab and after the instrument panel was replaced, the dealer had to connect their computer to the tractor to set something up right. So one issue is that for some work on the tractor, you have to have the dealer do it which is not nice for the user. :(
