Just ordered a new NH TN55

TN55,

Hey, it's Monday morning... it's not too late to call the dealer and cancel that TN55.../w3tcompact/icons/smile.gif

I agree with Jimt. For a couple dollars more, I'd get the TN65 {I missed it in your post}, or really go for the TN70... even without SS.

A few more PTO hp does make a vast difference in brushhogging. You're not talking about mowing your lawn here... Besides the few dollars more you spend now will be forgotten in short order. This is a purchase that will more than likely outlast your lifetime and possibly the kids...

Really, go down to the dealer's today and give them another going over...Surely the dealer will have more of an incentive to move something on his lot with something he already owns.../w3tcompact/icons/smile.gif

TN55:

I agree with the turbo arguement, used it myself....The TN65 is not a turbo machine. For $500 more you won't be sorry. I personally have 33 acres that I take care of (brush hog and driveway maint.) and help take care of my in-laws 50+ acre farm. If all you plan on doing is brush hogging you'll be ok. That is how my in-laws started and in a few short years they now plant/harvest about 8 different crops each year. Most of their 50 acres that is not wooded is tilled or in alfalfa/hay. My father in-law had a 3430 (42 HP, same as TN55) which he/we used for several years. When he bought it he figured it was all he ever needed. It did not take long for him to change his mind and he now has a 4630 (56 HP Turbo 4x4) because the 3430 was not enough tractor. It cost him ~$13k to make the change (includes the $3k hit he took on the trade vs. new cost) That is about $1000/HP. Right now you can buy HP @ $100/HP and you'll never regret it. Ever think about why your dealer has TN65's and TN70's and no TN55's?

Were abouts in upstate NY are you. I got my NH2120 in Champlain NY. Love the 2120, tough little unit, but really love to get my hand on a TN65 with a cab!

Hi Derek,

I'm in East Greenbush, NY... just outside Albany...from the ridge I can see all those "skyscrapers" {let's count um...1,2, 3!} that Harv & Bird like./w3tcompact/icons/smile.gif

Isn't there a auction up in your neck of the woods this weekend?

Derek, don't you think the TN65 prices here are unbelievable? That will be a huge jump for you, from 2120 to TN65...Wow!/w3tcompact/icons/blush.gif

The prices are pretty wild. Maybe another record snow fall next year and then the year after that I could get one. Those cabs are nice. Is quite a jump in size. Would get rid of the 2120, get the TN series and a smaller unit like TC21. Beep, Beep, Beep... My alarm clock just went off!! back to real life, I have a 2120 it does a great job.

There is one this weekend (Fairfax)and another next weekend (Swanton). I'm most likely go to the one next weekend.

TN55 - What tractor did you end up with? Are you happy with your purchase?

tn55 · May 21, 2001

I am still waiting on it to get here! I called the NH dealer and he said that he hopes to have it in by this coming Friday. I have my fingers crossed. I am in desperate need of a tractor because my pastures are starting to get BIG! He said that he would send me a loaner until it comes in. I will post a picture when it arrives.

Tn55,

What is the big deal about the turbo?

I have about 90 acres and I am considering the tn70 or tn75.
I drove a tn65 and was very impressed, I just worry that its not enough tractor for my needs.

Also I noticed that all these tractors have the same basic engine. Some just have a turbo and the compression ratios are different for each model.
However, if you look at the new holland web page it specs a compression ratio of 18:1 for the TN70 (http://www.newholland.com/na/Products/tn70_specs.html) and 16.5:1 for the TN75 (http://www.newholland.com/na/Products/tn75_specs.html).
This seems backwards, would not the higher compression ratio yield great hp and torque? I wonder if the web page has the ratios backward for the TN70 and TN75.

Does anyone have any information on the realtive relaibility and repair cost for these different uints?

Phred:

There are no issues with the turbo...The only think that you should do is let the tractor idle for several minutes before shutting it down after a hard run. This is to let the exhaust temperatures drop and cool the turbo housing so the oil in the turbo bearings does not coke. You should also let the tractor idle for 10-15 seconds when first starting to make sure oil pressure has reached the turbo bearings. Don't know why people are afraid of the turbo, think about how many millions of Powerstrokes and Cummins engines are out there in pick-ups...How many turbo problems do you hear about. (Other than the bolts falling out of the Powerstrokes housing, which is a design problem in my opinion). I have the TN65 and it is a great tractor, just wish it had a little more power (Although it has never not been able to do what I asked of it). If I was doing it all over again, I would buy the TN70 for sure.

As far as repairs, 130 hours and 1 year old, $0 (so far). When it comes time for an overhaul, you'll see a little more cost due to the turbo-rebuild. But that is at ~4000 hours or more? That is a lifetime for most part time farmers.

Fred,

I believe that compression ratios are computed. Piston moves over this volume and compresses into this volume. That does not reflect that the turbo can pump more than ambient air pressure into the cylinder. So you can think of the cylinder already being under pressure before the compression stroke even starts. It makes sense to lower the compression ratio (computed) to reflect this extra air. In the end I expect the measured overall cylinder pressure to be the same or possibly higher for the turbo.
