Snow Hydrostatic and Compact Plus / Minus

[CDN24]

Mine is a NH TZ25DA, 3cyl diesel 25 HP engine, 18 HP at the PTO. Reverse in High is practically useless powerwise, I can't back it up my trailer ramp in High. In Reverse Low it's "boil me an egg' slow. I'm looking to get a snow blower attachment for it; the front mount ones so far are costing at $8500.00 ... mounting kit etc, and the rear PTO one is around $2500.00; + tx. Besides a stiff neck after 2hrs of snow work I'm afraid the rear mount at 350lbs will stop the tractor dead in it's tracks facing a good grade and 5" of wet snow. If anyone has experience with blowers on these small units I'd like an opinion. Tx.

On my TC, I adjusted the speed for reverse by screwing the stop nut further in. It did help quite a bit. Worth a try anyway.

Do you have snow chains?

 

[oldnslo]

Can you drive up slopes going forward in high that you can't back up? If yes then possibly the reverse relief valve in the HST is set to low. It should have similar torque going both directions.

 

[jenkinsph]

I agree with oldnslo, check the relief valve settings.


One of the few small tractors I tried before buying my x749 mower was a TX24DA or TZ25DA not sure which one. I found I preferred the single range in the Deere for most mowing and raking chores. I felt the two range choices were mismatched for most uses. Otherwise it was a nice machine IIRC.

Hi motownbrowne, top nut eh, my TC is smaller but hmm top nut I'll check that out for sure, thanks. Oh, firewood eh, what kind of splitter do you use? I seen some videos of screw splitters off of the PTO and it looked like the best kept secret. And maple syrup too; way out of my league, ...... good on you.

Hi jeff9366 Snow chains; have 'em never installed 'em, no regrets yet; agricultural tires and loaded. I do some spinning; no denying that; maybe next year; I bought the cheaper option of the 2 available to me, not inspiring to look at and then there this phobea I have of them busting off and flailing like 'Wild Thing'... my fel bailed me out many times.

Hi oldnslo, I haven't done a direct comparison but I will do that. But I think I'm safe to say quite a difference in the two. You guys put me onto something here; I've been putting up with this for years, mentioned it to the dealer serviceman and the reply was basically ... safety issues. I interpreted this as being little tractors like this in the hands of ? 'unacustomed' could be dangerous especially in reverse so they make them that way. An adjustment was never mentioned and that's what I was looking for then. I'm on the hunt now.

 

[oldnslo]

CDN24,
Possible the reverse was set lower for safety concerns. I know frequently the reverse speed is slower than forward. Also not familiar with your transmission so I don't have a clue on where these valves are or how they are adjusted. Most of these smaller HST use shims.

good luck and please let us know if you find a solution.

I spoke to the dealer the mechanic actually and he's used the same machine. This tractor should be as strong in reverse as in forward and if it's that slow there may be obstruction keeping the pedal from bottoming out; that pretty much matches your stop nut comment. That's on my to do list; the price is right. The good news is this tractor can handle a 54" rear mount snow blower.

 

[CDN24]

I'm liking motownbrowne's ..... 'adjusting a stop nut' and the dealer's suggestion of obstruction preventing full pedal travel. It's strong enough in reverse so speed according to the dealer mechanic should only be pedal travel .... swash plate opening yada yada / HST. As far as adjustments on valves goes I went through the shop manual looking for an adjustment, also asked the dealer mechanic, I think you're right no quick adjustment available.

I can't comment on the HST speed adjustments, but I will say that while snow blowing you will need to go very (very) slow, particularly with an 18hp machine. On my previous Kubota L3410 (28hp pto) and a 6' rear blower as soon as I started pushing snow while going uphill I would lose traction. Leaving the blower slightly off the ground helped with uphill traction, then lowered to the pavement downhill. The weight of the blower on my rears really helped. I don't want chains because I plow / blow 15 or so driveways and can't risk the damage to the pavement.
There were 2 driveways I was not able to get up after the NE blizzard of 2016 (35"), but these were the kind of driveways that you know are going to be a problem... Plus they waited until 3 days after to call me when the snow was getting pretty wet.
The difference between 5" and 35" is not quite as linear as one would think. The blower will need time to process even 5" of snow, and when you start pushing it the tractor will likely lose traction, particularly uphill.
About rear mounts and comfort, I never had an issue with looking backwards even for hours at a time. What I did finally realize is that blowing snow with an open station tractor is miserable work no matter how much attention you pay to the wind! Even in my area of relatively mild winters I recently decided to get a cab tractor.
Anyway.... you didn't ask about cabs. You will want the "boil me an egg" slow reverse gear!

I love my cab and only have used it twice now with the AC on.

Forgot to add, I decided on power shuttle rather then hydro. It also opened up more options and it was cheaper.
