Nasty Little Hydrostatic Transmission Secrets...

How well does your tc 35 handle a 6' cutter? I have a 1920 and was thinking of getting a 6' cutter.

Any difficulties in thick / tall stuff?

Hi Soundguy,

HA! I wish I knew! I got the 6 footer in Oct, and the grass wasn't very tall when I made the last cut of the season. Actually, that last cut was optional, and more or less to try out the new tractor and brush hog.

There's only dead grass and soggy ground right now. However, 2 more weeks of warm dry weather will make the grass and weeds shoot up waist high. I'll let you know in 2-4 weeks. If not, remind me!

It appears all the Class III drive ratios are the same. The final drive parts differences seem to all be related to the bull gears and axle shafts on the 40 and 45. The differential shafts are the same, so it is unlikely the final drive ratios are different. The axle shafts and related parts are probably bigger. The ring and pinion differences are harder to pin down, but appear NOT to be model related. This from a quick review of parts and service info this AM.

Someone needs to contact the Nebraska Tractor Test Laboratory and find out if they have tested any of these compact tractors. What we need is a TC 45 gear and TC 45 hydro tested at Nebraska that would answer all questions.

Thanks, Rick. I appreciate your help and inside knowledge. I truly don't consider this a big issue despite my over-dramatic sounding title to this thread. I just think it's a curiousity. I'm still very happy to have that extra lift capability my tractor offers and also the knowledge that I will probably never lug my engine down while pulling. I've only killed the engine once since I've owned the tractor. /forums/images/graemlins/grin.gif

Wall, I saw a list once and none of the New Holland Boomers were on it. I think Nebraska only tests tractors of 20 hp or more that are considered "agricultural" tractors. These CUTs may not fit that niche. /forums/images/graemlins/confused.gif

Soundguy,

I have a 6' rhino cutter for my TC40D and it does great. I've cut acres of 5' tall stuff mixed with 1-3" trees. Chopped it all down just fine. Of course, you do have to go a bit slower at times /forums/images/graemlins/smile.gif

Hmm.. anyone out there with a 1920 and a 6' mower? I know the tc 40 is close.. but it is maybee a tad bigger.

I originally had the 5' mower for my 8n and NAA.. but when cutting on the 1920.. I just feel that it isn't 'working' hard.. and that a 6' would cut down on my 4 hour mowing time a bit.

Boy.. now how to 'sell' the wife on getting another mower after only a couple years... might as well buy a sleeping bag for the barn while I'm at it.

( Brad, when I go light on the throttle I am not getting all the horse power to the wheels unless I put my foot into it. )

George,

By light on the pedal, I meant the hydro pedal. Running wide open throttle with only pushing the hydro pedal down 1/4 of the way or even less, that should be the most power. Most of the time mine will spin, but under good traction conditions, even just touching the pedal will not spin the tires, indicating to me the relief valve as kicked in. It does not lug the engine much during this slipping. At that point if I push the pedal all the way down, of course it lugs down and eventually stalls. But that is the same as taking a geared machine to its limit in low gear, and when it doesn't go, shifting to a higher gear and dumping the clutch. Again, it's going to stall.

I would be interested to hear what happens on your machine if you try just lightly touching the hydro pedal in low range, forward or reverse, under heavy load such as a steep hill where you usually can lug or stall. It won't go fast, but I'll bet it goes. I've never stopped my wheels pulling a heavy load. The only time was pushing into an immovable object such as a pile of frozen snow.
