Foward Reverse is backwards

/ Foward Reverse is backwards #21  
Go to your local dealer and have him look up service bulletin #SB95-06. It's even labeled, appropriately enough, "Tractor moves opposite to the direction of the HST pedal". It describes how the retaining pin for the swash plate in the hydro can break and cause the symptoms you're describing, and it means splitting the tractor to remove the HST. An experienced tech should be able to do the job with 5-7 hours and less than $50 worth of parts. Hope this helps....

That sounds exactly correct. It has been in the shop since Monday. They said they could have someone look at it Thursday morning. Now I wish I would have split it in my garage!

You might also want to consider seals and relief valves internal to the HST unit itself. A schematic I saw showed 6 relief valves inside the unit. There is also a charge pump which maintains pressure to the actual HST variable pump & motor system. When the charge pump ran backwards, the suction action on what is normally the pressure side, may have pulled part a relief valve or sucked in a seal. This would prevent the charge pump from maintaining pressure in the HST casing and may be part of the reason for the tractor only moving a few feet before bogging down.

Hope this comment helps.

I don't think my previous post conveyed my appreciation for your help. I don't offically own this tractor yet as I am swapping my uncle for 2 landcruisers. If it had broke down AFTER the swap, I don't think I could afford to run it over to the dealership. Its nice to know that I have a great fountain of info to draw from!

Thanks again,
Brandon

BTW, Sound Tractor cracked into it today so I should be able to confirm your diagnosis by next week. While it was in the shop I got some tractor time in an L series, full cab and FEL, AWESOME TRACTOR!

Pity you couldn't get 3 landcruisers for him. /w3tcompact/icons/laugh.gif Sorry, I couldn't resist.

Most of us here have found TBN to be a tremendous resource. I certainly have.

I agree. Three cheers to TBN.

Get ready to spend about 2000 dollars on the hst. That is what it cost me last summer to have the hst repaired on my b7200hst. There is a company in calif. that rebuilds the hst. He wanted about 1100 for rebuild. I do not the name of the place but the phone # is 909-784-8423.

Kudos to Snell, he nailed it.

Sound tractor reports that the B7100 had a retaining pin that was too short. The mechanics said the pin was sheared. All they can do in put in the longer pin. Now I have to wait a week for the gaskets to come in, and I might have my first tractor!

Thanks again!

Not to argue with your dad, but I wouldn't buy a tractor unless it had 4WD. Had an old International B 414 and while it was a great tractor the 2WD issue presented itself many times.... Just a thought......
 
/ Foward Reverse is backwards #31  
I have one neighbor who has 5 tractors; 2 being used, bigger farm tractors of course, and who says he'd never buy a 4WD, waste of money. Of course, he's never owned or used a 4WD, and a few years ago, he did pay $100 to a fellow with a 4WD Deere to come pull him out when he got stuck./w3tcompact/icons/laugh.gif

Bird - My dad's neighbor, who also see no need for 4wd, had to have one of his mid-size JDs pulled out by a wrecker a couple years ago. If Dad had found out before he got it out, I'd have gladly made the 2 hour drive to try to pull him out with the Kubota. /w3tcompact/icons/laugh.gif

He's the same one who said my L3600GST wouldn't till the soil around Dad's place. Then, the HST wouldn't because "they don't have any power". Then, it wouldn't pull the tiller after I added the scarifiers to it because it was "too small" and didn't have "gears". So it would have absolutely thrilled me to get the chance to tug his tractor out of the mud. I don't know if it would've done it or not, but it would've bothered him a lot more if it had than it would've bothered me if it hadn't. /w3tcompact/icons/wink.gif

He's another one of those "experts without knowlege". Not to say that he's dumb - he isn't. He's got a lot of knowledge about a lot of things, because he has a lot of experience with a lot of things. But he is also the victim of a very common problem: he doesn't know what he doesn't know.

<font color=blue>he doesn't know what he doesn't know.</font color=blue>

I think we're all in that particular boat. However, I know that I don't know what I don't know. The problem you may be describing is that he doesn't know that he doesn't know what he doesn't know?

I'm not being weird here, although it may sound a bit like it... It's just that no one can know what they don't know; it's just that some people can't quite figure that out, and I think that's what you're describing here...

GlueGuy - <font color=blue>It's just that no one can know what they don't know; it's just that some people can't quite figure that out, and I think that's what you're describing here... </font color=blue>

The phrase "don't know what they don't know" was a pet expression of mine when I was in the corporate world. Usually, it was part of a longer statement, such as "I don't have a problem with someone not knowing something - what bothers me is when they don't know what they don't know." That perhaps makes it a little clearer that I was describing exactly what you said.

It's fine to not know something. There's lots of things I don't know and would like to, and that's one of the main reasons I'm here on TBN. But, when a person doesn't have the ability to realize, or won't admit, that he doesn't know something, all kinds of really stupid stuff happens. That's the main reason I jump in, sometimes a little too vigorously perhaps, whenever somebody says, in effect, "I've never used a thingamajigger, and only seen one once, but I sure don't think you need one or should have one." I want to say "Why, exactly? Because you don't have one, you don't want anyone else to? Is that it?" I want to say "Of course you don't know what they're good for - we knew that already - that's why you don't have one. You've got the whole thing completely backwards. There's no evidence that you don't have one because they're useless - the evidence points to the possibility that you don't have one because you don't know how useful they are. Don't you realize how stupid what you just said is? You just said you have no idea what you're talking about (you're doing fine so far...) but you've got an opinion that's just as good as everybody else's (logic train just got derailed...) and you think everybody else should act upon your completely baseless conclusions? (I'm not even going there...)" Not that I get worked up over it or anything... /w3tcompact/icons/smile.gif

On the other hand, the TBN archives are full of excellent discussions that started with a question like "I don't have a thingamajigger but I've seen one once, and I'm wondering what they're good for. Can someone tell me?" At that point, I love to see those that have one, have used one, have seen one used a lot, or whatever, to jump in there and explain all about it to the rest of us. And I'd like to see those who don't know have the ability to know they don't know and learn along with the rest of us that don't know. Or something like that. /w3tcompact/icons/wink.gif

MossRoad - Well, um, I, you know, uh, just, um, you know, uh, don't know. /w3tcompact/icons/smile.gif

Well, now I know that GlueGuy knows that he doesn't know what he doesn't know, but you never know if Mark knows what he doesn't know or if he knows what he knows as well as he thinks he knows. /w3tcompact/icons/laugh.gif

Harv - Please see my most recent prior post. /w3tcompact/icons/wink.gif

But, there's one thing I do know: I don't have a pink tractor!!! /w3tcompact/icons/laugh.gif

<font color=blue>I don't have a pink tractor!!!</font color=blue>

Not yet. But forces on conspiring to get you one. /w3tcompact/icons/wink.gif I'm renting Harv some paint, he's picking up another thing or two at Bird's on the way by, then some dark and not so stormy night, an unnamed EF5 will become enhanced in the color department.
