Dangerous Kubotas...(long)

[PaulB]

Art - were you referring to del or me in your post? Do you think my 1700 is braking properly (3 months left on warrantee!), in that it will stop the tractor easily on the flat, but will not hold it still on any sort of a slope.

 

[art]

Paul for you to have had your tractor roll down the hill something wasn't working. With hydro's often times the brakes aren't used often enough and they get oxidation on the linkage. With Del's problem there were two potential problems. One when ever you go over a step hill you should down shift before you go over the edge. On another post I noticed some one who shifted two gears at once asking the transmission to do a double shift while expecting the tractor to hold him back? I don't think so! There is a gap on glideshifts between 4th and 5th where it shifts the range and speed sections at the same time. Just a simple question to ask you when does the hydralics put out the most at a idle? Bad time to be shifting, think if the transmission was low on oil and you went over the hill and there was no oil to reach the pump?

Del I can relate to the lapse between gears being the nature of the beast but the brakes on the other hand....I think that goes without saying!

I live and work on overall very flat ground So I can't say I've run into that same problem but I do believe that either your brakes are not seated in or glazed, linkage hanging I would also say to also check for freeplay but you've already done that. Call the dealer and see he has to say on this issue as well.

Brakes to me are just that brakes not slowers so to speak.

PaulB & Others,

I don't have long slopes but I have some short slopes that are steep enough to make me slide forward in the seat when going down them. On my NH TC18, when going down, if I take my foot off the hydro pedal it will almost stop, creeps so slow you can barely see the tires turning. With the brakes on and locked down with the parking lock, I at over 200 lbs. can rock forward and backward and not move it anywhere. On one longer slope, I got going, put it in neutral, free wheeled shortly and the brakes slammed me to a stop. This is how my TC works, don't know if it's right or wrong, but I like it because it stops when I want it to.

If I'm booking along in high range and take my foot off the hydro it will stop fast, like I've heard most describe with hydros, but like I said, the hydro when you take your foot off will almost hold it on a slope, the brakes lock it down!

JimBinMI, how can you slide forward in the seat if you have your seat belt on and your foot on the brake pedal?/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif

Bird, it ought to stop, it weighs 10% of the L35 (well maybe a tad more) /w3tcompact/icons/laugh.gif

My riding lawnmower must really be a killer. I looked all over and couldn't even find a brake pedal.

 

[JimBinMI]

Bird,

They call it "gravity"! /w3tcompact/icons/smile.gif
I was on a part of my lawn where I regularly mow that has a slope and I wasn't wearing my seatbelt! /w3tcompact/icons/shocked.gif

Wen,

Regarding your usual sarcastic response, it seems as though brakes ought to be designed for the unit they are made for...so brakes for an L35 should probably be stronger than those for a NH TC18 and both should work properly for the unit they are designed for, if they don't then I'd get it in to the dealer. If it only slows down the unit it should be called "slower downers" instead of brakes! /w3tcompact/icons/wink.gif

Regarding your riding lawnmower, is there a clutch that when depressed all the way becomes a brake? If not, never saw a rider without brakes, maybe you could use it for a wheel weight on that M of yours.

[W5FL]

I thought it was a technically accurate response. I will try your suggestion. Maybe it does have a brake on the clutch pedal. Never saw a manual with the tractor. You are just too sensitive...those kids must be really getting on your nerves now that school has started.

Naah, it is not heavy enough for a wheel weight, and besides, all the oil would drain out. /w3tcompact/icons/smile.gif

My M6800 is actually a little heavier than the L35, and the brakes on it are teriffic.

My last tractor (Massey) had brakes that were just a little worse than dragging your foot. [shock]

 

[Bird]

That's what I was guessing, JimBinMI. I thought you wore your seat belt./w3tcompact/icons/shocked.gif And I thought you were back in school working and wouldn't have time for tractor talk during the day./w3tcompact/icons/smile.gif But, yes, the brakes and HST on my Kubotas work like yours do.

[paccorti]

I'm curious. I guess tractor brakes do not have a vacuum assist like a car?

 

[JimBinMI]

Bird,

I'm back to work next week Tuesday, students start Aug. 28.
We had some friends move to Ft. Worth area and their kids already started school. We won't get out until June 13! /w3tcompact/icons/frown.gif

[Bird]

paccorti, a separate thread on tractor brakes might be interesting because I don't know a lot about them myself. I know that my own (B2710), and a lot of others are strictly mechanical wet brakes, work well, and work the same whether the engine is running or not. And of course the park brake uses the same components, i.e., simply locks the pedal down. A diesel engine does not provide the same vacuum that a gasoline engine does, so as far as I know you generally do not have anything vacuum operated unless you have a separate vacuum pump. I used an old Oliver 1755 baling hay quite a bit and really don't know how the brake system works on it, but I do know that it had good brakes with the engine running, not as good with the engine off; similar to cars with power brakes. They worked, but took a lot more pedal pressure and the pedal did not travel as far down. Maybe someone else can explain how that system works; hydraulic boost perhaps?

Yep, JimBinMI, I think all the schools in this part of the country are back in session. Maybe my memory's just not so good, but I seem to recall us going back to school right after Labor Day when I was a kid. Seems to me they sure start early nowadays.

Bird

 

[JimBinMI]

Bird,

Michigan wanted to mandate legislatively that schools couldn't start until after Labor Day, but they didn't have enough support. What they did do is mandate that you can't have school the Friday before Labor Day so it would create a 4 day weekend to boost Travel and Tourism dollars in the state! If we did start after Labor Day, with current days required to be in school, we wouldn't get out until third week of June! /w3tcompact/icons/frown.gif

Del - I read your message with great interest. I'm just catching up on almost a month's worth of forum messages - a daunting task - after being very ill from heat stroke. More on that in another post later, but though there's more here than I have time and energy to comment on, I'd like to say one thing: My L4310 should have brakes very similar to your L35's mechanically, and they will slide my non-stock high-traction heavily ballasted radials on my gravel drive. I think yours should, too, so I'd transport it (not under its own power) on down to the nearest dealer for some under-warranty service.

Mark

 

[Bird]

Mark, I started a couple of times to post a message asking if anyone knew what happened to you, but then I thought maybe you were just on vacation (some vacation, huh?). Sorry to hear you were ill. Hope all's well now. Welcome back.

Bird

 

[gordon]

Ditto to what Bird said. Missed your wit and knowledge!!! Glad to see you back and hope that your feeling better. Now you need those fans that I told you about!!!

Mine do too, but holding the tractor from going backwards down a hill is a completely different kettle of fish...
