Well I have finally had a chance to put a few hours on the new L35 and it is really a mixed bag.

I don't know that I'd be willing to give up that 4-bar 45 degree rollback loader. The backhoe is so much more than my "typical" one on my Ford 1710 (Ford 758 hoe same as JD "8" I think) I'd never want to go back to a low gpm hydraulic system either, which makes the steering, hoe and bucket work unbelievably fine. The engine is one torquey sob. No complaints there.

But I'm surprised that I'm not hearing about people getting KILLED on these things. Kubota, for whatever reason (factory people never have given me an answer) does not put an HST trans in these, instead going with their GST trans which for you old Kubota folks or JD/NH etc is a trans that has a straight line shifter, 1-8, no clutch ever needed, and a steering column mounted Forward-Reverse lever, again, no clutch needed.

Great idea huh? Well if you are on flat ground I find it an acceptable tractor. Now that I've been buzzing around on our BX2200 I am beginning to see the benefits of HST though.

I feel this tractor should have a declaration on the cover of the brochure...NOT FOR USE ON ANY SLOPES, no matter how slight!

I had the tractor on a slope, nothing like the maximum I've ever been on, in fact I would call it minor compared to a lot of driveways I've seen. No load in the bucket. Hand throttle at idle. Went to downshift and the g**d***ed thing almost got away from me. Shifting up you're never in a situation where you don't want to go faster, but shifting down you normally want to go SLOWER! The thing went into limbo for what seemed like an internity and FREEWHEELED. If I hadn't had a lot of room I would have gone off a cliff, killed someone, who knows. The GST is touted as a clutchless system (i.e.simple) yes it is, but you better have your foot shoving on the stop pedal if you use that shifter on any downward slope.

What do I do?...STAND ON THE BRAKES. Fortunately I had left them locked together. The tractor SLOWED down, not anything like the panic stop I can do in my Ford 1710, and when I got it stopped, or almost stopped I realized I couldn't hold it with the brake pedal no matter how hard I pushed on the pedal. (I'm 240lbs so I've got plenty of belly-ballast!/w3tcompact/icons/wink.gif)

I have tried this on other slopes even less, and it takes a TREMENDOUS effort to get this sob to hold still. I think this must be the situation with all new Kubotas because this is just a glorified L3410 with a super hydraulic pump and bellypan to tie the loader and hoe together.

The owners manual does state that the transmission will not hold the tractor with the engine off, and this happens with the HST as well, but not as fast. With my BX if I put it in gear and turn the engine off it will roll down a hill like a normal stick shift car put in 4th gear. The L35 will wait a second or two and then LET GO and freewheel.

The big problem with this? The manual says use the parking brake. WHAT A friggin' joke! The first day I had this I moved it a few feet and noticed a red light on the dash was on. Oops, parking brake. I just assumed it was the high torque engine overpowering the brakes. Well it was but not due to extra good engine! Later when I need to use the brakes to turn the tractor it didn't seem to make any difference if I was doing it or not.

On my "antiquated" Ford 1710, 1300 hours, when I am using the turning brakes, I usually pump them off on off on, everytime I hit them, with LITTLE FOOT PRESSURE, I can visually see the loader bucket jerk over an inch or two. I feel the turnbrake benefit on this L35 is completely ABSENT!

So what this tractor is is a flatlander's special. Utility companies seem to love them but they must not go down any slopes with them.

At least with the HST the engine at idle would allow the tractor to stop. If this had brakes it would be OK but this scared the you know what out of me. If I was on a slope and for some reason had to get off the tractor how would I do it? If I can't hold the tractor by standing on the brake pedal I guess I could set the parking brake and step off while it is creeping down the hill.

If you're on the tractor there is no way I can see other than digging in the ground with the bucket as a brake. Or maybe I should put spikes downward out of the outriggers on the hoe!

I really wanted to stay with a manufacturers designed product i.e. hoe and loader, but I don't know if the risk is worth it. There are lot of places on one of my pieces of property I'd NEVER take this. Maybe I'll have to hang onto the old Ford after all.

Or maybe I could rent a JD or NH? I haven't checked their brakes. I used one of these on flat land before purchase, never in my wildest dreams did I expect this to have such piss-poor brakes and a transmission that also can't be used to hold the tractor. To hell with worrying about the North Koreans launching a missle at us, I'd be more fearful if I looked up and saw a Kubota sitting on a slope above me.

Maybe Kubota will put the HST in the L35 and I can have my cake and eat it too. I could live with the crappy brakes if I had the HST. Or maybe I'll have to bail and go the L4610 and Bradco route or JD 4600 or the NH equivalent.

Love the Loader, Love the Backhoe, Love the Engine, Love the Hydraulics.

Everything else is about as useful as a soup sandwiche.

Brakeless in Seattle.

del, I've never driven a GST tractor, but have you talked to your dealer about those brakes. Brakes like that are just hard to believe, and I would sure think something is just defective and needs fixing.

Bird, the thing is brand new, if the brakes are defective, what does that say about Kubota?

ps to all...didn't want to start a negative thread I usually always post with a bunch of wise ass /w3tcompact/icons/wink.gif comments that are meant to lighten people's days, I just felt this is something that should be said. Could be worse....at least it didn't come with Firestone ATX's on it!

Are You serious??? The L35 is the most stable tractor I have ever driven. I have had the thing sideways on slopes, so that if I didnt have my seatbelt on I would fall out of the seat. I didnt even seem to be pushing it to the limit. And If your talking about staright up and down slopes I suggest you have the thing checked... My L35 grabs right away when downshifting on slopes.

del, I certainly know how frustrating it is to buy a brand new product only to find a defect the first time you use it, but it happens occasionally to every manufacturer, so I don't get too upset if they correct it or replace it and it doesn't happen too frequently.

Yes I was referring to downslope, if I'd been sideways on the hill it wouldn't have been able to suddenly freewheel. And it does engage (probably like it should) it's just that I don't have the stomach for suddenly being in neutral I guess. And the brakes do "work" the tractor will slow down, I was just expecting the brakes to be at least what the brakes are on my 17 year old tractor, especially since you are expected to use the parking brake as your only way of holding tractor on a hill. It's nice though to hear the tractor is stable sideways on a slope, maybe I can just start crossing the slopes that way /w3tcompact/icons/wink.gif.

del,

I agree with Bird, call the dealer and have it checked out! We enjoy you posts too much and don't believe there is a link between here and tractor heaven! /w3tcompact/icons/laugh.gif

I never have had the opportunity to try out an L35 but my Kubota is a regular gear tranny and the brakes would throw you out of the seat if you dont have the seatbelt on and panic mash the brakes on a downslope. I would think there is a problem with the one you have possibly only a minor thing like only need adjusted properly??? I had a good mental picture from your post ( del ) and imagine you had a serious crease in the middle of the tractor seat cover ! get it checked out soonest!
Seems like I saw another post about brakes on a Kubota not working very well and the author reported it was corrected by adjustment by the dealer??

I would think if it was an adjustment problem the pedal would not have enough travel, the pedal feels hard. More like faded brakes after a long down hill run in a car. The only time I had hard brakes and (no braking) in a new vehicle was a Ford Pickup. Turns out the axle seals leaked on to the shoes from day one. Now I always look at the backing plates on my cars to see if they are "dark". Kubota's not that easy, actually didn't one of the posters mention these are actually IN oil!

I could see one wheel having a problem, but since they're independent of each other seems unlikely. If I hit the turning brakes on my Ford (and I do this only at part throttle) I can actually lock one wheel and turn the tractor around if I want with the one wheel stationery. I don't think I could do it on this Kubota unless I start pumping iron! And no, my tractor seat isn't scrunched up, but my steering wheel has custom fit, perfect fit finger grips in it now!

And again guys, I'm not talking about some steep slope you'd be nuts to park anything on.

On a related (hey humorous) related topic, I had a friend who once worked at a cemetary. They used Case 580s (2WD) for their (a hum) duties. One of the other workers would take a shovel, put it on the sloped road, get going in the 580 and then hit shovel with one of the back tires and jam that turning brake on, the tractor would go straight making all kinds of sparks from the shovel.

Don't we all need employees like that?!!!!

I hit the brakes hard in my Ford once without the brakes locked. I "knew" it before, but that statement in the manual about keeping them locked together at anything above SLOW speed really sunk in. Actually I had gotten lazy and just bridged the pedals with my foot, but in haste to stop only hit one, wow that baby TURNS QUICK! Lucky I wasn't calling a neighbor to help me right the thing (or worse)

Cheers!

Del- I use the L35's baby brother, B21, and don't think my brakes are any better than yours. With HST on the B21 it has not been a problem and the thing turns so well that I never felt the need for turning brakes. I did have one of my mental farts one day and shift ranges on a slope which left me freewheeling and looking for more brake than I could find. That will not happen again! I bought my tractor used and figured that my brakes were just the way they were. After hearing some of you talk about the power of your brakes I think I will get mine checked out.

Do most of you have brakes that will "stop on a dime" or "slow you down"? With my hills, I don't think mine will stop on a hill if it is free wheeling with any momentum. Sorry, I don't think I will try a field test.
