Looking for others opinions

[teeravis1]

This past summer I bought a Kubota B3030SDC. I really like the tractor, it seems to have great power and everything seems to run smoothly, & it starts well in the cold. However, there are some things I noticed and was wondering what other B3030 owners thoughts were.

1-It seems the seat is tipped forward so you feel like you are always sliding off.
2-When shifting between High, Low, or Medium it seems like I have play with the lever quite a while wiggling it and hitting the brakes and Hydro pedal to get it to go into gear smoothly, this does seem to go away for the most part after the tractor has been running for a long time?
3-The tractor doesn't seem to be very good on any slight incline, it seems to have a high center of gravity. This is even with the bucket empty, I guess I thought it would be more stable on slight side hills. Is this just the Kubota or all small tractors?

For anyone reading this that is looking for a small tractor I don't want to steer you from the Kubota B3030, it is a truly great tractor. There are many more positives than these 3 minor things I mentioned. What I mentioned above are really minor issues in the big picture. When I bought this tractor I looked at Case/New Holland, Cub Cadet, Mahindra, John Deere, and as far as I am concerned in the 26 to 32 HP range Kubota is the way to go!

Thanks

I was just wondering if you had a ballast box or some kind of counter weight on you 3-point when you use your loader? This might help with stability

No, I did not have a ballast box, or anything hooked up on the 3 point, but your probably right. I would think that would lower the center of gravity.

Next time you need to go between ranges, try step down hard on the brakes. Let it come to a complete stop with your foot still applying the brakes. What you are effectively doing is helping to eliminate any loading on the gears. When I do this, I can easily shift between ranges.

I have yet to ever have a "hug the hill" attitude with anything but saddle type tractors. You learn what you can and cannot do with these high clearance (for their respective size) tractors. My least stable tractor I have ever owned was a Ford/NH 2120. My most stable was by far a International 454 2WD.

I drive a B2910, the prior model to the 3030 so I cannot answer question #1.

Question #2 - this is normal for every tractor I've driven and the current tractors I use (from Kubota and New Holland).

Question #3 - this is also normal for most tractors when they are in HIGH range and have an HST transmission. It could also be partially operator error as when a HST transmission is used, there is more torque supplied with less foot pressure on the pedal and less torque supplied with greater foot pressure. Consequently if you are pushing the HST pedal to the floor when your tractor is struggling to climb an incline then you are actually making it harder for the tractor to climb the incline. It is very counter-intuititve.

As for stability, loaded tires help.

Further operating the tractor without any ballast when using the loader is VERY dangerous. Please do not do that. Check your owners manual for proper ballast. It really is NEEDED.

I want to clarify here, I am not an evil kenevil on the tractor and try to drive on hills, but My house is on a hill so my back yard at the end has a good slight incline.

Sounds like my property.

But even on a very slight incline a HST tractor in HIGH range will not climb the hill, this is true for virtually every tractor model/brand with 3 range HST. Further, operator misuse, as I described above is a common issue.

With regards to using a loader on a tractor that does not have ballast, there is only one way to say this.

<start rant>

DO NOT DO IT. IT IS DANGEROUS. PLEASE DO NOT DO THIS, ESPECIALLY IF YOU HAVE A FAMILY THAT YOU WOULD LIKE TO STAY ALIVE TO SEE & SUPPORT. NOT EVEN ON PERFECTLY FLAT GROUND. It is simply that dangerous. Most tractors actually suggest BOTH wheel weights and a ballast box when using a loader. It is very easy to roll a tractor when using a loader, this is especially true for an unballasted tractor.

Many threads address the 'sucky' Kubota seats on the B7800, B2630 and B3030. I find my seat a little annoying also but I'm glad I have it, can sit in it and operate my machine. If there is a good replacement for it, I haven't found or heard about it yet.

Your Cab model 3030 will definetly have a higher COG than my B7800 or Robert's 2910 (same machine for all intents) in large part because of the Cab.

Mr. Skurka's advice is somehow correct. Even ballasted tractors with a full bucket are deceptively easy to roll. At an absolute minimum, please have your rear tires loaded.

Please try and remember that regarding the rough shifting, this class of tractor is about 75% unaided mechanical linkages. We do not have computerized transmissions or control systems in the B series machines. The transmission shifting mechanism itself is based on technology that was patented more than 80 years ago is my guess - so - some fiddling will be required. NOW that being said, if you cannot actually get it into one of the ranges, there could be a problem. Rocking the machine, clutching, braking, generally adjusting the position of the machine at rest may be required to engage another range.

There is nothing wrong with your tractor based on your description. Enjoy it - many would give more to have one!

I still don't get the whole torque thing. I would love someone to explain (in simply terms, I'm slow) how that works.

I couldn't agree more with the ballast. I have a little BX1500 that can only hold 400lbs in the bucket, however without ballast, the machine feels unstable. I ussually keep about 450lbs on the rear when working with the FEL on. It feels real solid then.

I'm not a mechanical engineer type either so I don't know exactly why it works the way it does.

BUT, what I can tell you is that a HST pedal is NOT like a car's accelerator pedal.

With a car you have a transmission that is constantly shifting to adjust to the torque demands (the car downshifts when going up a hill or if you need to accelerate). Further, the engines revolutions increase or decrease as needed based on the load created by a combination of the changing demand from both the transmission and the accelerator pedal.

With a tractor you lock the range selector into a range. For example you put it in HIGH range (notice it is a RANGE selector, the HST pedal is sort of like your gear selector). You set the throttle at the desired engine RPM, unless the engine is bogging down under extreme load, the engine RPMs will run at a constant rate regardless of the needs of the tractor. Once you have set the gear range and the RPMs, then your foot starts to press the HST pedal. At this point, the HST is sort of like the car's constantly varying transmission. When you barely push the pedal, it is sort of like being in 1st gear of a manual transmission car. . . not a lot of speed but plenty of pull to get you going. When you press all the way down on the HST pedal it is very similar to being in "overdrive" on a car's transmission, you can go a constant speed without much effort, but you can't climb a hill or pull a trailer in that gear. In effect 'overdrive' has very little torque. When you press down on the HST pedal so that it is "floored" then you have created a situation where you have very little torque, and that is fine for driving down the road but not for doing any work.

So think of a HST pedal as an infinitely adjustable torque selector or an infinitly adjustable gear selector within any given "Range" you have previously selected.
