Your new Kubota tractor has a few things that you'll want to check on daily. These are the water levels and the engine oil. If you're mowing, also check that there isn't any buildup on the blade such as flower petals, grass and other small bits of your crop residue such as insects and the like.    

Keep an eye on your water temperature as you're mowing and working with the tractor as well. Water temperature is your ideal guide to ensure that you're not overworking your Kubota or plugging up the radiator.

Newer models of Kubota tractors have an air cleaner vacuum sensor that is designed to change color if the filter is plugging up. This is a great way to keep an eye on your filter's life span. The dustier the conditions the more often you're going to have to change this filter. There are also filters that have a dirt collector that when you squeeze the end of the container you can dump out the dirt. The dealer will most likely show you how this is done and walk you through the steps.

Keep in mind that the gearing and the ground speed will help you to factor in your maximum torque, your engine performance, and your fuel efficiency. Newer Kubota models usually run at about 2500 RPM when they are at maximum torque.

During the mowing procedure, you'll want to run your Kubota at a speed that is just slow enough to properly cut the weeds or crop that you're mowing down. This will ensure that your task is done in a timely manner without overdoing the speed. It's typically about 3 MPH. If the exhaust is black you may be overworking your tractor.

You want to ensure that you're properly running your tractor and not overdoing it. The only time you should have to use the 4X4 is when you're requiring traction, pulling discs or chisels.

You'll want to get into the habit of doing a daily checklist on your tractor. Your daily checklist should include the following:

1. Check all of your fluid levels including:

Engine oil, coolant, your fuel, hydraulic fluids, and any other fluids. Also, be sure that you check underneath of the tractor for any puddles, leaks or fluids that may have accumulated.

2. Check your tires and wheels

Are your tires and wheels properly inflated? Be sure to check with your owners manual and keep them at the recommended pressure. Watch for any cuts or breaks in the tires or tread. Check and ensure that all lug nuts are tight and secure.

3. Check the batteries

Make sure that they're securely anchored to the unit. Are the connections clean and fully functional? Is the electrolyte levels are accurate.

4. General Condition of your Kubota

Ensure that there aren't any cracked or broken parts. Check hoses for damage or leaks. Are the shields all in their proper places? Watch for any loose parts, loose bolts or loose nuts. The SMH emblem should also be in place and clean. Clean any grease or mud off of your tractor as well.

Once you've sat down in the seat you'll want to check the seatbelt to ensure that it is fully functioning. After you start the engine check the oil pressure and ensure that the pressure is steady and at the right level.

Check your flashers and lights and walk around the unit to ensure that all of the flashers and the lights are properly working.

Here are the checkpoints you need to be checking:

Questions from our clients

Q: How do you prime a manual transmission pump on a Kubota Tractor L305?

A: The easiest way to do so is to let the hydraulic pump prime itself


Q: What can be done to help with water pump failure in the L3710?

We only had 134 hours on a motor during the 2005 annual cleanup and we noticed a problem. There was the sweet smell that typically meant antifreeze and a green tint when I smelled my finger after wiping it across the area. It wasn't really wet, there was just a trace residue left in the area where antifreeze dried after leaking on the front of the water pump housing. Is this normal for the engine? The V Belt was removed from the water pump and there didn't seem to be any extra play in the pump shaft. In fact, it felt quite normal. Also, there was never really a problem with the temperature, it seemed to hold steady and we never had it run hot.

Have you ever had this problem on this Kubota tractor?

A: You have a drive train warranty that should be good for three years. If the tractor is only two years old, it is best to take it to the dealer to have the tractor checked before the warranty runs out.


Q: what is the smallest Kubota tractor used for landscaping?

I've been considering purchasing a tractor to use for a variety of reasons with landscaping. Not only do I want a backhoe, I would also like a loader as well and it would be nice to run a number of three-point tools. One of those tools would ultimately be a Harley rake. At some point or another, it will be necessary to get into a tall sided one-ton dump.

What would be the best unit for this type of all-around performance and to handle those three purposes? Some of the models I have been looking into include the L3830, B7800, and the B21. I'm a little concerned about choosing anything smaller and the B21 may not have sufficient horsepower to run a Harley rake but I think it would be a great tool to have available.

It is not out of the question to choose another brand if there was a quality option that was right for my needs. The smallest unit would be preferable because of using it in a residential area for maneuverability and it would be easier to transport as well.

A: If you really want something that is good for your all-around needs, you should look into the BX-23. If you can fit something in the bucket, you will be able to lift it. It may be necessary to have a bigger tractor for extremely heavy loads or moving pallets but when it comes to the power for the size, we are quite impressed. The Harley rake and TR-3 rake are available for this type of tractor and it also is equipped with a backhoe that is supposed to dig about 6 feet but it really does about 4.5. Good luck choosing the right one for your needs but this is the one we recommend


Q: Problems with your Kubota Tractor?

Do you own a Kubota tractor or do you work around one? I was curious about the most common problems that are experienced with these types of tractors, either big or small.

A:  If you maintain it properly on a schedule, you shouldn't have any problem.


Q: Plug in a fuel filter on a Kubota tractor?

My 3750 Kubota tractor has a tankful of B-50. I am happy with the way that runs right out of the shop but we had a cold snap recently and the fuel filter stalled the engine when it plugged up. It looks like there is some type of reverse river gunk in the filter but it doesn't have any grit. Is this something that has happened to others? If I continue to burn more tanks of bio, is it going to disappear?

A: It is going to disappear when the tractor warms up. You will be fine using more bio but it may need for you to adjust it a little bit lighter to get it to run properly.


Q: I'm looking into a 30 hp Kubota diesel tractor/loader. Is this a reliable choice?

A: When it comes to reputation for longevity and quality, you can't beat what this tractor has to offer. When you get right down to it, however, there are always hundreds of parts that make up the individual machine. Machines are going to wear out over time and some parts are going to have more problems than others. The amount of wear of this type of machine could be measured with an hour meter that records how much time you have been using the machine. If it were a truck or car, the odometer would tell you the number of miles that have gone by.

The question is, how many hours have you use the tractor and what is the year that it was manufactured? Both of these things can affect the value of the tractor when you go to get a fair price for it and it is also going to affect the appearance. When you take a look at the appearance, it will often indicate the way that the tractor was cared for and treated by the owner. Some people are going to be quite meticulous when it comes to changing filters and oil on a schedule. Others will ignore it and don't do any type of regular repairs.

If your tractor is missing parts, or if it has the wrong parts on it or they have worn out, you're going to have a number of expensive problems. Some of these issues can be quite problematic. Buying such a tractor would only be beneficial if you paid a very low price for it and repairing what is necessary can be costly if the former owner did not do it. You can go to a local Kubota dealer and they will let you know the fair market value but if you really want to know the tractor itself, they would need to see it and the hour meter.

It is also important to check the hour meter and make sure that it is working and is original. These tractors are extremely reliable and this isn't typically an issue. The real issue is not the tractor but rather, it is the seller and you need to believe what they have to say. When you find somebody local that has this experience to look after the machine, you can reward them for their efforts. People like to know what they are looking for and when they listen to their intuition, it is typically the best choice.

Question: What Are The Various Weights Of Kubota Tractors?

I am new to farming and am considering purchasing a Kubota tractor. This will be my first tractor so I have a few questions. I will be using the tractor to work an 80-acre farm and perform tasks such as moving hay, mowing, light clearing and some dirt work. I'm looking at the Kubota M7040 but I'm not sure if this tractor is heavy enough to do this type of work. I've looked at several different brands of tractors and the salespeople are continually pointing out how light the Kubota is when compared with other tractors on the market.

Exactly how many different weights are there in Kubota tractors and how are they used? Does the Kubota line have heavy duty tractors designed for moving large hay bales and doing digging and trenching?  Are there lighter tractors that are better for the type of work I plan on doing?

Also, what type attachments are available for the variously sized tractors? It would be handy to be able to change out an attachment and be able to start a new task without having to purchase a new tractor. I would be interested in purchasing a few attachments to go with the Kubota M7040. Is it possible to use some of these attachments interchangeably between Kubota tractors of different sizes?

Is it such a big deal if the Kubota is a bit lighter than other brands of similar size? What about maneuverability? Does the lighter Kubota operate easier and have more maneuverability because it is lighter? For the work I'm planning on doing with the Kubota M7040, will this tractor be big enough?

Answer: There are several attachments for Kubota tractors and many can be used on different models. The Kubota M7040 is a medium-weight tractor and is perfect for the types of farm chores you are describing. You can purchase a front mounted blow or blade to move dirt, level gravel roads or clear snow. You can also use a rear mounted PTO driven blower to clear roads and hay areas. The smaller Kubota tractors usually can't handle a front mounted blower because their hydraulic flow won't support that type of attachment.


Question: Where is the hydraulic fluid refill on a Kubota tractor?

I need to add hydraulic fluid to my Kubota BX22 tractor, but I can't locate the right place to pour in the fluid. Where is the hydraulic fluid reservoir located and does it have a separate fill cap? There is no manual for this little tractor since I inherited it. Please help!  Thanks!

Answer: In older Kubotas the hydraulic fluid was added near the rear of the tractor. There was a small plug close to the 3-point hitch, right in the middle of the rear. It can be hard to see the plug because it can get covered with dirt and debris. That's the first place I'd look. If it's not there, check the transmission. There is sometimes a filler cap located on top of the transmission near the oil dipstick.



We have a Kubota tractor. The last time we drove it, the front left tire fell off just a few minutes after starting the tractor. Is it possible to put it back on and if so, how do we do that? Also, what is this tractor's typical top speed?

Update: Evidently this is a tubeless tire. Also, the lugnuts are on too tight and we can't get them off.

Answer: You'll have to remove the tractor wheel and take off the old tire. If it's tubeless, you may be able to patch it and put it back on. Try oiling the lugnuts to see if they'll loosen up.

As for speed, these tractors will usually reach full speed at about 20 mph. They need to be able to move heavy equipment or pick up and move large round bales. You'll also need some speed if you're going to use the tractor for cultivating, cutting hay, plowing or tilling. When you are working with the tractor, such as plowing new ground, you may not be able to get more than 2 or 3 mph because of the resistance. These tractors are also very powerful and use very low gear ratios to increase their power. Their giant wheels and tires are designed to allow the tractor to move through the wet ground without getting stuck or sinking.


Question: Which model of Kubota tractors can take a LA853 loader?

A: Kubota L4330 will work with that attachment. This is one of the L-series Kubotas and is probably the smallest that will work with a LA853.

Question: I'm looking at a Kubota L175 with 775 hours and turf tires. It appears to be in pretty good shape and runs well. What's a fair price?

Answer: This is a nice little tractor. You can look it up on the Kubota site. We do know it's a reliable tractor. We sell Kubota parts and know this is a long-lasting tractor.

Just as a little info, the L175 has a two-cylinder, 17 hp engine. There is no water pump and it cools the engine with air circulation. It is important to ensure the radiator stays clean, especially when it's operating. If the radiator does get too hot, there is a whistle that will blow a warning. When this happens, immediately shut down the engine and let it cool.


Question: My Kubota is sucking air

MY tractor recently got stuck and I had to use the loader to back it out. Now, there's a sucking air sound coming from the hydraulic fittings box. Could it be a loose fitting? Is it possible to tighten this?

Answer: Did you check for fluid on the ground? We would recommend you check your fluid level. Also, check your filters and your hydraulics air breather.


Question: Should I buy a Kubota Tractor?

I am trying to decide between a Kubota bx25, a Kubota b2620 and a John Deer 2320. I need a small tractor with good power. I also want a backhoe attachment. What's your recommendation?

A: We would go with the bigger tractor, especially if you're going to use it to dig or bush hog. These may all be a bit underpowered, but they are all good tractors.
