I bought a new BX2370 and tried out the belly mower yesterday. The grass was not overly tall, but it was time to mow. It did have some dead stuff on it from last week. Is it normal for it to bog down the engine? It was really noticeable it high range going flat out, however it would do it in low range a little bit also. On the average I would loose 500-700 rpm. Also when I started it had roughly 3/4 tank of fuel and in 3 hours it was empty? Another issue is if I would raise the deck and put it back down to mow another pass my height adjustment would change on me. Is that normal?

I would say - NO that is not normal at all, I have the exact same model and mine will kick out heavy grass without any moaning.

Cutting in high range would place more work on the engine, but depending on the type of grass, height of grass and rate of travel - that machine should do it very well. What height you cutting? Anything under the deck? Like some old twine, string that kinda stuff?

WHAT rpm you cutting in, what you describe should be cutting at 2500-3000 rpms - makes a hugggge difference on this machine where the throttle is placed. Blade was designed to cut at 2800-3000 rpms.

HAVE YOU GREASED the spindles on the deck???? I have found that from factory - the amount of grease in the spindles is not enough. AND it will take a good bit to fill 'em. SPIN them by hand - you should be able to turn all three blades without a lot of effort - feel for any type of "drag"

Was it empty on the gauge? OR was it empty b/c you filled it up? Gauges on those machines are almost useless. IF I sit just right - it will light up full then got down 4 bars on the gauge!

How many hours on machine? It is NOT brand new is it? Like - have you got your 50 hours in yet?

I forgot to mention this is a new machine. I am running the throttle wide open and the deck is set at 2-1/2 inch.

When was the last time you changed BOTH fuel filters were changed? The BX series have been known to not be entirely accurate fuel gauge reading wise. And you could have a weak fuel pump or a supply issue i.e. pluged or restricted fuel source.

The little details!:mad:

Call your dealer up and tell them whats going on! As said above not normal.

What speed are you mowing at and what are the conditions, wet up hill when this happens?

It is a fairly flat area. Some minor hills. It happened in low range full.rpm just a little bit and in high range flat out hauling.

Ck the blades to make sure they are not installed upside down. Easy to do. The guy on the assembly line may have been his first day.

My 2370 spits the grass out pretty good and doesn't bog the motor down whe in heavy grass but I mow at 3 or 3 1/4. As far as the cutting height changing mine has been back to the dealer twice in the 4 months I have owned it for that reason. The first time they changed the thing that has the steps in it. They said the otiginal one hadn't been machined correctly. The new one lasted about a month and it started doing it again. They came and got it and this time they said it was wore out already. The new one they put in they hardened it hoping that might help. Mowed twice with the hardened one and it hasn't moved yet. Time will tell though if it will stay that way.

When you say flat out hauling in high range do you mean full speed? With the hst pedal all the way down? If so you are going WAY to fast as far as ground speed! Keep the engine RPM's up and SLOW the ground speed.

When your deck changes position, does the knob also turn as the deck drops (meaning can you see the change in deck height by looking at the knob)?

Does that hardened part have a "new" part number? Or did Kubota change/upgrade the part and keep the same number (if they didn't change the p/n how do you know if your getting the hardened one or not)?

Also - is the part that is being replaced the "CAM" (P/n K2581-4410) which is on the end of the shaft where your turn the knob to set the height? I can't tell from the parts diagram how this piece works, but I assume there are notches in the cam and some sort of spring loaded (or spring steel) piece rides against the cam and drops into the notches as the cam is rotated.

Yes the knob moves. You can watch it move as you are lowering the deck. The hardened one is not from Kubota. The dealer hardened the part himself with a torch. The piece they change has steps in it for the different cutting heights. The first one they put in lasted about 20 hours before it was wore out.

I have a new b2601 which is quite similar engine and had no trouble cutting tall grass in medium right off the truck. I was running with the throttle set at the pro mark.

Ok. The dealer told me that the height adjustment is actually just a gauge wheel to get you close since the mower deck is floating and what is going on is when I have it set at 2 or 2-1/2 that I could actually be mowing at less than that causing the deck to want to dig in which causes the tractor to bogg down and that I need to mow at a setting of 3 or more. That makes since to me except I can't see or hear it dig in. Can someone explain to me what he means by this? When I set the adjustment to at least 3 it is fine and doesn't bogg down. I'm just trying to understand how this works and why it has to be at 3 or above. The gauge wheel let's you go lower?

You have to set the gauge wheels for the height you are cutting. The manual for your mower will tell how to do that and where to set them for the height. If the gauge wheels are all the way up and you are trying to mow at 2" then you probably are digging in with the mower.
