BX engine almost stalls..

[Rusty4242]

I am just getting used to operation my recently acquired BX23( 90 hours on it when I bought it from a local dealer) Unfortunately, I got no manuals with it, so I'm sort of winging it. It seems to be in great shape. I was using the bucket to push some thickets down a bank when the engine almost stalled upon reversing up the bank a few times. It finally stalled. I restarted it,raised the bucket, put it back in low, reved it up,stepped on the diff lock and was able to back up the bank. The BX has a hydro tranny. I have been digging stumps on level ground with nary a problem. What do you think? Thanks, Rusty

I think you may not have been running the engine fast enough.

Is there an operating manual there, or just parts book?

How steep was the bank and were you in low the entire time. If you weren't running at a high enough RPm it is understandable that the BX would stall, also if you were mistakenly in high gear and tried to back up a steep high the engine may bog and then eventually stall.

I don't think so and my apology. I was not thinking parts vs operations. I posted this without regards to your needs. I'll keep looking.

The key is to keep the transmision in "low" on steep inclines.

Thanks, I might not have been reved up enough. Although I was in low, for sure.
The bank was about 25 or 30 degrees I'd guess, and kind of soft.

Hmmm, might help to put your seatbelt on. There is a kill-switch under the seat that stops the engine if you don't put weight on the seat while driving, especially while going backwards up a hill.

Tractor thinks it has lost it's driver and stops. Safety stuff...

I have had many problems with that one and I'm not the one who miss out on any meals!

Unless you are on the road in transport, I'd leave it in low all the time. Also, I almost ALWAYS go full thottle when working the BX. I back it off JUST a tad for mowing on the flat.

Go to the dealer and have him order you manuals. There is stuff in there you need. If this is your first tractor, BE CAREFULL. Get the manual and read it. It is not a Craftsman riding mower, and there is stuff there that can break your body.

I believe that was irresponsible for the dealer to give you that machine without manuals. Dangerous for both you and the tractor.

If you can't get them from your dealer, call Kubota and/or throw a post out and find a local member who will let you photo copy his manuals.

Also check the fuel level when you are working the tractor on slopes. If you let the tank get too low, that can cause you problems when the fuel starts to slosh around and the pick up starts to suck air. I never let mine get below 1/2 tank, unless I am starting the day with the full tank, and by the end of the day it is close to empty. Dusty

I don't know how familiar you are with Hydros. Remember, the pedal is not an accelerator like a car. It is a gear shift. The more you push it, the higher gear you are in. If the tractor engine is starting to bog, let up on the pedal some. Even though I knew better, when I first got my Hydro I did just the wrong thing and pressed down on the pedal. After years of driving, it is what is ingrained in my brain!

Brian, that's a really important point. The HST pedal is NOT a gas throttle. I have operated several HST's on my hillside... and I keep forgetting about that too. Your post is a great reminder for both seasoned and new operators alike.

It was the seat switch. Duh. It should have dawned on me at the time.I was sliding forward. I will hound the dealer for that BX23 manual.
Thanks,Rusty

Rusty - - glad you found the culprit.

lp333 - - why have you owned a BX22, 23, & 24? Are the upgrades/changes from model to model that significant?

r0GuE - - guess everyone's situation is unique, but I almost never run near full rpm, except when mowing, & even then I'm a step or two below max. I am careful to stay above 'lugging rpm'. Also, I seldom use low range - - just when I need the extra umph. I may be abusing my BX, but in the 4+ years & just under 900 hours I've owned this great machine, this is what's worked for me.

I have the rear mount bagger, which runs off the rear PTO. At full throttle, or very near full throttle, the system functions flawlessly. Excellent cut, good vacuum, nice lawn. If I had to guess, I'd say that the combo I am running is about as hard as you can work a BX. Two powered large powered implements. Sure there are bursts of hard work with a blade or loader (I do that too), but an hour on the lawn is a lot of action for a BX.

When I didn't have the bagger, I backed it off a small amount. But I think it is important to have the blades spinning fast to get a good cut. And when mowing once a week, the grass can get pretty high.
