Stalling B2410

Nik · Jun 14, 2004

I need your collective expertise. Hooked my B2410 HST to a 4 ft WOODS brushbull rotary cutter this evening. I drove the tractor out of the barn with the cutter about 50 feet to a field of 3 foot grass. Ran smooth. Engaged the PTO at low speed and advanced to rated RPM. After about 25 feet of cutting in low range the tractor started lugging, losing power and ultimately stalling. I disengaged the PTO. Checked all fluid levels and radiater filter. All were normal. Started the tractor again without a problem. It ran fine. However when I engaged the rotary cutter the same thing happenned after going 20 to 30 feet. I restarted the tractor easily and drove back to the barn. The 3 point hitch would lift the cutter as usual. I checked to make sure the parking brake was off and it was. My thought is that the PTO shaft may not be turning easily and placing too much load to the tractor. I checked the oil level in the cutter gearbox. It seems very low. When I unscrew the side drain some thick yellowish oil comes out so it isn't completely empty. This rotary cutter does have a slipclutch but I could not hear it slipping during operation. The cutter is about 2 years old and barn kept. As it is now dark I did not want to disconnect the cutter from the tractor. My small barn has no lights. The tractor had been run this weekend with a finish mowerand worked well. The fuel tank is at least half fuel. What should I check or do next? Thanks for your help.

Asked my wife if the tractor stalled when finish mowing this weekend. She recalls one time that the engine lugged slighltly 3/4 through her mowing. Perhaps I could have some water in the diesel fuel causing the B2410 to stall. I did refuel it with diesel prior to her mowing as the tank was almost empty. Does this make sense? How do I check for water? Look at the fuel bowl?

HOW DO YOU FUEL YOUR TRACTOR---CANS OR PUMP????
YOU MAY HAVE WATER IN THE TANK ,THIS WILL MAKE ONE LOOSE POWER AND STALL, BUT SOME TIMES WITH WHITE SMOKE AND ROUGH RUNNING WITH LOW RPM'S EVEN WITH THROTTLE WIDE OPEN. IF ENGINE SLOWLY DROPS RPM'S FROM A HIGH THROTTLE SETTING UNDER LOAD AND THEN RE-CRANKS EASY--YOU MAY HAVE TRASH IN A FUEL LINE ON THE SUCTION SIDE OF FUEL PUMP.....OR FILTER.... /forums/images/graemlins/smirk.gif

Did you try cutting the grass with the mower raised so that you are not cutting all 3 feet at once?

It may just be too much of a load for the tractor/mower to handle... my 1700 & 5 ft rotary mower will bog down in really tall, thick, coastal bermuda (such as grows on the back side of my pond's dam) if I try to cut more than 10-12" in height at a time.

It gets even worse if the blades are dull... When was the last time the blades on your rotary cutter were shapened?

Fuel filter replacement time??

Have you checked the gearbox to see if it gets hot??

Will it bog down with cutter engaged and at proper RPM if you do not cut any grass or take a very small swipe?

Have you looked underneath the mower yet to see if there's anything that might cause an unusual load? The one time my B2710 seemed to be losing power while mowing a pasture, I found that I had run over a rope and it was wrapped up pretty well under there. And my brother did the same thing, but ran over baling wire and got it wrapped up underneath.

Sounds like clogged filter. At full throttle it will create a vaccum in the line between injection pump and filter. Letting it sit lets the vaccum draw more fluid through.

Only will happen at full throttle under load. Your accelerator set the governor speed but under load the injection pump increases the amount of fuel delivered.

I've had it happen when trying to drive on the highway at full speed, it will cut out, then run, end up having to reduce speed and drive slow until replacing the filter.

Hogan, typing in all CAPS is YELLING and you may consider taking the CAPS LOCK off.
Thanks

Sounds like you may have been creating too large of a load for your tractor. Many times when bushogging, the cut material will build up under the deck at first until it reaches a certain amount, then it starts exiting the back of the mower. This could cause the symptoms you are describing because the load at first is less and gradually increases. Or you could just have been going too fast.

Just a thought. You can check this by raising the hog and seeing if you have grass build up.

Sounds as if it just being overloaded. A steady diet of 3' high Bermuda is pretty tough on a big tractor, never mind a little one. I had to return to the barn to tighten up the slip clutch on a 7' heavy duty Servis pulled by a 75 hp tractor this past weekend when I was cutting 3' high Coastal. Sometimes it's difficult to see a slip clutch slipping until it starts to smoke ... then you know.

I think if you slow down, use the low range and cut a little higher on the first pass, you'll be OK. After that you can probably speed up again but you may have to reduce the cutting width to 3' or so to stop overloading it and lugging down.

Like Bird said, check the deck to make make sure you don't have any "foreign matter" rapped round the blades or stump jumper.
