Question about Black & Decker 19" Electric Lawnhog Mulching Mower with Rear Bag

4 Answers

It just stopped

I was mowing along on Saturday and the mower just stopped. I removed the cover thinking the motor had blown, it did not smell as if it had blown. I replaced the switch in the handle and that did not help. I'm wondering if there is a fuse on this machine. Any Thoughts?

    I had been mowing with the catch bag on for about 45 minutes. I changed the cord to another outlet to finish. It started initially ( went one 4 foot push into moist grass) and then stopped. I checked all electrical fuses in house, switched outlets again etc.....

    solution? I waited a day and sure enough it started just fine? I am calling Black & Decker to see if this is a known problem or an unadvertised "overheat or mositure" protect mechanism

    I had been mowing with MM875 Black and Decker 19 inch electric lawn mower, and it stopped about 30 mit. later in the middle of cutting. The grass was very long and wet (it was about 11 AM in a cloudy day) and the engine was constally conking, and I was forcefully pushing the lawn mower. I tried next day, but it still did not work. I opened the handle, and I did not see the burn marks on the wire. How do you check if the motor is OK or not?

Mine stops like described above... but after I go to garage and dirnk 1/2 beer while watching NASCAR, then go back and mower works great.... but only for a few minutes on hot days.  Results in lots of beer consumed, but great NASCAR covereage.  On cooler days, it stops less often, but still stops.  Results in less beer consumed, but I haven't a clue who won the Busch series today.
I thnk it's a temperature thing... but not sure about that.  Sometimes works great, even on hot days; but not worth a crap on cold days.  Go figure.
OTHERWISE, I love my cordless electric mower.... I just with I could mow the whole damn lawn without interuption.

Most (or all) electric motors have an overload device (heater) that detects high current in the copper windings of the motor. so if the motor is getting too hot, a thin piece of metal bends and breaks the circuit. after a while the thin piece of metal cools down, reconnects the circuit and it will start again until it overheats. overworking your motor will cause high current in the copper windings and hence the motor to stop working until it cools down.

Solution? replacing the heater in the motor may do the trick. that thin piece of metal can only bend so many times before it gets weak and/or faulty.

i am having a similar problem. i took off the cover, but it looks like the heater is internal on the 19" cm1000 motor. i'm not brave enough to tear open the motor itself..=(

good luck.

I had a similar problem. My solution turned out to be the key. The metal part of the key was no longer lined up properly (I think I turned it too hard once). I took a pliers and set it correctly again, and have not a problem since.

This most often happens when you are mowing too much grass at once, or when the deck (or chute if you have a bagger) is clogging for some reason. Sometimes this is made worse by having dull blades. Usually mowing at a slower speed or mowing more frequently will help solve this. If the motor is struggling with the blades, these are usually the culprits. Clean your deck thoroughly, cut the lawn more often, or cut it slower.

In some cases, if your PTO belt may be worn, stretched, or need adjustment. When this happens, the motor will not slow down with the blades but will keep running normally and you may smell a burning rubber smell as the blades slow down.

When pulling cord to start mower there was a click sound and the cord would not rewind

Remove top cover to your engine with all other attachments. Be careful because loosening this part will most likely recoil the cord. The recoil is in the top of the cover. Turn cover over and put some oil on all the mechanical parts at center of unit. Pull the cord till your satisfied it has been lubricated.
Replace top cover along with all attachments, and you should be ready to mow. GOOD LUCK.

LTX1000 42" 18HP Kohler - Blowing fuse after 2-4 min mowing.

sounds as though you are on the right track
but be sure to check the wiring directly from the electric clutch on the front of the motor back to the switch
a wire could be pinched in the frame and shorting out intermittingly
look around and find those wires and move them around and look for chaffing and tightness
and what you could also do is to unhook the clutch at the connection to it at the front of the motor and engage switch and ride around and see if fuse blows and if not you may have an electric clutch issue
