Webb Electric
Good Afternoon all,
New here so saying hello but also -
I have an old Webb Battery mower. The 2 speed setting has gone wrong. It is on full all the time. Have disconnected the switch and but not made any difference. Any ideas please?
Have had the mower for about 30 years and it was secondhand then................................
regards,
John

2-speed Webb
Can you come up with a model number?
Dim and distant memory says that they had a 3-brush motor and the speed change was achieved by some sort of change over from 2 to three and visa versa (vici verci round here!)
Is your switch (or switches) down by the motor and operated by a bowden cable from the handle bars or is ir a toggle switch mounted at the top of the handles?
Atco used to get round the problem by using a special battery with 3 terminals - common , 9 volts and 12!
2 speeds!
Thanks for the interest.
The switch is at the top between the handles. Disconnecting the wires and also joining them together makes no difference. there are just 2 wires.
Cant see a model or serial number - where should I look????
Regards,

It would have had either a stick on or riveted on ID plate with a number such as 296 or 297 .
I've got several parts lists and manuals showing 2-speed battery machines with the change over switch up by the handle bars but they are not at all informative when it comes to how this is achieved. Guess is that the switch either by passes a resistor or brings in a third brush in the motor - but it is just a guess!

Success!! Took the motor off and stripped it down (well took it apart) The wire from switch seems to bring in an extra magnet/coil - I'm not an electrician - and it was broken inside the casing. Joined it together and with much difficulty put all back (how ARE you meant to put the end in place and keep the brushes in place too???) and it works again.
The motor is a Standard Electric on the plate.
Many thanks for the suggestions.

Holding brushes!
Know what you mean, you need four hands! Stout paper clips bent to shape , split pins bent and shortened on one leg , and even elastic bands. Some motors, particularly Briggs starter motors have cut outs in the brush holder/end cap through which you can poke your weapon of choice (four!), re fit the cap and withdraw the the clip/match stick, tooth pick or what ever. Remember seeing an idea in the Service Tips section of a Briggs Service Update leaflet where someone had made four little clips using sections of a broken starter recoil spring!i

Hello John
I don't know anything about this mower, but maybe the electrickery. Please can you describe the switch - how many wires leave it? Do any of them go to what looks like windings on the motor or do they go to a resistor? Can you take any photos? Does it run slow if you remove (and insulate) a wire from the switch?
