The Great Big Lawnmower Thread

If there are only three terminals then it does matter. One will have the connection to the coil that closes the switch so if its the wrong way around it won't work. Don't think you will do any damage if you get it wrong provided you don't short out the batter.

Thanks. The most important for me is to make sure which of the big ones is input/output/doesn't matter. I already knew about spade connector (+) and base (-) and that these open/close the circuit - this is obvious, however large terminals not.

Hi all.

I've a 2001 Countax D1850 with a faulty Warner 5219103 electric PTO clutch. Monster mower.

I might be able to buy a new replacement clutch for £423.14 + import duty from www.gardentractorspares.co.uk if the 2008 model is a match - waiting on reply.

Countax has closed down so contacted Warner USA to buy clutch directly for < $200 but it's OEM and still restricted. No go.

Does anybody out there have any experience with this clutch or matching OEM part to an item on the Warner list ?

I can match the physical dimension but no idea on the rated torque or if the mount is CW \ CCW etc. ID is 1.25".

Any help - I know it's very specific - gratefully accepted.

Thanks. PW.

Thanks Deezell.

But the ID is too small on that one.

I rechecked the ID and it's 1.125" (28.575mm) shaft + pulley OD 6.375" (161.925mm) + 12VDC 10" lead.

I'll start the engine tomorrow and see if the shaft turns CW or CCW.

This one self-dismantled and stayed spinning under the lawnmower for 30 seconds…😁

Here is a picture of all the parts to the clutch \ brake unit. It might help someone else understand a similar problem.

The six clutch \ pulley flexi fingers sheared when the whole clutch dropped off the drive shaft. Lock bolt worked loose.

Stator - static and attached to the under chassis.

Brake - offset on the stator body to stop the clutch plate rotating when disengaged. (Top of stator in picture)

Rotor - spinning with the vertical engine main drive shaft. (Keyed)

Clutch plate - floats against the rotor and only spins when the magnet attracts it to the rotor

Pulley - attached to the clutch plate with flexible fingers (studs fixed hard and don't let fingers move or rotate)

D-drive - still missing. But could be fabricated on a lathe.

Bolt - Found.

Enjoy.

any good deals on self propelled mowers at the moment lads? the gearbox on woodies prolawn 21 inch has given up, budget of 500-750 i suppose but could go more if need to

I start mowing when grass is high enough to trigger ms. jou's reaction, so no, not yet. ;-)

When the ground is no longer mud with grass on top and can support the weight of me and the mower without either sinking into it.
