Hi, new house, big garden, polytunnel (more of that and it's renovation later) plus a possibly knackered ride on mower.
So sorted the fuel leak, not yet got the belt that empties the back, blew up the flat tyres and got it started. Headed out into the garden and it cut the grass for about twenty metres then drive to the blades failed. Belt is good but the drive pulley isn't turning. Any ideas, or a new mower?
Thanks
Tony

Is the electric clutch kicking in?

Guys, sorry, no idea, used to pushing a little power mower around.
Do I need to get this up in the air and dismantle from underneath or strip from the top?
Apparently something similar has happened before, according to neighbour. Previous owner got it bogged in the gravel on the front drive, getting it out the garage, like I did this afternoon.....

I'd check that and the fuse/relay first. Clutch is underneath.

Also there is a small lever under the LH footboard that slackens the belt to the deck (for removal of the deck).
It can get knocked slackening the belt which then doesn't drive the deck.
Also if there is no one sitting on the seat when the deck drive is engaged it will cut the drive. So get some one to sit on it with the engine running and the cutters engaged whilst you look to see if the pulley on the engine is turning
I am assuming its a modern one with an electronic clutch for the cutters

Forgot about the lever. Mine kept working loose so cable tied it in the end.

Thanks for all the advice, think I might have solved it.
It's a very early model about 20 year old. Everything is loose, only one bolt actually holds bonnet on, dash panel broken, some lights on it but no clues as to what they are etc. Choke cable seized. Can't auto empty bag if I can fill it as there's a belt missing I believe.
Anyway there's a toggle switch on the dashboard that you have to click off before the cutters work which is against what the symbols indicate.
Chucking it down here today (again)(Oban) so driven it into the polytunnel (through the doors) and will try it once it dries. Not attempting garage with deep gravel again. Still that means room for the car.

It's not the seat switch is it? Mine had a cutout on the seat, so if you removed yer bum, it stopped the blades. Long time ago, that switch may even have killed the engine altogether... I wired it out...

No, just this switch on the dash it seems. Next prob is the grass collector doesn't. The PTO under the seat isn't rotating but the belt is complete if a big tatty.

The toggle switch on the dash is the on/off for the cutting deck smile . It goes past centre then clicks back a bit. And needs to be flicked to turn it off.

On a C600 that old I doubt you have "auto empty". I'm not even sure the new ones have it? You reverse up to your compost heap/neighbours drive and there'll be a shaft/broom handle sticking out of the top of the grass collector to your left. Lift it, and pull towards you and it will flip the back up and dump the contents.

Are you turning the PTO on?

To your right should be two levers. The outside one will have 10 notches in it marked 1-10. This adjusts the height of the cutting deck.

The inside one is the PTO lever. Upside down L shaped groove. Slide it across and down and that should turn the PTO on. As noted above, if your safety switches are working you won't be able to see this with the seat up...but you'll hear it working (if it is).

I have a sheared axle on mine...am just toying with repairing the gearbox as the pro shops round here treat it as a sealed unit (so £750 rather than £200 to fix it frown)

There should be a lever to engage the PTO (if you were scratching your nuts keep going south by about 6 inches...should be there (assuming you are sat on the seat!)), mine is lever up to engage.

Mine's a 2010 model but I expect the basics are similar.
There are two belts from the crankshaft pulleys driving the rear. On mine the top one drives the transmission. The lower one drives a pulley on the transmission which is connected via a vertical shaft to the PTO pulley. Sometimes this belt comes off. With practise, and having removed the grass collector I can feed the belt back onto the pulley. Don't know why it comes off, a winter job to investigate.
BTW I use belt conditioner on my machines, it makes them slightly sticky reducing slip and wear

This one is supposed to be down to engage but beginning to wonder...
I was told there was a snapped belt but thought it was the one that turns the collecting brushes as the one from the PTO to the grass box is not snapped.
And yes there is a big lever to empty you're correct, just need a way of getting the PTO to operate.
Onward and upward, the garage door is stuck in the open position now.....

Mine was lever down to engage PTO to collect clippings. There's also a hidden drive belt inside the PGC - black cover at one side of PGC - if that's toast then the brushes won't spin.
Blades were button on dash, which then engages the electric clutch at the front to turn the belt powering the cutting deck. That tensioning lever would be a favourite for loosing belt tension and therefore blade motion, lever hidden under the footplate, can't remember which side. Could also be a fuse or a relay on the main board above the fuel tank if no power to clutch when dash button pressed (watch your fingers!!).
Seat pressure switch was, erm, under the seat. I think it cut the engine dead a few seconds after leaving the seat. Won't be that.

Thanks Andy, the way bits keep working loose it looks a bit like that exploded diagram!
Yes I think it's the belt under the black cover that might have gone but not looked yet.
And another thing, when using it yesterday, the fore/aft lever is not very positive and selecting reverse was getting more difficult as the evening went on. As I said, it's pretty knackered, probably only a couple more cuts this year though so might go looking for a new one ready for 2018. (subject to sale of old place).

Tension. Worn belt. Both. Maybe your belt conditioner smile

Fore/aft lever? For belt tension or the foot pedals?

Check the various connections on the linkage. They can vibrate loose which prevents full movement. Does it feel like the pedals are stiff? Or are you just not getting movement?

(Even new ones will get issues pretty quickly IMO owing to the hammer they get. It'd be worth getting to know it...technically they're pretty simple. (I may live to regret that this weekend smile). New ones are also 4k+!

Sorry, fore/aft lever=the one by your right hand that gives either forward motion or into reverse. Except reverse is not always an option.

Can you take a photo of your tractor from above showing the dash and the footplates?

The way to make mine go backwards and forwards is via the foot pedals.
