I wondered if the forum members could help me with a problem...
I have a Greenfield Fastcut 34 - 25hp model that has recently had some trouble starting. The progression of the issue was:
1. Wouldn't fire every time (when the key was turned, it just clicked).
2. For a while, I could move the mower and sometimes it would suddenly fire and start up.
3. Now it won't fire at all.
My initial thoughts were battery or spark plug (I'm pretty novice at this stuff) but when I was looking the machine over, I noticed this wire appears to have become unplugged:
It looks like the black wire (2. in pic) has come free from the white plastic housing (1. in pic).
However, the white plastic housing has two possible connections. The one on the left has a single orange wire exiting from it and the connection on the right has two red wires exiting from it.
I'm certainly not crazy enough to just go connecting them, but I wondered if anyone knows off bat if that's my problem?
Alternatively, if anyone has the same mower and is able to take a picture of the wires (they are just above the main pedal when you lift the bonnet up), it'd be great to see if these should be connected.
Hi Rich, welcome here we try to help. First question is the battery charged? no point going any further till a few things are established first. With the unplugged wire is there anywhere close by that looks like it might plug into. The wiring on these is pretty simple. Battery to solonoid, solonoid to starter motor with a small wire from the solonoid going to the ignition switch. Any other wires in there are for the charging/lighting and have nothing to do with the starting of the motor. The motor has magneto ingition so once started only a kill switch wire is required to kill the magneto to stop the motor
The wire has nothing to do with the not starting. First thing now is to get to the starter solonoid. Follow the positive wire back from the battery and that will take you to the solonoid.
Sounds to me like a bad starter solenoid or related wiring. The battery in these is at the back and cables run all the way up to the motor. trace them through and check for rubbing/shorting. If that is all good, find the starter solenoid. The usual test for those is short the terminals with a large screwdriver briefly to check that it cranks. If it does but not on the key it is likely that it will need replacing.
Those wires up front are for a different engine, they use the same loom between models and some don't use all plugs.
I will have a look this morning and see what I can work out! I think I was hoping it was a simple fix of plugging wires haha. With coronavirus it's pretty hard to get anything else sorted.
Anyway, I'll trace the positive wire and let you know.
Ok, so I think it's fair to say that tracing the positive is probably beyond my capabilities as it basically goes right through the machine.
I think in all honesty, I will have to try and find a repair shop that is open and take it to them. I'm always keen to try and learn things, but happy to step back when I'm likely to do more damage than good haha.
Quick question: It definitely wouldn't be the spark plugs? I took these out and they were quite black...
When it first started to be an issue, I could get it to fire up if I rocked the mower gently, it would click a few times then just work. But it will no longer do that.
Yep, that's it! Think of it as a heavy-duty relay, as that's what it does on a ride-on. Car/truck starters have a slightly different solenoid setup, but we needn't go into that.
Cheers, Gadge

Just be careful bridging across the solonoid that the cutter is disengaged and the foot pedal is in neutral (middle) because when you bridge the solonoid the motor could fire up and take off somewhere. Key has nothing to do with it at this stage but if it happens to start at least you can use the key to switch it off
