Hi HayterNovice, and welcome to TGMF..

It's likely to be one or both of the rollers dropping out of drive as you mentioned. You can usually see them slipping by holding the machine slightly up by the handles, engage the drive and slowly lower it to the ground observing the rollers, see if one of them is stopping.   

What is the model of your harrier? (On the silver sticker, example 490D).

Hi all I would appreciate some advice on a hayter harrier 48 ad vs 2019. It seems to kick left and right when left to drive on its own. Is it thT the roller is physically slipping causing it to switch from left to right or is it something mechanical on the split rollersystem or something else?

Thanks.

Greg, do you mean the bowl drain bolt?  That's all I can think of, as some have them and some don't.  It's just a drain.

Not got a pic at the moment Mick. There's a screw that's attached to the bowl from an angle. Like on some gcv Honda engines. Not sure what they do.

Quote from: Gregs mowing on March 24, 2024, 06:34:25 PMI didn't notice the black plastic plate that goes between carb and engine wasn't on correctly. Could that affect its running?

Yes if it's letting air in then it will cause issues.

I have no idea what you are talking about there Greg, got a pic?

Cheers mick. Will have a look.

Greg, I edited your first post to add those images.

Hunting, either a gummed up carb, Really bad float level, or split inlet tube.

And as you mentioned it won't switch off.  Looks like all is ok there, unless the control plate isn't touching the switch contact.  Make sure it does touch it when in the off position.

If that's ok then you either have the stop wire disconnected from the coil, or a broken wire (Rare), or a faulty coil.

EDIT  Looking at the stop switch it looks like the wire is fitted incorrectly.  You need to push that metal piece the wire is hooked through now, and then poke the wire through the hole below it.

Hello all, it's been a while. I have good news on the mower! As spring is beginning to arrive I have once again been able to get outside and do work on the machine.

Pulley from FB Marketplace was fitted just before winter last year, and I'm glad to say it has done the job really well. Self drive now working brilliantly.

Throttle problem is also now remedied (although carburettor needs another quick clean as still hunting a little bit, but I do have now some proper carb spray and cleaning gear). The throttle problem progressed further before it got better, upon starting the mower it would rev out of control and sounded as if it was about to go into orbit! After much faff I ended up tinkering and resetting the governor, as it seems either it had slipped out of alignment or the previous owner had mucked about with it. Throttle is now lovely and controllable and the engine runs at a good steady speed. :)

Microswitch for the electric start was replaced as had started to fail, and I also ended up replacing the battery connector too on the mower's wiring harness as it was perishing away and didn't fit all too well into the battery itself.

Hopefully I can finally sell the thing now and move onto something a little easier (Briggs 35 Classic, anyone?)

Thank you again for all of your help!

Greg, I don't see the pics on Insta either.  So what machine / engine, and what issues are you having?
