OutdoorKing Repair Forum Forums Repairs and Maintenance Questions On Ride On Mowers Questions on Greenfield Ride On Mower Frames Greenfield Lawn Tractor 8 Issues

Hi all, and thanks for the add. I have recently aquired a greenfield lawn tractor 8 that has what appears to be issues dis engaging the blades (has a 2 peice pulley by the way). Has anyone got any pics or a manual on the set up as well as the engaging handle for the throw out bearing?. ANY help would be appreciated!

A Pic of the model you have would help heaps.
Also have a look at what the cutter engagement lever & linkages are doing when you move it

Im having trouble uploading a pic off my phone, but it runs a "throw out" bearing that is mounted underneath the 2 piece pulley, the cutter lever when engaged puts pressure on the bearing and the lower half of the pulley.

Problem is without a pic it is too hard, so many mix and match models of Greenfields around that time, and then there is the motor changes and owner mods over time to contend with

G'day Evan,

I'm not sure what you mean by a two piece pulley etc. Is it a very old machine? Is the engine horizontal shaft with the pulley and clutch in question mounted on it - right at the front of the engine??

Cheers,

The pulley that is bolted to the engine is seperated by a clutch and isnt 1 peice. The top half runs the wheels,and the lower half runs the blades. When you engage the cutting blades the bearing places pressure on the lower half of the pulley and engages the cutting blades. Im still having problems uploading pics from my phone, so any help there would be great, similar pulley arrangement to a hd-8 by the looks of things.

Ok, now I'm curious. Definately need photos, I think.

Personally I've not been able to send photos directly from an iPad to this site. Guessing your phone (iPhone?) is the same. Perhaps send the photo to your laptop and then try to upload.
The one and only time I posted photos that's what I did. Haven't done so since 'cause the laptop is kaput!

There is a forum on here somewhere that discusses the HD8 clutch. I'll try and find it. I've not had a 2 pulley one apart but have had the 'Old Red' clutch apart. Be aware that the lining material was asbestos on the HD8s etc.

To confirm, the engine is horizontal shaft? Clutch is out the front?

Cheers,

Top half and bottom half of the pulley to me indicates a vertical shaft motor, bit like pulling teeth at the moment

Is this what you are seeing?
This is what's on my Mini tractor8 ( under motor )



Also if It's what I think it is, Make sure the Deck mounting bolts aren't over tightened (x3).
The deck slides back & forth on the deck mounting bracket to tension cutter belt via a mounted spring on it..




You could try going on this site via your mobile & put up pix.

Thanks guys for your valueble input, yes paul, that is exactly what im seeing.I wont be inhailing near thst clutch anytime soon lol, paul, if you could, could u take photos of the cutter blade lever assembly? I have a feeling there is some sort of spring missing.(to relieve friction from the lower half of the pulley). And if anyone has a manual (long shot i know) can they point me in the right direction? Thanks guy's, wonderful site, awsome people !

Ill have to load my pics up to my desk top when i get home from work, i didnt realise that those bolts played apart in the tentioning, it did come from an old fella who gave up on it so his thoughts were a bit schetchy. I got it as payment for swapping engines on his other greenfield and was left with the rest as payment (the mini 8 and a 8hp briggs).

no spring on lever but there is one on the clutch assembly







The bolt you see(there is 2 of,left & right of clutch) are what you set the space/Gap when not engaged

Thanks paul, i swear if i ever meet you, ill have to buy you a beer or two lol at the moment, there is no contact between the cutting deck handle and the arm that carries the bearing its just flapping in the breeze. Thanks for your help guys.

I think ill loosen the deck bolts off and tinker with the adjustment on the carrier for the lower spring. I think someone along the line has stuffed it up but now i feel i have enough input to finish it off. Ill upload s youtube clip of its maiden voyage lol

No worries bloke, glad I could help..

Well that updates me folks.

I had no idea the mini's ran this sort of clutch. My mini has the normal belt clutch. I'm guessing this means the later ones (the 5hp) that were sold alongside the Tractor X's were different.

I have a donor model that has the same clutch but it's a brighter yellow (original) and the front hood & grill are different also the center section under steering wheel is a tad longer.

Cheers SD,

So your saying your donor has the belt clutch? And is it 5hp or an 8hp out of curiosity? I'm curious because if it is it would appear the clutch design and the other changes probably happened when they consolidated the range with the tractors.

Once again, it appears we can see the evolution of Theo's design. It's logical that he'd have tried using the same type of clutching on his first vertical shaft machines as he did on the horizontal. It appears that after a short while, he came up with a better way - the belt clutch on the Tractors.

Glad your getting it sorted Evan.

Nah, clutch is same as here. but color & many designs are different on the donar. (mini Tractor8) for instance the front grill has 4 horizontal Louvres, horizontal steering shaft is only 1/2 the length

Hi all, just a follow up to my issues. I have placed it all back together and have driven it for the first time in 10 (ish) years. A new problem has risen (lol). It turns out when you put the blades on, it doesnt engage. But i know where the problem now lays (keyway collar is on the old engine which is on another mower), hopefully im aloud to pull the other one apart to retrieve the other collar (dont think itll be an issue).
