Hi there, I'm a new user after some help and much needed guidance.
I have recently been given a Greenfield tractor 11 28" model. I have been given it in pieces and am currently trying to overhaul it. I have done some research and found out that most parts cannot not be brought now. I have managed to get my hands on the parts manual for it but it doesn't give much insight as to how it all goes together. Not to mention I'm not sure if I have been given all of the parts or not yet. I have got as far as working out the clutch. And now I'm stuck and I have a frame with wheels and the clutch installed and I have a bucket full of loose parts I can't work out. Can anybody offer some suggestions or know the best way of working out the rest of the parts. Any suggestions would be really helpful.
Hi Jared, welcome here where we try to help. Is the machine assembled to in as the pic is, if so looks like it is only the cutting deck that is missing. If that is the case then if you put up some pics of the parts you have then hopefully we can identify them and where they go.
As Norm says photos of the remaining bits will help heaps. If you have everything hopefully it shouldn't be real difficult to get this old girl back on the road.
hey thank you. I have got the cutter deck and replaced the bearings and cleaned and painted. Unfortunately the thread on the pulley was severely damaged. I have been able to modify it. Hopefully it works just not sure until the rest of it is up and running. However, I have got the pictures of where I'm up to at the moment. Hopefully these pictures show clear enough. Any suggestions will be greatly appreciated. Thank you in advance for your help. If anyone needs individual photos of each of the parts let me know.
Is that absolutely all the parts you have left? If so you might be short a few. Not to worry though as I know a bloke.......
I think the best way to start this process is if I take a bunch of detail,photos of mine and try to show you where things go. Unfortunately I'm probably not going to be able to do this until the weekend.
In the meantime can I trouble you for more detailed photos of the machine as it is to get a better idea of what is already on it and assembled and also photos of all the remaining parts?
I notice too that the drive belt tensioner bracket is upside down. Don't stress about it as it'll probably be easier to assemble the tensioner with it out.
If you can wait until the weekend please and then we can get down and dirty with this project.
Yeah that�s no worries. Thanks for your help. In the meantime I�ll try and take as many photos as I can so that you can see where it is at for the time being.
There's a fair bit of a difference between the Tractors and the Anniversaries when it comes to the deck and cutter belt arrangement. I was planning to use my Tractor 8 and the collection of wrecks ( ahem, part collection ) as photo subjects.
I chopped up and sold off my Tractor a while back. My Anniversary has the alloy cowl on the front of the bonnet so there is a bit of crossover there. I noticed on Gumtree where a bloke not far from me has 6 Greenfields for sale. Looks a bit of a mess though and the price he wants is a bit high but as we know with the factory gone parts are going to become a bit hard to find. I don't have the room to get them to wreck for parts to help people out.
ok here are photos of the parts I have assembled so far and individual photos of each part I have left. With the clutch assembly I do have the little insert that goes on the center bearing. I just need to get a new clamp for it. Hopefully these photos are ok. Whenever you get the chance to help, if there is any other information or photos you need let me know. Thanks again for your help. I'll have to do the photos over a couple of posts due to there being so many. here are the first few.
Ok Jared, just so we can understand where you are up to, is the drive side of it complete? If that is the case you are looking at mounting the cutter deck and connecting that up?
and the last. I still haven't worked out if I have bitten of more than I can chew yet. If there are a few parts missing. With the factory out noiw what do you think the chance are of getting the parts that are required?
Hi Jared, the factory stopped supplying parts for these a few years ago so the closure has no bearing on it, still plenty of Tractors out there to scavenge parts from. Plenty of people restore the very early Tractors and they are much harder to find bits for and with you being in QLD that is where the majority of Greenfields seem to be. I would say prd is going to be able to help you more than I can because I don't have a tractor to reference all the bits you have disassembled there. It is probably worth your while to hunt down another Tractor so you can see where all the bits go and then you also have a pile of parts you can use if needed.
Jared, to quote the "large friendly letters" on the front of the Hitchhikers guide to the Galaxy:
DON'T PANIC!!
I don't think you've bitten off more that you can chew. This is well do-able. I suspect there might be a few bits missing but we can work that out, I've got a fair collection of bits we can raid and as Norm says there is always wrecks coming up on gumbay. At this stage I can't see anything that you need for the frame that I haven't got here. A bit of postage and the problem is solved
I'll digest the photos tonight and we'll work out a plan. I reckon we might start with making sure the drive (transmission) is right and then we'll have a look at the deck and finally the engine.
This process might take a while- a few weeks but at the end you'll have a working example of the best model they ever made and the forum will have a 'how to' thread that may be of value to others in the future.
Ok thank you. I�m not sure if the drive is completed yet or not. I�m hoping I�m not missing too many parts but see how things go. You guys have reinstalled my faith that it might be mowing again one day. Thanks for your help.
Firstly, I don't know what you mechanical background or ability is. I'll assume it to be middle-of-the-road and we can adjust to suit you as we go.
We might start by discussing the drive starting at the engine and following the belt back to the drives themselves.
All good at the engine judging from the photo. The drive belt should be in the top pulley groove - and it is. Did you assemble the pulley onto the engine or was it already there when you bought the machine? If it was already there, I'd put a spanner on the bolt that secures it and just confirm it's tight and not just sitting there loose. There should be a guard mounted around the cutter belt at this pulley. Don't worry about this for the moment. The cutter belt needs to go on first and I can see the guard in you collection of bits.
Moving to the idler pulleys, I'm wondering if you've got the correct pullies fitted. The photos aren't too clear but they look to be too large in diameter and the belt looks like it might be rubbing the steering shaft? These pullies should be flat and not 'v' shaped in the sheave. I think the two new looking pullies in your photos are the ones you need.
Photo below shows the pullies you need and show the flat groove that the back of the belt rides on. (Note the bracket in my photo is normally welded to the machine- I removed it with an angle grinder )
Your first photo of the machine shows the tensioner bracket mounted upside down and the tensioner assembly is still in your collection of bits. Below is a rough out of what we're looking for. Note also from my photo that you're missing the little spring plates and attach bolt (I've got them clamped with a zip tie in my photo. Have you got these spring plates in your collection? If not I'll send you some.
We need these spring plates fitted to be able to continue with assembling the tensioner. Also, we are going to need to find out if you have the stepped bush that needs to be in the slot of the tensioner arm to allow it to slide. Probably best if I draw you a sketch.
Hey thank you for that. I am a fitter and turner by trade so I have a fare bit of mechanical exposure. I have never had anything to do with ride on mowers. So this is a new experience for me. I have changed the pulleys like suggested. However, I noticed in your pic that there are springs on the inside of the pulleys. I only have the one spring that looks to be the same size. Are these common springs that I can get from a mower shop and is there more parts behind the pulleys?
Excellent! You've got a trade background so we can move through this a bit more quickly.
The spring plates could be made as they are just literally bits of spring with a bolt hole but honestly it's probably just easier if I post you some. The bolt is just a common 1/4" bolt but I can send that too.
Good question with regard the springs on the idler pulley mount. To be honest I can't remember if there are washer etc in the mounting setup. I'll take apart the one in the photo and send you the springs and anything else that might be in the setup.
I've done a quick sketch of how the tensioner goes together. The key to its function is that the large coil spring pulls tension onto the belt and the spring plates we are discussing lock into ratchet grooves in the arm so that the pulley is locked forward once it has been pushed there by the coil spring. The ratchet mechanism has to work or you'll get belt slip.
Handling the tensioner with that coil spring can be a bit like playing with a rat trap. There is a hole in the arm with the idea that you can compress the spring and put a nail or the like in the hole to keep the spring locked compressed while you install it and set it up. Personally I never use it. I lock the spring plates away from the arm with a zip tie like I've done in the photo just wrestle it all into place
Had to muck about a bit to get the sketch to upload.
Send me a PM and I can get these bits to you.
I'll try and get some photos etc organised during the week and we can move onto other parts of the machine and hopefully we can get this machine sorted for you fairly quickly. That said, my weeks tend to develop of their own accord and I can't ever know how long the days will be. We can but try.
I do have the bush that is pressed into the bearing and pulley but I haven�t got the small bush that sits in the slot on the top bracket. Is the smaller bush supposed to sit inside the slot?
I can get access to a lathe at work so that one should be ok. Thank you. I actually have an old bush from one Of the pulleys I replaced. I should be able to machine that one down to fit in place
Umm, if you mean the bushes in the pulleys you originally had in the as the idlers PLEASE DON'T at this stage. I've got a sneaky suspicion those are the pulleys that go in the cutter clutch- and those bushes will be needed.
Dimensions for the bush we are talking about aren't super critical. From memory it's a 3/8" ID for the bolt ( please check) and the small outside diameter is the same as the slot, of course. Height of the small diameter is such that it's slightly more than the thickness of the material the slot is in - maybe a maximum of 1/16" more. Large diameter section needs only to have enough diameter and height such that it will give sufficient strength and bearing area. I'm surprised I can't lay my hands on one. I'll check again.
I'll send you a PM as I'm going to need an address to send these bits to
