Many thanks crumpet for the extra photos. They are a huge help. Amongst other things they clear up my query about the blade drive. What an ingenious idea to use the transmission 'idler' belt for this! For all our leg pulling and smart comments it turns out there is a certain elegance in the belt/drive layup.
Trump-cat, I can't agree. While this particular example clearly demonstrates the key features of the coolbutt range I am certain from 'hard' experience that it is more likely from their sorebutt range of classroom furniture.

Hello prd and GF followers I feel that is an important technical point, prd. The serpentine belt drive connected the forward/reverse clutch pulleys, but also gave drive to the cutter deck. But input to the forward clutch seems to have been via a belt from the engine PTO.
This arrangement is too good for a back-yarder job - isn't it? It's not an XL or Stallion - as Norm has said. I feel prd needs to say its a Greenfield and give that scratch-it to himself. Are you a gambling man prd ...?

I see, prd ... But which came first?!!!: the CoolButt� or the SoreButt�? I bet old Theo was behind that project too!
Trump-cat, not sure which came first, the CoolButt or the SoreButt but I'm certain they sold way more of the SoreButt range! Schools were full of them in the '70s and '80s
Not a betting man but prepared to bet heavily that that machine is one of Theo's inventions since crumpet's 'reveal' post. All we need to do is find some evidence. If only Trove........ah..., we've lamented this in the past! No point doing down that road again.
To me it looks like it could slot in after the horizontal engine HD8 type as this used a horizontal engine but it also incorporates the heel/toe clutch design. I'm still thinking it is possibly a prototype, but it also has brackets and components that appear to be from a production machine so it makes it very confusing but too many things point to it being a Greenfield
Thanks PRD for pointing this one out. This machine is about a 1979 Greenfield Javelin. Has this got any numbers above the front axle? If so it is a production model. Design instructions to Mr Kerr were a mower you sit into like a formula one car of the time. Seat is not original but would have been an vinyl padded seat like a race car had. Predecessor to the 5xl. If you think the 5xl was a fail this was even bigger fail. These are rare as rocking horse manure now so lets keep it for prosperity.
Quote from greenhorn, "Design instructions to Mr Kerr were a mower you sit into like a formula one car of the time." Seems to me Mr Kerr was in the design department at Greenfield, the fact the other "Mr Kerr" was in the news around that time was coincidence
Hello Lewis These are never-before-seen WWW images of the Javelin. On behalf of ODK History I thank you for them. I know some 'Greenies' are losing sleep with you posts!
Many thanks for giving us a more complete record of the Great Greenfield.
Obviously this is the forerunner to the 5XL and the Stallion using the rear engine design which with each one I had the motor at the rear took some weight off the front steering
Yup! Too true Jack, us Greenies are just loving this stuff!
Once again, many thanks Lewis,
I find it curious that, broadly speaking, folks in this country always seemed to gravitate to a tractor style machine. The other 'small acreage' designs just never seemed to hit the mark with the punters- and not just a Greenfield phenomenon either. It seemed to be across all manufacturers.
