Gearbox was tight, so I stripped it down and found one bearing was tight from lack of use, now all turns nice and easily. Below are a couple of photos of final drive to wheels and associated clutch, looks to be some good solid engineering.
A search of British newspaper archive revealed an article dated December 1949 that shows the Commando Hoe exhibited at Smithfield Show. Associated photo shows a machine the same as mine.
After giving carb and magneto a good clean and replacing perished HT lead the engine now runs. New throttle cable made. Now to checkout gearbox and how clutches are supposed to work. Clutch to disengage hoe drive does not seem to work.
Reading through ’70 Years of Garden Machinery’ by Brian Bell, it looks as if your rotavator is an early Mountfield M1. These first appeared in 1962 and were fitted with the Kirby Lauson engine, later models had Briggs & Stratton engines.
Just one of the rare machines seen at Weeley a Trusty roller. I have posted a link to video of the SIMAR 10 in a post in pedestrian machines section of forum.
Martin, have you seen this web page, it would be well worth contacting Bob he may have a copy of the literature you want. Please keep us informed of results.
Are you aware of the David Brown canal tractors, based on their model 2D, I know at least one survives.
A brilliant weekend, thanks to all involved in oragnising and everyone that attended. Some were lucky to witness me starting up and running the SIMAR 10E for the first time, it still needs a bit of work to improve starting and running. Photos to follow.
