You don't want one like that, the blades cant spin on it.
Most of the small Cat 1 Woods type mowers like this come in 48" (4 foot) and 60" (5 foot), but there are some out there in 72". but I really don't think the smaller Kubota tractors would be well fitted to running a 72" mower unless the grass is fairly short. Not because they lack sufficient power, but most of these mowers are 540 rpm mowers that operate at a slower speed and the wider the width the less effective the mower may be using a smaller compact tractor.
My 35 hp Ford Jubilee wouldn't handle tall grass with a 6' foot brush hog, wouldn't even think of it with a 6' foot finish mower like this one.
So I've got an issue with the brake axle pivot bit. It looks like there's a mini "axe pin" on the left held with a bolt. I have removed the bolt and it will turn with force but it won't come out so I can remove the brake shaft.
Also were these metric or imperial as some metric sockets fit some bolts but not all.
Rods like pistons are sold in off sizes, over sized for pistons and undersized for rods. That way if you have to remove material off the crank you can still purchase a rod for it.
That looks fantastic Alain. Looks like a very Large Bolens too.
Very Interesting development in this tractor. It is not a 1965 David Brown 990 Selectamatic, but rather a 1964 David Brown 990 Implematic. The Model number is H990/UA, s/n 471597 (December 1964). The "U" the model number means it was special for the American market, and why it has 990 Selectamatic tin on a 990 Implematic tractor. There was an import deal with Bolens to the American market. The reason for the color change was to make them look like Bolens tractors. The "A" meant it is an agricultural variant. The Implematic had the 6 speed Hi-Lo with 2 more speeds in reverse and the Selectamatic was a 12 speed 4 range (low slow, low, high slow, high), with the ability to up shift from 1st, 2nd, 3rd and 2nd to 3rd and to downshift from 3rd to 2nd in any of the ranges without stopping. The David Brown 990 Implematics made for the European market were red with a rounded front hood. Still the engine and drive train are extremely proficient for agricultural work. And on the collector side a very unusual tractor here in America as CASE was selling a comparable tractor at their stores and had the benefit of a huge name recognition here compared to David Brown.
In another interesting piece of trivia the management of David Brown saw a classified advertisement in The Times in 1947 offering for sale a High Class Motor Business, which turned out to be the sale of Aston Martin. David Brown acquired Aston Martin for £20,500 and, in the following year, Lagonda for £52,500, followed by the coach-builder Tickford in 1955.
David Brown subsequently concentrated all the Aston Martin manufacturing at the Tickford premises in Newport Pagnell.
The David Brown years saw production of the legendary DB series of Aston Martins, which were featured in some James Bond films. David Brown also had connections with Vosper shipbuilding, and Delapina and Radyne machinery.
Both car companies were sold in 1972 to Company Developments Limited, when Aston Martin was in financial trouble, for a nominal £100
Thank you! I will have to investigate a bit more when I return from uni at christmas, yes it is a Delco Remy starter. I didn't have the time to look at the engine too much when I was home but I think it is the original, I'm always sceptical when someone says the 'tractor was running 5 years ago', I always wonder if it was put away as something broke, I guess I will find out when I strip it down.
I call it Tractor SFU; Special Forensic Unit. You literally have to go back in time and find out what each and every owner/operator did to the machine and how to remedy the issues and repairs. These types of enquiries are not unlike scientific enquiries you will do at Uni. I've done this on 30+ machines and it never gets easy, but the knowledge you attain does transfer into real world problem solving. You're going to be very successful.
They made the executive model in 1963, 1964 and 1965 I think, each year there was quite a few changes to the styling. I am pretty sure it is a 1963 7E (executive 7hp) as there is a few things such as the aluminium steering wheel and the foot pedals that make me think it is the 63 model. Unfortunately someone cut off the piece of metal which went at the top of the hoodstand, this had the serial and the model number on it. Very frustrating! Also the engine serial number plate on these Masseys were positioned on the top engine cowl, this has also been removed at some point. So at the moment we are unaware if this is a 7 or 8hp engine. It looks identical to my cub 7hp engine apart from this one has a fuel pump, does anyone know if this was an option on a 7hp kohler? Is there any other markings that will help me deterring the HP without pulling the head?
Thanks
The Kohler 7hp (k161) and 8hp (k181) both had a bore of 2.938 inches. The only difference between the two engines is the stroke, with the k161 being 2.500 an the k181 being 2.750
Duro Corporation made the first Massey 4 wheel mowers, followed by Beaver MFG which built the first year MF-10 in 1965, In 1966 taking the Beaver MFG design AMP of West Des Moines, Iowa built the MF-10 and in 1967 added the MF12H Hydrostatic model. The MF series continued with 8-16 hp models. The Tecumseh powered tractors were MF-7, MF-8, MF-10, and MF-12 hp models and Kohler powered machines were the MF-14 and MF-16. July of 1976 was the last of the MF series and the newer 1000 series (1200, 1600, 1450, 1650, 1655, and 1855) appeared in the fall of 1976 as the 1977 model year, that series only had a 2 year run until 1979 and there wan't another Massey mower for nearly 10 years after that. The next Massey tractors were built by Case/Ingersoll and were copies of there 200 and 400 series mowers, that run also only lasted two years and then Simplicity was contracted to build Massey mowers in the late 80s early 90's and have ever since. Massey never actually produced any lawn and garden machine themselves.
I bought this today to use in plowing, discing, and harvesting. 1965 David Brown 990 Selectamatic 55 hp diesel. Rear remotes and everything works as it should except it needs headlights 3250 US.
Just kidding, the Mowett was pretty stout for a low cost machine. Sometimes we forget that economy machines were available to the consumer even when the best machinery in the world was being made as well, however most of these economy made products disappeared rather quickly, deemed not worthy of saving. Now we see that there is an interest and a worth in them and there are very few around.
