rotovator fuel help
« on: March 30, 2009, 23:17 »
Our allotment site has had a rotavator donated (fab huh) - i am trying to find out what type, but apparently it runs on 4 star fuel...................... now as i understood this you cant get this anymore........... so...........
if we can still get 4 star where from?
if it can run on unleaded is there anything we should be doing to make it ok?
what fuel shoudl we run it on if the above are'nt viable?

asking on behalf of the chair and other plot holders
will try and find out what sort tomorrow when i get up there and let you know (i dont know i guess it might make a difference)

Thanks

I can't imagine that there are any rotovators left in the UK that haven't been run on unleaded now.... Having said that, there's always a first....
I expect ( but wouldn't want to put any money on it untill we know WHAT rotovator!) that they meant four stroke petrol, as opposed to two stroke.

However, if I'm barking up the wrong tree, you can get an additive to put into unleaded petrol to boost it a little.
We do need to know more details about your machine. Briggs have been fitting hardened valve seats (needed for use with unleaded petrol) for donkeys years, they were using unleaded in the USA long before we started using it over here, so if it's a briggs engine, you will be fine using "decaf" petrol for sure.
Keep us posted.

Hello,

I wonder if that is Cultimatic rather than Cultivator.??

   Qualcast Cultimatic Super had Suffolk 98g14 engine.
   
         Cultimatic Special had 3hp Briggs & Stratton

             ....and the Cultimatic De-Luxe had 4hp Briggs & Stratton

If it indeed retains its B&S engine...  then on the cowling tinwork...perhap the flat vertical section facing the carb/air filter you should see 3 series of numbers stamped into the tin..they may be rusted or painted over..but they will be there unless a new cowling fitted at some stage..

With these you may be able to obtain a representative operating manual starting form this link;
http://www2.briggsandstratton.com/maint_repair/manual_and_more/

The last set of numbers Code will give the age away...first 2 numbers this Code series being the year of the engine...perhaps 79  as in 1979 or thereabouts??

Indeed if it is B&S 4 stroke then as mentioned... Unleaded petrol for the fuel and SAE30 oil for the sump oil.

I should add that Cultimatic that I refered to previously was a "harvest gold" sort of colour with white handles etc.

There was a later Cultimatic B66 which was all but the same as Merry Tiller Cadet..it was green with Qualcast Suffolk Atco A114 4 stroke engine.

I did not pick up one question....

I believe the word "Rotavator" is/was?? a trademark name.. of Howard ??...hence I suspect another name was used.."cultivator"...and Qualcasts own model name "Cultimatic"..whilst others may use "Tiller"??

so can i assume that they all do the same thing, regardless of their name then? i.e. turn over the soil and chop it finely (ok i'm sure thats not the best way of describing it but i am a total newbie to allotmenteering)

More or less....however with some machine types there are a whole range of tines to suit different jobs....
For instance on the Merry Tiller range there were the general rotavating use Slasher tines which I think would be slightly heavier in design and more curved blades than those on the Qualcast Cultimatic...then they had the Finger tines for working down a fine tilth on the top without tearing it up deep...and various other wheels, tines, etc almost ad-infinitum...

I seem to recall that the Cultimatic Slasher tines would be of a more general purpose type....but I think there may have been finger tines to suit ??....and I think a set of wheels too.??
