Not sure of the belt size Glen but there are others that will give you the info. As far as your plugs are concerned, any 18mm lomg reach ones will do the job, 15 to 25 thou gap. And welcome to the Forum.

TVO Cropmaster help

Post by Joe90 » Fri Aug 07, 2009 9:44 am

Glen, I bought my fan belt from www.davidbrownparts.com and very helpful they are too. I use NGK AB-2 they are compatible with K97F but are a wider heat range plug and run better especially on oil burning engines, available at low cost from Ebay via a Manchester NGK stockist. Regards Joe90.

Cheers for your help chaps hopfuly i will be able to get delivery of the plugs tomorrow from the motor factors i use at work fingers crossed they will stock them,
Then all i have to do is put the tractor back together i was told when i bought it all it needed was 4 new plugs a fan belt and a battery to run and as far as i can see not many other bits to finish and a top coat of paint
i will try to post some piccys tomorrow after i pick it up,

Thanks for the warm welcome

Hi glen

Our copmasters have no trouble running on the ab-2 plug and as joe90 has said they are a very reasonable price. Fan belts too wont break the bank but just make sure you specify that you don't have a belt driven dynamo and you should be well away.

Cant wait to see the pictures

Finaly got my cropmaster today, had a tinker for a couple of hours and found a couple of things..... panels dont seem to line up very well (main bonnnet to rad grill) nothing major and i cant seem to find any bolts in my workshop to fit anything, would it have BSF nuts and bolts?? also i think the throttle linkage from the hand control to the govener is missing if anyone has a picture of theres it would be a great help and there isnt any wiring on it at all except for the main lead from the starter which i assume goes to the possitive battery terminal... can anyone advise how to wire the dynamo reg? and does the ignition switch just earth out the mag when in the off position??
