Hi does anyone have any information on the drive arrangement on the 1962 Uni Horse blue tractor, the main drive chains are noisy on mine, sounding occasionally as if they may be almost jumping a tooth, does anyone know if there is a facility for tightening these chains, or was there a ever a repair manual available for this tractor, any help would be much appreciated, as I do not want to strip down more than necessary to gain access to the chains, if advice is available. Regards Chris.
