Cheers thanks ,I should have asked on my last post what oil the transmission uses , it has been suggested that it should be kubota udt whick i think will be equivalent to the oil for mf , jd , nh wet brake transmissmions.
UDT is needed for tractors with hydrostatic (HST) transmission. The L2850 has gear-type trans and hydraulic pump(s) so regular multi-purpose tractor oil is fine.
