Changing the tranny/hydraulic on my tractor after splitting it and replacing the gaskets . Kubota wants $85 for a 5gl pail of UDT, Tractor Supply sells a 5gl pail of Super Trac 303 for $26.99. The back of the pail says that it is Kubota compatible. What is the general opinion on the use of the Super Trac from Tractor Supply ?
