After reading the description a bunch and asking if it would fit a tym t273 tractor, I bought it. It does not fit without major expense of fittings to adapt it. It is 3" short on mounting holes, all spools and in/out are the same size. I did try to return it, but either I didnt explain it fully or they misunderstood me. I would not buy from them again based on poor explanations of the unit. I rebuilt my existing unit, brings and gaskets, for half the cost.
