I recently purchased an new 3540 w/loader. I plan on removing the loader from time to time to work in places too tight for the loader. Seems easy enough to remove, but I am looking for some hydraulic dust plugs and caps for the 4 hoses that must be disconnected. The female coupler remains with the tractor and without a dust plug would soon be filled with dust and trash. Does anyone know the size of these couplings? The rear remotes are 1", but the ones on the loader are smaller.
