Unfortunately unless someone drilled a hole underneath there isn't a drain hole. Good luck with the hoses. I had to do all 10 hoses on my b7100 loader and repair all 4 hard lines. Wasn't cheap but should last me many yearsExcellent, thanks! I am going to take another look under the FEL post (aka the reservoir) to see if there is a drain plug under there and will definitely remove and clean filter - I have about 6 high pressure hoses to replace (split, webbing underneath rubber showing) and will replace low pressure hose at the same time as mine are pretty hard and aged
