I've got an L3600 with a loader. The stock hydraulic pump doesn't move the loader as quickly as I'd like. Is there a higher GPM pump to replace the stock one, or am I better off driving a bigger pump off the crankshaft and using a 2nd reservoir? The tractor does not have live PTO so a rear mount PTO pump doesn't seem practical. It does have a 2000 rpm live mid-PTO....would that be a viable alternative? Thanks
