I recently bought a L48 without a backhoe. I would like to operate a chipper which requires connecting 2 hydraulic lines. There are 3 factory remotes on the rear; a 1 inch on the left and a 1 inch and 1/2 inch on the right. Can I use these and if so which ones? Manuals are useless. Thanks for your help; new to tractors and to this site.
