I work for a municipality, we just got a new B7610 a while back. I have been using it to pull our old horse grader. This is a 2 man operation one on the grader one on the tractor. I would like to make the grader hydrolic as the labor is not available. This means I'd need 3 remote hydrolic sets (6 couplers). tractor has what (from reading on here yesterday) the 4 way valve for our front snow blower. Can I add 3 rear dubble acting remotes some how? I'd prefer seperat leavers for each remote. Can I put a prince 3 spool or somthing on for rear remotes in addition to the joy stick? has some one done this? good mounting spot? I also have plans to convert and widen our ag fab sweeper and would like to run the brush with a hyd motor also possibly hydrolic dump. Do i need to add a oil cooler to run hydrolic motors all day? Special valve consideration? So far like the tractor except for a canopy vibration which I hope to get stoped soon. also the exost dumps on the outer weight (factory option we added). Thanks
