Help! Where can I find a wrench to remove the oil filter on the Mahindra 3616 HST? It appears that this has to be the "cap" type of wrench that attaches to a ratchet. In my opinion, this is a very poorly designed place to locate the filter on this tractor -- very difficult to get to, with hydraulic hoses and other obstacles preventing the use of regular filter wrenches. I can't find a "cap" type that fits the filter for this tractor, and I'm at the 50 hour point and need to change it right away. Any dealers out there that have one, or can someone suggest one?
