I recently added the option of dual sets of front hydraulic couplers. Those are on a steel mount directly in the way of straight access from the right side, steel extensions or not and I am not sure removing the oil filter will help much, maybe; I think TN Mark may have dual sets of front couplers too. I still have to struggle and do the Houdini act to get the flex hose on from the left. Once the coupler is on, then it is tedious to hold it straight and firm enough for the grease to enter the zerk instead of just blowing out the side.
