I have the Land Pride brush cutter for my skid steer. I'm supposed to check the gear oil every 10 hours. The problem is where the square plug access for the gear oil check plug is blocked by a bolt. I tried a swivel attachment and still not enough clearance. Anyone know I can use? I tried a gear oil plug set and it's not short enough. I pretty much would need the square plug removal tool on a 90 degree with a short handle.
