The joystick controlled hydraulics on my L180 seem weak. Last year when I purchased a brush cutter it had a ton of power. Later in the year it is really weak. weaker in one direction than the other. I noticed using my plow this winter that it did not seem to have the zip when tipping the plow blade as well. The machine moves fine, and the foot controlled hydraulics operate as they always have. No repair manual on hand. Looking for some advice on where to begin as this is my first skid steer. Thanks in advance
