To find out which is slipping easily, determine whether the PTO speed is staying constant with the engine, or the rear drive. If the engine clutch is slipping, the pto will slow when it slips. If the M&W clutch is slipping, the PTO will be turning correctly with the engine, but the tractor will slow down. If you can tell how fast the blades on a bushhog are turning with the sound and feel of the system (experience). then pull a bushhog into some deep stuff to see if the bush hog and the tractor slow at the same time. If they do, and the engine is still going at a higher speed, then the master clutch is slipping. To check the M&W, start in high gear from a stop with the PTO turned on. Have a friend stand behind the tractor (on the ground, not riding) and watch the PTO. If the PTO spins up fast and the slipping occurs at the rear axle, it is the M&W that is slipping. The MD clutch will need a 3/4 to 1" space from the front of the platform where the pedal hits to the clutch pedal arm where it has the stop. This is free play. If adjusted and still slipping, as tested above, it needs a clutch. Good luck, JimN
