i have L2800, pto issue. i start my tractor, get the rpm's to pto speed, i then push in the clutch and then push the yellow handle to the right of the seat, i then slowly let out the clutch to engage the bush hog. nothing happens, the pto wont engage and start the bush hogg. it is my understanding it may be the yellow handle cable lever on the right, the cable may be broken inside the black plastic covering the cable. i reach just under the seat and grab the metal cable and have another move the lever back and forth but i cant feel the metal cable moving. im not an experinced tractor man, need some valued help here and appreciate all the help i can get. thanks
