An impact tool control method and apparatus and an impact tool using the same. Pulses of torque applied to a fastener by the impact tool are measured. The duration and magnitude of the torque pulse are subtracted from a torque signal and the resulting difference is integrated over time to obtain a fastener angular velocity signal. The angular velocity signal is integrated over time to obtain a displacement signal which can be converted to a torque signal. The impact tool can be controlled based on the value of the torque signal.

The turf conditioning apparatus of claim 6 wherein: said first rod has a first and a second opposite end rotatably extending through said frame; and further comprising: a second adjuster arm fixedly connected to said rod and extending therefrom being releasably connected to said frame to allow said rod to be moved to change said angle, said first adjuster arm and said second adjuster arm are fixedly respectively to said first and second opposite end of said rod. 9. The turf conditioning apparatus of claim 8 wherein: said first adjuster arm is located outwardly of said frame whereas said second adjuster arm is located inwardly of said frame. 10. A turf conditioner comprising: a frame having a first bracket and a second bracket; a first rod having a first end and an opposite second end movably mounted to and between said first bracket and said second bracket; a plurality of flexible tines mounted to said rod and having downwardly extending bottom end portions for contacting and combing the ground at a predetermined angle; and, a mount attached to said frame and said rod to allow adjustment and fixation of said predetermined angle and wherein: said rod is rotatable mounted to said first bracket and said second bracket; said mount includes a first arm with a first proximal end fixedly mounted to said first end of said rod and a first distal end securable to said first bracket, said arm includes a longitudinal axis extending from said proximal end to said distal end with said axis pivotable adjustable and then fixable relative to horizontal about said proximal end; said mount includes a second arm with a second proximal end fixedly mounted to said second end of said rod and a second distal end securable to said second bracket, said second arm includes a second longitudinal axis extending from said second proximal end to said second distal end with said second axis pivotable adjustable and then fixable relative to horizontal about said second proximal end; and said first arm includes a collar through which said rod extends and is fixed, said first arm is located outwardly of said first bracket and said second arm is located between said first bracket and said second bracket. 11. A turf conditioner comprising: a frame having a first bracket and a second bracket; a first rod having a first end and an opposite second end movably mounted to and between said first bracket and said second bracket; a plurality of flexible tines mounted to said rod and having downwardly extending bottom end portions for contacting and combing the ground at a predetermined angle; a mount attached to said frame and said rod to allow adjustment and fixation of said predetermined angle; and, a second rod parallel to said first rod and having opposite ends movably mounted to said first bracket and said second bracket, said second rod including a plurality of said tines mounted thereto with tines on said first rod staggered across the length of said first rod relative to said tines mounted to said second rod; and a ground brushing device having mounting means connected to said frame positioning said frame and said tines behind said ground brushing device as said ground brushing device is moved across ground. 12. A method of treating turf comprising: providing a frame to be moved across turf with said frame including a rod rotatably mounted thereto with said rod having a plurality of spring tines mounted thereon, said spring tines having bottom ends extending downwardly toward ground at an angle, said rod including an outer end with an arm fixedly mounted thereon; selecting a desired angle that said bottom ends extend toward ground depending upon the amount of desired combing of turf; pivoting said arm until said rod rotates to position said tines at s
