Warning - Danger

It is the user’s responsibility to insure that proper guarding is in place to compensate for the additional length. PTO shaft guard must be in place when using. Use of this adapter will lengthen the shaft. It is your responsibility to make allowance for adequate shielding. Check driveline to be certain it is short enough to compensate for added length. Straight drivelines are desirable. Excessive angularity runout of length may cause failure or injury. This product may result in a change of speed of the driven implement. Do not use this product if the result is an increase in the speed of the driven implement.
