Pictures contained in this section are intended to be used as a visual aid to assist in explaining the operation of a Hay Tedder and are not necessarily of a HT419H.

Serious injury or death to the operator or others could result if the operator is under the influence of drugs or alcohol. (SG-27) HT419H 05/22 Operation Section 4-3 © 2022 Alamo Group Inc.
Page 52: Tractor Requirements
The power required to operate a implement is determined by the tractor PTO horsepower. For most operating conditions, the HT419H requires a tractor with at least 25hp. Operating the implement with a tractor that does not have adequate power may damage the tractor engine. Exceeding the recommended horsepower may cause damage by overpowering the unit in heavy operating conditions.
