3.3 Tractor Horsepower

The horsepower required to operate the mower depends on many factors including the vegetation to be cut, terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the Grass king flail mower require a tractor with at least 90HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.

3.4 3-Point Hitch

The tractor 3-point hitch must be rated to lift at least 1720 lbs. when attaching a 62 “ Grass King flail and 1870 lbs. when attaching a 74” Grass King flail.

Grass King flail mowers can attach to tractors with a CAT I and CAT II hitch. Refer to the tractor operator’s manual for the category of the tractor used. If the hitch does not conform to ASAE CAT I or CAT II dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount nonconforming hitches.

Use the correct hitch pins for the hitch category being used. For a Cat I hitch, 7/8” lower and 3/4” upper diameter hitch pins are used and Cat II hitches require 1-1/8” lower and 1” upper diameter hitch pins. OPS-F-0036

3.5 Tractor Hydraulics

The Grass King Flail must use a tractor with 540 RPM PTO, single remote hydraulic connection and three-point hitch. NOTE: Remote hydraulic connection and three-point hitch must work at the same time. A four-bar folding linkage allows the single hydraulic cylinder to position the flail mower from 45° down for ditch bank trimming through 90° up for transport.

Maintain a minimum of 20% total tractor weight on the tractor front end at all times. Front end weight is critical to maintain steering ability and to prevent the front end from rearing up. Consult your authorized tractor dealer for front weights and carriers.
