OPERATION
3.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
990 lbs.if attaching a HYDRO 88 & 96 flail.
SHD mowers can attach to tractor’s with either a
CAT I or 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 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 can 3/4”
upper diameter hitch pins are used and CAT II
hitches require 1-1/8” lower and 1” upper diameter
hitch pins.

3.5 Front End Weight
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.
3.6 Power Take Off (PTO)
Only operate the mower on a tractor equipped to operate at 540 rpm PTO speed. Tractors operating at 540
rpm will have a 1-3/8” diameter 6-spline PTO shaft stub. Refer to the tractor operator’s manual for operating
the PTO at the proper speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-
running clutch must be used between the PTO output shaft and the driveline of the mower. Consult an
authorized tractor dealer to purchase and install an over-running clutch if needed.
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
