2.3 Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the BH114 mower requires a tractor with at least 15 HP, the BH115 at least 20 HP and the BH116 at least
25 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
Exceeding recommended HP may cause mower damage by overpowering the unit in heavy cutting conditions.
2.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at
least 393 lbs for BH114, 491 lbs for BH115 and 577
lbs for BH116. The BH114, BH115, BH116 mowers
are designed to be mounted on a tractor with a CAT I
3-Point hitch. Refer to the tractor operator’s manual
for the category of the tractor being used. If the hitch
does not conform to ASABE CAT I dimensions,
the mower may not fit or raise properly. Consult an
authorized
dealer
for
possible
modification
procedures to mount non-conforming hitches.
Depending on the hitch category, certain size pins
are used to attach the mower to the tractor. CAT I
hitches require 7/8” lower and 3/4” upper diameter
hitch pins.
2.5 Power Take Off (PTO)
This mower is designed to operate at a PTO speed of 540. Most tractors operate at either 540, or a
combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be
determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM
will have a 6-spline shaft and those operating at 1000 RPM will have a 20 or 21-spline shaft.
NOTE:
The mower will not operate on tractors equipped with a 1000 RPM 21-spline or 1000 RPM 20-spline, 1-
3/4” shaft.
Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more
than one 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. An authorized
tractor dealer can provide the over-running clutch and its installation 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.
