Tractor Requirements
The Model MDX71 disc mower is designed to fit trac-
tors with 540 RPM PTOs with standard ASAE Cate-
gory I three-point hitches.
The Models MDX81/91 disc mowers are designed to
fit tractors with 540 RPM PTOs with standard ASAE
category II three-point hitches.
The tractor must also have adjustable sway bars or
a means of locking the lower lift arms from moving
sideways.
For the MDX71 disc mower, the tractor front axle
weight should be 782 kg (1725 lbs.) or greater prior
to attaching the disc mower. This is for tractors with
a wheel base range of 78″ to 84″. Add additional
weight if required to achieve 782 kg (1725 lbs.) or
greater.
The tractor must also be equipped with one remote
hydraulic circuit with a minimum of 104 bar (1500
PSI) and a maximum of 193 bar (2800 PSI).
The tractor should be 45-horsepower minimum for
the Model MDX71, 55-horsepower minimum for the
Model MDX81, and 60-horsepower for the Model
MDX91. Insufficient tractor horsepower may cause
stripping and poor cutting.
The tractor must have adequate ballasting, wheel
spacing, and tire spacing to be stable on hillsides.
Too small a tractor may create a stability concern
when mowing in hilly conditions.
CAUTION
A tractor with an enclosed cab is recommended
when operating a rotary disc cutting machine.
