SECTION 00 -- GENERAL INFORMATION -- CHAPTER 1
00-4
Tractor Requirements
The Model MD72 disc mower is designed to fit
tractors with 540 rpm PTOs with standard ASAE
Category I 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 MD72 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 inch to 84 inch. 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 MD72, 55-horsepower minimum for the
Model MD82, and 60-horsepower for the Model
MD92. 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.
WARNING
A tractor with an enclosed cab is recommended
when operating a rotary disc cutting machine.
Failure to comply could result in death or serious
injury.
