While slopes and hillsides add aesthetics and dimension to the landscape, those same hills and slopes can be very dangerous to mow without the right type of slope mowing equipment. Ventrac tractors feature a low center of gravity and a wide stance to provide a safer solution for mowing slopes. An oscillating frame helps keep all four wheels in contact with the ground while an innovative weight transfer system improves traction and stability needed on hillsides.

Refer to applicable operator manuals for maximum angle of operation of equipment.

4500 Intermittent Use Defined

^ The engine may operate between 20° and 30° for up to 10 minutes. If 10 minutes is reached, the engine must be returned to 20° or less to assure proper oil lubrication. After returning to 20° or less, the intermittent cycle can be repeated. The 4500P Kawasaki DFI engine is rated for 30° continuous operation and does not have this requirement.

Operating On Slopes

Slopes can cause loss-of-control and tip-over accidents, which can result in severe injury or death.
Be familiar with the emergency parking brake, along with the tractor controls and their functions.
Use low range when operating on slopes greater than 15 degrees.
Never shift between high and low range while on a slope.
Always move the machine to level ground and place the selector lever in park before shifting range.
Variables such as wet surface and loose ground will reduce the degree of safety.
Do not drive where machine could lose traction or tip over.
Keep alert for hidden hazards in the terrain.
Stay away from drop-offs, ditches, and embankments.
Slow down before making sharp turns or operating on slopes.
Pulling loads on hills decreases safety.
It is the responsibility of the owner/operator to determine loads that can safely be controlled on slopes.
Transport machine with attachment lowered or close to the ground to improve stability.
While operating on slopes, drive in an up and down direction when possible.
If turning is necessary while driving across slopes, reduce speed and turn slowly in the downhill direction.
Ensure a sufficient supply of fuel for continuous operation. A minimum of one-half tank of fuel is recommended.
