Hoses And Lines; Tow Vehicle Safety; Loading - Toro MH-400 Operator's Manual

For best results, use a tow vehicle with at least 45 hp and
four-wheel drive. A tow vehicle with less than 45 hp will
limit where you can go and how much payload you can
deliver. For example, a 27 hp tow vehicle can tow a fully
loaded MH-400 over flat terrain, but not on steep hills. A
four-wheel drive will also improve performance on hills.
With a smaller tow vehicle, you may need to reduce the
payload to 2 cubic meters (2.6 cubic yards) of material for
spreading in difficult terrain. Another option is to tow a
fully loaded MH-400 to a spot near the job and then load
smaller machines from the MH-400 to complete the job.
For best results, use a tow vehicle with a fixed
displacement hydraulic pump with a power output of 138
bar @ 38 L/min (2,000 psi @ 10 U.S. gal/min).
Performance will be reduced if pump output is less.
If your tow vehicle does not have hydraulics, you must
purchase the optional hydraulic power pack. This bolts
onto the MH-400 hitch tube and connects a drive line to
the tow vehicle's PTO (power take-off unit).

Hoses and Lines

Hydraulic hoses and lines may fail because of physical
damage, kinks, age, and exposure. Check the hoses and
lines regularly and replace them if required.
Fluid connections may loosen because of physical damage
and vibration. Check and tighten the connections regularly.
Fluid that escapes under high pressure may cause serious
injury. Disconnect the hydraulic or other lines to relieve
the pressure. Tighten the connections before applying
pressure.
: Protect your hands and body

from high-pressure fluids. Search for
hydraulic leaks with a piece of cardboard.
If an accident occurs, see a doctor immediately. Any fluid
that penetrates the skin must be removed by a doctor
within a few hours.

Tow Vehicle Safety

When fully loaded, the MH-400 can weigh up to 7,000 kg
(15,432 lb). Do not go beyond the limitations of the tow
vehicle.

: Ensure that the tow vehicle

has enough power and traction to pull a
full load. If not, reduce the size of loads.
The tow vehicle must have an adequate hitch and
functional brakes.
: The hitch tube is very heavy.
C
AUTION
Be careful when installing or removing it.
If an option is mounted on the rear, or the load has moved
to the rear, the MH-400 becomes heavier at the back. This
may create a negative tongue weight and diminished
traction for your tow vehicle.

Loading

You can load the MH-400 from the top or the rear. When
loading from the rear, raise or remove the rear gate.
: Ensure that the MH-400 is
W
ARNING
connected to the tow vehicle before
loading.
Do not carry loads that exceed the load limits of the
MH-400 or the tow vehicle (see Specifications on page 2).
The stability of loads can vary—for example, high loads
have a higher center of gravity. Reduce the maximum load
limits to ensure better stability, if necessary.
To avoid causing the MH-400 to tip over (see safety decals
on page 12):
•
Carefully monitor the height and weight of the load.
Higher and heavier loads can increase the risk of
tipping.
•
Distribute the load evenly, front to back and side to
side.
•
Be careful when turning and avoid unsafe maneuvers.
•
Always ensure that the MH-400 is connected to the
tow vehicle before loading.
: Do not put large or heavy objects into the
I
MPORTANT
hopper. This could damage the belt and rollers. Also
ensure that the load has a uniform texture. Small rocks
in sand can become projectiles.
