speed and steering ranges without binding and linkages, loss of lubricants, grabbing, and
chattering or slippage when controls are applied to control, stop , and hold the vehicle
(see 4.6.5.3.1).
3.4.3.3 Speed. When tested in accordance with 4.6.5.3.2, the loader shall achieve a top
speed of not less than 10 miles per hour (mph) (16 kilometers per hour (km/h)) with the gear
selector in drive (D) position, and not less than 5 mph (8 km/h) with the gear selector in hilly (H)
position. The loader shall perform without malfunction or transmission shifting.
3.4.3.4 Creeping. When tested in accordance with 4.6.5.3.3, the loader shall be capable
of smooth creeping at speeds not to exceed 6 in. (15 cm) per second.
3.4.3.5 Acceleration. The loader shall be capable of accelerating from a standing start,
with engine at idle, to 10 mph (16 km/h) in not more than 45 seconds (see 4.6.5.3.4).
3.4.3.6 Turning. The loader shall be capable of turning to the right and to the left, in
forward or reverse, with the carrier remaining within a 40 foot (ft) (12 meter (m)) diameter circle
(see 4.6.5.3.5).
3.4.3.7 Braking.
3.4.3.7.1 Brake controls. With the brake control levers fully released or locked, the tops
of the brake lever handles shall be in alignment with each other within 0.5 in. (1.3 cm). The force
required to lock the brakes shall not vary between the two levers by more than 5 pounds-force
(lbf) (22 Newtons (N)). With each brake lever in fully locked position, there shall be at least
2 notches of travel remaining (see 4.6.5.3.6.1).
3.4.3.7.2 Brake lever turning force. When tested in accordance with 4.6.5.3.6.2, the
brake lever force necessary to start a turn at all temperatures down to 32 degrees Fahrenheit (°F)
(0 degrees Celsius (°C)), shall not be more than 40 lbf (180 N), and the lever force necessary to
hold the turn shall not be more than 30 lbf (130 N). The increase in lever force at all temperatures
between 32°F (0°C) and -65°F (-54°C) shall not exceed 20 percent.
3.4.3.7.3 Braking distance. When tested in accordance with 4.6.5.3.6.3, the loader shall
stop within 10 ft (3 m) from the point of brake application.
