9
9 Why should the driven speed of a PTO-driven implement be checked before attaching to the tractor?
Because the implement could be driven at the wrong speed
10
10 Why should the hydraulic pipe connections be cleaned before re-connecting to the implement and or tractor?
1, Because it prevents the contamination of the oil
11
11 What is the function of an "automatic pick up hitch"?

The PTO shaft will be at increased angle and may be damaged or fall
15
15 During work, the engine starts to overheat. Explain the danger if someone tries to remove the radiator or expansion tank cap.
Removing the radiator tank cap will cause the hot liquid inside to be released under pressure and could cause burns to the operator.

1. Trench edge collapse/shoring requirements
17

1. Do not park in front of entrances and exits
19
19 What speeds may PTO shafts be driven at?
540 and a 1000 rpm
20
20 a) Why should the body of the trailer be raised slowly/carefully when discharging wet or sticky material and b) What would be a consequence if this was not done?
a) The material could jam
21
21 a) Name THREE purposes of the raised treads on tyres and 4 b) What can happen to a dumper if the treads are severely worn?
a)1. Providing help when braking
22
22 Larger agricultural Tractors tend to have a turbo-charged engine a) What is the normal procedure before switching off the engine after working and b) What happens if the procedure is not followed?
a)Let the engine idle for a few minutes before switching off
23
23 Operators should lower the trailer fully before driving away. Give TWO possible consequences if this is not carried out?
1. The trailer could tip over sideways, especially on uneven ground
24
24 What is the purpose of the ROPS cab?
The purpose of ROPS is to provide protection in the eventuality of a rollover with the tractor
25
25 Which part of the shaft must PTO shaft guarding cover?

a)The transporter driver is responsible for the siding operation
28
28 If a higher operating speed (1000rpm) is selected for an implement designed to run at the lower speed (540 rpm), what may occur during operation?
The implement would over speed and may disintegrate causing possible damage and injury
29
29 On tractors equipped with power shift transmissions, manufacturers state that the parking brake is to be fully applied when parking and not just leaving the machine in gear. Explain why.
