The purpose of these guidelines is to help reduce the risk of injuries and fatalities by providing practical guidance on how to manage various tractor hazards. ACKNOWLEDGEMENTS This guideline was prepared by WorkSafe New Zealand (WorkSafe NZ), with representatives from: >> Accident Compensation Corporation (ACC) >> Ministry for Primary Industries >> Beef and Lamb New Zealand >> New Zealand Council of Trade Unions (NZCTU) >> DairyNZ >> New Zealand Dairy Workers Union >> Dairy Women’s Network >> New Zealand Transport Agency (NZTA) >> FarmSafe >> Primary Industry Training Organisation >> Federated Farmers of New Zealand Inc >> Rural Contractors New Zealand >> Horticulture New Zealand >> Rural Women New Zealand Inc >> Landcorp Farming Limited >> University of Auckland >> Lincoln University >> University of Otago.

SECTION 2.0 // HAZARDS AND CONTROLS The most common hazards faced by tractor operators are set out on the following pages. Guidance is provided about ways to effectively control those hazards. 2.1 PASSENGERS 2.2 GETTING ON AND OFF THE TRACTOR Passengers riding on tractors, tractor implements or trailers are at a high risk of The most common tractor injuries happen injury. Tractors travel over uneven ground when people get off the tractor. These happen and passengers can easily be jolted, lose when people slip and fall to the ground their grip and fall. If someone falls under or jump down and land heavily on uneven the wheels or into trailed machinery, they ground. If the driver gets off facing away from can be seriously hurt or die. the tractor, their pant cuffs or boot loops can snag, tripping them forward off the tractor. MANAGING THE HAZARD: MANAGING THE HAZARD: Do not carry passengers on tractors without instructor seats, roll-over When climbing on and off a tractor, always protective structures (ROPS) and keep three points of contact (eg two safety belts. hands and one foot) with the tractor or ground. Get off facing towards the tractor, the same as you do when getting on. Most older tractors are not designed to carry Never jump on or off a moving tractor. passengers. You can carry a passenger if the tractor is fitted with ROPS, cabs, an instructor seat and safety belt. 2 Do not carry passengers on tractor- mounted implements or trailers that 1 are not designed to carry people. Some types of trailed machinery, like ridgers, are designed for people to ride on and operate. Passengers can ride on this type of implement if the machinery is safe and well-kept. You can carry passengers on a transport tray mounted to the tractor’s three-point linkage. Tell the passengers to hold on. 3 Figure 1: Getting on or off with three points of contact 7

GOOD PRACTICE GUIDELINES // SAFE USE OF TRACTORS ON FARMS Tractors work hard and wear out. Brakes, steering and tyres – all critical to the tractor’s safety – are particularly prone to wear. Accidents happen when tractor maintenance is delayed beyond the manufacturer’s specifications. This puts operators at greater risk and increases costs through replacing parts and components, or causing business interruptions and breakdowns. Trying to repair a tractor in the field is also hazardous. 5.1 HOW TO MAINTAIN SAFE PRACTICE DURING TRACTOR THE TRACTOR MAINTENANCE: Tractors need regular maintenance. It must 1.

Disconnect the battery You are likely to get a better price for it too! Remove the key and, if practical, disable the tractor by disconnecting the battery to 5.2 WHAT MAINTENANCE? make sure the tractor cannot accidentally start during maintenance. Keep your tractor maintenance up-to-date. Even small things, like mud and dirt, build up on the cab floor and get under the pedals. A brake pedal depressing onto five centimetres of caked dirt is a pedal that has five centimetres less travel. If guards or protective covers have to be removed for maintenance, attach them to the tractor with a lanyard so they don’t get lost, and re-attach them correctly. 26
