TROUBLESHOOTING TOWING THE MACHINE Towing with a tractor of insufficient weight may cause ac- cidents! Perform towing using a machine weighing at least as much as the machine that you want to tow off. Towing to start the engine will damage the hydrostatic drive system! Do not give the machine a tow to start the engine. This will not start the engine, but may damage the hydrostatic drive system. To avoid damage to the hydrostatic drive system, do not tow the machine for more than 0,6 miles (1000 m). The towing speed must not exceed 1.2 mph (2 km/h). Perform towing using a machine weighing at least as much as the machine that you want to tow off.
Connect both machines with appropriate towing attachments. 75_023 Towing attachments fastened to inappropriate points may damage the machine! Only fasten the towing attachment to the points provided for this purpose. 1 2 At the front part of the machine, fasten the towing attachment at the marked eyes. At the rear part of the machine, fasten the tow- ing attachment at the hitch. 1 75_278 Before you tow a machine with a hydrostatic drive system, es- tablish a short-circuit connection between the high-pressure side and the low-pressure side of the variable pump. For this pur- pose, turn the high-pressure valves in the valve block about 2 revolutions. Proceed as follows: 5 4 3 1.
Set the driving-direction switch to position 'N'. 2. Loosen both screws (1) and remove the cover plate (2). 3. Remove protecting caps from the valves. 4. Hold the valve (3) in position, using a wrench. 5. Loosen the counter-nut (4) an re-insert the threaded stud (5) clockwise, using a hexagonal socket head wrench, until it reaches the top edge of the counter-nut (4). 6. Re-tighten firmly the counter-nut (4). Perform these opera- tions on both valves. 3 4 5 75_282 6-14
