The price of 8200 series tractors includes a pick-up hitch, but if this is not needed – and the less expensive clevis drawbar meets the customers needs – the cost saving covers the price of the TIC option and it is fitted free of charge. The cost of adding TIC in the factory to a new tractor equipped with the ELC and Datatronic units depends on the customers drawbar requirements.
#Automatic depth and draft control in tractor plus#
Extras needed on the tractor are the sensing pin, which works with a clevis type drawbar only, plus the electronic spool valve, and these are relatively inexpensive. MF8200 series tractors already equipped with the Datatronic information and control package plus Massey Fergusons Electronic Linkage Control (ELC) system are well on the way to working with TIC. When a correction is needed, an electronic spool valve on the back of the tractor operates a ram to adjust the depth control wheels on the implement, with a sensor on the implement to measure the height adjustment. The force is measured by a Bosch sensing pin inserted at the tractor end of the drawbar – changes due to variations in soil or working depth are signalled through to the Datatronic control system in the cab. The system works by measuring the draft force exerted by the implement as it is pulled through the soil. Advantages are claimed to be increased output and efficiency plus reduced fuel consumption. TIC is now offered as an option on MF8200 series tractors from 145hp upwards and will be used mainly with big disc harrows, cultivators and combination implements, says Massey Ferguson.
MFs Trailed Implement Control (TIC) system was launched at the end of last year, with the first tractors equipped with the system due to be working on UK farms later this year. Massey Ferguson has now taken the idea another step further with its TIC system which is designed to provide draft control for trailed implements. IT was Harry Ferguson who introduced the first form of automatic draft control for mounted implements when he developed his three-point linkage system.
