Transporting manure over hilly farm for application

I have a 9 acre farm in western ghats, and the terrain is hilly. we apply about 10 tons of organic pressmud based manure. this is done as 2 applications of 5 ton each pre and post monsoon times. the mixing of manure takes place at the middle of the slope and after mixing with bio fertilizers and soil conditioners each batch would be about 5.3 tons. currently this manure is hand carried along the slopes for application and is very torturous. Kindly let me know if any one has implemented a suitable transport mechanism where the fertilizer can be placed at different points for easy application. any excavation and levelling of land gets totally lost due to heavy rains. Thanks in advance
