I have a ford 6000 tractor and I live in GUYANA. The hydraulic and brakes have been giving me problems. Firstly, the hydraulic leaked out all its oil whilst ploughing my rice field. This problem has since been fixed, but the hydraulic is lifting slowly -with or without plough. What can be the possible cause? Ever since, I got this tractor I noticed that the brakes were working on and off, that is- they would hold sometimes, and at other times they will not. What could be the possible cause? This tractor has one pump, which supplies the power steering mechanism, the hydraulic, and brakes with oil. What oil should I use in this tractor? Really need some advice. Where can I obtain spare parts for this tractor?
