Hello to all, I am impessed with the site so I thought I would tap into a great source of knowledge and wisdom. I am based in the UK and have just acquired a Ransomes 4000 (model no XT4010 s/n 00463) ride on mower fitted with a 3cyl Mitsubishi diesel (mid 1980s I think). It has Sauer-Sundstrand hydro transmision, 3 blade front mounted rotary cutting deck and comes with a front flail mower attachment. Whats left of the body decals say that it has diff lock and hydraulic weight transfer. The problem is that it has very little power to reverse drive, forward drive seems OK but I have not driven it far having only just got it. The hydraulic oil strainer in the tank filler neck looks as though it has been subjected to excessive heat. I would also like to know what oil is recommended for the hyd reservoir. Thanks in advance for any help. Nev.
