I recently purchased an Iseki RU 1400 compact tractor from a private individual. I did not receive an operators manual. On the left of the seat there is a lever that acts like a low range. When this lever is moved to central position the it appears to be netural. In either partial up, all up or down the clutch the cluch does not seem to be working.... Can anyone give me the general operations for the PTO lever, low range, 4 wheel drive, .... for this type tractor.
