Re FEL lift capasity. ASK if the lift is measured at the bucket pins(looks good ,but artificial) or at 18' (approx front of bucket and REAL WORLD accurate lift numbers)
Old tractors like Ford 2000/3000 and MF 135 have small hydraulic pumps and slooww loader lift.Also low lift capasity. Very easy to work on.
Kubota in narrow track are very tippy, if you have wide enough trails/gates I recommend you widen the track for sideways stability. NOTE some tractors have 1 piece rims and don't adjust and others will have 2 piece rims to allow track adjust ment. Makes a surprising amount of difference.
