On my PT-425, in 600 Hours of operation:
10 minutes maintenance per 8 hours operation.
(Lube and spray lube)
Additional 30 minutes maintenance per 50 hours operation.
(Engine oil and filter change, hydraulic filter change)
Minor repair and adjustment due to operator errors, about 6 hours
Repair due to bad design & broken parts that resulted (rollover), about 4 hours
Replacement of wear items (Tires, rubber plow lip) about 4 hours
So, "normal" and "routine" maintenance was 16.5 hours for 600 hours of operation, was 2.75%.
"Abnormal" and "non-routine" maintenance and replacement of wear items was 1.3%.
Total maintenance time was therefore just over 4% of operation time.
Wonder why I complained so much about the tractor in the forums?
Guess I'll count my blessings!
