"Having owned this tractor for only 8 months and 300 hours of work, it's too soon to draw conclusions as to value. Seems good so far. Except for the active seat. I found this impossible to live with on rough ground; works fine on billiard table smooth going. First attempts to disable it having failed I resorted to removing the ram, two connections only, and it works now as a normal air suspension seat. I don't anticipate reconnecting the ram after using it in this configuration for some time now."
