I have a Junior 36 that has been used for 3 seasons. The hour meter does not work, so my best guess is that I put 500 - 600 hours on it per season. It runs great. It does not burn oil or leak any. Oil is changed weekly. There is also no problem with the way the wheel motors run. The difference between this machine and the regular Junior and Intermediate is wheel base and hopper capacity. The wheel base is a couple of inches skinnier on this machine, so it fits through a 36" gate. The hopper only holds 110 pounds, but an extension piece can be added to give 220 pounds capacity of fertilizer. I am asking $4300.
