I was almost to the point of purchasing the above mower, however, after reading the owners' manual on the said machine, I'm becoming very concerned that I may be purchasing a maintenance nightmare e.g. according to the manual all hydraulic lines should be replaced every 2 years. The GR2100 has a number of excellent features i.e. all wheel drive, glide steer, power steering/deck, which on my hilly/uneven property would be an advantage. However, if all of these features are likely to be maintenance nightmares I may be better off with a simpler, cruder machine i.e. John Deere LX280. If anyone could give me their thoughts and feedback on the maintenance possibilities of the Kubota GR2100, it would be extremely appreciated.
