I know this kind of an old thread but I have a 1705 that i purchased new in 2016. I have around 750-800 hours on it. I use it for mowing, installing driveways, logging firewood for our wood stove, tilling, rotary mowing, and so on. I have not had any issues with it. A few things to consider.
When mowing there is a screen between radiator that needs pulled and blown off. It will run hot if its not done. Also the hydraulic filter is underneath the tractor so if are gonna be in the woods with it. You need to install a skid plate b/c if you puncture that filter. You will be screwed. It has happened to a few people. Part of the reason why I like doing my own maintenance. Just so i know where vulnerable items are.
