So I looked around at all my options, including a new JD LT, and I decided to repower my GT225. The reasons are; First, it has a Tuff Torq K71B hydro transaxle, and they are rock solid. Second is that I know it like the back of my hand and that would not be the case with a new/used machine. The third reason is that this is not a winter machine (I have one heck of a snowblower for those needs.) and I do not have a vegetable garden, so I do not need fancy hydraulics. Finally, I am rebuilding the steering and by the time I am done with that and the repower I will virtually have a new (GT235) machine for @ $1K...not to mention the fact that I should be able to sell the Kohler 15HP easily for a hundred bucks or so. I'll post pics of the repower and the steering rebuild. Future plans include a 48" deck, a JD cart, a JD sweeper, and a JD bagger. I'll also be keeping my eye out for a Tuff Torq K71C with a locking differential. I understand that is a direct swap with some linkage routing.
