Pirate,
I'd recommend that you avail yourself of Ronald's services. He's a top notch mechanic who knows these machines inside and out, and he's dead honest, too. Hard to find all that in one person these days.
One more really big reason to go with Ronald's service is that he, along with just a couple of other dealers, freely shares his knowledge with us here on TBN and other tractor forums. Ronald, Tommy and Chip have dispensed tens, perhaps hundreds of thousands of dollars worth of advice for free on these forums, helping all of us with our tractor's problems.
Whenever there is something that I need and I can get it from Ronald or Tommy or Chip, you can bet I will go to them first, rather than second. Those guys deserve our custom since they give so freely of their time and expertise. I just bought a new loader valve kit from Ronald, in fact. Sure, I could have spent a dozen or more hours chasing down all the individual parts and put them together myself, and possibly have saved myself fifty or a hundred bucks - if everything went exactly right on the first try. Instead, I got Ronald's kit, with all the legwork done for me, and it took me about an hour to install it and it works perfectly. If I figure my time is worth anything at all, (and I darn well do), I actually saved money by getting the kit from Ronald.
So I say take your tractor to Ronald and you can feel confident that it will get excellent service and you'll get honest answers and a more than fair price. Why take a chance on someone you don't know about?
