You mention, " I do have to run hydraulic lines for the front end loader (1200.00 ish dollars).. The dealer is telling me I might have to bite the bullet and buy a Woods loader since not many people make ones to fit this tractor?"
Looks like you, at this point, do not have a loader so the $1200 you mention would be included in the Woods (or whatever brand) loader you purchase.
However, if you buy a new loader you will probably pay more for it then you just paid for your tractor.
You bought the tractor at a bargain!
If you were at the dealer looking/asking about a loader he was only trying to get you spooked so you'd buy a tractor with a loader already mounted from him. He was playing you like a fiddle, but you got out of there in time!
The tractor you bought will do what you need. A diesel tractor can not be compared to what ever you owned previously that was same HP gas. You have 21 engine HP. You back up to a 21 HP gas lawn mower and hook the rear ends to each other....you can drag the gas around the section and never know it's there. Quit worrying.
PTO HP is 16, engine is 21. click here for more info.
