Well received the unit Saturday. The delivery person knew nothing about the tractor. He actually told me to read the manuals. Was a little overwhelmed at the size and the amount of equipment I purchased and the weight & size of it all. After he left it was time to play. Removed 8 stumps with relative ease. However, the dealer sold my 18 bucket so gave me a 24 It is nice but is almost two big. I came to terms with the dealer that he will sell me a 12 at cost. Then it was time to see if I could climb the mountain. Well it did not. So I was a bit upset. Just would spin and not get any tractions.(keep in mind it did rain Friday) Seemed like the tractor was to light in front. So Sunday came and I decided to read the 448 instructions on how to remove to see if the tractor could climb the mountain without the 448 backhoe on it. Well I could not get the 448 off, after 2 hours. So Monday I called dealer and spoke with them and they actually told me not to follow the manual it was incorrect. I followed their procedure and within 5 minutes it was off. I then attempted to climb the mountain, no problem.
As far as the tractor and performance go wow way more than enough power. You can leave the rpm痴 down and still climb where everywhere you need to. There is a design flaw in the ROP痴, in that you cannot lower it completely (only have a 8 foot door on barn) when the Backhoe is on. During the swing down it hits the two control levers for operating the bucket. The fit and trim is night and day different then my Kubota. How JD recesses the zirc fittings, the gauge of steel, etc. Have a little over 9 hours on it and just last night hit セ of a tank. Have not used the brush hog, or the box blade.
P.S. have used the new JD lx140 mower what a let down in JD quality, and way too many safety features.
