Strengths rNice turning radius. CLean burning engoine. good mower

Weaknesses Mower deck wont lift high enough. Sheared off mounting bolt going over pole barn threshold. Air seat is a cheapy version of the one they make on the AG tractors but they charge the same thing for it....about 500 bucks. Its practically worthless as an option.

Overall Much better than the JD Yanmar 4115 I traded in to get the 3720. I own (and have owned) US Made JD's. Why they chose to get into bed with Yanmar is a mystery to me. While the 3720 is a huge improvement over the 4115, it is still beneath JD's standards when compared with the machines they make here.

Strengths My 3720 I love I have had two JD tractors and this is one of the best My 4200 was replced by this one and I could never be happier. This tractor 3720 has more power than you need and is macthed well to the body of the tractor. The cab inside was well laid out.

Weaknesses The only weakness I seen was the AC at time would get stopped up after long use. But after a little cleaning of the filter it was in top shape.

Overall Overall their are NO tractor that can compete with JD I have tried other and found that green is mean. And when it come to resale your green will come back. ALL in ALL John Deere is the best tractor out their and that is that!
