I have just purchased a 20 acre lot of which about 4 acres needs mowing the rest is forest. I have someone willing to sell me a dixon 4421 that is 11 years old. looks good from my vantage point but I am no expert. He wants $850. Could use some advice on this type for a fairly flat 4 acre place with some trees on 1 acre of the place. He wants to sell the tractor as well if you know anyone that can help there. I appreciate any help.
