i have about 100 acres of pine trees that i need to mow between, the 35 hp seems plenty big for that job..also will bemoving some dirt, building up some roads, box blading, etc...i keep reading that bigger is better and god knows that is probably true, but i have about committed to the L3400..local dealer is giving me a good deal...i will be using the jd lx5 for bushogging and a bushog brand 5 foot box blade, obviously the 4400 would give me more hp...45 ho vs the 35hp...i honestly will probably will only use it 3-4 times a year for big-time bushoggin', rest of the time moving dirt and levelling ground..i just don't feel that i need something bigger right now..but honestly the 3400 looked kind of small when comparing it to the bigger toys on the dealers lot...(maybe i already have bigger tractor envy which i hear is pretty common)....do i really need something bigger????? thanks in advance..this site and the info on it is great!!!!
