Last fall I purchased a Husqvarna 4421Dxp HUV. It has a 20hp Kubota diesel engine. There is no low range due to a wide ratio transmission and the torque of the diesel. There is not switch or lever for the four wheel drive. It is handled my an automaticmechanical center differential. The axle differentials have automatic mechanical lockers to give true 4x4. The rated weight handling capacity1050 lbs. It has an electric driven screw type bed lift to give a hands free, powered dump bed. The frame is fully boxed aircraft grade aluminum.
Since my purchase I would test all these things to see if it really is as great as the advertising makes it seem.
The engine starts with help from an intake heating system to allow starting in cold weather. How cold? I managed to start mine at -10 F while hunting in Montana. The only problem was I had not put anti gel in the fuel and it took 1 1/2 hours to warm the fuel up enough that I could actually drive it anywhere.
Fuel consumption is estimated at 36 hours for one 6 gallon tank. I pushed it hard in the mountains. With the added elevation, plus running tire chains in fairly deep snow, it did impress me. I ran for 3 days without filling and then it only took 3.5 gallons. I only put fuel in it twice in two weeks. What the actual consumption was I do not know, but running to the same areas and back with my Polaris Sportsman 700 I used about four gallons per day on average.
I stacked as much firewood as I could in the back of and it hauled it with no problems, and was not bottomed out. Most of the wood was fairly green to I figure I had at least a 1000 lbs. The dump bed worked well to dump 5 loads with that much weight without straining. I also hauled myself, my father, two people in the back, two mule deer, and all our gear without even any noticable squat.
Speed is blazing 25 mph, but most places I use it you cannot even go that fast due to rought conditions. The ride isvery comfortable for the given weight capacity.
I have it to skid green pine logs up to 28" in diameter and 30 feet long. I am amazed at the pulling power. The added fact that the machinghas a dry weight of 1597lbs. helps with traction during pulling.
The four wheel drive system works flawlessly. I was skeptical at first, but I am now convinced they did it right.
The machine climbs steeper terrain than expected, goes through more mud with ease, and handles all offroad situations bette than I hoped for.
It has 4 wheel disk brakes that work great. I have yet to find a situation that I would rather have my 4 wheeler for other than narrow trails. The frame is built like a truck frame. There are full skid plates front to rear. The brush guard is built better than a lot of truck brush guards. It is very heavy duty and mounted to the frame. This thing is built like a tank, and I feel it is the best side by side vehicle for hard heavy use.
