Mower is massive, (600lbs). Assembly was pretty simple. Just a couple items to mention, regarding this mower. Mower came pre-filled with engine oil, but I had to add another 1/2 quart because it was low. I also ended up using 6 (smaller) tubes of grease to grease up the 4 tires and the height adjustment. I was quite surprised it took that much grease. You will also need to purchase a 12v U1 battery for the unit. However after all was installed and a little gas was added, the mower started right up after the first key turn.
