The trailer didn't have the mowers in it. But even without them I have a pretty large bench across the front inside along with a little wonder blower and lots of extra parts and tools mower blades safety gear etc ... My best guess is probably 500 pounds maybe a little more or less. The registration shows the empty weight of the trailer at 3400. There's at least 800 lbs in the trailer. ..Most up front. .
I used my ventrac this weekend to pull around my 18 foot 10k utility trailer.. This one weighs around 2100 pounds pulls it like nothing even though it was sitting for 3 yrs, it grunted for a second and then pulled it right out ..
