I have a bull dog type hitch with a pin lock that prevents the hitch from being opened. However, nothing you put over the hitch will prevent a determined thief from just chaining it to a ball hitch, cranking up the tongue and dragging it away. Even if you chained the thing to the ground they's jsut cut the chain. If you left it hooked up to your truck, they'd steal the truck. For that reason, I never leave my tractor on my trailer overnight because it is just so easy with the quick attach to just unload all the implements and take them in the garage. After a long day of work, I just back into my driveway, unchain the PT and all implements, pop on the ramps, take the spare gas can in the garage, fire up the PT and unload all the implements into the garage, then park and unhook the trailer from the van. From the time I get into the driveway until the time I'm washing up for dinner it usually takes me about 20 minutes.
... which brings up another plug for a pickup truck, a trailer and a Power Trac.
Let's say you're a contractor with one conventional tractor...
You need your FEL to move some material. CHECK
You need your BOX blade to level that material. CHECK
You need your tiller to prep a seed bed. CRUD, have to switch 3pt implements.
You need your brush hog to clear some overgrowth. CRUD.
You need your forks. Maybe they'll fit on the FEL.
You need your trencher. CRUD!!
You need your backhoe to dig out a drain. CRUD again!!!
You need your post hole digger to put in a flagpole. CRUD! CRUD! CRUD!













No one in their right mind would attempt all those implement changes on a 3pt hitch tractor in one day. They just wouldn't do it. PERIOD!
Bring in the Power Trac....
FEL with two buckets, one being a grapple or four in one. CHECK!
Box blade. CHECK!
Tiller. CHECK!
Brush hog. CHECK!
Forks. CHECK!
Trencher. CHECK!
Backhoe. Mini hoe will do fine. CHECK!
Post hole digger. CHECK!
9 implements, any of which could be changed in 30 seconds or less. Even if it took a minute, that's less than 10 minutes to change 9 implements. And you can switch back and forth all day, at any time you need with no fear of bashing knuckles, straining your back, etc...
I would think PT on a trailer loaded up with implemetns would be a landscape contractors dream.
