Using the front receiver does anyone know what a reasonable towing capcity for the 422 or 425 would be. I have moved a 1200 pound trailer with about 1300 pounds of load on it with no problem. I wonder what the most anyone has "towed" or pushed and under what road conditions.

Thanks for any comments.

On level ground or pavement, you would be amazed at the load you could pull with the PT. It all depends on the grade, tire inflation, wet or dry ground.

I have a #7700 gross tandem axle enclosed utility trailer that I routinely move with my 422. The trailer is not normally loaded at gross weight, but on several occasions it has been very heavy, maybe #6000. The only problems I have had are the PT Pucker and seeing around the trailer. This trailer tongue weight is one of the main reasons I decided to load my tires with water/anti-freeze.

It is not the weight that causes the problems. It is the rolling resistance. When I worked at the airport I routinely moved large aircraft weighing in excess of 15,000 lbs with a hydraulically articulated lawn tractor that didn't weigh as much as the PT425. I could also push these across the tarmac by hand. I only weighed 135-150lbs in those years. There's no substitute for good wheel bearings. /forums/images/graemlins/grin.gif

Speaking of airports and moving aircraft. We would get a Boeing 320 (old days) that would be short of the gate by a foot or so. As long as the aircraft just arrived and had no time to develope flat spots on the tires, we would radio to release the brakes and one person could push the aircraft back the one foot. The ramp has a 3 degree back slope. Talk about wheel bearings.
Now how does this fit into the 425 pushing/pulling - it doesn't /forums/images/graemlins/grin.gif

Sure it does. PT offers an aircraft/trailer towing adapter for the 400 series units. Part # T3292, $275 /forums/images/graemlins/wink.gif

(Plus, it stokes our egos to say we can push large, multi engine aircraft by hand! (grunt grunt grrr) /forums/images/graemlins/tongue.gif /forums/images/graemlins/wink.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/cool.gif)

But can you stop them? I watched a fully-loaded KC-135R (an alert bird) jump the chocks once and "all the Kings horses" couldn't stop that puppy -- it rolled to the edge of the tarmac, despite 20 guys hanging on it, desperately trying to get a tug hooked up, and stopped when the nose gear sunk 30"-36" in the dirt...

Then, the fun part was two-fold:
1: Calling SAC HQ to tell them that we'd lost our alert aircraft
2. Off-loading 150,000 lb of fuel and using jacks to get it out of the dirt...

I have had to dig out more than one aircraft that came in hot and long. Overshot the runway and sunk in the mud.
Come to think of it, my 425 would probably have done very well getting it out. /forums/images/graemlins/wink.gif

I routinely move my boat in and out from the back of my garage from an outside parking place. There is some slope to the driveway. I estimate the whole works (minus tractor) weighs somewhere between 2500# and 3000#. The PT 425 never slips a wheel. In fact it will push it over the 2" "bump" into the garage from a dead stop but it takes full throttle to do that. I have not tried with it with a wet driveway.

One time I was working and an old Gulfstream G1 pulls in un-announced. I went out and directed them to park. The pilot started shutting things down and didn't set the brakes. The G1 started rolling backwards towards a fence and the pilot starts yelling to chock the wheels, chock the wheels!. I couldn't figure out why he didn't just use the brakes(maybe he didn't have any after he powered down). Anywho, there was a pile of chocks near the fence, so I grabbed THE BIG ONE(hey, it was a big plane, to me) and tossed it behind the left main gear. Plane stopped, tail dropped to within a few inches of the ground, nose wheel went skyward. Then it just sat there for a few seconds.... then went back down in front and bounced on the nose gear a few times. Pilot came out yelling and cursing at me. I told him to lump it and walked away. Then two limos pull up and a couple of young women dressed very party-like step out and walk up into the airplane. A few minutes later, they come back out escorting several members of the band YES. The guys are holding drinks and wiping the spills off their disco shirts with linen napkins. They had their Rod Stewart hair cuts, tight pants and big shoes and my mechanic and I were laughing so hard we were crying. After they left, the pilot appologized and said he had had a tough flight with some very picky passengers. We cleaned the interior of the plane for them and they gave us several unopened trays of catering food with meats, cheeses and shrimp, plus a cooler full of hot BBQ chicken that the band wouldn't touch. /forums/images/graemlins/tongue.gif
