Videos of New PT425 Arriving/Unloading

I don't understand why PT doesn't mount the engine backwards from that, with the exhaust manifold at the back, away from the hydraulic pumps. That would make the engine fan blow air out the back of the engine tub, which would keep underhood temperatures cooler.

Moving the exhaust manifold away from things like gas pmps, gas tanks, batteries, hydraulic pumps and lines would also help reliabilit issues.

The robin engines can have pumps mounted one either the front or the rear.

It seems to me that the 425 with the Robin engine is the simplest version to date, from a manufacturing standpoint. It's the most compact and has the fewest parts. Stacking pumps on one end is simpler and cheaper than stacking them on both ends.

The engineers and accountants made their choices. The product works really well in some respects, and not so well in others.

Balancing profitability and engineering sounds like exactly the job I don't want to do. I am really glad that somebody in Tazewell has been doing it for me.

My PT425 alternately frustrates and delights me. I'm OK with that. There are tractors out there that could do the job better, but I can't dream of affording them.

There are also better built affordable standard CUTs and SCUTs out there. My property is steep and rocky. If I had used them the way I use my PT, any one of them would have rolled over and crippled or killed me in the first week. I bought mine just before Thanksgiving/turkey hunting season 2004. I'm not dead or broke yet. I'm still here.

I'm wei(really unusual)rd. I'm really glad that those guys in Tazewell are willing to keep selling their weird tractors to guys like me instead of listening to the lawyers.

I'm sure that we could all come up with a consensus of functional improvements to the PT line. They will all cost money. Can we come up with improvements that will be more profitable and keep PT in business?

My Kohler engine has all of the pumps on one end. I think they make changes in order to make a good product at the cheapest price, and I think they are successful so far. They were real friendly when I took the tram valve to get it refurbished, talking to them is like talking to a neighbor and their show room has all the goodies to look at.

My 2001 model PT425 has the Kohler engine, the tram pump in front of the engine and the two PTO pumps behind the engine. The battery is in the rear. The muffler is a stock Kohler muffler on the rear of the engine and points out the back. The fuel tank it plastic and in the front. The hydraulic filter is kind of hard to get to, but not bad. To change the battery, you have to remove the muffler. My first battery went 6 years, though, so no big deal. And I can access the battery terminals for a jump start if needed without any problems.

To install pumps on both sides of the engine, they had to cut the fan shroud on the front, opposite of the shaft. It also required two pump mounts and two lovejoy connectors. By putting all the pumps in front of the motor, it saves them a pump mount, a lovejoy connector, the labor to modify the shroud, some bolts, some more labor, and it cuts down the hose lengths too.

However, you end up with a weird exhaust system.

By having the engine all the way in the back, more weight is on the rear wheels. My 2000 PT422 with pumps on both ends of the motor is very light in the rear. I always put about 100 pounds on the back, and it is really needed.

I have read that a few times and I have to wonder because when they move the engine back like that, they are moving the two PTO pumps forward AND they are putting the battery from the very back of the machine to a position way forward of the rear axles. I'll venture to say it is wash with weight distribution.

The pump behind the motor is pretty small. My other reason for saying this is that people with other pts don't seem to need the weight. A 100 lbs on the back of mine makes it a different machine.

Bob, I have the same machine as Moss, and I have all 4 wheels loaded with WW fluid (about 75 lbs or so, each), plus I had a weight box fabbed up for the back. I don't use it much, because I typically don't need it with the loaded tires.

Just saying...

Makes sense. Maybe all PT422s need the weight. I stand probably corrected. Can we weight the back of both machines? Mine is so non-stock it probably would not tell much.

Does the increased tire weight improve pushing or digging ability?
