Now to repent for my mini-tirade of the 'delivery' experience.

First--some differences between Moss Road's PT425. I'm listing this as his is an earlier machine, and he's done a great job of documenting various aspects of the tractor.

-His has a plastic gas tank mounted in front of engine. Mine is steel and is a part of the cover, which places it above the engine and makes it hard to open the cover when full, and you can't easily tell what the fuel level is. Fuel could spill out, also, when opened. BUT, the battery is now where the fuel tank on MRoads machine is. Pretty convenient. Moss-Road--where is your battery???

-My engine mounting is reversed from MRoads. The exhaust is toward the front. Pictures to follow.

-The great debate regarding Command Pro vs. Command. Contrary to Scott's (Gentry) assurance that the Kohler 25 is a Command, the decal on it says Command Pro, it has the yellow cap, dipstick, oil sentry, oil cooler, etc. I think they just substituted the Command air filter for lower cost, and lower profile for the fuel tank that is now a part of the engine cover to clear it.

Other stuff--

There have been posts about the treadle sensitivity. It is sensitive, but my feet may have been made for Power-Tracs. By having a toe on each side of the treadle, modulation is easy, even on rough ground. It using just one foot at a time, smooth operation is difficult. Quick (and I mean QUICK!) stops are easy with one-toe at a time operation. /forums/images/graemlins/grin.gif

-Having the mini-hoe bucket curl as the separate lever is odd, but easily accommodated. I've read that some have considered relocating it or making a custom modification.

-I need to gain about 150 lbs. to use the generous seat belt! That's been well-documented in this forum. I have enough left over to make a shoulder belt. Hmm...

-ROPS seems sturday enough for the weight. Has anyone considered a separate ROPS for the rear part of the machine? There are holes in the bottom side plate behind the rear wheels. Just a thought.

-The exhaust routing and muffler insulation are interesting. I'll be cutting holes in the expanded metal where the dual exhausts (now comes out both side! More HP!. Woo-Hoo!) now spew INSIDE the engine compartment. Might have been better to slot the sides of the engine cover and extended pipes out.

-I haven't read the manual yet (Shame on me!), but the parking brake is counter-intuitive. That's why they couldn't figure it out at the freight terminal. RELEASING the brake seems to apply tension to the cables. I'm assuming that is to be a 'fail-safe' so the brake works even if cables part. I've discovered that it's very difficult to release the brake if the machine has drifted or been powered again whatever that mechanism is.

So--to make this not too long as I'm merely an owner, not an operator (or manual reader) at this point, I'll stop for now.

Pictures to follow.

The weather's better, the tractor's home, and will move to the property to do actual work within a week or two.

Since your machine is configured differently than mine, it may have a different air cleaner. However, if I understand Kohler's parts provisioning correctly (not easy), there are two different low profile air cleaners. The Command Pro's is slightly larger. That is what I have.

The brake pins are spring loaded. The friction brake lever holds them in the "release" position by pulling on the cables, as you found out. I think this is nothing more than a simple design. Since the brake is strictly a parking device and not an emergency device, I don't see "fail-safe" as being part of the design criteria.

The brake can certainly be difficult to release if any pressure has built up on the pins. The trick is to rock the tramming pedals ever so slightly while applying pressure to the brake handle. You soon learn to anticipate which pedal to use.

Snowridge--

Thanks for the reply!

I appreciate the info.--all of us together might know what we're talking about.

By 'fail-safe', I meant fail-safe as in parking, not a service brake. The scenario (given my luck and skewed way of doing most things) that comes to mind is that if the cable fails, the machine will be immobilized rather than being able to drift.

Regarding the Kohler method - two of the local shops here are more baffled than I am about what is what. Apparently there are a lot of variations depending upon spec and serial #.

Not sure if that's continuous improvement or a 'dang, we should have done that different' revelation.

Mark,

Congrats, and welcome to the PT family!

I am fairly confident you scored a "PRO" - you can check the spark plugs if you really want to - the PRO has different plugs.

As for me, given SnowRidge's experience (which he is really being a sport about), I would switch to synthetic oil (I'm using Mobil 1 10-30W) as soon as I could - I am also looking at putting oil pressure and cylinder head temp gauges in, as you can tell from another thread here.

Enjoy your new best friend and handyman!

Sincerely,

Rob /forums/images/graemlins/grin.gif

Is there a difference? /forums/images/graemlins/smile.gif

I'm going strictly by recollection and haven't looked at old posts, but it sounds as if PT cured a couple of problems/complaints. There were some posts about the battery being close to the exhaust, and the top of the battery getting hot. First, a new double exhaust reduced the heat. Now, it sounds as if the battery and exhaust aren't close any more, and the exhaust is still the PT type rather than original Kohler.

Charlie -

I asked Terry about this a few months ago when the new design came out. I think PJ got the first one. Anyway - he said that the exhaust is still only a 'single' exhaust, and the other 'hole' is for air INTAKE. I'm just repeating what he said. From what I can tell, this is the same exhaust as on my 425, and I can definitely say that the exhaust only seems to come out one side.

As far as I know, I get exhaust out both holes. I'll check as soon as I get the engine back and installed--whenever that is. /forums/images/graemlins/frown.gif

I do know for certain the muffler gets hot enough to torch off dry grass clippings. /forums/images/graemlins/crazy.gif We always check for this whenever we shutdown.

Rob: You're right, of course. I should have been more careful. As I understand it, the system that was installed starting in the fall of '02 is intended to have fresh air in one side and out the other with the exhaust, which keeps the outer shell cooler. I don't know if the new one is the same.

Mark,

Sorry to hear about the various trials and tribulations regarding the arrival of your new PT.

I only had one pallet to pick up from OverNight a few weeks ago, and it went very smoothly (of course I flew from Denver to NY and drove a rental truck back over 3 1/2 days to get my "new" PT to Denver, then dropped it off in Golden Friday afternoon during the snow storm, then drove back on Sunday to bring it the last 40 miles home after letting our mud county road dry out a bit.)

Looks like there were a number of seemingly needless frustrating issues associated with your new arrival. Hope that is all behind you now.

I also can not comment about the various differences between your 'latest-and-greatest' and the previous 'latest-and-greatest' versions of the 425, but it seems PT has generally made bigger steps forward than backward with each update. They also seem to make running changes as soon as they develop them rather than wait for new "model" years to come around. That is a good thing.

Glad to hear you are beginning to get comfortable with the operation and articulated steering and hydro system. I am sure your projects have been stacking up for a while so you will be putting it to good use right away.

Take a look at their recent price increases to cheer you up a bit. Just don't get run over out on 105 or 115!

Charlie,

I, too, am going from recollection (a scary thought), but I think another complaint about the old battery location was the need to remove the muffler in order to acces or remove the battery. This in addition to the heat factor you mentioned. As always, I may be wrong.

Rip--

Thanks for the encouragement.

Things look better today. As I mentioned in previous posts, a pessimist (that's me) is seldom disappointed and sometimes pleasantly surprised!

I will be about two weeks until I get the PT up to Larkspur as I'm currently in week 2.5 of the alleged 24 hour period for approval from the powers-that-be to install a driveway on my property.

It's hard to stay mad at a tractor that my wife thinks is CUTE. A little embarassing, but we agree on its usefulness.

That has not always been the case with equipment purchases over the last 20 plus years! /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

See add'l. posts for some pictures of the newest.

Regards
Mark H.

Congratulations on your new purchase, but sorry to hear of your problems. I think you will be pleased with your machine once you get to use it some after the problems are solved.
 
/ Now the good and some differences #13  
Something else you might want to take a look at look directly below the filler cap for the gas on the 425 , the exhaust pipe is directly below it. When I fill mine up I raise the hood, gets the tank away from the exhaust, but it is best not to fill it up when the machine is hot. If you try to fill it up with the hood down while it is hot and accidently spill a little it will light up your life in a very bad way. I think it is easier to fill up with the hood raised, at least on mine unless they have made other changes to the tank since I bought mine. It would have helped if the cap was to one side i beleive. Something else that I noticed on some of the pictures of some of your machines some of you have mounted the fire extinguisher to the hood, I mounted mine to the left rop bar. I beleive that if you had a fire on the machine it would probably be in the back of the machine and if flames were shooting out from under the hood you might not be able to get to your fireextinguisher just a thought.

<font color="blue"> Moss-Road--where is your battery??? </font>

In the right-rear corner of the engine compartment, under the muffler. The muffler has to be removed to get it out. I like your design, better.

Another difference is, correct me if I'm wrong, all the hydraulic pumps are now in front of the engine, where as, mine has the variable volume pump in front of the engine and the two PTO pumps behind the engine.

I'm a big boy, 6' and fluctuating often between 205 and 218 depending on how much chocolate I eat. That seat belt has never been too small! /forums/images/graemlins/tongue.gif /forums/images/graemlins/tongue.gif /forums/images/graemlins/tongue.gif Quite generous, indeed.

As others have mentioned, the parking brake can be kind of quirky. When I set it, I then step on the treadle pedal until I see the pins pop in. To take it off I jsut use the pedals and steering wheel to release any torque lock that might have occurred. You ever park a car on a steep hill and not been able to get it out of park?

Sorry to hear of your first day problems. I'll reply over there.

Thereby cutting down on the number of hours you can run the machine. That's a drag.

</font><font color="blue" class="small">( It would have helped if the cap was to one side i beleive. )</font>

I honestly can't understand why the cap is in the middle. My lawn tractor is like that and it's a pain to lift a full 5-gallon gas can to a point where you can refuel and not spill anything. I attached a flex spout with an on/off valve to help. But it's still a dumb design. Coupled with a gas tank that is mounted to the engine cover and I've just got to wonder how they dream up some of these so-called improvements.

I'd prefer a white plastic gas tank with the opening on the side and free from the engine cover. That way you can see how much gas you have and you can refuel without fear of blowing up and you can lift the engine cover more easily and without having to worry that gas might seep out of the gas cap...I assume this is a breather cap.

I also have the new design PT-425 with the gas tank on top. The tank can be filled quickly and safely by using a large funnel!! Mine is 10" round and 8" high. The lower part is small enough to fit tightly inside the gas tank opening, while extending about 3" into the tank.
Gas from a 5 gallon can may be poured full stream into the funnel without splashing or leaking onto the engine cover. When the open hole in the lower end of the funnel closes and begins filling with gas, it is time to slow the flow. Another inch or so and the tank is full!! Remove the funnel, replace the cap, and you are good to go!!!

PS: My funnel is red, which looks nice on my white engine cover while I am refueling!!

/ Now the good and some differences #17  
The cap is to the front edge of the tank, which is at the top of the tank when the hood is raised, thus preventing fuel from spilling when the tank is full and the hood raised. I think a real good idea!
 
/ Now the good and some differences #18  
I have a large red funnel, too. Mine also has a screen at the bottom of the funnel. I have the older plastic tank model.
 
/ Now the good and some differences #19  
/forums/images/graemlins/mad.gifYou're too lucky!! You have both a white plastic gas tank and a big red funnel!! That's not fair!! You should give one or the other to toolz_not_toyz!! Apparently he doesn't have either one!!!! /forums/images/graemlins/frown.gif

I have an orange funnel with a nice filter in it. I do like looking back to see how much gas is left (when really working hard, it does eat more gas), and I like the fact that condensation will not cause any rust! No offense, I like aspects of the new design as well. Having the battery away from heat and closer to the operator is nice.
