    Given the current prices in 2025, what are your thoughts on PT422 over PT425?

    Welcome bel422! A past member “fourteen” was a big fan of reversing many things PT related, the stump grinder being one. He turned the blade around and reversed the hoses so the chips flung forward. I’m not saying to do it! He swore by it. Kris

    Given the current prices in 2025, what are your thoughts on PT422 over PT425?

    If only 3.5 hours away…. That’s a no brainer! You’ve gotta go try em all! I believe when I bought my 425 it cost 10,500 vs 8,500 for the 422. I personally don’t know what I would do without the ROPS. What else would you hold onto?😂 That does seem to be quite a price difference between the two...

    Hydraulic oil change

    Thought I’d change the oil after eighteen years. Putting aside all the debate on motor oil vs hydraulic fluid. I ended up somewhere in between. Traveller branded utf from tractor supply. It’s a 10w30 viscosity and cheap. About $140 for 10 gallons. Turned out super easy. Hardest part was...

    422 will not stay in float

    I haven’t logged on in years! Boy I missed this place. Still loving my 425. I use to mow a lot with my 425 and I have what I call a “country” lawn. Mine would jump out of float as well….over bumps, so I installed what I called a float lock. It’s just a star knob with I believe 3/8-16 thread...

    Switched out robin to kohler

    About a month or so ago my robin 25 with 560 hrs died.... aside from the hard starts in winter every problem it gave me was in the rocker/lifter area, this one was no different. Upon disassembly I found the valve guide on the exhaust valve starter side of motor literally cracked in half. Must of...

    425 Robin Muffler Modification

    Just thought I'd post some pics of a mod I made last month. Bottom line, I'm really happy, but in hindsite, I really think it was fine the way it was. I mostly did this to satisfy my own curiosity. -Kris

    PT 425 mods

    Like some others have mentioned in the past my PT also jumps out of float when mowing. I mow a heavy 3 acres and the terrain is less than ideal. So I simply drilled and tapped a 5/16" hole precisely under the steel base of the joystick(when in the float position) and put a float lock knob. All...

    leaky lift cylinders?

    Hey guys, I feel like I might have a couple of leaky lift cylinders on a pt425 with 8 hours on it. It might be normal Im not sure but as the shaft slides in the cylinder oil pools up on the end. just out of curiosity does cold weather effect the seals or could this be a problem? Thanks Kris
