Opinions please. Previous owner put turf tread tires on our 425 (23 x 10.50-12)…hardly any tread wear but cracking in sidewalls, and a couple have slow leaks. Last time I bought a new tube for a lawn tractor (good brand I thought) it came apart real easily…new tires are quite expensive… Thoughts? 😊

On my Kohler CH25s, I have the analog SAM ignition… If a battery connection is loose (as in just put the cable end onto the post and pushed down slightly) can it cause an intermittent miss/stumble etc.? After much work on the motor recently I had just put the battery cables on, but forgot to...

MTD 5hp chipper shredder that I want to replace the motor with a new (but about 6 years old in box) Harbor Freight 6.5 hp motor. Best I can measure, I get 5/8” diameter shaft on the HF, but the original motor has a 7/8” diameter at the end of the tapered shaft. I’m seeing lots of adapters out...

My Kohler CH25s motor had a tag that listed the Spec number, but most of the label has worn away now… How else can I find out what my Spec number is?

In my last post, it was about getting in “tow mode” and about the engine quitting on bad gas, etc. So I was able to get it moved with the Bypass Hose installed. Got it home and ordered a new push rod for the bent one. Changed the oil and filter. Took the lifter out and bled it (it was solid as...

My PT425 was borrowed, taken out in the woods, and some bad gas was put in it…long story short, I need to get it back home where I can dig into the non-start problem now. So… I need to “tow” it—drag it up on a trailer. My manual says on way page that a “bypass hose” is to be hooked up between...

My 425 has developed an intermittent issue—running fine on level ground/road. Then when I hit a hill (especially my long, uphill paved driveway) it wants to bog down and sounds like the Kohler engine slows to the point of almost dying. If I let up on the pedal, or feather it some, then it seems...

My first time changing filter and fluid on our 425. Damn that filter is a beast to get to and loosen! I parked it where it was slightly leaning down towards the drain plug. Emptied it, removed filter, and put all new back. (I didn’t try and fill the filter seeing how it was such a pain to get in...

Our little older 425 sometimes loses pulling power—noticed it happens sometimes when I get a bucket of rock and bring it back up our fairly steep driveway. I’ll get about halfway and it slows down quite a bit, as I’m about to mash the pedal through the floor. I believe once it did come to a near...

I have a Briggs &Stratton Vanguard 6.5HP engine that the plastic carb float lost a sliver of material容nough that the needle valve falls through it. I致e talked with Briggs as well as countless others (even used) and always the same answer 登ut of stock and no idea when it would come available...
