CK3510 1st gear grinding

Thanks Vince. Your DK 35 sounds a lot like the Ford 8N back on the farm. It ran 35+ years without a major issue - just points, plugs, oil changes and an occasional distributor cap and set of plug wires.

On any of these 600+ hours, did you ever noticed any grinding? That's what kills synchronizers. Either caused from shifting without the clutch or a improperly adjusted clutch.

There are lots of Kioti tractors here in Portugal. All geared transmissions as we don't do HST here. Most stacking well above 2,000 and 3,000 hours as they're used for comercial brush cutting, so pretty much daily use with probably hundreds and hundreds of direction and gear changes during the day.

Haven't heard any issues with synchronizers. Same applies to other tractors with the so called Korean engineering.

Wow! Great to have someone from 4K+ miles away to participate. Thanks PTSG!

Regarding having any gears grinding or other odd transmission behavior, the answer is no. I always used the clutch and never forced the tractor into gear.

As I mentioned above, I grew up on farm. I learned to drive on a Ford 8N and drove an Oliver 77 for many years bailing hay. Additionally, I had time on three Massey Fergusons - 235, 265, and Super 90. After I left home my Dad added a 2-85 White. I'd drive it on occasion for spring tilling. No issues with the transmissions driving any of those tractors.

I don't know if it's a contributing factor. Along with tilling, planting, and rotary cutting, I used my CK3510 to plow snow off my driveway. Some years it snows more than others, causing more winter hours. One winter, my wife and I cleaned up over a two dozen large willows and box elders that came down in a wind storm. That probably put 30+ hours of 0-20 degree F on the tractor. I skidded the trees and piled them with the loader into a large brush pile.

I mentioned the winter usage as that's when the transmission acted up, both times, while plowing snow. I attempting to shift from 2nd into R, when the transmission didn't want to come out of 2nd gear. Really startled me as I had never experience a tractor getting stuck in a gear. Sticking in 2nd and R became progressively worse. That led to the dealer replacing the synchronizer hubs and rings.

Similar, I was plowing snow when I shifted the tractor into 1st gear to scrape hard pack snow off of a concrete apron. I was in L or M range. When I left the clutch out the gears ground. Never have experienced that happening in the past either. It took me a while to discover, if I kept the range in neutral, shifted into 1st and released the clutch, and then depressed the clutch and selected the range, the transmission would work.

I'm glad to hear you've had no transmission issues with your tractors, that's fantastic! Hopefully I'll get mine figured out.

I have a 2013 LS 5030c ( Korean) with a Mitsubishi engine and have 1300 hrs on it with zero issues other than new battery 2 years ago. I am ashamed to say I have never changed the oil or filter in the Tran/ hyd system and works flawless. I change engine oil and filter annually using T6.Transmission oil still looks very clean but plan to change it and filter soon. Have not changed front axle oil either.I am sure to get disciplined about this but at 83 years my skin is pretty thick

LOL - Paul, thanks for sharing! Growing up on a farm, we were pretty good about changing tractor engine oil - annually at minimum. In the 60s and 70s, we ran straight 10 in the winter and 30 in the summer. Transmission fluid, much longer intervals between changes, likely 4+ years.

I’ve closely followed the maintenance intervals documented in Kioti’s owner’s manual. And I purchased the CK3510 shop manual, which provides a detailed maintenance schedule.

Kioti’s schedule for the CK3510 -
Manual Transmission Filter, change after 50 run hours and every 200 afterward
Manual Transmission Fluid, change after 400 run hours

All I know - something is amiss. I’ll be digging into the repair in a couple of weeks. I have to get the food plots tilled and planted before the tractor gets split.
