  • Big help!
Bought this for my 2025 John Deere 3046R. Works great and love the easy hook up of three point equipment. Paired with the I-match hitch. Lots cheaper than the dealer and works great!!

  • Zero for two,
I’m on my second cylinder in a week, both cylinders failed to extend, confirmed that the fault in both is the check-valve, removed the check valve and the cylinder operates properly. I wonder how many it will take before I get one that works! I only need one that works. Perhaps if they would send a half a dozen check valves I could find one that works. Duane Gamm ... show more

  • Works well with minor mod on Kioti CK4020SE HST tractor
Absolutely recommend a Hydrolic top link - it will simplify your tractoring days. I noticed from other similar products others commented the pivot socket where the pin connects to the rear of the tractor for some model tractors required the socket eye to be ground down on each side to fit within the bracket/clevis of certain tractors. I have a 2024 Kioti CK4020SE HST and needed to take down each side of the socket eye with a belt sander (Only took a few minutes - go slow and only take off enough to clear your clevis) in order to get this to fit. Once done it fits well and functions as expected. On an estimate I removed 1/16" from each side of the socket Eye on the end attaching to the tractor clevis. I did not have to touch the extension eye connecting to the implements. I attached the fixed eye to the tractor. ... show more

If you remember to fit a 1/32" flow restrictor. Otherwise it operates uncontrollably fast.

  • Wasn't machined correctly.
Hooked everything up and cylinder would extend but not retract. Tried flipped the hoses around,and no change. Tore cylinder check valve block apart and noticed the check valve plunger that goes back and forth wasn't the same size on each end. One side was 0.40 shorter,so it wasn't engaging the check valve correctly. I added a bead of weld and ground down to match the other side. It worked great after that. So be cautious of that. ... show more

Good solid cylinder, only had to buy adapters to fit the hose connection ends x 3/8 npt for couplers. Price is good. I tried to add a picture, didn't work on this review.
