CK 20 Questions

[sschriber]

I've had my CK20 for almost a year, with about 35 hrs on it, and I have 2 questions perhaps you folks can help me with.

1- The loader looked a little crooked from the driver's position from the get go, but I attributed it to the optical illusion created by the brush guard being off. I loosened the guard a month or so ago and twisted it all the way in one direction and this seemmed to align closer to the center bar with the loader. Yesterday I parked the tractor on my reasoonably flat driveway and measured about 3/4" difference in the gap from one side of the bucket to the other. Is there a +/- spec to this bucket "parallelism" that is considered within tolerance? Is there a way to adjust this alignment? How do I check to see if I have one of the new loaders - post loader cracking fix?

2- I purchased a 3pt skidding winch (Uniforest 35E) and love it! One issue I have is that sometimes with a bigger log, the 3pt hydraulics can not raise the winch off of the ground. Per the ck20 specs, the lift capacity is 1100 lbs at 24 inches aft of links. The winch weighs 450lbs with a center of mass less than 10 inches aft. What should I expect the hitch to raise at a distance of 12" rear of link? Is there a way to test if the hydraulics are operating properly? Yesterday I notice one side was lifting more than the other... I thought the two links would lift in unison.

Thanks for any feedback.

Steve, I can't help you with question 2, but the old vs new loaders are easy to tell appart. On the 'new' loader the tube that runs between the loader arms goes through the arms and sticks out a little. The old loader that tube just goes into the arm but does not come out the other side. There are pictures of the different arms taken by HODAK here: http://www.tractorbynet.com/forums/kioti-owning-operating/104865-kl130-ck30-problem-4.html#post1198303

Typically, the lift capacity of a 3 point hitch at 24" behind the lift eyes is 70% of the capacity at the eyes.

If your "24" behind lift eyes" capacity is 1100, your "at the eyes" capacity would be about 1600. Since 12 inches behind the eyes is right in the middle of the 2 figures, and its a direct relationship, I would guess right around... ... 1350lbs, 12 inches behind the lift eyes.

Figure on losing 15% of capacity for every foot you go out from the lift eyes.

If you've had your tractor for almost a year then it is likely you have the old style loader. I don't think the new style showed up until about January 2007. The cracking issue is not likely related to the lack of level. It could be the loader (there is another report on TBN right now about this in a CK20 and there were a number of reports a year ago about Kubota B3030s). I haven't seen any technical discussion of how a loader could be "unlevel" but it doesn't seem to be an abuse issue especially since it seems to be reported mostly in fairly new tractors. I suspect you'll not get a straightforward answer from your dealer but you might as well bring it to his attention formally as you are getting near the end of your FEL warranty (one year).

Also, don't forget to check the air pressure in your front tires. Having one lower than the other could cause the FEL to be non level.

Thanks. Has anyone every noticed an "uneven" lift of the three pint hitch when there is a heavy load? How exactly does the hydraulic rotary lift work? Are the two arms independent?

One of the two arms is adjustable so you should be able to equalize the 3PT hitch to be level.

I have a grill guard and mine also looks "off" w/ respect to the loader when sitting in the seat. My loader looks lower on the right and higher on the left assuming the guard is perfect level. Or to think of it another way, the guard is tilted to the left and the loader is perfectly level. I could probably loosen the guard to make it match the loader crossbar.

You 3/4" gap difference you mention -- Is the the gap between the grill guard and loader cross-tube ??? i.e. the leftmost part of the grill guard measures 3/4" different from guard out forward to loader cross tube than the rightmost part of the grill guard?

Next time I'm out there I'll try to remember to measure up mine.

I have the old loader w/ torque tube re-enforcement cover installed and had to transfer the lock washer from one side to the other in order to get a little more clearance from the grill guard. The hex nut with the thickness of the lock washer was getting extremely close to the grill guard with the loader all the way down and lifting front tires off ground. The hex nuts are now about 3 or 4 mm closer to the torque tube cover w/ the lock washers on the bolt head side instead of the hex nut side giving me like a 3/8" gap instead of like less then 1/4". It's tight but it clears. I only had to do this on the two torque tube cover bolts that line up with the left and right "arms" of the grill guard. I check the bolts periodically to make sure they are all staying tight.

My loader may not be perfectly level, but it may be the blade of the bucket being bent a little in the center deceiving things (from rolling and straddling a rock when back blading -- front end came up and weight of tractor was on such a small area). On my garage floor which is quite level, the right-hand side of bucket makes contact just a tiny amount before the left side does... it's not off by much and the garage might not be perfect. My front tires are identical in pressure -- the rears seem alright (filled w/ salt water) and even w/ valve stem at the top, water comes out trying to check pressure, so I check by pounding on them at the top and they seem fairly uniform w/ matching footprints. I think my tires were filled on their side and that's why there's some water even w/ stem at the top.

I'll try to remember to take a picture perhaps too.

The 3/4 in difference is measured with the bucket in the neutral (indicator rod flush with tube) position and lowered until it is almost touching the pavement. From the driver's seat, the right side of the bucket will be 1 1/4 inches off the pavement while the left end is 1/2" off the pavement.

 

[malk315]

Oh -- I thought you were talking about distance from grill guard to loader torque tube. It sounds like you're talking about distance from bucket blade to level pavement at the extreme left and right hand sides of bucket.

Yep -- mine is off a bit, but I don't think as much as yours.

I'll try to measure tomorrow as I expect to have the tractor out at some point.

I'll try to take some pictures and post for comparison.

Make sure both rear tires are infated to the same pressure, this will definately alter the loader bucket from sitting flat on the ground.
The new loader model number ends with 'B' ie. KL120B, KL130B
