FEL question

antifreeze will work. Some add windshield washer fluid

Because I am gone for 30 to 40 days at a time I was concerned that water might freeze and blow the tires or something to that effect. I have filled them before with an attachment made for that sort of thing that I have. It was cheaper to buy the cement than the antifreeze. I was considering putting water in the tires along with the weights to see how it performs next spring, but I 'm not sure how much of a stain it would put on the drive train or other internal parts.

Just wondering. Why do you need so much weight ? Do the rears spin that much ? looks like you have the rice tires on the rear.. I filled my rears once just so see what effect it would have. The only thing I noticed was, that I seemed to have some power loss due to the xtra weight

Hey Kenmac,

As long as I am on level ground there is no problem. But when I scoop up dirt or pick up a large log and have to back up an incline the back tires will loose traction.(this happens because of close quarter maneuvering due to the trees that I am systematically getting rid of) I am quite happy with the added weight as it allows me to push and pull much more effectively(fallen trees and stumps) with the box blade. The only time I notice any power loss is when in high gear on the gravel road, going up an incline. And even then it is minimal. I am usually in low gear when working so have never noticed any loss of power. The little yanmar is an animal!!!

Hey guys,

I installed a front end loader on my ym2000 about 1 1/2 months ago and was wondering if a particular trait is normal. When lifting or lowering to full height everything is normal, and even when tilting the bucket downward, nothing unusual happens. When I tilt the bucket from down to up, like when scooping up dirt or such, it lugs the engine, even with the bucket empty. And it just seems weak when compared to the actual lifting capability of the unit as a whole. It doesn't do it bad it is just a noticeable change in engine rpm and I have no idea if this is normal or not. At no other time, whether at idle or higher, does the engine change rpm during "normal" operation of the fel, just when tilting the bucket from down to up. At higher rpm it doesn't happen because of the higher pressure involved I just don't know if it should do it at all.

Another example, when scooping a load of dirt from a packed pile, I can drive into the pile of dirt, but the bucket will not tilt upward to break it from the rest of the pile. I have to lift the entire unit first, then curl the bucket. Any info from will be greatly appreciated and thanks for your time.

Love the Markham toothbar I put on the other day. Great people to do business with and for what it is worth, I highly recommend them to anyone considering this attatchment. It is very well made.

It is somewhat normal. In a hydraulic cylinder one side has more volume (area for fluid) than the other. The rod takes up space on the other side. Hydraulic power is a result of pressure pushing against a surface area. At a constant pressure the larger the surface area you push against the more power you have, the smaller surface the less power you have. It looks like you have 2 inch cylinders with 1 inch rods. So when you dump your bucket the oil is pushing against the 2 inch end of the rod (maximum power) when you retract you are only pushing on a fraction of the 2 inches because the rod is taking up space so you have half the power. Plus now you are lifting the weight of the bucket and what ever is in it. On top of that you are evacuating oil on the large volume end of the cylinder and if the hoses are to small or there is restriction through the valve the oil will have to fight its way out. That causes pressure/resistance.

The reason you dont see this lowering the loader arms (which really has the same issue) is you have the weight of the loader helping to push fluid out and the push side of your cylinders are under almost zero load until you reach the ground.

Thanks for that information Buck. I appreciate the insight. Sorry it took so long to acknowledge but the afore mentioned job had me away for awhile. Hope everyone has a great new year.
