Is this practice bad (Ramming something with FEL)

[Charlesaf3]

I don't wax my tractors. They are here to work. And they do.

But I try to avoid shock loads. Tractors (nor anything else) don't really respond well to dynamic shock loads. I'd push on anything. I wouldn't ram anything though. What's the difference? Pushing starts from zero speed. Ramming starts from speed. Theres a reason the working load limit on things is way below the shock load limit...

Really good point Charles

Geesh does every one (in the it's stupid camp) just scoop clean loam or something.

Only when not waxing....................

Your original question was "is this hard on the pistons?"

The answer is yes.

You have indicated you do not care and will continue to do it any way.

Your choice ... end of discussion.

Ditto.
I can't figure out why mswlogo even asked since he is determined to rationalize what he does

I figure shock loads can't be good. I try not to go fast over bumpy terrain for example with the FEL full.

As stated it is his tractor. I wouldn't ram stuff with mine but I might with his

I was cruising on my gravel road today with BoxBlade.



I rammed it slowly in low gear and it didn't cut.

Then I rammed it a little faster (maybe 4th gear pedal to metal).

ramming = high shock load will result in something breaking all at once.

as oppose to pushing steady no shock force you might bend some thing but it won't snap all at once.

I can tell you from experience ramming into piles of snow, dirt, etc can be harmful to your equipment. Years ago I had a Kubota L245DT which I purchased new and one winter we had so much snow I had to continually make room for more snow along the driveway and parking area by ramming the snow bank. Next thing I knew the front main crankcase seal was leaking engine oil. Consulted with the dealer and he claims the crank shaft loosened/destroyed the front seal when ramming the snow banks. Made sense to me. There was only about 200 hrs on the tractor at the time. I learned a lesson the hard way.

Good post.

Ok, so I'm almost at the point of buying a B2920, fel, backhoe, 5' box blade, 5' brush hog. I rented a 7510 to see how it handled with what I was doing and it worked fine.

The reason to get the machine is to work it. I'm making a road, of course in low gear, but dig/scrape/scoop/move dirt/rocks/logs/branches/roots(hardest).

I had and will have the tractor bouncing because I'm working it. If these things can't handle the work, I'm now concerned about buying one. I would think Kubota's engineers would design the tractor to limit it's own work before damage -
Guess my point is that if a new B2920 won't be able to handle anywhere from the light simple work to the hard taxing work, what good is it?
* Isn't it a tractor?

*Yes but the point some in this thread are missing is that it is not a BullDozer.

Nicely stated. Nearly everyone occassionally hits something that results in a shock load. Most of the time, there is no damage. If it is done intentionally, and repeatedly, the chance of damage becomes significant. To me "ramming" implies a willful attempt to use higher speed to disloge a relatively heavy or nonmoveable object. Tractor + speed = high kinetic energy. (I guess physics class paid off after all these years.)

Like you said, I will push and spin on FEL all the time. Occassionally, I give it a "nudge". Rarely, a serious "ramming".

Shock Loading
When a load is either moved or stopped, its static weight is magnified. Sudden movements can magnify the static weight several times. This magnification of static weight is termed "shock loading". Shock loading poses a danger to equipment and workers. The effects of shock loading can be instantaneous, or they may remain undetected unless the equipment is visually damaged. Avoiding shock loading requires careful planning and knowledge of equipment, rigging, and lifting practices.​

The damage done to crash test dummies is just another form of shock loading. If you like being a crash test dummy and have no idea how big the next "boulder" will be that your boxblade snags on, keep it up. Otherwise, get a serious piece of equipment that weighs 20k lb plus and you will have to snag something bigger before it breaks. Facts is that the nut behind the wheel is ultimately capable of breaking anything. Just look at the military. If you expect to keep your equipment around, caution is the better part of valor.​
