Maybe his air filled tires are a little underinflated.

Re: Bouncy Bouncy! or ??
Any chance it had to do with the RPM's at which you were operating? I know at higher engine RPM's my FEL and especially my backhoe tend to operate too quickly and cause some rapid, violent movements that rock the entire tractor.

6 ply R4's can probably take a lot more air. Even 5 more pounds added while doing FEL work should stop a lot of the bobble head effect.
How about loading just in the front tires?

Gary , He was at maybe 1500 rpm .
But You are right about thehigh rpm causing the Fel to move fast and shake the tractor .
Have Blue .... I'll try various air pressures to see what happens . Bill might have a good point about the foam . It adds weight to the front and also acts as a damper on tire flex . All the best , John

Henro,
Air filled tires or larger tires will be bouncier than foam filled tires. Foam filled front tires also put more stress on the front end of the tractor as they don't act as much like a shock absorber and transmit more shocks/force up into the front end, etc.

Re: Bouncy Bouncy! or ??
Henro:
I have a 3130 HST and I've found that the loader controls are very sensative, and the loader moves FAST.
I've experienced the same bouncing if I lowered the loader too fast and then try to slow it down. /forums/images/graemlins/shocked.gif The downward momentum causes the front to bounce. I don't have filled tires.
