Tractor jumping

[denmark53]

Drives fine with nothing on but kinda bunny hops with anything on the back, any ideas???

Tyre pressures will make it bounce and speed ,,has it got soft ride on the linkage

 

[denmark53]

No its an old tractor, just wondering if it could be a clutch issue

 

[agrimax]

What make,model? Does the problem occur with a load on the linkage or on the drawbar? Does the whole tractor bounce or is it the linkage jumping when loaded? Bit more info needed....

4wd?

 

[le bon paysan]

Tyres not round.

 

[Weare Cham]

Water in the tyres?

 

[Barleymow]

Ford?,
hydraulics set to load monitor ?

Its a renault 90 14, seems to happen with the tanker on it and the whole tractor seems to bounce

top link / load sensing valve on the 3pl. have driven a fiat/ universal like it @Andrew

Try the front tyre pressures 4 psi higher than the back tyres. used to work on MF's 61 and 62 series.

This is one of those mildly disappointing threads where the content isn't as interesting as the title suggests.

If it was happening with the load on the linkage, I'd have been thinking of Hesstondriver's suggestion but if on the drawbar, I can't see linkage or draft issues coming into play. What tyre pressures are you running on the tractor?

U sure its not the tanker? We had serious problems with bounce on the road until we changed the tanker tyres. Difference of day and night now
