The jumpy tractor scraper

kerry cow

Hi lads .
I have a rubber scraper on a tractor for cleaning yards. With the last year it is constantly hopping and jumping up and down when pulling forward .It would wreck your head hopping and leaving muck behind .I have lengthened and shortened the top link .weight it down with tractor weights another , all no use. The old similar scraper never gave a v problem over the previous 12 years .
I was looking for genuine help and not smart comments .thanks

Would the rubber be worn down too much

Not sure if any help but I have a hydraulic top link on mine and can get the scraper level from the tractor seat and then when I turn it over for reversing scraping I can shorten the top link again from seat to get the blade level again and no hopping.
If you do get a hydraulic top link you won't regret it. Might/ should nearly solve it.

Lift the tractor arms slightly so that the scraper is more perpendicular and the toplink is loose when going forward.The rubber is just wearing uneven,maybe turn it around.

had a scraper here that worked ok till the rubber was replaced with a rubber cut from a lorry tire and the scraper was just useless after that jumping all the time
Can't offer a solution as I just stopped using it going forward and scrapped it since
Sorry I have no solution but I reckoned we should have put in a softer rubber ( I see ones for sale in co ops that I would have if they were available at the time - if I remember an angle grinder was destroyed in the cutting of that tyre)

It's just wear using tyres is a disaster if there's life left in the rubber trim the corners or give the whole length of it a good rub of a grinder and a bevel on both sides can be bits of stuff stuck in the rubber other than that new rubber

Rubber is pretty new .maybe by sounds of it , it's the tuff Ness of it that's the problem .no problem scraping back ward may turn it around . Good to hear other have same problem if you know what mean

Had the same problem when scraper was new but after the edges of the rubber wore in it was grand. Took a while though

As others said have to have the blade level when pulling. It usually means having the top link out to the full and you can judge it then if the sides are not hitting the ground when pulling and shorten top link enough then to get it just right.

What's the surface you are scraping like?

Good enough concrete .grooved in parts .may be it the type of concrete

Type of concrete shouldn't make any difference, if the surface was uneven or rough the scraper would be hoping though.

KC put the top link out to the last and then try scraping, then shorten top link, then try again, do it bit by bit. You'll find a sweet spot. Are the lift arms level? You'll get there eventually.
