Tyre pressures for slurry spreading

[sanderzo]

I have Valtra T194 on trelleborg 650/65 r42 back and 549/65 r30 on front and was wondering what pressures I could drop them to for doing our umbilical slurry. The tractor will also need to put the pipes out with 1000m on the back and 600 on the front as well as being on the dribble bar.
Thanks in advance

Need to weigh it really. Could be a 3 meter dribble bar or a 24 meter. anyone would just be guessing unless you could say what weight you are carrying.

Are they VF Tyres

You may go and weigh it. Had a tractor here on similar sized bkts with a 10m dribble bar plus similar amount of pipe. They were running at 1 bar, didn’t have to drive very far on the road tho

Download the Trelleborg app and weigh the tractor, you really want each axles weight as a starting point. Then the app will tell you min pressures for speed and application, the Trelleborg app is pretty good, search for 'TLC plus'

For umbilical work u really should be runnin at least 800s or even 1050 tyres and on a light tractor not a 190hp

Easy to say that but most people have to use tractors for other jobs and if only on umbilical every now and then it wont stack up to buy tyres specifically for that job. Also depends what your ground is like but imo if just a tractor on umbilical needs tyres that big imagine the damage a tanker would do. So if you need tyres like that you should dig a bigger shite store and spread it when it's the correct time to

If its a contractor they need big tyres. If a contractor showed up here to spread with umbilical and hadnt big tyres they wouldnt be doin the job

If a contractor needed tyres that big then they shouldn't be driving in the fields in the first place. Store it till its dry enough. Spreading slurry onto wet fields is not only a waste of slurry but a good way of polluting the local river

Depends on how much pipe you’re pulling, surface conditions and banks. 1050’s won’t pull 800m of 5inch pipe up a damp bank as they won’t grip unless you ballast up which negates the benefits of wide tyres.

I’m not a contractor so I can’t justify having a spare set of wheels. I had a lighter tractor on 710s but wasn’t capable of doing all the other jobs on the farm so had to get something bigger. I’ve downloaded the trelleborg app now which was very helpful. If the big tractor makes too much mess I will have to resort to our new holland t4!

This is surely an excellent case for taking the time to adjust pressures using external or on-board compressor. It's not like it's every load like a tanker; once when finishing job. The pressure demands of loaded at speed v unloaded crawling are just so different.
