Lumps and bumps in my lawn?

BML

When I walk over my lawn, which has not been touched since last autumn, I can feel loads of lumps and bumps.  Do I just mow it at the appropriate time or should I flatten it and if so flatten it with what because I don’t own a roller.  What about borrowing a whacker?

Obviously far to basic a question for this forum which I will now delete from my computer.

Hi everyone, does anyone recognise this plant, it's my sisters and she sent me the photo to ask

@Passionate Hi. Don't know if you have posted elsewhere as well as this but you didn't start a new thread of your own and this has combined with someone else's so you won't receive any answers to your query. If you still need an answer start a new post. Not something I can help you with unfortunately.

BML, the forum was down for a week so maybe it was missed. 
passionate, maybe an echium hit by frost?

Depends what the lumps and bumps are?  If just hillocks of rougher grass and the like, then raking them through should do it.  But if a result of subterannean activity then need to roll it....or put boards down and jump on them if just a few?

BML we explained  back in December why you shouldn't use a whacker

Yes indeed you did explain back in December but for some computer based reason I did not receive all of the answers but looking at them now I see that lawns are much more complex than I at first understood.  My latest post referred to the established lawn at the back of our dwelling and I'm inclined to just go out and mow it.  I really see little difference between laying a plank on the turf and jumping up and down on it and using a wacker but wave to your comments. 
At the time that the front lawn was laid I was recovering from flue and the gardener I was using could only work for two hours one day a week so bull headed as I am and against the advice of my wiser wife I pushed myself to finish the work.  I now see that I should have paid for some decent top soil which was more amenable to leveling than the soil I had but I will use the advice you gave and see what the result is.  I don't think that it will be ready for mowing for another few weeks yet.  Thank you all very much.

Dovefromabove. "A society grows great when old men plant trees whose shade they know they shall never sit in - Greek proverb".
I like your proverb but far from growing any trees in the village of Steventon Oxfordshire where  we have been smothered by money grabbing speculators intent upon covering the county in concrete we are losing trees as the incomers announce that they object to picking up leaves in Autumn and cut down those trees that have the effrontery to drop leaves on their gardens.

Mow it for a few times in the spring and see if you still have bumps and lumps. Soil will settle down a bit over the winter especially if it has been very wet. If the bumps and lumps are big, cut the turf and peel it back. Add more soil or take some away, level it off and then lay the turf back down, patting it well into place.  Any hollows can be filled with sieved topsoil (the grass will grow through). I would say that it takes a few seasons for a new lawn to come into its own so look on this as a longterm job.

Thanks for that.  The front looks good although when I wear thin shoes which tell me about the lumps and bumps but looking at the back lawn I see that there are patches that are a much lighter green that the rest of it.  Does that need some treatment.
