Grimme cs 150 or scanstone 4 Webber destoner

[Jimbo]

Currently running an older Grimme comi web chain driven machine and looking at a changing to a newer belt driven machine . At the moment I’m looking at either a Grimme cs 150 with 6-7 rows of vari stars then 36 mm web and also a scanstone 4 Webber with 37,37,37,32 mm webs.
Will be working in some fairly steep stony land for ware potatoes . Have no real experience of a star machine but would be interested in peoples views on both machines and output ect . Pretty much on the swing on which way to go at the moment . Cheers

Should add that scanstone is an open mouth one

Stars no good for stoney ground. Trialled a megastar and could hardly get the field dug at harvest. Stone stuck between haulm roller and second Web every few yards up the field, near drove me insane

Scanstone.

Stars will prob give more output but leave quite a tight bed compared to webs in my opinion, but some of our ground is on heavy side. Upkeep when get worn could be a nightmare, especially on stoney ground.

Scanstone 4webber with reversible scrubber web option would be best option

Plus they’re built here.

Yeh I’m starting to think maybe stars aren’t for me with the stone content .

 

[Hesstondriver]

always preferred webs here . Stars ok for declodding but let too many stones through as they wear . If your short on hp carrying enough muck over the stars can be a pain too .

scanstone would be my go to Gordon skee knows his stuff

We have 2 Grimme star machines , ok when no stones , would take the scanstone if I go my choice

Just to add options/confusion. Have you spoken to Billy about a standen?
They will have star only, stars and webs, or webs only machines.

I used to use a 150 cw grimme on the Yorkshire wolds. As long as you kept the machine full and kept the stars replaced if they were worn they didn’t let too many stones through.

Yes stars more pricey but last longer than webs, on the Cs you can adjust the stars. On stone free sandy soil we open stars up, and vice versa. Also run a combi web and all webber in the past, its down to the operator and conditions can get small stone coming through webs as well, depends on the size of the stone, flat ones are always a bugger. The Cs means we can get away with bed tiling as much now, especially with reversible scrubber web.

Their one with stars above a web look like an ok option.
