18inch Ransomes Gear Automaton

I recently acquired this 18inch Ransomes Gear Automaton. It is a very nice machine with the gear covers intact and not cracked. However there are two main issues with this machine. First and probably most serious is that the side frame which holds the entire cutting cylinder and roller housing etc has snapped. Luckily it's broken a little way up past the spindle aperture. It must have happened a long time ago as the snapped ends look very age dirty which is probably why it was parked way up the back of a barn. My question is does anyone have an opinion as to whether welding would be successful give the forces exerted in that area of use? Second the blades do not turn when the mower is pushed forward but might this be connected with the other problem ? I attach some photos. Any help would be appreciated as I've never had experience of that  type of welding. Many thanks Sean.

Welding is the only realistic

Welding is the only realistic option, I think, but I have seen many such repairs over the years and they seem to do the job very well. Last year, for example, I had a sideframe for a Silens Messor type of mower welded where the handles bolt onto it (bolt hole/eyelet broken off) and was very pleased with the results.

Modern welding techniques and the metals used make it quite easy for people in the know to make very good mends on cast iron like this and the join is likely to be more than strong enough. These welds can be made so that there is almost no visible evidence but in any case on your machine it's in a fairly well hidden spot. 

I wouldn't think that the break on your machine is stopping any movement at all on the cylinder, although it won't help of course. More likely there is corrosion on one or other component or the blade is too tight on the knife bed. Either should be relatively easy to put right.

Many thanks for that. I'll

Many thanks for that. I'll take it to a specialist welder. I'll strip the drive mechanism down to find why it doesn't work. The cylinder blade is fine to the base plate and turns as it should. The back roller moves backwards and forwards so I think you are right a component must have corroded as the blade is free but won't turn with the roller.

Hi Sean

Hi Sean

If your blade doesn't turn with the rear roller,then your gears are out of sink,and needs adjusting,while you are at it take the rear roller out and strip it down as secondly the drive pauls are either ceased, or even missing.When adjusting the gears down the side,the teeth should be just touching so that when they turn you should here a ringing sound,if you allow the teeth to sink to the bottom,then you will need a bloody elephant to pull it!

Kind regards
