A couple of brochure images for reference:

I have all the Westwood brochures showing all the attachments. There isn’t a plough shown, which possibly means it wasn’t suitable to pulling one. There is though the Rotodynamic Cultivator on an 11hp tractor so looking at the photos it is capable of pulling something through easy allotment ground.

For some sort of tractor comparison I have the Roper tractor brochures and the 18hp garden tractor can have either an 18hp twin Briggs or a 18hp Kohler Magnum engine. Tractor has a range of implements including a 10″ plough. Also has manual implement lift.

The Roper tractor is a stronger built machine than a Westwood and therefore can take a plough as intended.

Andy,

I think you are correct. The Westwood machine brochure shows a tractor pulling an implement through cultivated easy allotment ground and nothing tougher.

It certainly tells a lot that there isn’t a plough anywhere in the numerous Westwood brochures I have.

Westwood probably thought folk may wish to do some cultivating and introduced the tiller attachment in the above brochure photo to try and expand the tractors capabilities and appeal somewhat.

Only just picked up on this thread but the advice given re Westwood transmissions is good. The Peerless transaxles used in the majority of Westwoods and many other ride-on mowers is only rated for rolling loads (small trailers) and not ground engaging implements. Smaller Wheelhorses have similar transaxles but the larger ones have the much stronger cast iron cased units that will cope with reasonable draught loading.
US model ranges often distinguish between “Yard tractors” and Garden tractors, the latter often having draught capability eg the older Ariens ranges where the YT models were ride-on lawnmowers and the GT models were built to a much higher spec with some draught capability.

Unfortunately tractor shape doesn’t necessarily mean tractor capabilities!

Quite possibly a Gutbrod, imported and sold in the UK by Allen Power Equipment, often under the name Allen Moto Standard. They were a tough, proper miniature tractor quite capable of market garden work etc.
