Doyle culti drill no one-trick pony

The CD3001 culti drill, developed by Doyle Ag & Fabrication is no one-trick pony, as its developers explain.

The CD3001 culti drill is aimed at smaller landowners, by combining tillage and drilling in one machine

Developed in Australia’s Hunter Valley for local conditions, Doyle Ag & Fabrication’s dual-purpose CD3001 culti drill offers conventional tillage and direct drilling in one compact package.

Company director Kris Doyle says the dual- purpose machine is aimed at smaller landholders who find it difficult to justify the cost of two machines for both those purposes.

The CD3001 can carry out direct seed drilling, placing seeds accurately into high organic and trash loads, while still maintaining what its manufacturer describes as "excellent seed-to- soil" contact.

But with about 30 minutes of work, it can also be converted into a heavy-duty spring cultivator for all conventional cultivation requirements.

Based on Doyle Ag’s HD spring tine cultivator, the CD3001 is 3.0m wide and is able to be handled by a 100hp (75kW) tractor.


Its heavy-duty frame, built with galvanised grade 350 structural steel and heavy rectangular hollow steel, gives it a solid penetrating weight, while its five toolbars on 500mm spacings give it an excellent ability to handle trash.

The swept harrow bar ensures good seed coverage when drilling, and levelling when cultivating, while the full width crumble bar roller provides accurate ground following when drilling and excellent levelling capabilities while cultivating.

Seeding rows are spaced 150mm apart, and the unit is equipped with 20 x Heavy Duty S-tines (45x12mm + helper springs) to ensure seed penetration in hard, dry soils.

Doyle says the narrow lucerne points have low draft requirements, handle rockier conditions better, cut a neater seed slot than baker boots, and provide an un-matched seed environment, when compared to disc machines.

It was developed by the company after 20 years of agricultural contracting work, specialising in resource recovery, and fabrication of machinery for its own requirements.

"After constant requests for supplying custom machinery to other farmers and contractors, we have branched out into commercially supplying high quality contractor duty gear, simple and rugged in design, and made for Australian conditions," Doyle says.

"We have a heavy focus on designing one pass, multi-operation machines for reduction in diesel, labour, moisture/carbon/nutrient losses, and compaction."
