Why Guohaha
Eight Reasons
A sprayer is a pump, a tank and a boom. What separates one supplier from another is what happens before the steel is cut and after the first season ends.
Rolling, welding, coating and assembly under one roof — wall thickness and weld quality are our problem, not a supplier's.
Every boom is measured on water-sensitive paper at three pressures before crating.
Machine warranty with a numbered parts list; tank and frame covered for 24 months.
Nozzles, filters, tracks, sprockets, tyres, chains, ducts, blades, nets and tanks — dispatched in 48 hours.
Your RAL colour, badge, decals and manual language, with artwork approved on a painted sample.
Standard models ship in 15 days; frames and tanks are built ahead of the season.
Booms knocked down, machines lashed to steel skids, documents in a sealed tube — 12 units per 40 ft HC.
English, Spanish and French technical replies within one working day, with photos and video when useful.

Before
Send row spacing, slope, canopy height and water availability. We reply with two options — usually one cheaper than the other — and the reason each fits.
During
Photos at three stages: bare frame, painted machine, wet test. You approve the paint before the batch is released and see the pattern check before crating.
After
Parts by line number, video help for calibration and a written winter-service checklist. If something fails early, we replace the part and ask what happened.
