This Knight Demount Sprayer is optimised for the JCB 4000 series Fastrac. Choose either the compact folding “V-fold” boom that packs away behind the tractor or the overhead folding “Gull-Wing” boom for simplicity. 2500 litre or 3000 litre tank capacity combined with the optional 1300 litre or 1500 litre front tank will turn your Fastrac into a versatile, high capacity self-propelled sprayer.

Demounting the Knight Sprayer from the tractor is a simple process that takes little longer than a 3 point mounted implement, quickly releasing your tractor for other work.
