Quad 550

Vervaet has set the standard in slurry injection since as early as 1990, and today it leads the European market for professional self-propelled application machinery. To maintain and expand this market leadership we offer high-quality solutions and concepts which are innovative, easy to operate and service with low maintenance costs and a high residual value.
Introduced in 2021, the Quad 550 completes Vervaet’s range of professional manure application technology, the four-wheel machine fitting in alongside the three-wheel Vervaet Trike and five-wheel Vervaet Trike XL.

Engine and transmission

The Quad’s 13-litre 550hp 6-cylinder Volvo Penta engine boasts a phenomenal 2650Nm of torque at a stunningly low engine speed of just 1200rpm. Naturally with such a slow-running engine excellent fuel economy also comes as standard. Worldwide engine homologation backed up by a first-rate global service and maintenance network are additional benefits.

The new Vervaet made hydro-mechanical transmission combines the best of both technologies, utilising hydraulic motors to provide infinitely variable speed control to mechanical axles which deal with the high torque loadings associated with the demanding nature of high-output work. With this clever driveline concept the Vervaet Quad offers higher torque than any other self-propelled machine on the market in the crucial 5 to 15 km/h speed range. The Quad’s impressive traction and sheer pulling power is particularly valued whilst injecting slurry with rear-mounted cultivation tools. Diff-locks on each axle and a centre diff-lock are standard because getting stuck in muddy conditions just isn’t part of the plan.


The vast choice of tyres available for the Quad includes 900/60 R38, 900/60 R42, 1050/50 R32, 1000/55 R32, 1250/50 R32, the newest Mitas 1000/65 R32 as well as dual row crop tyres. When fitted with nearly all tyre sizes the Quad doesn’t exceed a 3m maximum transport width.

Ground pressure and maneuverability

The new Quad’s clever engineering stands out and makes it the lightest and strongest self-propelled machine in its class. It boasts an ultra-tight turning circle and can also be used in ‘crab steer’ mode so that each of its massive tyres runs in a different path, spreading its weight over the widest possible area to avoid soil-damage and compaction.


The Quad is fitted with the latest luxurious and ergonomic Claas cab which provides exceptional comfort and visibility. All controls easily fall to hand.

Vervaet’s own colour touch screen computer takes care of the machines main functions. Accuracy is particularly impressive, with the application rate controlled automatically by computer. GPS-steering systems can also be used for further levels of precision. The screen also displays important machine and spreader data from engine rpm and hydraulic system pressure to implement settings. It also supplies useful machine monitoring statistics such as fuel usage and work rate as well as customer or job specific data which is appreciated by contractors and farmers alike.

Slurry system

You’ll find more familiar Vervaet DNA right behind the radiator with the proven slurry system featuring a choice of Vogelsang and Börger 9,000 l/min pumps, or the SuperLoad system with 10” piping and a 12,000 l/min or 13,500 l/min Börger pump. These pump the slurry through the tried and tested Vervaet cyclone macerator or, as an option, a Vogelsang macerator fitted before the pump. A loading arm can make or break the efficiency of work and should be flawless and easy to use. It’s natural for operators to have their individual preferences, but we have managed to design a single loading arm suitable for every operator and situation. A loading arm that doesn’t hinder the driver’s visibility and that is fully road legal throughout Europe. Because we care for your safety and that of everyone around you in the yard and in the streets!

The Quad’s impressive traction and sheer pulling power is particularly valued whilst injecting slurry with rear-mounted cultivation tools. These are carried on a heavy-duty rear-linkage making it particularly quick and convenient to swap between, for example, an injector and a cultivator.
