4 Row Fixed Hitch CultivatorPast Performers

Years In Service

1974 - 1992

All Bourgault Cultivators are designed to last 50% longer than most.

Commander 46-50

This five-plex unit follows contours with ease. The narrow main frame and small wing sections allows it to hug uneven terrain and provides you with even penetration. Result are an accurate seed bed for press drills or precise seed placement for air seeding.
The centre section and inner wings are equipped with walking axles that makes it float over rough terrain. The outer wing features a stabilizer wheel which eliminates all wing galloping.
The hitch design allows you to turn sharply without worrying about the tractor wheels hooking the hitch beams.

Commander 36-40 & Commander 34-38

Built to meet the toughest demands, both models feature walking axles on all sections so units float over the roughest terrain. Walking axles were designed extra strong to withstand the loads put on them in sharp turns.
All beams on the walking axle are 3/8 of an inch thick.
The Commander 36-40 has a 16 foot main frame where as the Commander 34-38 has a 13-1/2 foot main frame.

Commander 28-32

The Commander 28-32 is capable of performing both primary and secondary tillage and it's penetration ability is second to none.
Using a four slave series system to control its depth, there are no cables to stretch, and no linkages to wear out.

Model 24-28 & Model 18-22

Designed for the intermediate size farm, these models feature the same rugged construction and shank assembly as larger units.
The Model 24-28 was a triplex model and was ideal for tractors in the 100 to 135 horsepower range. The unit has excellent trash clearance and penetrating ability. The main frame was equipped with large 9.5L x 14 flotation tires and the wings have 7.50 x 14 tires. The cultivator has a 4 cylinder slave system and a hydraulic wing lift which is operated from the tractor seat.
The Model 18-22 had the same performance features as did the Model 24-28 but was a duplex type. This unit was ideal for tractors in the 75 to 100 horsepower range.

Commander 46-50

Field Finish - With the penetration capability and superior floatation of the Fixed Hitch 4-row series, accurate working depth is maintained. Combine these features with precise levelling ability and you are guaranteed finishing capabilities ideal for seed bed preparation and a field finish comparable to a 6" spaced cultivator.
Trash Clearance - A 4-row frame design and 8" shank spacing means superior shank spacing patterns, with a minimum of 24" between shank assemblies and 32" on the first row and most of the second. The 27" ground-to-frame clearance gives you nonstop, no plug performance. These features ensure excellent trash flow capability comparable to a three row chisel plow. For very heavy trash conditions, use a 4" sweep or a 2" reversible spike.
Penetration Capability - All Fixed Hitch 4-Row Series cultivators use a 230 lb. initial tension spring cushion shank assembly.
