Featured Content
Gearbox is rated for up to 50 PTO hp for longer life
The GM40 Series Grooming Mower rugged gearbox comes with a 6-year guarantee.
Ductile iron blade spindles with triple ball bearings
The spindles have a three-year warranty.
High speed blade to provide a quality cut
High blade tip speeds allow for better mowing quality at higher operating speeds and precise blade overlap work together to ensure performance and a quality cut.
Easy shield removal
The shield protecting the drive belt are easy to remove without the need of a tool. This provides easy access to the belt sheaves, belt, and spring-loaded idler.
Four caster wheels follow ground contours
By having four height adjustable caster wheels, the GM40 Series Grooming Mower follows ground contours and prevents scalping for even cut quality. Heavy tubular caster wheel arms are bolted to rail supports for long life.
Smooth, level finish
The floating top link on the GM40 Series keeps the deck tracking over ground contours for a level and smooth cut. For increased cut quality, connect your tractor’s 3-point hitch to the mower without an iMatch™ hitch system, taking advantage of the side-to-side floating clevis brackets.
Three blades per deck
To meet specific mowing needs, choose from two blade types:
- Low lift
- High lift (standard)
Deck design increases overall productivity
The deep deck design allows greater cutting volume and a cleaner cut. Offset gauge wheels reduce grass tracks.
An anti-scalping front roller kit can be ordered as attachment for field conversion for GM40 Series Grooming Mowers. The roller is attached to the front of the cutting deck to help reduce scalping in uneven terrain.
Each kit contains one roller.
The GM40 series grooming mower offer a deep high-grade steel deck, premium caster wheels, and heavy-duty construction for a longer durability. The floating lower hitch, high-lift blades, and parallel side frames create an extremely even cut and an even distribution of cut material, when mowing at higher speeds. For ease of attachment, it´s iMatch™ quick-hitch ready from the factory, without additional hardware.
Combine with a 6-year gearbox warranty and a 3-year spindle warranty, operator will have a rugged, high performing, and easy to use grooming mowers.
Prevents debris from flying out from under deck
A rear chain shield kit is available as an attachment for field conversion. It assists in preventing debris from flying out from underneath the deck of the rear-discharge grooming mowers.
