Best Mowers for Tractors

Mowers come in several types, and the best one depends on what you are cutting. Pasture, lawn and brush each call for a different machine.

Key points

Rotary cutters suit rough pasture, finish mowers suit lawns and flails suit heavy growth.
Check PTO speed, hitch category and lift capacity before buying.
Keep every guard and driveline shield in place and keep bystanders far away.
Take extra care on slopes and walk the field before mowing.

What types of tractor mowers are there?

Rotary cutters, often called brush hogs, handle tall grass, weeds and light brush. Finish mowers cut a cleaner, lower lawn-style height. Flail mowers shred material and leave a finer mulch, and are used on roadsides and heavier vegetation. Belly mowers hang under some compact tractors.

Slope, terrain and what you cut should guide the choice. A cattle pasture needs a different mower than a lawn around a house.

Match the mower type to the habit as well. If you mow a lawn weekly, a finish mower makes sense. If you cut pasture two or three times a year, a rotary cutter is more practical. Buying the wrong type means disappointment with the cut or too much wear.

How do you match the mower to your tractor?

Check the implement's PTO speed and power requirements, the three-point hitch category and the weight. Ask the dealer or look at the manuals to confirm your tractor can lift and control it safely, especially when you transport it raised.

Width matters. A wide mower is quicker but needs more power and is harder to maneuver around trees and fences.

What features improve safety?

Look for guards, chains or deflectors that reduce thrown objects, and keep them in place. Rotary cutters can throw material at high speed. Keep people and animals well away while mowing.

The driveline should have complete shields. Never step over a turning shaft, and stop the PTO and engine before working near the blades.

Check that the mower is set at the correct working height and that the tailwheel or skid shoes are in good condition. Inspect the blades each time and replace any that are cracked, bent or missing. Uneven blades cause vibration that damages gearboxes.

How do you mow safely on slopes and rough ground?

Mowing on slopes raises rollover risk. Follow the manual's slope advice, keep the ROPS up and the seat belt fastened and avoid ditches and steep banks. Walk the field first to find rocks, stumps, holes and wire.

Mowing across a slope is often more dangerous than going straight up or down, depending on the machine. Check the manual and your extension office for guidance.

How do you maintain a tractor mower?

Grease fittings as directed, check the gearbox oil level with the type of oil the manual specifies and inspect blades for damage and balance. Sharpen or replace blades in matched sets, and tighten the hardware as specified.

Disconnect and block the implement before working under it. Never rely on hydraulics alone to hold up a raised mower.

Keep the mower clean. Built-up grass holds moisture and speeds rust, and a quick scrape and rinse after each use pays off. Store with the mower lowered to the ground or on a stand, and park it where children cannot reach.

Is a new, used or heavy-duty mower the right choice?

For occasional mowing of a few acres, a basic, well-built rotary cutter often serves well. Larger acreage, brush or frequent use justifies heavier construction. Look at gearbox design, frame, deck thickness and the guarding.

A used mower is fine if the gearbox is sound, the blade carriers are straight and the decks are not cracked. Ask the seller to run it.

Whatever mower you pick, make sure the driveline length, the shields and the hitch pins are all correct before the first cut. A mismatched driveline can bottom out or pull apart when the tractor turns or the mower is raised.

What mistakes should you avoid?

Do not mow with missing shields, mow around people or animals, run the PTO at the wrong speed or raise the mower with the PTO engaged. Do not hit hidden objects at full speed.

Matching mower to tractor, walking the field first and keeping shielding intact prevent most problems.

When to get help: Ask the dealer to confirm that a mower matches your tractor's PTO and lift capacity, and call a qualified mechanic for gearbox noise, bent blade carriers or hydraulic problems. Follow your operator's manual for slope limits and maintenance.
